The Lisfranc fracture dislocation of the tarsometatarsal joint (TMTJ) is a complex injury with a reported incidence of 9.2 to 14/100,000 person-years. Lisfranc fixation involves dorsal bridge plating, transarticular screws, combination or primary arthrodesis. We aimed to identify predictors of poor patient reported outcome measures at long term follow up after operative intervention. 127 patients underwent Lisfranc fixation at our Level One Trauma Centre between November 2007 and July 2013. At mean follow-up of 10.7 years (8.0-13.9), 85 patients (66.92%) were successfully contacted. Epidemiological data including age, gender and mechanism of injury and fracture characteristics such as number of columns injured, direction of subluxation/dislocation and classification based on those proposed by Hardcastle and Lau were recorded. Descriptive analysis was performed to compare our primary outcomes (AOFAS and FFI scores). Univariate analysis and multivariate regression analysis was done adjusted for age and sex to compare the entirety of our data set. P<0.05 was considered significant. The primary outcomes were the American Orthopaedic Foot and Ankle Society (AOFAS) Midfoot Score and the Foot Function Index (FFI). The number of columns involved in the injury best predicts functional outcomes (FFI, P <0.05, AOFAS, P<0.05) with more columns involved resulting in poorer outcomes. Functional outcomes were not significantly associated with any of the fixation groups (FFI, P = 0.21, AOFAS, P = 0.14). Injury type by Myerson classification systems (FFI, P = 0.17, AOFAS, P = 0.58) or open versus closed status (FFI, P = 0.29, AOFAS, P = 0.20) was also not significantly associated with any fixation group. We concluded that 10 years post-surgery, patients generally had a good functional outcome with minimal complications. Prognosis of functional outcomes is based on number of columns involved and injured. Sagittal plane disruption, mechanism and fracture type does not seem to make a difference in outcomes

Despite the current trend favoring surgical treatment of displaced intra-articular calcaneal fractures (DIACFs), studies have not been able to demonstrate superior functional outcomes when compared to non-operative treatment. These fractures are notoriously difficult to reduce. Studies investigating surgical fixation often lack information about the quality of reduction even though it may play an important role in the success of this procedure. We wanted to establish if, amongst surgically treated DIACF, an anatomic reduction led to improved functional outcomes at 12 months. From July 2011 to December 2020, at a level I trauma center, 84 patients with an isolated DIACF scheduled for surgical fixation with plate and screws using a lateral extensile approach were enrolled in this prospective cohort study and followed over a 12-month period. Post-operative computed tomography (CT) imaging of bilateral feet was obtained to assess surgical reduction using a combination of pre-determined parameters: Böhler's angle, calcaneal height, congruence and articular step-off of the posterior facet and calcaneocuboid (CC) joint. Reduction was judged anatomic when Böhler's angle and calcaneal height were within 20% of the contralateral foot while the posterior facet and CC joint had to be congruent with a step-off less than 2 mm. Several functional scores related to foot and ankle pathology were used to evaluate functional outcomes (American Orthopedic Foot and Ankle Score - AOFAS, Lower Extremity Functional Score - LEFS, Olerud and Molander Ankle Score - OMAS, Calcaneal Functional Scoring System - CFSS, Visual Analog Scale for pain - VAS) and were compared between anatomic and nonanatomic DIAFCs using Student's t-test. Demographic data and information about injury severity were collected for each patient. Among the 84 enrolled patients, 6 were excluded while 11 were lost to follow-up. Thirty-nine patients had a nonanatomic reduction while 35 patients had an anatomic reduction (47%). Baseline characteristics were similar in both groups. When we compared the injury severity as defined by the Sanders’ Classification, we did not find a significant difference. In other words, the nonanatomic group did not have a greater proportion of complex fractures. Anatomically reduced DIACFs showed significantly superior results at 12 months for all but one scoring system (mean difference at 12 months: AOFAS 3.97, p = 0.12; LEFS 7.46, p = 0.003; OMAS 13.6, p = 0.002, CFSS 7.5, p = 0.037; VAS −1.53, p = 0.005). Univariate analyses did not show that smoking status, worker's compensation or body mass index were associated with functional outcomes. Moreover, fracture severity could not predict functional outcomes at 12 months. This study showed superior functional outcomes in patients with a DIACF when an anatomic reduction is achieved regardless of the injury severity

Introduction. By utilising the inherent variability achievable with circular frames, surgeons can manage a wide spectrum of complex injuries, and can deal with deformity at multiple levels, in multiple planes. The aim of this study was to assess functional outcomes utilising patients reported outcome measures (PROMs) of patients being treated with circular (Ilizarov) frame fixation for complex lower limb injuries and assess these results in conjunction with the observed postoperative alignment of the patients’ limbs. Materials & Methods. Cases were identified using a prospectively collected database of adult patients presenting between July 2018 and August 2021. Functional outcomes were assessed using the American Orthopaedic Foot and Ankle Score (AOFAS), the 5-level EQ-5D (EQ5D5L), the Lysholm Knee Scoring Scale (LKSS), the Olerud-Molendar Ankle Score (OMAS), and the Tegner Activity Scale (TAS). Postoperative radiographs were analysed for fracture union and to quantify malunion (as described in Dror Paleys Principles of Deformity Correction). Results. The mean AOFAS, EQ5D5L, LKSS and OMAS scores showed an initial drop from pre-op to early time points and then steady increase over the early, mid, late and frame-off time points, with a resultant score higher than pre-op. Malunion was found in 35 (41.7%) patients, 7 patients had a malunion within 5 degrees of normal, 15 from 5–10 degrees of normal, 12 from 10–15 degrees of normal and 2 out with 15 degrees of normal. Conclusions. Circular frame fixation is an attractive option in complex lower limb trauma where alternative fixation methods are unsuitable. Whilst post-operative success to the surgeon might be determined radiographically, patient reported outcomes give a functionally important, objective measure of the success of the surgery to the patient

Reported wound complication in below knee surgery can be quite high. Recent study demonstrated that increased blood loss and hematoma formation increase wound complications especially in foot and ankle surgeries. Despite the evidence on the benefit of TXA on blood loss in TKA and THA it is not routinely used by surgeon in below knee surgery. To assess the efficacy and safety of this medication in reducing wound complication and blood loss and the risk of thromboembolic complications in patients undergoing below knee surgery. A systematic literature search of PubMed, Embase, Ovid, the Cochrane Library and AAOS and AOFAS conference proceedings was conducted. The primary outcome was the rate of wound complications. Data were analyzed using the Review Manager 5.3 software. Nine studies involving 861 patients met the inclusion criteria. The meta-analysis indicated that TXA, when compared to a control group, reduced wound complications (OR, 0.54; 95% IC, 0.31 to 0.95, p = 0,03), blood loss (MD = −149,4 ml; 95% CI, −205,3ml to −93,6ml), post-operative drainage (MD = −169,8 ml; 95% CI, −176,7 to −162,9 ml) and hemoglobin drop (MD = −8,75 g/dL; 95% IC, −9,6 g/dL to −7,8 g/dL). There was no significant difference in thromboembolic events (RR 0,53; 95% CI, 0,15 - 1,90; p = 0,33). This study demonstrated that TXA could be use in below knee surgery to reduce wound complication and blood loss without increased thromboembolic complications. The small number of studies limit the findings interpretation. Further studies are needed to sustain those resutls

Tibiotalocalcaneal arthrodesis (TTCA) is a salvage procedure to functionally block the ankle and subtalar joints to treat severe ankle and hindfoot disease. Complication rates range between 20-40%, with below-knee amputation rate 1.5-19%. The heterogeneous patient cohort and indication(s) for surgery make post-operative outcomes difficult to predict. Consulting patients about potential pain and functional outcomes is difficult. When researching this area commonly, PROM data is used, less frequently functional objective measures like the 2-minute-walk-test (2MWT) are used. The aim was to compare the PROMs and objective outcomes between patients who underwent TTCA and BKA. Fifty-two patients underwent a TTCA using an intramedullary hindfoot nail. Indications for TTCA, post-traumatic OA, failed arthrodesis and malalignment. These patients were compared to 11 patients who underwent unilateral below knee amputation (BKA) due to trauma. Outcomes measures PROMs AOFAS ankle hindfoot scale and Shor-Form 36 (SF-36). Objective measures; 2MWT, Timed-up-and-go (TUG). Mean age TTCA 55.9, BKA 46.4. Average follow-up time 53 months. TTCA group had average 6.3 operations prior to arthrodesis (range 1-23). Of the TTCA group two ankles did not unite (7%), all complication rate 35%, 18% reported no pain. A significant negative correlation was demonstrated between the clinical outcome and the number of surgeries prior to the TTCA. TUG and 2MWT had significantly (p<0.05) better outcomes for the BKA group compared to TTCA. SF-36 BKA patients scored higher than the TTCA patients on physical functioning (p<0.01) and mental health (p<0.05) subscales as well as the mental component score (p<0.05). This study gives clinicians evidence about the natural history of hindfoot arthrodesis and functional outcomes from BKA. Hopefully this study will improve evidence to help patients and surgeons make decisions about expected surgical outcomes from TTCA and BKA procedures

Researchers and clinicians measuring outcomes following total ankle replacement (TAR) are challenged by the wide range of outcome measures used in the literature without consensus as to which are valid, reliable, and responsive in this population. This review identifies region- or joint-specific outcome measures used for evaluating TAR outcomes and synthesises evidence for their measurement properties. A standard search strategy was conducted of electronic databases MEDLINE, EMBASE and CINAHL (to June 2015) to identify foot/ankle measures in use. A best evidence synthesis approach was taken to critically appraise measurement properties [COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN)] of identified measures. The review was restricted to English publications and excluded cross-cultural adaptations. Measurement properties collected from each article were coded for validity, reliability, responsiveness, or interpretability. Clinimetric evidence exists for identified measures tested in non-TAR populations, but were not the focus of this review. The search identified 14 studies to include in the best evidence synthesis with 32 articles providing clinimetric evidence for eight of the measures (one CBO, seven PRO), however only five measures were tested in a TAR population (Foot Function Index, Ankle Osteoarthritis Scale, American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale [AOFAS], Foot and Ankle Outcome Score, Self-Reported Foot and Ankle Score). Five studies provided clinimetric evidence in a TAR population and their methodological quality was assessed: (1) Validity—two good quality studies examining different measures provide moderate evidence supporting construct validity (FFI, AOS, AOFAS self-reported items; SEFAS); (2) Reliability—two good quality studies examining different measures provide moderate evidence supporting internal consistency and test-retest reliability (FFI, AOS, AOFAS self-reported items; FAOS, SEFAS); (3) Responsiveness—three poor quality studies, thus unknown evidence for responsiveness; (4) Interpretability—two studies provide interpretability values (AOS, FFI, AOFAS self-reported items; AOS). This review offers a basis for choosing the most appropriate instrument for evaluating TAR outcomes. Numerous outcome measures were identified with evidence supporting their use in populations with various foot/ankle conditions, but none have strong evidence supporting use in a TAR population. Measures must have adequate clinimetric properties in all patient groups in which they are applied. Evidence supporting or critiquing an instrument should not be based on studies with poor quality methodology, as identified by this review. Further testing in a TAR population would benefit identified measures with emphasis on adequate sample sizes, testing a priori hypotheses, and evaluating their content validity for a TAR population

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 hindfoot scores from 34.37 to 71.33 (p=0.00). There was a significant decrease in SF-36 for bodily pain, and significant increases in physical and social function scores. Twelve out of 14 (85.7%) patients reported ‘good’ to ‘excellent’ satisfaction results at six months, and 11 out of 14 (78.6%) patients had their expectations met from the procedure at six months follow-up. TOPAZ RF coblation is a good and effective method for the treatment of plantar fasciitis. Early results are encouraging, and we believe that the pain experienced by the patients in the follow-ups will subsequently improve

Purpose. Osteochondral lesions (OCL) of the talus remain a challenging therapeutic task to orthopaedic surgeons. Several operative techniques are available for treatment, e.g. autologous chondrocyte implantation (ACI), osteochondral autograft transfer system (OATS), matrix-induced autologous chondrocyte implantation (MACI). Good early results are reported; however, disadvantages are sacrifice of healthy cartilage of another joint or necessity of a two-stage procedure. This case describes a novel, one-step operative treatment of OCL of the talus utilizing the autologous matrix-induced chondrogenesis (AMIC) technique in combination with a collagen I/III membrane. Method. 20 patients (8 female, 12 male; mean age 36, range 17–55 years) were assessed in our outpatient clinic for unilateral OCL of the talus. Preoperative assessment included the AOFAS hindfoot scale, conventional radiography, magnetresonancetomography (MRI) and SPECT-CT. Surgical procedure consisted of debridement of the OCL, spongiosa plasty from the iliac crest and coverage with the I/III collagen membrane (Chondrogide, Geistlich Biomaterials, Wolhusen, Switzerland). Clinical and radiological followup was performed after one year. Results. The mean preoperative AOFAS hindfoot scale was poor with 63.1 points (SD 19.6). At one year followup the score improved significantly (p<0.01) to 86 points (SD 12). At one year followup conventional radiographs showed osseous integration of the graft in all cases. MRI at one year showed intact cartilage covering the lesions in all cases. Conclusion. The initial results of this ongoing study are encouraging. The clinical and radiological results at one year followup are comparable with the results of ACI, OATS and MACI. The AMIC procedure is a readily available, economically efficient, one step surgical procedure. No culturing after chondrocyte harvesting or destruction of viable cartilage is necessary

The Mobility (DePuy International) is a three-component, cobalt chrome, uncemented design. Patients. Over an 18-month period 100 ankles, with end-stage arthritis and less than 20 degree valgus or varus deformity, were replaced. There were 95 patients (70 OA, 25 RA) with average age of 65 years (41-95). Five had bilateral replacements. Follow-up was 30 months (24 to 48). Results. Average score on VAS pain line improved from 8.8 to 1.8. The average AOFAS pain score improved from 3 to 33. Average AOFAS function score improved from 31 to 48. Four patients were disappointed because pain relief was poor. Four ankles have undergone further surgery. One ankle was converted to fusion for recurrent deformity. One ankle required repeated washout for infection at six months but remains clinically and radiologically satisfactory 2 years later. One ankle required exchange of UHMWP insert at 4 weeks because of a technical error. One ankle required fixation of an ununited intraoperative medial malleolar fracture and subsequently developed ‘edge loading’, namely radiographs showed that a gap had opened up between the articular surfaces on the lateral side of the joint. The radiographs of 3 other ankles also showed ‘edge loading’. Two of these patients were symptom free but one wore a brace to control symptoms of instability. Radiographs showed bony incorporation in all surviving ankles. This was always complete around the tibial stem and under the talar component. However in 15 ankles there was a small non-progressive area of lucency adjacent to the tibial plate. Conclusion. These early results are encouraging and an improvement on those previously reported by the same surgeon using other designs. We believe that this is attributable to the ongoing process of refining the indications and improving surgical technique and implant design

Purpose. The objective of this study was to compare items from musculoskeletal outcome questionnaires with items generated by pre- and post-operative ankle arthrodesis and arthroplasty patients (patient-selected portion of the Patient-Specific Index (PASI-P)) to determine if existing questionnaires address patients' concerns. Materials/Methods. Patients (n=142) completed the PASI-P. Items from 6 standardised questionnaires (AAOS, patient-reported portion of AOFAS, FFI, LEFS, SMFA, WOMAC) and PASI-P were matched by 3 reviewers to corresponding categories in the International Classification of Functioning, Disability and Health (ICF). The ICF classification hierarchy codes broad first categories and increasingly detailed second, third, and fourth categories. The standardised questionnaires were then compared to the ‘gold standard’ of PASI-P. Results. 690 concepts were identified in the patients' responses, which corresponded to 45 ICF categories. Most PASI-P concepts fell into Activities and Participation (60.3%) and Body Functions and Body Structures (35.2%), including the second level categories ‘walking’ (21.6%), ‘pain’ (18.7%), and ‘recreation and leisure’ (17.4%). A total of 237 concepts was identified in the 6 questionnaires and linked to 39 second level ICF categories. Overall, SMFA addressed the most second level categories and had the closest proportion of Activities and Participation (68.9%) and Body Functions (23.0%) concepts compared to the patient-generated responses. The patient-reported portion of AOFAS addressed the fewest categories. LEFS only contained items from Activities and Participation. AAOS was the only questionnaire to address the issue of ‘swelling’, though it represented 5.6% of all patient-generated responses. The concepts of ‘swelling’, ‘recreation and leisure’, and ‘sports’ were seldom included in the questionnaires. Conclusion. No single questionnaire captured all concerns identified by patients, and the standardised questionnaires differed largely in content. Clinicians should recognise patient concerns relevant to the ankle currently not included in available questionnaires. This analysis will guide the development of a more comprehensive instrument for evaluating ankle outcomes

Tibiotalocalcaneal arthrodeisis is performed for a variety of conditions, including advanced osteoarthritis, Charcot arthropathy, rheumatoid arthritis, post-traumatic arthrosis and foot deformities such as fixed equinovarus. There have been few published studies showing the results of such a procedure for limb salvage. Over a period of 11 years between 1996 and 2007, 18 patients underwent calcaneotalotibial arthrodeisis using either cannulated screws or a retrograde intramedullary locking nail. Post-operative rehabilitation regimes were standardised. VAS, AOFAS ankle-hindfoot, SF-36 and patient satisfaction scores were obtained and analysed. Eighteen patients (10 male and 8 female) with 19 ankles underwent tibiotalocalcaneal arthrodeisis at an average age of 52.3 (31.4 to 70.2 years). Seven patients had cavovarus deformity, six had osteoarthritis, three had Charcot's joint, two had failed previous fusions and one patient had a footdrop post-T12 tumour resection. Twelve right and seven left fusions were performed, with six cannulated screws and 13 retrograde nails. The mean time to complete fusion was 5.89 (3 to 11) months in 18 ankles (94.7%). There was one pseudoarthrosis (5.3%). Patients were followed up for an average of 35.6 (11 to 144) months. Four wound infections (21%) occurred post-operatively. Two patients died from unrelated caused whilst on follow-up. Thriteen patients returned for follow-up scoring. VAS scores improved from 7.85 to 2.54 (p=0.00). AOFAS ankle-hindfoot scores improved from 30.50 to 63.62 (p=0.00). SF-36 scores also improved in several parameters. Physical function improved from 40.38 to 66.15 (p=0.02); physical role improved from 15.38 to 53.85 (p=0.03); Bodily pain improved from 36.69 to 62.23 (p=0.00); emotional role improved from 69.23 to 100 (p=0.04); and mental health improved from 62.77 to 0.15 (p=0.04). Eleven patients (84.6%) reported good to excellent satisfaction and expectation scores. Hindfoot arthrodesis, via retrograde imtramedullary nailing or cannulated screw insertion, are effective techniques for treating complex foot deformities and often is the only alternative to amputation. Although a demanding procedure with high potential complications, they provide effective relief from pain, improves the quality of life, and has high patient satisfaction

Purpose. Coronal plane malalignment at the level of the tibiotalar joint is not uncommon in advanced ankle joint arthritis. It has been stated that preoperative varus or valgus deformity beyond 15 degrees is a relative contraindication and deformity beyond 20 degrees is an absolute contraindication to ankle joint replacement. There is limited evidence in the current literature to support these figures. The current study is a prospective clinical and radiographic comparative study between patients who underwent total ankle arthroplasty with coronal plane varus tibiotalar deformities greater than 10 degrees and patients with neutral alignment, less than 10 degrees of deformity. Method. Thirty-six ankles with greater than 10 degrees of varus alignment were compared to thirty-six ankles which were matched for implant type, age, gender, and year of surgery. Patients completed preoperative and yearly postoperative functional outcome scores including the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scores, the Ankle Osteoarthritis Scale (AOS) and the Short Form-36 Standard Version 2.0 Health Survey. Weightbearing preoperative and postoperative radiographs were obtained and reviewed by four examiners (AC, AQ, TD, TT) and measurements were taken of the degree of coronal plane deformity. Results. After a mean follow-up of 27 months (9–54), the varus ankles improved significantly on the AOFAS (P<0.0001), AOS-Pain Score (P<0.0001), AOS-Disability Score (P<0.0001), and SF-36 Physical Component Score (P<0.0001). There was no improvement in SF-36-Mental Component Score. (P=0.722). There was no statistically significant differences between the two groups when comparing AOFAS (P=0.155), AOS-Pain Score (P=0.854), AOSDisability Score (P=0.593), SF-36-Physical Component Score (P=0.433), SF-36 Mental Component Score (P=0.633). Sixteen of Thirty-Six ankles in the varus group needed a secondary procedure (implant failure, infection, malalignment) which was approaching significance in comparison to eight ankles in the neutral group. (P = 0.079). Secondary procedures in the varus group included: tendon transfers, calcaneal / metatarsal / malleolar ostoetomies and ligament reconstructions. Radiographically, the pre-operative coronal plane varus tibiotalar deformity averaged 19.4 6.4 and postoperatively 1.44 2.6 (P< 0.0001). There was no statistical difference in post operative tibiotalar alignment between the varus and neutral groups (P<0.05). Conclusion. The clinical outcome of TAR performed in ankles with pre-operative varus alignment >10 degrees is comparable with that of neutrally aligned ankles. The increased number of secondary procedures in the varus group was attributed to the complexity of the deformity and the steep learning curve. Outcomes as measured radiographically and through validate scores were similar to patients without deformity suggesting that varus coronal plane deformity of the talus is not a contraindication to total ankle replacement

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 hindfoot score. Radiological assessment was performed from weight-bearing radiographs, documenting post-operative alignment, osseous integration, edge-loading and heterotopic bone formation. The mean follow-up time was 40 months (Range 30–60). Survival analysis was calculated according to the Kaplan-Meier method. Failure was defined as exchange of any component of the TAR, arthrodesis or amputation. Results. Type 1 ankle arthritis was demonstrated in 54 ankles (63%). No patient had pre-operative coronal plane angulation > 20. In 30 ankles (35%), the pre-operative coronal alignment was neutral, and in 32 ankles (37%), the deformity was < 10. The mean AOFAS hindfoot score improved from 37.4 (Range 12–59) pre-operatively to 77.9 (Range 51–100) post-operatively. 78 (90%) of prosthetic components were implanted within 5 of the optimal position. Bone-implant interface abnormalities were identified in 16 ankles (18%). In total, 5 TARs required revision, 4 for aseptic loosening and one for component malpositioning. There was one conversion to arthrodesis, and one BKA for CRPS. 30 simultaneous procedures were performed in 28 patients. The most common was gastrocnemius recession. There were 8 re-operations, most commonly for impingement due to peri-articular ossifications. Delayed wound healing occurred in 3 patients, and there was one case of deep infection. There were 5 patients that sustained fractures of the medial malleolus: 2 were intra-operative, and underwent internal fixation. There are 6 patients being investigated for ongoing pain. The 2-year survival was 96.4% (95% CI 89.4–99.1) and 3-year survival was 91.7% (95% CI 83.3–96.3). Conclusion. Although early results of the Mobility TAR are encouraging for independent researchers, they do not match those reported by designer surgeons. Most patients achieve good pain relief and improved function post-operatively

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. Results. The AOFAS hindfoot score improved from 46.4 to 89.5 (max.: 100) points 1 year postoperatively und decreased to 87.8 points at the last follow-up. VAS for pain decreased from 6.6 to 1.1 at the one year follow-up and increased to 1.5 at the last follow-up. All radiologic parameters improved and stayed without significant changes over time. Following complications were seen: one recurrence, two patients with irritation of the sural nerve, one patient with hypesthesia of the big toe. In six patients the screws had to be removed. Apart from that no other revision surgery had to be done. Conclusion. Flexor digitorum longus transfer together with medializing calcaneal osteotomy provides excellent results for the therapy of acquired flat foot deformity. The results did not change significantly over time

Arthrodesis of the first metatarsophalangeal joint (MTPJ) has been reported as gold standard for the treatment of advanced hallux rigidus and is a well-documented procedure. However, many patients demand a mobile MTPJ and therefore joint sparing procedures like MTPJ-arthroplasty have gained popularity. The aim of the present study was to present first mid-term results after hemiarthroplasty to treat advanced osteoarthritis of the first MTPJ. Between April 2006 and October 2013, a total of 81 hemiprostheses (AnaToemic®, Arthrex) in 71 consecutive patients (44 females, 27 male, 10 bilateral; mean age, 58 [range, 45–82]) were implanted at the St. Vincent Hospital Vienna (Austria). The indication for surgery was persistent MTPJ pain after failed conservative treatment combined with radiologic evidence of osteoarthritis (advanced hallux rigidus grade II-IV). Patients were clinically examined using the American Orthopaedic Foot and Ankle Society (AOFAS) score before surgery and at the final follow-up visit. Patient's satisfaction with the treatment was recorded. Radiological results were evaluated using standard x-rays and revision surgeries were documented. The mean preoperative AOFAS Scores significantly increased from 51 to 88 points after an average follow-up duration of 5 years (p<0.001). Most patients (76%) were either very satisfied or satisfied with the procedure. Radiological assessment showed some kind of radiolucencies on the base plate, whereas the stem of the prosthesis was well integrated in most of the cases; however clinical outcome was not affected by minor radiolucent lines on the base plate. In the majority of patients the implant was in situ at last follow-up. If revision surgery, due postoperative pain or implant loosening, was required; it occurred within 12 to 36 months. According to our promising mid-term results with a MTPJ-hemiprostheses, we conclude that MTPJ-arthroplasty is an effective alternative treatment modality for anatomical reconstruction of the first MTPJ with the benefit to reduce pain and maintain mobility

Hallux valgus is a common condition often leading to significant symptoms. However, its correction has recently been suggested, to be a procedure of limited clinical value. Scarf osteotomy is one of the most commonly performed operations for hallux valgus correction. Although technically demanding, it is powerful in its capacity to correct the hallux valgus deformity and sufficiently robust with internal fixation to allow early weight bearing. We prospectively collected data for consecutive scarf osteotomies between 2008 and 2011. Preoperative and 6 week postoperative assessment was made using radiographic measurements HVA (hallux-valgus angle) and IMA (inter metatarsal angle). We evaluated 130 scarf osteotomies. The mean HVA improved from 29.5 pre-operatively to 12.6 post correction. The mean IMA improved from 12.4 pre-operatively to 8.1 post correction. The AOFAS hallux scores improved from an average of 55 pre op to 79 post operation. The results suggest that hallux valgus correction does have clinical value and that scarf osteotomy is a reproducible procedure, with a generally good to excellent results in the short term

Aim:. To review the short to medium term radiological, clinical and functional outcomes of reconstructive surgery for severe forefoot deformities in patients with Rheumatoid arthritis. Methods:. We conducted a review of prospectively collected data of patients with Rheumatoid arthritis who received reconstructive surgery for forefoot deformities. Patients requiring metatarso-phalangeal joint arthrodesis and excision of the lesser metatarsals for hallux valgus, dislocation of the lesser metatarso-phalangeal joints and intractable plantar keratosis were included. The patients were followed up at 2 weeks, 6 weeks, 3 months and 6 months. X-Rays were performed preoperatively, postoperatively, at 6 weeks, 3 months and 6 months follow-up. Patients completed a SF36, and AOFAS (American Orthopaedic Foot and ankle Score) forefoot score preoperatively and at 6 months postoperatively. Results:. Ten feet in eight patients were included in the study. Follow-up was for a minimum of 6 months. All patients were female, with an average age of 58 years (34–69 years). Radiologically there was an average correction in the hallux valgus angle from 48 degrees to 15 degrees. The inter-metatarsal angle improved from 14 to 9 degrees. Objective scores were significantly improved. The mean SF36 score pre-operatively was 36 (24–54) and 67 (54–82) post operatively (P < 0.05). The AOFAS score improved from a mean of 32 (28–50) pre operatively to 74 (64–78) post-operatively (p < 0.05). One patient required re-operation for further metatarsal shortening due to ongoing pain and two patients required oral antibiotics for minor superficial wound infections. All hallux metatarsophalangeal joint arthrodesis procedures united in a mean time of 3.5 months. Conclusion:. Forefoot reconstruction in these very symptomatic, disabled patients resulted in significant deformity correction and improvement in function and pain. The complication rate was low. Adequate resection of the lesser metatarsals is necessary to avoid ongoing pain from the phalanx articulating with the metatarsal

Introduction. Total Ankle replacement designs continue to evolve, and provide an alternative to ankle arthrodesis for patients with ankle arthritis. It has been our practice to offer total ankle replacement to selected patients with ankle arthritis. The purpose of this study was to analyse the short term results of our patients with the Mobility R Total Ankle Replacement (TAR) system. Methods. All patients who received TAR in our practice from 2004 to 2011 were reviewed. American Orthopaedic Foot and Ankle Scores AOFAS were assessed and compared both preoperatively and at time of follow-up. All complications both intra-operative and post-operatively were noted. Weight bearing X-rays were taken at follow-up, and implant alignment and the presence of lucencies were noted. Results. 21 patients were evaluated. All showed an improvement in AOFAS scores; however the improvement showed a wide variation. All patients showed an improvement in pain scores. Post-operative ankle stiffness, specifically dorsi-flexion, was problematic in several patients. Marked prolonged swelling was problematic for many patients. Conclusions. Total ankle replacement provides a good option for patients with ankle arthritis. Swelling and post-operative stiffness continue to be a problem, and should be explained to patients. MULTIPLE DISCLOSURES

The purpose of this study is to assess the improvement in pain and function of the ankle when arthrodiastasis is used for end stage juvenile idiopathic arthritis [JIA] in the paediatric population. All patients treated with ankle arthrodiastasis, 2009–2013 were studied. Clinical, radiological and survivorship data were examined. The Oxford Ankle Foot Questionnaire for Children (OxAFQ-C) and Parents (OxAFQ-P), along with the American Orthopaedic Foot and Ankle Society (AOFAS) Clinical rating system for Ankle-Hindfoot were recorded pre-operatively and at 6 months. Eight patients (9 ankles) with severe tibiotalar JIA, refractory to medical management were treated. Average age at surgery was 14.5 years (range 8–19). Average length of arthrodiastasis was 3.5 months. Length of follow-up averaged 13 months (range 5–28 months). All scores showed an improvement at 6 months. OxAFQ-C scores (out of 60) improved on average from 23 to 43. OxAFQ-P scores also improved from19 to 39. The largest improvement was found for the physical subsection. AOFAS Ankle-Hindfoot score (out of 100) averaged 34 pre-op and 74 at 6 months. Pain scored out of 10 decreased from an average of 7.4 to 4.3 at 6 months. All patients and parents were satisfied with the surgery and would have the procedure performed again. Radiological studies demonstrated cartilage regeneration, joint restoration and deformity correction with arthrodiastasis. Survivorship was good (75%) at 36 months, but 2 patients (3 ankles) had subsequent surgery in the adult sector for progression of disease despite initial improvement following arthrodiastasis. This case series demonstrates the efficacy of ankle arthrodiastasis as a surgical option in severe end-stage ankle inflammatory arthritis in paediatric patients in the short to midterm. It improved functional scores and pain scores which should delay the need for more radical joint fusion or replacement procedures in this challenging surgical condition
