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

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

Aim. 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. Methods. Between 1998 and 2005, 111 STAR were implanted into 98 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, AOFAS Hindfoot score, Foot Function Index (FFI), Ankle Osteoarthritis Scale (AOS) were completed. Sixty four patients were followed with these scores prospectively and 50 retrospectively. Both groups had prospective radiographic follow-up using measures described by Hintermann et al, and Wood et al. Results. The average follow-up for both groups was 6.3 years (4.6-8.5 years). Of the 111 implanted STARs, 12 (11%) STARs had a metal component revision performed giving an overall survival of 89% (99) of the originally implanted metal components at the conclusion of the study. Thirty five patients (32%) had a re-operation performed during the follow-up period, 15 procedures (14%) were for replacement of fractured polyethylene liners. The sustained benefit across questionnaires from the STAR persisted to final follow up. Some evidence of osteolysis was present in 110/111 (99%) ankles at the final follow-up, more commonly around the talar component. No significant differences between the two centres in pre-operative or intra-operative data were identified. Conclusion. The STAR, in the mid-term, shows acceptable survival and revision rates. There are, however, some concerning findings on radiographic follow-up. Further investigation and longer follow-up is required to substantiate these concerns

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 hindfoot score for pain improved from 0 to 36 (max 40) and for function from 25 to 35 (max 60). Three have failed. One ankle had a 25-degree valgus deformity pre-operatively and this recurred and caused failure at 11 months. The second failed at 34 months due to aseptic loosening of the talar component. Both of these were converted to tibio-talo-calcaneal fusions with an intra-medullary nail. The third failure had never provided satisfactory pain relief in spite of appearing satisfactory on clinical and radiological examination. Exploratory surgery was carried out at 36 months but failed to produce an improvement and at 61 months the decision was made to revise the replacement to a fusion. However, due to concurrent health problems, this has not yet been done. We offer replacement to patients with severe polyarticular rheumatoid disease especially if there is a stiff but well aligned hindfoot. In the light of increased experience, we now consider valgus or varus deformity of greater than 20 degrees to be a contra-indication to replacement. This is because the deformity tends to recur leading to pain, loosening and failure

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 hindfoot score and Lower Extremity Functional Scale (LEFS) was utilised to assess pain and function, Tegner score to evaluate activity) were evaluated at an average follow-up of 17 months. Complications, if any, were also recorded. There were no re-ruptures and all patients returned to normal work (average time 9.2 weeks) and all but one returned to their previous level of recreational sporting activity (average time 20.8 weeks). The postoperative performance testing showed positive results with the mean decrease in calf circumference of affected leg was 1.0 cm (range, −0.5 to 2.0), and every patient was able to perform at least one heel-raise with the mean heel raise difference being −3.8 repetitions (range, −1 to −10 reps) when compared to the other leg. In terms of functional outcomes, all patients reported very good results. The mean AOFAS score postoperatively was 83.4% (range, 74% to 100%) and the mean LEFS score was 82.5% (range, 45 to 100%). The mean preoperative Tegner score was 4.75 (range, 2 to 8) and the postoperative score was 3.75 (range, 2 to 7). The results of our preliminary clinical series indicate that LARS ligament repair of acute Achilles tendon ruptures provides a reliable and effective technique for repair. It eliminates the need for graft harvesting, it decreases postoperative complications, but most importantly, patients have improved functional outcomes

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 Hindfoot Pirani score:2.5 (left 2.55, right 2.5 Range 1.5–3). Mean post operative Pirani score:2.0(left 2.0, right 2.0 Range 0.5–6). Mean postoperative Hindfoot pirani score:1.45. Three patients had severe arthrogryphosis, of whom 2 did not correct requiring open surgery. All idiopathic CTEV feet corrected with a range of 5–20 degrees of dorsiflexion at last follow up. The mean follow up was 43.64 months (range 7–96 months). Conclusions. The calcaneal pulldown technique is a useful complmentary adjunct to the Ponseti method. It enables the correction of equinus without the need for open surgery. Since the introduction of the technique to our unit it has negated the need for open surgery. The results are encouraging, it is a simple effective technique that can help in difficult CTEV cases

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 hindfoot score post-operatively is 65, with a mean improvement of 40 points from the pre-operative score in the TTC nail group. Post-operative complications included deep infection, amputation and a non-union rate of 10% overall. In the humeral nail group, four symptomatic stress reactions [8%] and three fractures of the tibia [6%] occurred at the tip of the nail. No stress-riser effect has to date been seen in the TTC nail group. Prominent metalwork removal has also been significantly reduced in the TTC nail group. Our results show hindfoot fusion using a curved intramedullary nail to be an effective technique in complex cases of hindfoot arthritis and deformity. Anatomically specific alterations to the nail have resulted in a significant reduction in certain complications. Alternate proximal locking options in the TTC nail have reduced prominent metalwork and, more significantly, the incidence of stress reactions and fractures appears to have been eliminated
