Despite advancements, revision rates following total ankle replacement (TAR) are high in comparison to other total joint replacements. This explant analysis study aimed to investigate whether there was appreciable metal particulate debris release from various contemporary TARs by describing patterns of material loss. Twenty-eight explanted TARs (9 designs: 3 fixed and 6 mobile bearing), revised for any reason, were studied. The articulating surfaces of the metal tibial and talar components as well as the polyethylene insert were assessed for damage features using light microscopy. Based on the results of the microscopic analysis, scanning electron microscopy with energy dispersive X-ray spectroscopy was performed to determine the composition of embedded debris identified, as well as non-contacting 3D profilometry. Pitting, indicative of material loss, was identified on the articulating surfaces of 54% of tibial components and 96% of talar components. Bearing constraint was not found to be a factor, with similar proportions of fixed and mobile bearing metal components showing pitting. More cobalt-chromium than titanium alloy tibial components exhibited pitting (63% versus 20%). Significantly higher average surface roughness (Sa) values were measured for pitted areas in comparison to unpitted areas of these metal components (p<0.05). Additionally, metallic embedded debris (cobalt-chromium likely due to pitting of the tibial and talar components or titanium likely from loss of their porous coatings) was identified in 18% of polyethylene inserts. The presence of hard 3. rd. body particles was also indicated by macroscopically visible sliding plane scratching, identified on 79% of talar components. This explant analysis study demonstrates that metal debris is released from the articulating surfaces and the coatings of various contemporary TARs, both fixed and mobile bearing. These findings suggest that metal debris release in TARs may be an under-recognised issue that should be considered in the study of painful or failed TAR moving forwards

We describe the surgical technique and results of arthroscopic subtalar release in 17 patients (17 feet) with painful subtalar stiffness following an intra-articular calcaneal fracture of Sanders’ type II or III. The mean duration from injury to arthroscopic release was 11.3 months (6.4 to 36) and the mean follow-up after release was 16.8 months (12 to 25). The patient was positioned laterally and three arthroscopic portals were placed anterolaterally, centrally and posterolaterally. The sinus tarsi and lateral gutter were debrided of fibrous tissue and the posterior talocalcaneal facet was released. In all, six patients were very satisfied, eight were satisfied and three were dissatisfied with their results. The mean American Orthopaedic Foot and Ankle Society ankle-hindfoot score improved from a mean of 49.4 points (35 to 66) pre-operatively to a mean of 79.6 points (51 to 95). All patients reported improvement in movement of the subtalar joint. No complications occurred following operation, but two patients subsequently required subtalar arthrodesis for continuing pain. In the majority of patients a functional improvement in hindfoot function was obtained following arthroscopic release of the subtalar joint for stiffness and pain secondary to Sanders type II and III fractures of the calcaneum

Hammer toe involves metatarsophalangeal joint (MTPJ) hyperextension and proximal interphalangeal joint (PIPJ) flexion. Surgery commonly involves excision arthroplasty or fusion of the PIPJ with MTPJ soft tissue release if necessary. Previous series record that MTPJ release was carried out “as required” but not how often release is necessary. Myerson and Shereff's (1989) cadaver study found release of the extensors, MTPJ capsule and collateral ligaments necessary for full hammertoe correction. Hossain (2002) found the clinical results of this procedure were no better than simple PIPJ fusion. We release the MTPJ if hyperextension persists after PIPJ correction and release the components sequentially. We studied how often and how extensive a release was required, and how this corelated with pre-operative assessment. We reviewed the records of 164 patients who had hammer toe correction under one consultant surgeon. Patients with complex corrections were excluded. The severity of the pre-operative deformity was classified as type 1 (PIPJ and MTPJ correctable), 2 (PIPJ fixed, MTPJ correctable) or 3 (neither joint correctable). We recorded the extent of release required for each toe. Results. Of 334 type 2 toes in 146 patients, 178 (53.3%) required no MTPJ release, 11 (3.3%) extensor tenotomy only, 15 (4.5%) extensor tenotomy and MTPJ dorsal capsulotomy and 130 (38.9%) extensor tenotomy, capsulotomy and collateral ligament release. Of 31 type 3 toes in 18 patients, one (3.2%) needed no release, 2 (6.5%) tenotomy, one (3.2%) capsulotomy and 27 (87.1%) complete release. Discussion. Nearly 50% of toes needed MTP soft tissue release, partial in 8%. Pre-operative assessment was not very accurate in predicting the need for release. We have not yet correlated need for release with clinical outcome. Conclusion. MTP release is required in many hammertoe corrections. Assessment of toe position after incision of each structure may avoid the need for complete release

Between March 1995 and January 2000 we reviewed retrospectively 84 patients with hammer-toe deformity (99 feet; 179 toes) who had undergone metatarsophalangeal soft-tissue release and proximal interphalangeal arthroplasty. The median follow-up was 28 months. Patients were assessed by the American Orthopaedic Foot and Ankle Society Scores (AOFAS) and reviewed by independent assessors.

The median AOFAS score was 83, with 87% of patients having a score of more than 60 points; 83% were satisfied and 17% were dissatisfied with the procedure. Pain at the metatarsophalangeal joint was the commonest cause of dissatisfaction, with 14% having moderate or severe pain. Only 2.5% had instability and 9% had formation of callus.

There was no statistical difference for the age and gender of the patients, the number of toes operated on, associated surgery for hallux valgus or length of follow-up. Our study was based on an anatomical model and shows good results with no recurrence of deformity.

Introduction

The mainstay of treatment in non-insertional Achilles tendinopathy is non-operative, however between 1/4 and 1/3 of patients fail this. The main symptom is pain which appears to be related to new nerve endings that grow into the tendon with the neovessels from the paratenon. Treatments which strip the paratenon from the tendon are showing promise including formal paratenon stripping via Achilles tendinoscopy. The pain and swelling in Achilles tendinopathy is usually on the medial side leading to the postulation that the plantaris tendon may have a role to play.

Methods

We report a consecutive series of 11 patients who underwent Achilles tendinoscopy with stripping of the paratenon and division of the plantaris tendon, above the level of the tendinopathic changes in the Achilles. All patients had failed conservative treatment for at least 6 months and requested surgical intervention. The patients were scored with the SF-36, AOS and AOFAS hindfoot questionnaires pre-operatively and at a minimum of 2 years post operatively. They also recorded their level of satisfaction with the treatment at final follow up.

Background. Treatment of arthrogrypotic clubfoot (AC) presents a challenging problem. Over time many different methods have been proposed, with variable rates of success, recurrence and other complications. In this study we describe our 20-year experience in treatment of AC. Materials and methods. Between 1996 and 2016, 165 AC in 90 children (51 males and 39 females) were treated in our department. Their mean age was 7.6 years (3 months-16 years). Ponseti casting and Achilles tendon release (PCATR) was performed on 38 children (68 feet) and soft tissue release and casting (STRC) on 35 children (67 feet). The remaining 17 children (30 feet) underwent wide soft tissue release and correction using the Ilizarov method (STRIL). The results of each subgroup were graded according to clinical (pain, foot appearance, residual deformities, walking and standing status and shoe modifications) and radiological (anteroposterior and lateral talocalcanear angles, the angle between longitudinal axes of talus and the first metatarsal and the position of talus in the lateral view) criteria. Results. The average follow up was 6.4 (2–10) years. Results were excellent (plantigrade, painless, properly loaded feet, without deformities, adapted to common shoes) in 56 PCATR group feet, 59 STRC group feet and 23 STRIL group feet. Good results (required orthopaedic shoes) were obtained in 10 PCATR group feet, 6 STRC group feet and 7 STRIL group feet. Fair results (residual temporary pain and/or mild deformity) presented 2 PCATR group feet and 1 STRC group foot, while bad results (reoccurrence of clubfoot) were found in 1 STRC group foot. Conclusions. On the basis of our 20-year clinical experience we believe that pediatric AC can be successfully treated with PCATR in the age of less than 1 year old (y.o), with STRC between 1–5 y.o. and with STRIL in children over the age of 5 y.o

Purpose. To explore the relationship in terms of time scale between pre-operative expectations and postoperative outcomes and satisfaction after Hallux valgus surgery. Methods. A patient derived questionnaire was developed and 30 patients aged 19 to 67 were included undergoing primary hallux valgus correction with a first metatarsal osteotomy and distal soft tissue release. Patients were asked pre-operatively to quantify their expected time scale for improvement in pain, ability to walk unaided, ability to drive, routine foot wear and foot feeling normal at 6 weeks, 3 and 6 months following surgery, and to indicate their confidence in achieving this result. Patients recorded postoperative outcomes achieved at number of weeks. Ordinal logistic regression multivariate modelling was used to examine predictors of postoperative satisfaction. Results. 90% of the patients were able to walk unaided and drive before or around the expected time scale at an average of five weeks' time. Persistent pain subsided at an average of two weeks post operatively which led to high satisfaction Although differences between patients' expectation and achievement were minimal at 6 weeks post-operatively, there was some discrepancy at 3 months, with patient expectations far exceeding achievement. The least satisfactory outcome was normal feeling of foot at six months follow up. There were significant correlations between failure to achieve expectations and the importance patients attached to recovery. Conclusions. This study underlines the importance of taking preoperative expectations into account to obtain an informed choice on the basis of the patient's preferences. Patients' pre-operative expectations of surgical outcome exceed their functional achievement but satisfaction remains high if pain control and ability to walk unaided is achieved early after hallux valgus corrective surgery

Introduction. Lower limb immobilisation with full casts is commonly used to manage fractures. There may be the need to split casts in an emergency, such as compartment syndrome, with no current consensus as to which technique is most effective in reducing pressure quickly. Our study aims to compare the reduction in pressure across lower leg compartments using three different cast splitting techniques. Methods. This study was done on a volunteer doctor. Pressure sensors were positioned at the anterior, posterior and lateral compartments. A single plaster technician applied below knee full casts with sequential layering and were allowed to dry as per manufacture instructions. Cast were split utilising three splitting methods; bivalve, tramline and single split and measurements taken when each layer was split. We compared results of ten repetitions for each splitting technique. Results. When the cast was initially cut there were significant reduction in pressure with the bivalve split (20.6 ± 0.76 N) when compared to both the single split (26.8 ± 1.13 N, P < 0.001) and tramline split (26.4 ± 0.90 N, P < 0.001). When the cast was spread there were significant reduction in pressure with the bivalve split (10.7 ± 0.83 units) when compared to both the single split (14.6 ± 0.85 N, P < 0.001) and tramline split (16.6 ± 0.77 N, P < 0.001). When the final layer of wool was released the pressure remained lower (statistically significant) in the bivalve split compared to both single split and tramline split. Conclusion. Our study demonstrates that bivalve cast splitting provided a more rapid reduction in pressure compared to other techniques across all three compartments. Our data shows that once down to skin, bivalve splitting continues to provide the lowest pressure compared to the other techniques. We recommend utilising bivalve when splitting a cast in an emergency


Aims

Arthroscopic microfracture is a conventional form of treatment for patients with osteochondritis of the talus, involving an area of < 1.5 cm2. However, some patients have persistent pain and limitation of movement in the early postoperative period. No studies have investigated the combined treatment of microfracture and shortwave treatment in these patients. The aim of this prospective single-centre, randomized, double-blind, placebo-controlled trial was to compare the outcome in patients treated with arthroscopic microfracture combined with radial extracorporeal shockwave therapy (rESWT) and arthroscopic microfracture alone, in patients with ostechondritis of the talus.

Methods

Patients were randomly enrolled into two groups. At three weeks postoperatively, the rESWT group was given shockwave treatment, once every other day, for five treatments. In the control group the head of the device which delivered the treatment had no energy output. The two groups were evaluated before surgery and at six weeks and three, six and 12 months postoperatively. The primary outcome measure was the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale. Secondary outcome measures included a visual analogue scale (VAS) score for pain and the area of bone marrow oedema of the talus as identified on sagittal fat suppression sequence MRI scans.

Aims

The number of revision total ankle arthroplasties (TAAs) which are undertaken is increasing. Few studies have reported the survival after this procedure. The primary aim of this study was to analyze the survival of revision ankle arthroplasties using large datasets. Secondary aims were to summarize the demographics of the patients, the indications for revision TAA, further operations, and predictors of survival.

Methods

The study combined data from the National Joint Registry and NHS Digital to report the survival of revision TAA. We have previously reported the failure rates and risk factors for failure after TAA, and the outcome of fusion after a failed TAA, using the same methodology. Survival was assessed using life tables and Kaplan Meier graphs. Cox proportional hazards regression models were fitted to compare failure rates.

MTPJ instability is very common yet there is no consensus of best surgical technique to repair it. The current techniques range from extensive release, K-wire fixation or plantar plate repair, which requires release of remaining intact plantar plate and all collaterals. Such varieties reflect a controversy regarding its aetiology. The aim of this study was to assess how much each structure contributes towards the stability of MTPJ and describing a simple technique designed by the senior author that can anatomically reconstruct all contributing structures to the pathology. Eleven cadaveric toes in two groups (five in group 1 and six in group 2) were included. Dorsal displacement (drawer test) was used to measure instability in an intact MTPJ followed by two different series of sequential sectioning of each part of collateral ligament (PCL and ACL) and part or complete plantar plate. Group 1 result showed that after incising PCL dorsal displacement was 0.51mm, PCL+ACL was 0.8mm and PCL+ACL+50% plantar plate was 2.39mm. Group 2 results showed that after incising 50% plantar plate dorsal displacement was 0.48mm, after full plantar plate 0.62mm, plantar plate +PCL was 0.74mm and plantar plate +PCL+ACL was 1.06mm. To produce significant instability, both collaterals on one side with combination of 50% plantar plate tear was needed. An isolated 50% tear of plantar plate caused less displacement of MTPJ compared to isolated collaterals. PCL contributed more towards the stability of MTPJ when the plantar plate was intact. Whereas, ACL contributed more stability when plantar plate was sectioned. The current practice of releasing the collaterals to gain access for repairing plantar plate by indirect method should be re-evaluated. A new technique of proximal tenotomy of extensor digitorum brevis tendon looped around the transverse ligament and attached to the neck of metatarsal reconstructs both structures (plantar plate and collaterals)

Aims

Treatment for delayed wound healing resulting from peripheral vascular diseases and diabetic foot ulcers remains a challenge. A novel surgical technique named ‘tibial cortex transverse transport’ (TTT) has been developed for treating peripheral ischaemia, with encouraging clinical effects. However, its underlying mechanisms remain unclear. In the present study, we explored the potential biological mechanisms of TTT surgery using various techniques in a rat TTT animal model.

Methods

A novel rat model of TTT was established with a designed external fixator, and effects on wound healing were investigated. Laser speckle perfusion imaging, vessel perfusion, histology, and immunohistochemistry were used to evaluate the wound healing processes.

Introduction. Crossover and claw toe deformity has traditionally been a very difficult condition to manage surgically, with high recurrence rates. Multiple methods have been used to treat this condition. Plantar plate “repair” has recently been advocated, with sutures used to repair an assumed tear. Based on clinical experience and anatomical studies (Deland et al. 1995), we believe the main pathology is a distal migration of the plantar plate complex resulting in exposure of the metatarsal to the thin posterior synovial attachment of the plate. The downward forces on the metatarsal head results in herniation of the head inferiorly. Accordingly we have developed a technique using full cuff release of the plantar plate complex that includes complete release of the collateral ligaments, repositioning the plantar plate anatomically and reinforcing the hernial defect with a synthetic mesh graft. Methods. 12 cases of severe crossover toe deformity have undergone plantar plate reconstruction using synthetic mesh graft in addition to other bony procedures (e.g. Weil's osteotomy, PIPJ fusion) since 2015 operated upon by the lead author. We collated data regarding patient satisfaction using Coughlin's Score (Coughlin 1991). We have also evaluated the sustainability of correction and any complications. Results. All patients reported “excellent” outcomes using Coughlin's score, with no cases of recurrence of any significance or complications, and a mean time to follow up of 180 days (range 23–23). Conclusions. Our understanding of the pathology of this condition is somewhat different from the conventional wisdom. Our technique of using a synthetic mesh graft to reconstruct the plantar plate complex shows promising results in terms of safety and decreased recurrence rate compared to traditional techniques. Further long term prospective results are required to confirm this pilot data

Objectives. The incidence of acute Achilles tendon rupture appears to be increasing. The aim of this study was to summarize various therapies for acute Achilles tendon rupture and discuss their relative merits. Methods. A PubMed search about the management of acute Achilles tendon rupture was performed. The search was open for original manuscripts and review papers limited to publication from January 2006 to July 2017. A total of 489 papers were identified initially and finally 323 articles were suitable for this review. Results. The treatments of acute Achilles tendon rupture include operative and nonoperative treatments. Operative treatments mainly consist of open repair, percutaneous repair, mini-open repair, and augmentative repair. Traditional open repair has lower re-rupture rates with higher risks of complications. Percutaneous repair and mini-open repair show similar re-rupture rates but lower overall complication rates when compared with open repair. Percutaneous repair requires vigilance against nerve damage. Functional rehabilitation combining protected weight-bearing and early controlled motion can effectively reduce re-rupture rates with satisfactory outcomes. Biological adjuncts help accelerating tendon healing by adhering rupture ends or releasing highly complex pools of signalling factors. Conclusion. The optimum treatment for complete rupture remains controversial. Both mini-open repair and functional protocols are attractive alternatives, while biotherapy is a potential future development.

Introduction. The Ponseti regime was introduced in Swansea in 2003 for the treatment of congenital talipes equinovarus (CTEV). The aim of this retrospective cohort study was to compare children treated with this regime with a historical group treated traditionally before then. Materials and Methods. Sixty children (89 feet) were treated with the Ponseti regime between 2003 and 2010. Their notes were compared with notes from 12 children (21 feet) treated between 1995 and 2002. Clinic attendance for serial manipulation and immobilisation (strap/cast) was compared using a two-tailed Mann Whitney U test. Major release surgery was compared using a two-tailed Fisher's Exact test. Results. Children in the historical cohort presented when they were 0–174 days old (median 1 day). They attended 3–35 times (median 22) for serial manipulation and strapping/ plasters. Major release surgery was undertaken on 14 feet (66.7%) when the children were 6–39 months old (median 9 months); 7 had revision surgery. The Ponseti cohort presented when they were 0–73 days old (median 10 days) and attended outpatients 2–19 times (median 7) for serial manipulation and casting. An Achilles tenotomy was undertaken in 54 feet (60.7%) when the children were 45–184 days old (median 71 days) and major release surgery in 17 feet (19.1%) when the children were 10–66 months old (median 21 months). Four children had revision surgery. Discussion. There is a significant reduction in outpatient attendances (Ua = 1313, p = <0.0001) for serial manipulation and reduced rate of release surgery (p = 4.56 × 10. −5. ) since the implementation of the Ponseti regime. The rate of revision surgery in both groups was not significant (p = 0.15), although these samples were small. Conclusion. The Ponseti regime is an effective initial treatment for infants with CTEV compared with traditional treatment. It has decreased the number of clinic attendances and the rate of major release surgery

We reviewed the outcome of distal chevron metatarsal osteotomy without tendon transfer in 19 consecutive patients (19 feet) with a hallux varus deformity following surgery for hallux valgus. All patients underwent distal chevron metatarsal osteotomy with medial displacement and a medial closing wedge osteotomy along with a medial capsular release. The mean hallux valgus angle improved from −11.6° pre-operatively to 4.7° postoperatively, the mean first-second intermetatarsal angle improved from −0.3° to 3.3° and the distal metatarsal articular angle from 9.5° to 2.3° and the first metatarsophalangeal joints became congruent post-operatively in all 19 feet. The mean relative length ratio of the metatarsus decreased from 1.01 to 0.99 and the mean American Orthopaedic Foot and Ankle Society score improved from 77 to 95 points. In two patients the hallux varus recurred. One was symptom-free but the other remained symptomatic after a repeat distal chevron osteotomy. There were no other complications. We consider that distal chevron metatarsal osteotomy with a medial wedge osteotomy and medial capsular release is a useful procedure for the correction of hallux varus after surgery for hallux valgus

We studied 11 patients with checkrein deformities of the hallux who underwent surgical treatment. Six had lengthening of the flexor hallucis longus tendon by Z-plasty in the midfoot, and five underwent release of adhesions and lengthening of the tendon by Z-plasty at the musculotendinous junction at the fracture site. All six patients who underwent Z-plasty at the midfoot showed complete correction of the deformity without recurrence. Of the five who had release of adhesions and Z-plasty of the tendon at the fracture site, two showed partial and one showed complete recurrence

Aims

This is a multicentre, non-inventor, prospective observational study of 503 INFINITY fixed bearing total ankle arthroplasties (TAAs). We report our early experience, complications, and radiological and functional outcomes.

Methods

Patients were recruited from 11 specialist centres between June 2016 and November 2019. Demographic, radiological, and functional outcome data (Ankle Osteoarthritis Scale, Manchester Oxford Questionnaire, and EuroQol five-dimension five-level score) were collected preoperatively, at six months, one year, and two years. The Canadian Orthopaedic Foot and Ankle Society (COFAS) grading system was used to stratify deformity. Early and late complications and reoperations were recorded as adverse events. Radiographs were assessed for lucencies, cysts, and/or subsidence.

Aims. The aim of this study was to report a single surgeon series of consecutive patients with moderate hallux valgus managed with a percutaneous extra-articular reverse-L chevron (PERC) osteotomy. . Patients and Methods. A total of 38 patients underwent 45 procedures. There were 35 women and three men. The mean age of the patients was 48 years (17 to 69). An additional percutaneous Akin osteotomy was performed in 37 feet and percutaneous lateral capsular release was performed in 22 feet. Clinical and radiological assessments included the type of forefoot, range of movement, the American Orthopedic Foot and Ankle (AOFAS) score, a subjective rating and radiological parameters. . The mean follow-up was 59.1 months (45.9 to 75.2). No patients were lost to follow-up. Results. The mean AOFAS score increased from 62.5 (30 to 80) pre-operatively to 97.1 (75 to 100) post-operatively. A total of 37 patients (97%) were satisfied. At the last follow up there was a statistically significant decrease in the hallux valgus angle, the intermetatarsal angle and the proximal articular set angle. The range of movement of the first metatarsophalangeal joint improved significantly.. There was more improvement in the range of movement in patients who had fixation of the osteotomy of the proximal phalanx. Conclusion. Preliminary results of this percutaneous approach are promising. This technique is reliable and reproducible. Its main asset is that it maintains an excellent range of movement. Take home message: The PERC osteotomy procedure is an effective approach for surgical management of moderate hallux valgus which combines the benefits of percutaneous surgery with the versatility of the chevron osteotomy whilst maintaining excellent first MTPJ range of motion.

Aims

In our unit, we adopt a two-stage surgical reconstruction approach using internal fixation for the management of infected Charcot foot deformity. We evaluate our experience with this functional limb salvage method.

Methods

We conducted a retrospective analysis of prospectively collected data of all patients with infected Charcot foot deformity who underwent two-stage reconstruction with internal fixation between July 2011 and November 2019, with a minimum of 12 months’ follow-up.
