Aims. This study reports updates the previously published two-year clinical, functional, and radiological results of a group of patients who underwent transfibular total ankle arthroplasty (TAA), with follow-up extended to a minimum of five years. Methods. We prospectively evaluated 89 patients who underwent transfibular TAA for end-stage osteoarthritis. Patients’ clinical and radiological examinations were collected pre- and postoperatively at six months and then annually for up to five years of follow-up. Three patients were lost at the final follow-up with a total of 86 patients at the final follow-up. Results. A total of 86 patients were evaluated at a mean follow-up of 65.4 months (60 to 90). At five-year follow-up, statistically significant improvements (p < 0.001) were found in the mean American Orthopaedic Foot & Ankle Society Ankle

Large osteochondral lesions (OCLs) of the shoulder
of the talus cannot always be treated by traditional osteochondral
autograft techniques because of their size, articular geometry and
loss of an articular buttress. We hypothesised that they could be
treated by transplantation of a vascularised corticoperiosteal graft
from the ipsilateral medial femoral condyle. . Between 2004 and 2011, we carried out a prospective study of
a consecutive series of 14 patients (five women, nine men; mean
age 34.8 years, 20 to 54) who were treated for an OCL with a vascularised
bone graft. Clinical outcome was assessed using a visual analogue
scale (VAS) for pain and the American Orthopaedic Foot and Ankle Society

Aims. Infected and deformed neuropathic feet and ankles are serious challenges for surgical management. In this study we present our experience in performing ankle arthrodesis in a closed manner, without surgical preparation of the joint surfaces by cartilaginous debridement, but instead using an Ilizarov ring fixator (IRF) for deformity correction and facilitating fusion, in arthritic neuropathic ankles with associated osteomyelitis. Methods. We retrospectively reviewed all the patients who underwent closed ankle arthrodesis (CAA) in Ilizarov Scientific Centre from 2013 to 2018 (Group A) and compared them with a similar group of patients (Group B) who underwent open ankle arthrodesis (OAA). We then divided the neuropathic patients into three arthritic subgroups: Charcot joint, Charcot-Maire-Tooth disease, and post-traumatic arthritis. All arthrodeses were performed by using an Ilizarov ring fixator. All patients were followed up clinically and radiologically for a minimum of 12 months to assess union and function. Results. The union rate for Group A was 81% (17/21) while it was 84.6% (33/39) for Group B. All the nonunions in Group A underwent revision with an open technique and achieved 100% union. Mean duration of IRF was 71.5 days (59 to 82) in Group A and 69 days (64.8 to 77.7) in Group B. The American Orthopaedic Foot and Ankle Society (AOFAS)
Aims. There is little information about how to manage patients with a recurvatum deformity of the distal tibia and osteoarthritis (OA) of the ankle. The aim of this study was to evaluate the functional and radiological outcome of addressing this deformity using a flexion osteotomy and to assess the progression of OA after this procedure. Patients and Methods. A total of 39 patients (12 women, 27 men; mean age 47 years (28 to 72)) with a distal tibial recurvatum deformity were treated with a flexion osteotomy, between 2010 and 2015. Nine patients (23%) subsequently required conversion to either a total ankle arthroplasty (seven) or an arthrodesis (two) after a mean of 21 months (9 to 36). A total of 30 patients (77%), with a mean follow-up of 30 months (24 to 76), remained for further evaluation. Functional outcome, sagittal ankle joint OA using a modified Kellgren and Lawrence Score, tibial lateral surface (TLS) angle, and talar offset ratio (TOR) were evaluated on pre- and postoperative weight-bearing radiographs. Results. Postoperatively, the mean score for pain, using a visual analogue scale, decreased significantly from 4.3 to 2.5 points and the mean American Orthopaedic Foot & Ankle Society (AOFAS)
Aims. We hypothesized that there is no difference in the clinical and radiological outcomes using local bone graft versus iliac graft for subtalar distraction arthrodesis in patients with calcaneal malunion. In addition, using local bone graft negates the donor site morbidity. Patients and Methods. We prospectively studied 28 calcaneal malunion patients (the study group) who were managed by subtalar distraction arthrodesis using local calcaneal bone graft. The study group included 16 male and 12 female patients. The median age was 37.5 years (interquartile range (IQR) 29 to 43). The outcome of the study group was compared with a control group of ten patients previously managed by subtalar distraction arthrodesis using iliac bone graft. The control group included six male and four female patients. The median age was 41.5 years (IQR 36 to 44). Results. The mean American Orthopaedic Foot & Ankle Society (AOFAS)
Aims. To evaluate the donor site morbidity and tendon morphology after harvesting whole length, full-thickness peroneus longus tendon (PLT) proximal to the lateral malleolus for ligament reconstructions or tendon transfer. Methods. A total of 21 eligible patients (mean age 34.0 years (standard deviation (SD) 11.2); mean follow-up period 31.8 months (SD 7.7), and 12 healthy controls (mean age, 26.8 years (SD 5.9) were included. For patients, clinical evaluation of the donor ankle was performed preoperatively and postoperatively. Square hop test, ankle strength assessment, and MRI of distal calf were assessed bilaterally in the final follow-up. The morphological symmetry of peroneal tendons bilaterally was evaluated by MRI in healthy controls. Results.

Aims. We report the long-term clinical and radiological outcomes of a consecutive series of 200 total ankle arthroplasties (TAAs, 184 patients) at a single centre using the Scandinavian Total Ankle Replacement (STAR) implants. Patients and Methods. Between November 1993 and February 2000, 200 consecutive STAR prostheses were implanted in 184 patients by a single surgeon. Demographic and clinical data were collected prospectively and the last available status was recorded for further survival analysis. All surviving patients underwent regular clinical and radiological review. Pain and function were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS)
Introduction: An ankle fracture represents the most frequent osseous injury in both the elderly and non-elderly population. To date, only a limited number of retrospective studies have addressed medium-term outcome following ankle Open Reduction and Internal Fixation (ORIF). The purpose of this study was to assess residual pain and functional outcome 10 to 20 years after operative treatment of ankle fractures and to evaluate the incidence of symptomatic and radiographic ankle osteoarthritis (OA). Methods: We designed a retrospective study including all consecutive patients who underwent ankle ORIF between January 1988 and December 1997 in a University Hospital setting. Pilon and talus fracture as well as pediatric patients were excluded. Patients were seen by two senior residents 10–20 years after their index surgery. Residual pain was measured using the Visual Analog pain Scale. Function and general health status were assessed using the Olerud and Molander Ankle Score, the American Orthopaedic Foot and Ankle Society (AOFAS)
Talonavicular and subtalar joint fusion through
a medial incision (modified triple arthrodesis) has become an increasingly
popular technique for treating symptomatic flatfoot deformity caused
by posterior tibial tendon dysfunction. The purpose of this study was to look at its clinical and radiological
mid- to long-term outcomes, including the rates of recurrent flatfoot
deformity, nonunion and avascular necrosis of the dome of the talus. A total of 84 patients (96 feet) with a symptomatic rigid flatfoot
deformity caused by posterior tibial tendon dysfunction were treated
using a modified triple arthrodesis. The mean age of the patients
was 66 years (35 to 85) and the mean follow-up was 4.7 years (1 to 8.3).
Both clinical and radiological outcomes were analysed retrospectively. In 86 of the 95 feet (90.5%) for which radiographs were available,
there was no loss of correction at final follow-up. In all, 14 feet
(14.7%) needed secondary surgery, six for nonunion, two for avascular
necrosis, five for progression of the flatfoot deformity and tibiotalar
arthritis and one because of symptomatic overcorrection. The mean

The aim of this study was to compare the outcome of bilateral sequential total ankle replacement (TAR) with that of unilateral TAR. We reviewed 23 patients who had undergone sequential bilateral TAR under a single anaesthetic and 46 matched patients with a unilateral TAR. There were no significant pre-operative differences between the two groups in terms of age, gender, body mass index, American Society of Anaesthesiologists classification and aetiology of the osteoarthritis of the ankle. Clinical and radiological follow-up was carried out at four months, one and two years. After four months, patients with simultaneous bilateral TAR reported a significantly higher mean pain score than those with a unilateral TAR. The mean American Orthopaedic Foot and Ankle Society
The Pirani scoring system, together with the Ponseti method of club foot management, was assessed for its predictive value. The data on 70 idiopathic club feet successfully treated by the Ponseti method and scored by Pirani’s system between February 2002 and May 2004 were analysed. There was a significant positive correlation between the initial Pirani score and number of casts required to correct the deformity. A foot scoring 4 or more is likely to require at least four casts, and one scoring less than 4 will require three or fewer. A foot with a
The purpose of this study was to compare the clinical and radiological outcome of patients with intact, broken and removed syndesmosis screws after Weber B or C ankle fracture with an associated injury to the syndesmosis. We hypothesised that there would be no difference. Of a possible 142 patients who fulfilled our inclusion criteria, 52 returned for clinical and radiological assessment at least one year after surgery. Of these, 27 had intact syndesmosis screws, ten had broken screws, and 15 had undergone elective removal of the screw. The mean American Orthopaedic Foot and Ankle Society ankle/
Background. Acquired flatfoot deformity goes ahead with a partial or complete rupture and thus insufficiency of the tibialis posterior tendon. We present the results of flexor digitorum longus transfer and medial displacement calcaneal osteotomy to reconstruct the acquired deformity. Material & Methods. Twenty two patients (24 feet) with an average age of 58 (36–75) years were operated on for acquired flexible flatfoot deformity. Two patients had a bilateral procedure. Patients were seen pre-and postoperatively in order to evaluate following parameters: AOFAS
Background: While several studies in the last years tried to identify clinical limitations of patients suffering from end-stage ankle osteoarthritis (OA), very few attempted to assess foot and ankle function in a more objective biomechanical way, especially using dynamic pedobarography. The aim of the study was therefore to explore plantar pressure distribution characteristics in a large cohort of posttraumatic end-stage ankle OA. Method: 120 patients (female, 54; male, 66; 120 cases) suffering from posttraumatic end-stage ankle OA were included. The clinical examination consisted of assessment of the AOFAS
Summary: The SF-36, FFI, AOS and the AOFAS AHS were recorded pre and post-operatively in patients with end-stage ankle arthritis. Comparison of responsiveness shows the AOFAS score to be completely unresponsive. Introduction: Outcome studies should include both general health and disease specific measures. The Short Form 36 (SF36) is validated and widely used in musculoskeletal disease. A number of disease specific scores are available for the foot and ankle but, at present there is no widely agreed and validated score used specifically in end-stage ankle arthritis (EAA). Methods: 555 sets of pre and post-operative data on 239 EAA patients undergoing definitive treatment have been collected.

Introduction Nineteen consecutive patients underwent flexor hallucis longus (FHL) tendon transfer and medial displacement calcaneal osteotomy for the treatment of Stage 2 posterior tibial tendon dysfunction. Methods The FHL tendon was utilized for transfer because it approximates the strength of the posterior tibiais muscle and is stronger than the peroneus brevis muscle. Seventeen patients returned for follow-up examination (average 18 months). Results The AOFAS
Implant failure has become more common as the number of primary total ankle arthroplasties (TAAs) performed has increased. Although revision arthroplasty has gained attention for functional preservation, the long-term results remain unclear. This study aimed to assess the long-term outcomes of revision TAA using a mobile-bearing prosthesis in a considerably large cohort; the risk factors for failure were also determined. This single-centre retrospective cohort study included 116 patients (117 ankles) who underwent revision TAA for failed primary TAA between July 2000 and March 2010. Survival analysis and risk factor assessment were performed, and clinical performance and patient satisfaction were evaluated preoperatively and at last follow-up.Aims

Distraction bone-block arthrodesis has been advocated for the treatment of the late sequelae of fracture of the os calcis. Between 1997 and 2003 we studied a consecutive series of 17 patients who had in situ arthrodesis for subtalar arthritis after fracture of the os calcis with marked loss of talocalcaneal height. None had undergone any previous attempts at reconstruction. We assessed the range of dorsiflexion and plantar flexion and measured the talocalcaneal height, talocalcaneal angle and talar declination angle on standing lateral radiographs, comparing them with the normal foot. The mean follow-up was for 78.7 months (48 to 94). The mean American Orthopaedic Foot and Ankle Society
Introduction. Currently, a validate scale of ankle osteoarthritis (OA) is not available and different classifications have been used, making comparisons between studies difficult. In other joints as the hip and knee, the Kellgren-Lawrence (K&L) scale, chosen as reference by the World Health Organizations is widely used to characterize OA. It consists of a physician based assessment of 3 radiological features: osteophyte formation, joint space narrowing and bone end sclerosis described as follows: grade 0: normal joint; grade 1: minute osteophytes of doubtfull significance; grade 2: definite osteophytes; grade 3: moderate diminution of joint space; grade 4: joint space greatly impaired, subchondral sclerosis. Until now, the K&L scale has never been validated in the ankle. Our objective was to assess the usefulness of the K&L scale for the ankle joint, by determining its reliability and by comparing it to functional scores and to computerized minimal joint space width (minJSW) and sclerosis measurements. Additionally we propose an atlas of standardized radiographs for each of the K&L grades in the ankle. Methods. 73 patients 10 to 20 years post ankle ORIF were examined. Bilateral ankle radiographs were taken. Four physicians independently assessed the K&L grades and evaluated tibial and talar sclerosis on anteroposterior radiographs. Functional outcome was assessed with the AOFAS
Purpose. Total Ankle Replacement (TAR) is increasingly being offered to patients as an alternative to arthrodesis for the operative management of debilitating end-stage ankle arthritis. The Mobility Total Ankle System is a third-generation design consisting of a three component, cementless, unconstrained, mobile-bearing prosthesis. This study reports the early results of a multi-centre prospective study of the Mobility prosthesis. This is the first such report by independent researchers. Method. The senior authors implanted 86 consecutive Mobility prostheses. The underlying diagnosis was primary OA in 24 ankles, secondary OA in 47 ankles and inflammatory arthritis in 15 ankles. There were 41 males (Mean age 67 / Range 51–87) and 44 females (Mean age 60 / Range 29–72). The mean BMI was 28 (Range 22–36) for males, and 28 (Range 20–39) for females. Previous ankle operations were performed in 24 patients, 22 of which were for fracture fixation. Ankles were classified according to the COFAS end-stage ankle arthritis classification system. Coronal plane deformity was quantified pre-operatively. Clinical outcome was assessed using the AOFAS

History and Background: The HINTEGRA. ®. Total Ankle Prosthesis was designed in 2000 by Dr. B. Hintermann (Basel, Switzerland); Dr. G. Dereymaeker (Pellenberg, Belgium); Dr. R. Viladot (Barcelona/Spain); and Dr. P. Diebold (Maxeville, France), and is manufactured by Newdeal SA in Lyon, France. Design Features: The HINTEGRA. ®. Total Ankle Prosthesis is a non-constrained, three-component system that provides inversion/eversion stability. Axial rotation and normal flexion/extension mobility are provided by a mobile bearing element. Limits of motion are dependent on natural soft-tissue constraints: no mechanical prosthetic motion constraints are imposed for any ankle movement with this device. The HINTEGRA. ®. ankle uses all available bone surface for support. The anatomically shaped, flat tibial and talar components essentially resurface the tibia and talar dome, respectively, and wings hemiprosthetically replace degenerate medial and lateral facets (a potential source of pain and impingement). No more than 2 to 3 mm of bone removal on each side of the joint is necessary to insert the tibial and talar components. On the tibial side, most importantly, the bony architecture remains intact, and in particular, the anterior cortex is preserved. Perfect apposition with the hard subchondral bone is achieved by the flat resection of the bone and the flat surface of the component. Primary stability for coronal plane motion is provided by two screws inserted into the anterior shield, in the upper part of oval holes so that the settling process of the component is not hindered by axial loading. On the talar side, additional anterior support is provided by a shield, and pressfit is provided by the slightly curved wings. Two pegs facilitate the insertion of the talar component and provide additional stability, particularly against anterior-posterior translation. Another advantage of this concept is the instrumentation that allows reliable implantation of components. Technique: The prosthesis is implanted through an anterior approach. In the case of malalignment, ligamentous instability, and concomitant osteoarthrosis of the distal joints, additional surgeries are considered before prosthetic implantation. Complications: In the beginning, a major concern was the positioning of the talar component, which tended to slide too posteriorly while impacting and press fitting. With the addition of two talar pegs, the current design may resist such translational forces during press fitting. There is evidence that positioning of the talar component too posteriorly may cause pain and limit dorsiflexion of the foot (probably because the posterior aspects of the deltoid ligament are over-tensioned), thereby the intrinsic forces are also increased which may cause unacceptable high shear forces at the bone-implant interface and/or component instability. In all but one of the seven revised talar components (out of the author’s first 400 cases), the component was positioned too posteriorly. There is a potential risk for dislocation of the meniscal component either laterally or medially as long as no appropriate alignment and/or ligament balancing have been achieved during surgery. The author encountered this problem only in two of the first twenty cases; thereafter, no such complications occurred probably because of better understanding alignment and balancing the ankle. A potential concern in uncemented resurfacing prostheses is the use of screws that may create stress shielding. The HINTEGRA. ®. ankle, however, uses oval holes on the tibial side so that some settling of the component during osteointegration is possible. As screw fixation is located eccentric to the load transfer area, the potential for stress shielding is in addition minimized. Salvage of Complications: Special revision implants are available for salvage of failed components. On tibial side, components with a thicker plateau may serve to replace loosed bone stock and to get firm bony support more proximally, thereby preserving the original joint line (that means, the ankle ligaments are supposed to be properly used for stabilizing and guidance of the joint). On talar side, components with a flat undersurface allow flat resection of the talus, thus providing a wide area of bone support to the revision component. Results: Between 05/2000 and 12/2006, 340 primary TAA were performed in 322 patients (females, 165; males, 157, age 57.3 ± 13.4 years). Underlying diagnosis was posttraumatic osteoarthritis in 272 ankles, primary osteoarthritis in 26 ankles and inflammatory arthritis in 42 ankles. All patients were clinically and radiologically assessed after 6.2 (1.1–7.5) years, and survivorship analysis was calculated. Revision of a metallic implant or conversion into ankle arthrodesis was taken as the endpoint. The AOFAS
The ideal management of acute syndesmotic injuries in elite athletes is controversial. Among several treatment methods used to stabilize the syndesmosis and facilitate healing of the ligaments, the use of suture tape (InternalBrace) has previously been described. The purpose of this study was to analyze the functional outcome, including American Orthopaedic Foot & Ankle Society (AOFAS) scores, knee-to-wall measurements, and the time to return to play in days, of unstable syndesmotic injuries treated with the use of the InternalBrace in elite athletes. Data on a consecutive group of elite athletes who underwent isolated reconstruction of the anterior inferior tibiofibular ligament using the InternalBrace were collected prospectively. Our patient group consisted of 19 elite male athletes with a mean age of 24.5 years (17 to 52). Isolated injuries were seen in 12 patients while associated injuries were found in seven patients (fibular fracture, medial malleolus fracture, anterior talofibular ligament rupture, and posterior malleolus fracture). All patients had a minimum follow-up period of 17 months (mean 27 months (17 to 35)).Aims

Introduction. Patients with neglected rupture of the Achilles tendon typically present with weakness and reduced function rather than pain. Shortening of the musculotendinous unit and atrophy of the muscle belly in chronic rupture potentially leads to poorer recovery following tendon transfer. Few papers have looked at the outcomes of FHL reconstruction specifically in neglected TA rupture. Of those that have none report functional outcomes following a transtendinous repair. Methods. Twenty patients with irreparable unilateral tendoachilles ruptures treated with transtendinous FHL reconstruction between 2003 and 2011 were reviewed. Achilles Tendon Rupture Score (ATRS), AOFAS
Background. The adult acquired flat foot is caused by a complete or partial tear of the tibialis posterior tendon. We present the results of flexor digitorum longus transfer and medializing calcaneal osteotomy for recontruction of the deformity. Material & Methods. Twenty-six patients (31 feet) with an average age of 58 years (36–75) were operated for an acquired flat foot deformity. The patients were seen before surgery, one year after surgery and an average of 85 months after surgery to assess the following parameters: AOFAS Score, VAS Score for pain (0–10). Foot x-rays in full weightbearing position (dorsoplantar and lateral) were done at every visit in order to assess the following parameters: tarsometatarsale angle on the dorsoplantar and lateral x-ray, talocalcaneal angle on the lateral x-ray, calcaneal pitch angle and medial cuneiforme height on the lateral x-ray.

The aim of this study was to capture 12-month outcomes from a representative multicentre cohort of patients undergoing total ankle arthroplasty (TAA), describe the pattern of patient-reported outcome measures (PROMs) at 12 months, and identify predictors of these outcome measures. Patients listed for a primary TAA at 19 NHS hospitals between February 2016 and October 2017 were eligible. PROMs data were collected preoperatively and at six and 12 months including: Manchester-Oxford Foot and Ankle Questionnaire (MOXFQ (foot and ankle)) and the EuroQol five-dimension five-level questionnaire (EQ-5D-5L). Radiological pre- and postoperative data included Kellgren-Lawrence score and implant position measurement. This was supplemented by data from the National Joint Registry through record linkage to determine: American Society of Anesthesiologists (ASA) grade at index procedure; indication for surgery, index ankle previous fracture; tibial hind foot alignment; additional surgery at the time of TAA; and implant type. Multivariate regression models assessed outcomes, and the relationship between MOXFQ and EQ-5D-5L outcomes, with patient characteristics.Aims

Revision rates for ankle arthroplasties are higher than hip or knee arthroplasties. When a total ankle arthroplasty (TAA) fails, it can either undergo revision to another ankle replacement, revision of the TAA to ankle arthrodesis (fusion), or amputation. Currently there is a paucity of literature on the outcomes of these revisions. The aim of this meta-analysis is to assess the outcomes of revision TAA with respect to surgery type, functional outcomes, and reoperations. A systematic review was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, Medline, Embase, Cinahl, and Cochrane reviews were searched for relevant papers. Papers analyzing surgical treatment for failed ankle arthroplasties were included. All papers were reviewed by two authors. Overall, 34 papers met the inclusion criteria. A meta-analysis of proportions was performed.Aims

The aim of this study was to investigate whether on-demand removal (ODR) is noninferior to routine removal (RR) of syndesmotic screws regarding functional outcome. Adult patients (aged above 17 years) with traumatic syndesmotic injury, surgically treated within 14 days of trauma using one or two syndesmotic screws, were eligible (n = 490) for inclusion in this randomized controlled noninferiority trial. A total of 197 patients were randomized for either ODR (retaining the syndesmotic screw unless there were complaints warranting removal) or RR (screw removed at eight to 12 weeks after syndesmotic fixation), of whom 152 completed the study. The primary outcome was functional outcome at 12 months after screw placement, measured by the Olerud-Molander Ankle Score (OMAS).Aims

Between November 1993 and February 2000, a total of 200 consecutive STARs were carried out in 184 patients. Patients were followed up both clinically and radiologically, until death or failure, with time to decision to revision or fusion as the endpoint. Pain and function were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle and
Introduction. Historically, surgeons have focused on isolated simple coalition resection in symptomatic tarsal coalition with concomitant rigid flat foot. However, a review of literature suggests that coalitions with severe preoperative planovalgus malposition treated with resection alone are associated with continued disability and deformity. We believe that concomittant severe flatfoot should be considered as much as a pathological component and pain generator as the coalition itself. Our primary hypothesis is that simple resection of middle facet tarsal coalitions and simultaneous flat foot reconstruction can improve clinical outcomes. Methods. Thirteen consecutively treated patients (eighteen feet) were retrospectively reviewed from the senior author's practice. Clinical examination, American Orthopaedic foot and Ankle Society (AOFAS)
We describe a 63-year-old man who had xanthomatosis of the right tendo Achillis. He had undergone excision of the left tendo Achillis 17 years earlier without reconstruction for the same condition. The neurological history and examination were normal. Blood investigations showed hypercholestrolaemia, for which he was being treated with statins. He was referred with pain in the right tendo Achillis and problems with footwear. He was treated by excision of the right tendo Achillis, the xanthomatous nodules and the involved skin, followed by reconstruction with a cadaver bone-tendon graft. At follow-up eight months postoperatively, the scar had healed well. He walked without pain and could wear any type of shoe. Plain radiographs showed that the bone graft had healed.

Introduction. End-stage ankle osteoarthritis is a debilitating condition that results in functional limitations and a poor quality of life. Ankle arthrodesis (AAD) and total ankle replacement (TAR) are the major surgical treatment options for ankle arthritis. The purpose of the present study was to compare preoperative and postoperative participation in sports and recreational activities, assesses levels of habitual physical activity, functional outcome and satisfaction of patients who underwent eighter AAD or TAR. Methods. 41 patients (mean age: 60.1y) underwent eighter AAD (21) or TAR (20) by a single surgeon. At an average follow-up of 30 (AAD) and 39 (TAR) months respectively activity levels were determined with use of the University of California at Los Angeles (UCLA) activity scale. The American Orthopaedic Foot and Ankle Society (AOFAS)
Between 2000 and 2004 we used subtalar arthrodesis to treat 44 patients for continued pain after intra-articular calcaneal fracture. All the fractures were due to laboral accidents. Average time to union was 3 month(2 to 4 months). Complications were minor in 12 patients and major in 10 patients. Lenght of follow-up was 23 months.
Microtenotomy coblation using a radiofrequency (RF) probe is a minimally invasive procedure for treating chronic tendinopathy. It has been described for conditions including tennis elbow and rotator cuff tendinitis. There have been no studies to show the effectiveness of such a procedure for plantar fasciitis. Fourteen patients with plantar fasciitis with failed conservative treatment underwent. TOPAZ RF treatment for their symptoms between 2007 and 2008. The RF-based microdebridement was performed using the TOPAZ Microdebrider device (ArthroCare, Sunnyvale, CA). They were followed-up for up to six months thereafter. Pre-operative, three and six months post-operative VAS, AOFAS ankle-hindfoot and SF-36 scores were analysed. There were six men and eight women, with an average age of 44.0 years (23–57). There were 15 feet, with six right and nine left feet. They were followed up for six months post-operatively. There was a significant improvement in mean pre-op and six-month VAS scores from 8.13 to 3.27(p=0.00), and AOFAS

Background: Open Tibiotalocalcaneal fusion has been shown to be an effective treatment for arthritis and complex foot deformities, but with a high complication rate. We are reporting the results of the first 14 feet undergoing arthroscopic tibiotalocalcaneal arthrodesis. Methods: Retrospective review identified 13 patients who had 14 combined ankle and subtalar arthrodeses performed arthroscopically, with no bone grafting. The procedure was performed for the treatment of combined ankle and subtalar arthritis or hindfoot deformity. The majority had fixation using 6.5mm ASNIS screws (Stryker (Kalamazoo, Michigan, USA)) introduced percutaneously, although in one case a hindfoot nail was used. Outcome was assessed by a combination of chart review, clinical examination and questionnaire. Follow up averaged 16 (6 to 33) months. Results: At follow up average patient satisfaction was 9.7/10. Average time to fusion was 12 (10–20) weeks. The average postoperative American Orthopaedic Foot and Ankle Society (AOFAS)

Triple arthrodesis is the most effective treatment resource for restoring shape and stability to the hind-foot. It is used in order to achieve a plantigrade foot, aligned, stable and painless, in the treatment of various pathologies. However, it has the effect of changing the dynamic mobility of the foot and diminishes the adapting ability to uneven ground, influencing the outcome. Opinions differ on the necessity of internal fixation to maintain the proper alignment of the hind-foot and improve consolidation, influencing the results. The authors reviewed the patients who underwent triple arthrodesis between 01/01/1998 and 31/12/2008. Of a total of 46 patients 28 were reviewed, corresponding to 29 feet that underwent 36 interventions (7 recurrences). Patients were divided into two groups according to whether or not the placement of internal fixation. They were evaluated according to the AOFAS ankle and
Locked plates confer angular stability across fusion sites, and as such are more rigid than either screws or intramedullary nails. This gives the advantage of reducing motion to enhance union rates and potentially allowing early weight bearing. The Philos plate (Synthes) is a contoured locking plate designed to fix humeral fractures but which also fits the shape of the hindfoot and provides strong low profile fixation. Its successful use for tibiotalocalcaneal (TTC) arthrodesis has been reported. Our aim was to prospectively evaluate the use of the Philos plate in hindfoot arthrodesis Twenty-one hindfoot arthrodeses were performed using the Philos plate between Oct 2008 and Jan 2010. Patients were followed up for a minimum of 1 year and had preoperative and 6 monthly AOFAS
Introduction. Medial calcaneal displacement osteotomy with an FDL tendon transfer is a common method of correcting pes planus deformity secondary to grade II tibialis posterior dysfunction. There is currently no evidence that calcaneal displacement alters the centre of pressure in the foot from a medial to a more central position as the normal shape is reconstituted. Materials and Methods. We prospectively evaluated 12 patients undergoing flatfoot reconstruction. Each patient had a preoperative AOFAS
Twenty-four replacements were performed in 19 patients (13 female: 6 male), with average age of 33 years (18-40). All had severe polyarticular rheumatoid arthritis. Pre-operatively 12 ankles had no angular deformity, 9 were in valgus and 3 in varus. All had associated hindfoot disease. Some of these patients are part of two larger studies of the Scandinavian Total Ankle Replacement (STAR) and the Buechel-Pappas (BP) replacement. In this group there were 20 STAR and 4 BP replacements. Average follow-up was 62 months (36 to 120). Twenty-one replacements had good pain relief and function. The AOFAS
The Achilles tendon is the most commonly ruptured tendon in the body and yet its management remains controversial due to potential surgical complications. We believe that primary repair using LARS ligament augmentation, combined with early mobilisation will significantly reduce all these potential problems and lead to improved functional outcomes. Nine patients with acute Achilles tendon ruptures underwent primary repair using augmentation with a Ligament Augmentation and Reconstruction System (LARS) ligament. Day one postoperatively each patient was started on active range of motion exercises. Clinical parameters, isokinetic strength and outcome measurements (The American Orthopaedic Foot and Ankle Society (AOFAS) ankle and
Outcome studies of the Ponseti method from various centres have reported success rates ranging from 85–95%. The vast majority of patients can expect a supple, functional and pain free foot. The small percentage of feet that are resistant to Ponseti treatment often require open surgical correction, leading to scarring and stiffness. We present a method of correcting resistant equinus by a tenotomy and calcaneal pulldown technique. This method is complimentary to the Ponseti technique. Method. Prospective study of 40 feet in 28 patients who underwent an Achilles tenotomy and calcaneal pulldown technique. The indications for this method were resistant equinus and problems with casting. Feet scored with the Pirani method. Under a general anaesthetic, a standard Achilles tenotomy was performed. The equinus deformity corrected by traction of the calcaneum with a “catspaw” retractor and dorsiflexion of the forefoot. Further treatment was performed according to the Ponseti method. The Ponseti clubfoot brace was used to maintain correction. Results. 28 patients 40 feet. Mean preoperative Pirani score:3.0 (left 3.0, right 3.1 range 1.5–6). Mean preoperative
Introduction. The Mobility™ prosthesis [Depuy] is the most extensively used TAR in the UK, though there are few published results. We present our complete experience of the Mobility prosthesis in a diverse population. Methods. From March 2005 to December 2009, 84 consecutive Mobility ankle replacements were performed by the senior author, in 79 patients (28 female, 51 male) with mean age 64.5 years (43–80). This complete cohort included the first and last cases with this implant. Mean follow-up was 50.1±18.2 months (range 14–86). Patients with ankle replacements in situ, were reviewed clinically and radiologically. Clinical outcome measures were: AOFAS score, MOXFQ (adapted for the ankle), and VAS for pain. Post-operative radiographs were reviewed to assess component position and examine for zones of lucency. Results. At final review, 1 patient had died (unrelated), 13 had been revised as follows:
. Arthrodesis 7. Further TAR 2. Talus only revised 1. Tibia only revised 1. Amputation 2 (one for an unrelated problem). Exchange of bearing had been carried out in 4. Intra-operative malleolar fractures occurred in 4.8% and were internally fixed. 62 patients attended for clinical review and 8 completed postal questionnaires. At follow up:. Mean AOFAS
Subtalar distraction bone-block arthrodesis for malunited calcaneal fractures was performed in 31 patients (26 men, five women), with a mean age of 38.5 years. The mean time from injury to arthrodesis was 36 months. There were no cases of nonunion. One patient had an early dislocation of the bone block requiring a repeat arthrodesis, and one had a soft-tissue infection. The mean AOFAS
Advances in implant design and instrumentation have led to total ankle replacement (TAR) becoming an attractive alternative to ankle fusion in selected cases. We present the short-term results for Mobility TAR with clinical and radiological findings. Methods: Prospective study from Dec 2004 to Dec 2007. Single surgeon, anterior approach to the ankle.

Our purpose was to evaluate the use of indirect and closed reduction with Ilizarov external fixator in intraarticular calcaneal fractures. In a period of 3 years, 16 patients with 18 intraarticular fractures of calcaneus (eleven type III and seven type IV according to Sanders classification) were treated with the Ilizarov fixator. Twelve patients were male and four female. The average age was 42 years (range 25 – 63 years). Three fractures were open. Fractures were evaluated by preoperative radiographs and CT scans. Restoration of the calcaneal bone anatomy was obtained by closed means using minimally invasive reduction technique by Ilizarov fixator. Arthrodiatasis and ligamento-taxis, and closed reduction of the subtalar joint were performed in 14 cases. In 4 cases the depressed posterior calcaneal facet was elevated by small lateral incision and stabilized in frame by wires. Postoperatively, partial, early weight bearing was encouraged in all patients. The mean follow-up period was 1,5 years (range 1 – 3 years). The AOFAS Ankle –
Background: Long term follow up data on patients following ankle fracture is scarce. As a follow on from a year long prospective audit of patients admitted to a trauma unit data was collected on a cohort of such patients at a minimum of 4 years post injury to ascertain functional outcome. Methods: All patients with ankle fractures requiring admission to the Royal Preston Hospital in the period August 2004 to August 2005 were identified. Patients with multiple injuries were excluded. One hundred and one patients were confirmed as fulfilling the criteria that all medical notes were present and the patient had a principle injury of a malleolar fracture. Patients were then invited to a follow up clinic. Functional outcome relating to work and leisure pursuits, the American Orthopaedic Foot and Ankle Society
Aim: Our purpose was to evaluate the use of indirect and closed reduction with Ilizarov external fixator in intra-articular calcaneal fractures. Materials and Methods: In a period of 5 years (2004–2008), 26 patients with 29 intra-articular fractures of calcaneus (eighteen type III and eleven type IV according to Sanders classification) were treated with the Ilizarov fixator. Twenty-one patients were male and five female. The average age was 45 years (range 22 – 67 years). Five fractures were open. Fractures were evaluated by preoperative radiographs and CT scans. Restoration of the calcaneal bone anatomy was obtained by closed means using minimally invasive reduction technique by Ilizarov fixator. Arthrodiatasis and ligamentotaxis, and closed reduction of the subtalar joint were performed in 24 cases. In 5 cases the depressed posterior calcaneal facet was elevated by small lateral incision and stabilized in frame by wires. Postoperatively, partial, early weight bearing was encouraged in all patients. Results: The mean follow-up period was 2,1 years (range 1 – 4 years). The AOFAS Ankle –
Chronic Achilles tendonosis is a common but difficult condition to successfully treat. Platelet rich plasma (PRP), a concentrated bioactive component of autologous blood that is rich in cytokines and other growth factors, was examined in this study to assess its ability to promote healing in severe cases of Achilles ten-donosis resistant to traditional non-operative treatment paradigms. Twenty-seven patients (16 males 11 females) with an average age of 46 (36–66) and who had failed an average of 8 months (6–10) of standard non-operative management for Achilles tendonosis (rest, heel lifts, PT, NSAIDS, cam walker / cast immobilization, night splinting, local modalities) were prosepectively included in the study. All patients had pre-treament MRI and ultrasound studies and clinical scoring was completed using the AOFAS
Introduction: Arthrodesis has been recommended for the treatment of end-stage osteoarthritis of the ankle joint, especially as the results of prosthetic ankle replacement are not comparable with those achieved with total hip or knee replacement. In vitro studies revealed that ankle arthrodesis restricts kinematics more than total ankle replacement in terms of range of motion as well as movment transfer. However, little is known about in vivo gait patterns in patients with arthrodesis of the ankle joint. Aim of this retropective study was to determine plantar pressure distribution in patients who underwent ankle arthrodesis with a standardized screw fixation technique in a single surgeon population. Methods: 21 patients (7 male/14 female) who underwent isolated unilateral ankle arthrodesis with 3 crossed 7,3 mm AO screws (Synthes Gmbh, Austria) in a standardized technique by a single surgeon between October 2000 and January 2008 have been included in this study. At a mean follow-up of 25 months (range 12 – 75) pedobarograhy (Novel GmbH., Munich), clinical evaluation using the AOFAS
Simultaneous arthrodesis of the ankle and subtalar joints is an established treatment option for combined ankle and subtalar arthritis or complex hindfoot deformities. The use of a curved intra medullary nail has potential advantages in terms of stability, hindfoot alignment and avoidance of the lateral neurovascular bundle. We devised a comparative description of the results of hindfoot fusion using a curved locking nail before and after the introduction of anatomically specific modifications to the device through a retrospective review of notes and radiographs of patients undergoing simultaneous ankle and subtalar fusion by retrograde intramedullary nailing using an ACE¯ (Humeral Nail. Patients undergoing the same procedure using the Tibiotalocalcaneal [TTC] Nail System [DePuy] were recruited and studied prospectively. The outcome was assessed by a combination of notes review, clinical examination and telephone questionnaire. Between 1996 and 2004, 71 arthrodeses in 67 patients have been performed. The average follow up is 27 months [3-73] and mean age 58 years. Fifty-two arthrodeses utilised the ACE humeral nail and nineteen used the newer TTC nail. Both nailing systems are locked proximally and distally and provide a short radius laterally directed distal curve. Mean time to union is 4.3 months [3-10]. Average AOFAS

Chronic ruptures of the tendo-achilles in young individuals pose difficult therapeutic problems. Surgical repair Is necessary to achieve optimum functional results. We present our results using a modified Bosworth technique using a ‘turn-down’ strip of gastrosoleus aponeurosis. Materials and methods: 11 patients (9 Males:2 Females) Age range: 23–51 (average 36) Time since rupture: 9–20 weeks (average 13). All had pain, weak or absent push-off and restricted ADL. Technique: Posterior midline incision – rupture exposed, ends debrided – 1” strip of gastrosoleus aponeurosis about 2–3” long – detatched proximally ‘turned down’ with fascial surface anterior. This modification was to avoid tissue bulge at proximal end of incision. The fascial strip was approximated with delayed absorbable sutures. The plantaris was used to supplement the repair when possible. Cast-bracing for 9 weeks. FU – 12–42 months, minimum 12. All patients independently assessed at one year. AOFAS
Introduction. To achieve tibiotalocalcaneal arthodesis, implants described range from external fixator, compression screws and anterior plate and the more recent retrograde calcaneal locked intramedullary nail. Our aim is to assess the outcome of the AO cannulated blade plate for tibiotalocalcaneal arthrodesis. Patients and methods. Four tibiotalocalcaneal arthrodeses were performed in three patients. The operative technique involves lateral approach to the distal fibula that was osteotomised and used as bone graft. The articular cartilage of ankle and subtalar joint was removed using an osteotome and congruent surfaces achieved. AO cannulated blade plate was applied on the lateral aspect to achieve compression. The postoperative protocol included a plaster cast for three months, followed by mobilization out of plaster. Results and discussion. At the mean follow up of 10 months (range five to fourteen months) all patients were pain free on full weight bearing. The union was achieved at three months which was confirmed clinically and radiologically. There was no infection, wound breakdown, or loss of position at the ankle or subtalar joints.

Aim: To report the clinical and radiological results of patients undergoing hindfoot fusion using an intramedullary nail. Methods: Retrospective review of notes of patients undergoing combined ankle and subtalar arthrodesis using retrograde intramedullary nailing. The procedure is performed mainly for the treatment of complex hindfoot deformities or following failed total ankle arthroplasty. Outcome was assessed by notes review, clinical examination and telephone questionnaire. Results: Between 1995 and 2001 56 arthrodeses in 52 patients have been performed. The average follow up is 3 years. Approach to the joints was via an anterolateral incision unless previous surgery dictated otherwise. All cases utilised an ACE¨ humeral nail which was locked proximally and distally. Most procedures utilised bone graft from the þbula, proximal tibia, iliac crest or allograft femoral head. Mean tourniquet time was 114 mins. Post-operative management generally consisted of 3 months plaster immobilisation. Post-operative complications included deep infection, amputation, stress fracture, non-union &
prominent metalwork. At review 90% of patients were satisþed and approximately 90% felt the pain level &

Introduction: Adult acquired flat foot deformity is recognised as a spectrum of pathology related to tibialis posterior dysfunction (TPD) and plantar ligament insufficiency. Cobb has described a method of reconstruction in pure Johnson and Strom type II TPD using a split Tibialis Anterior musculo-tendinous graft. Methods: We describe a prospective study of 32 patients treated by the Cobb technique and a medial displacement translational os calcis osteotomy for Johnson and Strom type II TPD. There were 28 females and four males (age range 44–66, average 54) each with unilateral disease. The average follow up was 5.1 years, range 3 to 7.2 years. Each patient had failed conservative management and the staging was confirmed clinically and radiologically (ultrasound scanning and MRI). The surgery was performed as described by Cobb but with a bone tunnel in the navicular rather than the medial cuneiform. Postoperative immobilisation in plaster was for eight weeks followed by orthotics and physiotherapy. Results: All the os calcis osteotomies healed uneventfully. 29 of the 32 patients were able to perform a single heel rise test (none prior to surgery) at twelve months follow-up. These patients had grade 5 power of the tibialis posterior tendon. The others had grade 4 power and were also happy with the result. The mean American orthopaedic foot and ankle society (AOFAS)
Introduction: We report the clinical and radiological results of 137 AES Total Ankle Replacements (TAR)(Biomet, Europe) over a 4-year period. Methods: 134 patients underwent 137 Total Ankle Replacements. There were 47 females and 87 males. Three patients underwent bilateral procedures. The mean age of the patients was 64 years (48–78). The main indication for surgery was post-traumatic arthritis other indications included primary arthritis, inflammatory arthritis, haemophilia, haemochromatosis, polio, cavo-varus deformity and revision of a loose STAR. The pre-op coronal deformity ranged from 20 degrees varus to 40 degrees valgus. The same surgeon performed all operations. All patients had a clinical and radiological follow-up at 3, 6 and 12 months then annually, thereafter. Results: At a mean time to follow up of 18 months the mean AOFAS
Purpose: The global utilization of total ankle arthroplasty (TAR) has been increasing over the past decade; however there are a limited number of published prospective studies assessing intermediate and long term outcomes. The purpose of this clinical series is to prospectively review the mid-term clinical and radiographic outcomes of the Scandinavian Total Ankle Replacement (STAR) performed at two Academic Canadian University Centres. Method: Between 1998 and 2005, 113 STARs were implanted into 99 patients at two Canadian centres. Prospective clinical and radiographic follow-up was performed. Validated and non-validated outcome questionnaires consisting of the AAOS foot and ankle questionnaire (a composite questionnaire made up of unaltered versions of the SF-36), AOFAS
Aim: To identify factors which improved outcome following surgery. Method: Between 1994–2000, 28 patients with 30 displaced intra-articular fractures of the calcaneum were treated with open reduction and internal fix-ation at our hospital (mean, 45 years). We reviewed 20 patients within the Shropshire region over a 3.6 average follow-up period using 4 recognised
Aim. To report the clinical and radiological results of patients undergoing hindfoot fusion using an intramedullary nail. Methods. Retrospective review of notes and radiographs of the patients of 2 surgeons who perform combined ankle and subtalar arthrodesis using retrograde intramedullary nailing with an ACE® humeral nail. The procedure is performed mainly for the treatment of combined ankle and subtalar arthritis or complex hindfoot deformities. Outcome was assessed by a combination of notes review, clinical examination and telephone questionnaire. Results. Between 1995 and 2001 54 arthrodeses in 51 patients have been performed. The average follow up is 3 years. Approach to the joints was via a vertical anterolateral incision unless previous surgery dictated otherwise. All cases utilised an ACE® humeral nail which was locked proximally and distally. Most procedures utilised bone graft from the fibula, proximal tibia, iliac crest or allograft femoral head. Mean tourniquet time was 122 mins. Intra operative complications included one fractured tibia and one fractured medial malleolus. Postoperative management generally consisted of 3 months plaster immobilisation. Only 3 cases were immobilised significantly longer than this. Postoperative complications included deep infection, amputation, stress fracture, non-union &

This retrospective study analyses the results of subtalar bone block distraction arthrodesis used in the treatment of late complications of calcaneal fractures, acute severely comminuted fractures, nonunion (and malunion) of attempted subtalar arthrodeses, avascular necrosis of the talus, and club-foot deformity. Of 39 patients (41 feet) who had this procedure, 35 (37 feet) returned for follow-up after a mean of 70 months (26 to 140). There were 24 men (25 feet) and 11 women (12 feet) with a mean age of 41 years (16 to 63). Each completed a standardised questionnaire, based on the hindfoot-scoring system of the American Orthopaedic Foot and Ankle Society and were reviewed both clinically and radiologically. Of the 37 operations, 32 (87%) achieved union. The mean
Surgical resection of the persistently painful talocalcaneal tarsal coalition has not been shown to reliably relieve symptoms in patients with coalitions that are large and have associated hindfoot valgus and subtalar arthrosis. It has been recommended that these patients undergo triple arthrodesis, a procedure that is known to lead to premature arthrosis of the ankle joint. To avoid additional stress on this important joint, treatment of this patient group using calcaneal lengthening osteotomy (CLO), with or without resection of the coalition, has been performed at our institution for the last 15 years. A retrospective review of all patients with talocalcaneal coalitions who had undergone CLO was performed. Clinical and radiographic records were reviewed. Demographic data, and pre- and post-operative pain and function were recorded. Pre- and post-operative radiographs and computed tomography (CT) scans were reviewed and measurements recorded. CT scans were used to calculate the degree of hindfoot valgus and the size of the coalition. Patients were invited to return for clinical examination and follow-up x-rays if two years had passed since their operation. They completed American foot and ankle
Purpose: To investigate the outcome of tibiotalocalcaneal (TCC) fusion using the retrograde intramedullary nail (IMN). Methods and results: We reviewed clinical and radiological outcome of 42 patients who underwent TTC fusion with a retrograde IMN in a single health region from 1996 to 2003. Out of 42 patients, four patients died of unrelated causes and two patients were lost to follow up. Finally, 36 patients (20 males, 16 females) were followed up. Mean age was 63 years and the follow up averaged 10 months. Degenerative arthritis (primary and post traumatic) and rheumatoid arthritis made up the majority of the preoperative diagnoses. Clinical outcome was assessed using the AOFAS
Introduction. Considerable controversy exists with regard to the surgical management of displaced intra-articular calcaneal fractures. Protagonists for internal fixation would suggest there is sufficient evidence to expect better functional outcomes with surgery. However, this is not conclusive. Aim. To identify factors which improved outcome following surgery. Method. Between 1994–2000, 28 patients with 30 displaced intra-articular fractures of the calcaneum were treated with open reduction and internal fixation at our hospital (mean age 45 years).

Tibiotalocalcaneal (TTC) fusion is indicated in rheumatoid patients with combined ankle and subtalar disease, particularly when severe deformity is present. In theory, if bone stock is good, a staged subtalar/triple arthrodesis followed by total ankle replacement (TAR) can be used. This is so rarely the case that the author has no experience of this. TTC fusion is also useful in rheumatoid patients with previous joint sepsis, to salvage a failed TAR and to salvage a non-united ankle fusion. It allows early weight bearing, which is valuable in those patients who have multiple joint, particularly upper limb, involvement. In our study, 18 patients underwent 21 TTC fusions from August 1988 to September 2002. The average age was 48 years (range 23–90). Nine patients had undergone previous hindfoot procedures, five were smokers, one was diabetic and one had chronic renal failure. Surgery was performed under GA with tourniquet. Patients were reviewed using a modified American Orthopaedic Foot and Ankle Society (AOFAS)
Purpose of Study: Assessing short and long term eficacy of Extracorporal Shock Wave Therapy (ESWT) as a treatment for recalcitrant plantar fasciitis (PF). Methods: Prospective follow up of 63 heels among 50 patients with persistent PF patients, (mean age 57.2±10.5); symptoms’ duration 15.8±14.3 months, resistant to non-operative treatment modalities including steroid injections. All patients underwent thorough physical examination and AOFAS
Background: Osteoarthritis (OA) may affect large and small joints and is common final pathway of large array of conditions. OA of the large joints includes mainly hip, knee, shoulder and ankle. The treatment of OA of the ankle is limited and the surgical treatment is usually salvage procedure as fusion. Therefore there is a need for an efficient conservative treatment of the ankle OA. Aims: The objective of this clinical trial was to evaluate the symptomatic efficacy of intraarticular preparation containing Sodium Hyaluronate, in the treatment of OA of the ankle. Methods: The study was conducted on patients who visited our out-patients clinic under the direct supervision of the principle investigator. The male or female patient aged between 30 and 80 suffering from osteoarthritis of the ankle joint of radiographic severity II or III or IV according to Kellgren and Lawrance, suffering from one or more of the following conditions of the ankle joint: swelling, tenderness or pressure, and/or pain on motion or at rest, who have clinical history of ankle pain for over 6 months. Intraarticular injections of 25 mg Sodium-hyaluronate in 5 following weeks were administrated to 16 patients, 31–79 years old (average 43 years) suffering from pain in the ankle, 9 months to 27 years. 12 patients after operation, 4 with no trauma history. Follow-up visits were performed 1,2,3,4,7 months post treatment and included clinical evaluation and score scale. Results: Global assessment showed in 13 out of 16 patients improvement in the motion range (20%) and significantly reduction of the OA symptoms according to the score: 2–3 points improvement on each scale and according to the osteoarthritis ankle
Displaced intra-articular fractures of the calcaneus need anatomic reduction of the joint surfaces and overall shape to restore function and minimize the risk of posttraumatic subtalar arthritis. The morbidity associated with extended approaches is a major concern. In the present study we compared the medium-term results after percutaneous reduction and screw fixation (PRSF) with that of open reduction and internal fixation (ORIF) for displaced fractures with less severe fracture patterns (Sanders type II). Material and Methods: In a matched cohort study from March 1998 to October 2004 the results of 36 patients treated either with PRSF or ORIF for displaced Sanders type II calcaneal fractures and Tscherne grade 1–2 closed soft tissue injury were reviewed. Each group contained 3 female and 15 male patients. Mean patient age was 40.1 years in the PRSF and 42.6 years in the ORIF group. PRSF was carried out percutaneously with small fragment (3.5 mm) screws under arthroscopic and fluoroscopic control. ORIF was performed with a lateral plate via an extended lateral approach. Early ROM exercises of the ankle and subtalar joints were initiated for all patients at the first postoperative day. Patients were mobilized with partial weight-bearing for 6–8 weeks postoperatively in their own shoes. Detailed follow-up with clinical and radiographic evaluation was obtained for all patients at a mean of 23 months postoperatively. Results: One patient (5.6%) from the ORIF group developed postoperative wound edge necrosis that responded well to conservative management with antiseptic dressings. In the PRSF group no complications were seen. Patients fully returned to work after 10.8 weeks in the PRSF group and 16.2 weeks in the ORIF group. Subjectively 17 of 18 patients (94%) in the PRSF group and 15 of 18 patients (83%) in the ORIF group rated their result as good to excellent at follow-up. The AOFAS Ankle
Arthrodesis of both the ankle and the hindfoot has been discussed in the literature since the early part of the last century. Techniques have been modified substantially since these early discussions, though complications remain a frustrating element in patient management. Early procedures relied on molded plaster casts to hold fixation in corrected positions. Successful outcomes were hampered by loss of reduction in these casts and subsequent malunions. In addition, motion within these casts lead to a high rate of nonunion between the opposed bony surfaces. The era of internal fixation allowed compression across arthrodesis sites, enhancing union but creating a host of technical errors leading to unsatisfying results. Malunion is also seen in post-traumatic situations. In particular, non-operative management of calcaneus fracture (or other hindfoot fractures) leads to not only arthritis of the involved joint surfaces, but malunion complicating successful fusion. Fusion in-situ leads to a high level of patient dissatisfaction, leading surgeons to challenging deformity correction while trying to achieve successful arthrodesis in compromised joints. This lecture will focus on two types of malunion, one iatrogenic, one acquired. Revision triple arthrodesis (iatrogenic) can range from simple to challenging. A variety of studies document patient dissatisfaction following correction via this technique, ranging from Graves and Mann (1993) where the highest dissatisfaction rate was in highest in valgus malunion, to Sangeorzan and Hansen (1993), who found a 9% failure rate, most with varus malunion. The precarious balance required to create a plantigrade foot via triple arthrodesis with pre-existing deformity leaves even the most skilled surgeon challenged. As such, this component of the lecture will focus on recognition and correction of malunion based on a structured algorithmic approach we first presented in 1997. This algorithm is based on recognition of the apex of the deformity, and creating osteotomies to achieve balance. We reviewed 28 patients who returned for follow-up examination who received treatment through this algorithm and found a statistically significant improvement in pre- and postoperative AOFAS ankle/
Introduction Talar dome lesions are a common accompaniment of ankle injury resulting in ongoing symptoms and functional disability with current management resulting in fibrocartilaginous repair and failure to reconstitute the articular surface. In this study, the application of autologous chondrocyte implantation (ACI) for talar dome lesions was evaluated. Methods Between August 2001 and February 2003, eight patients with osteochondral lesions of the talus were treated with ACI. All patients underwent initial arthroscopy to harvest healthy chondrocytes for cultivation. Cells were re-implanted after three to four weeks, with a medial or lateral malleolar osteotomy using a periosteal patch harvested from the distal tibia. Post-operatively, early ankle motion was allowed but non-weight bearing advised until union of osteotomy. Clinical assessment was pre-operatively and at three, six, nine, and 12 months post-operatively. Second-look arthroscopy with biopsy for histological examination was performed at removal of internal fixation. Four males and four females with a mean age of 40 years (range 22 to 59) are presented. Pre and postoperative clinical evaluation was done using the American Orthopaedic Foot and Ankle Society
Introduction: The Ponseti method has been adopted by many pediatric orthopaedic centers throughout Europe in the last years. The minimal invasive approach and the short duration of the active treatment phase have been the main reasons to change to the Ponseti method at our institution. We report the short term results of patients treated with the Ponseti method for idiopathic clubfeet and discuss experiences and pitfalls. Material and Methods: From the end of 2002 on we have applied the treatment regime strictly as described by Ponseti himself. For this study we analyzed a group of patients comprising all patients treated for congenital idiopathic clubfoot according to the Ponseti protocol within the first three weeks after births. The need for open release surgery was the main outcome measurement in this group. Results: Between December 2002 and July 2004 we treated a total of 59 clubfeet in 37 patients with the Ponseti method. Our patient population consisted of 14 female and 23 male patients. The mean Dimeglio score was 9.2 points (5–15 points). Using the Pirani score the mean midfoot score was 1.7 points (1–3 points), the mean
The aim is to review the functional results of reconstruction of neglected Achilles Tendon Ruptures, in which the gap between the ruptured ends was a minimum of 6 cm. All ruptures had a gap of 6–8cm, intraoperatively, between the ruptured ends when the foot was put into plantigrade. There are 9 patients in our case series, who presented with neglected Achilles Tendon ruptures over a six year period. All reconstructions were done by a single surgeon. All patients had a a reconstruction done using 2 strips of gastrocnemius aponeurosis turned down to bridge the gap, with the foot in plantigrade and augmented with flexor hallucis longus. The flexor hallucis longus was threaded through the distal stump and tenodesed and myodesed to the reconstructed Achilles tendon. All patients were put in a non-weight bearing cast for 6 weeks followed by partial weight bearing, physiotherapy and strengthening exercises. There were no complications in our series. Six patients were available for assessment. At minimum of 2 years, AOFAS Score is 94.2, Ankle
Aim: To determine the value of the Pirani clubfoot-scoring system at initial presentation in predicting subsequent relapse. Method: All clubfoot patients treated by one surgeon from 2002 to 2006 were included. Treatment followed the standard protocol, involving weekly stretching and casting until the foot was corrected, followed by Achilles tenotomy and plasters for 3 weeks. Thereafter, the child was placed in a foot abduction splint. Relapses within 6 months of instigating the foot abduction splint were classed as early and subsequent relapses as late. The severity of clubfoot was assessed using the Pirani scoring system which comprises two sub-scores – Midfoot Contracture Score (MFCS) and
Introduction: Determination of the origin of chronic foot pain in osteoarthritis (OA) is challenging since clinical examination of the foot faces a complex anatomy with several joints, osseous, and non-osseous structures contributing to the symptoms. Non-invasive imaging methods (Rx, CT, MRI) show a poor correlation with pain degree. Studies using functional imaging based on the detection of activated osteoblasts with 99mTc-Dicarboxypropandiphosphate (DPD) to indicate painful facet joints show promising results, but so far no evaluation for chronic OA pain conditions in foot joints has been conducted and the diagnostic potential was limited due to poor spatial resolution of the scintigraphic assessment. Single Photon Emission Computed Tomography – Computed Tomography (SPECT-CT) combines metabolic information with an exact anatomical localization. We hypothesised that diagnostic infiltration with a local anaesthetic of a painful hindfoot or midfoot joint showing 99mTc-DPD-uptake in SPECT-CT, leads to a positive OA pain response. Methods: 26 patients with chronic OA pain and radiological signs of OA in a hindfoot or midfoot joint (27 feet) were included. Plain radiography was performed to detect degenerative changes and to rule out pathologies different from OA. Pain status was measured by Visual Analogue Scale (VAS). AOFAS
Purpose: Osteoarthritis (OA) is a common disease with increasing prevalence and rising socioeconomic burden. Of all symptoms accompanying OA, pain is the most disabling and frequent and the major reason why patients affected seek medical help. The determination of the origin of chronic foot OA pain is challenging since clinical examination of the foot faces a complex anatomy with several joints, osseous, and non-osseous structures contributing to the symptoms. For OA non-invasive imaging methods like plain radiograph, CT or MRI underestimate the degree of degenerative changes and show a poor correlation with pain degree. Studies using functional imaging based on the detection of activated osteoblasts with 99mTc-Dicarboxypropandiphosphate (DPD) to indicate painful facet joints in the lower spine show promising results, but so far no evaluation for chronic OA pain conditions in foot joints has been conducted and the diagnostic potential was limited due to poor spatial resolution of the scintigraphic assessment. Single Photon Emission Computed Tomography – Computed Tomography (SPECT-CT) is a new hybrid technique combining metabolic information with an exact anatomical localization. We hypothesised that diagnostic infiltration with a local anaesthetic of a painful hindfoot or midfoot joint showing 99mTc-DPD-uptake in SPECT-CT, leads to a positive OA pain response. Method: 26 patients with chronic OA pain and radiological signs of OA in a hindfoot or midfoot joint (27 feet) were included. Plain radiography was performed to detect degenerative changes and to rule out pathologies different from OA. Pain status was measured by Visual Analogue Scale (VAS). AOFAS
Flexor hallucis longus (FHL) tendon transfer is a well-recognized
technique in the treatment of the neglected tendo Achillis (TA)
rupture. We report a retrospective review of 20/32 patients who had undergone
transtendinous FHL transfer between 2003 and 2011 for chronic TA
rupture. Their mean age at the time of surgery was 53 years (22
to 83). The mean time from rupture to surgery was seven months (1
to 36). The mean postoperative follow-up was 73 months (29 to 120).
Six patients experienced postoperative wound complications.Aims
Patients and Methods
To assess the effect of high tibial and distal femoral osteotomies
(HTO and DFO) on the pressure characteristics of the ankle joint. Varus and valgus malalignment of the knee was simulated in human
cadaver full-length legs. Testing included four measurements: baseline
malalignment, 5° and 10° re-aligning osteotomy, and control baseline
malalignment. For HTO, testing was rerun with the subtalar joint
fixed. In order to represent half body weight, a 300 N force was applied
onto the femoral head. Intra-articular sensors captured ankle pressure.Aims
