| description | Category: Ankle Arthritis Introduction/Purpose: Ankle joint distraction arthroplasty (AJDA) is an alternative surgical procedure for the management of moderate to severe ankle osteoarthritis. However, the benefit of this procedure and failure relative factors are still in debate. The purpose of current study was to evaluate the functional outcomes of AJDA in treatment of moderate to severe ankle OA; and to evaluate the relative factors correlated with treatment failure. Methods: Forty-six van Dijk stage II and III ankle osteoarthritis patients were included. Fifteen males and 31 females with a mean age of 54.8 (range, 42-71) years were followed with a mean of 42.8 (range, 24-68) months. The Ankle Osteoarthritis Scale (AOS) and American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score were used for functional outcomes evaluation. The talar tilt (TT) angle and ankle joint space distance (AJSD) were evaluated. The risk ratio (RR) was calculated for each potential failure relative factor. Results: The AOS and AOFAS scores were significantly improved at the last followup time (P＜0.01). The AJSD was improved in 61% of patients, and with a significant improvement compared with the preoperative conditions (P＜0.01). The TT angle and range of motion reached no significant difference. The failure rate was 21.7%. Patients with large TT (>=5°) angle (RR=3.81, 95%CI: 1.28-11.33, P=0.02) and obesity (RR=3.58, 95%CI: 1.30-9.89, P=0.01) were found have positive correlation with failure. No correlation was found between failure and gender, or overweight, or side, or age, or type and stage of OA, or pin infection. Conclusion: Current study confirmed the early functional outcomes of ankle distraction arthroplasty. However, this procedure still has a relatively high failure rate, especially for those obesity patients and the patients with large TT angles. |
