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. 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.Purpose
Materials/Methods
Coronal plane deformity can pose difficulties with balancing in Total Ankle Replacement (TAR). Current reports outline improved outcomes in the presence of varus deformity. Soft tissue balancing techniques are well described, but are limited by no link to eitiology and pathoanatomy of the deformity. A prospective review of all the TAR by the senior author was performed to identify cases of pre-operative varus greater than 10°. A chart review was performed to identify aetiology, intraoperative findings, and operative techniques to achieve a balanced TAR. X-rays were examined to measure deformity and amount of correction. Volumetric rendering and segmentalisation was performed on pre- and post-CTs to identify anatomical defects, osteophyte formation, rotational and translational changes of the hindfoot joints.Introduction
Method
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. 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 Aim
