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. 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
Methods
Achilles tendinopathy is characterised by chronic degeneration of the Achilles tendon, usually secondary to injury or overuse. Extracorporeal shockwave treatment (ESWT) is of potential benefit in refractory cases where conservative management with analgesia, physiotherapy and corticosteroid injection have been unsuccessful. Patients with refractory Achilles tendinopathy enrolled between October 2010 and October 2011 received three sessions of ESWT over three weeks. Patients completed visual analogue scale (VAS) scores for pain at rest and on activity and the Victorian Institute of Sport Assessment-Achilles (VISA-A) questionnaire pre-treatment. These outcome measures and a six-point Likert satisfaction scale were reassessed at six and 16 weeks post treatment. 51 patients completed follow up. Mean age was 56 (34–80) years and mean length of symptoms 34 (4–252) months. Significant improvement (p<0.05) in VAS scores (rest and activity) and VISA-A scores was observed between baseline and 16 weeks. Mean Likert score was 3 (somewhat improved) at 16 weeks. Patients suffering Achilles tendinopathy for longer than 25 months had significantly less improvement than those affected for a shorter period. This study suggests that ESWT improves subjective and objective outcomes in patients with refractory Achilles tendinopathy.
