Early full weight-bearing and gait exercise after cemented total ankle arthroplasty with a modified anterolateral approach.

Objectives: According to the conventional postoperative procedure after total ankle arthroplasty (TAA), mobilization and weight-bearing is currently started after completion of wound healing. Recently, early mobilization for dorsiflexion after TAA with modified antero-lateral approach was reported to be feasible and safe. To investigate the further possibility of expediting rehabilitation, this study evaluated the feasibility and safety of early full weight-bearing and gait exercise after cemented TAA. Materials and Methods: This retrospective, observational study investigated 23 consecutive ankles (OA: 14 ankles, RA: 9 ankles) that had received cemented TAA with a modified antero-lateral approach. These ankles were divided into three groups 1. conventional postoperative protocol, 2. early dorsiflexion protocol, 3. early dorsiflexion+full weight-bearing protocol. Postoperative wound complications were observed and recorded. Number of days for hospitalization was also evaluated. Results: No postoperative complications related to wound healing were observed even after early full weight-bearing and gait exercise. Days for hospitalization was significantly shortened in early full weight-bearing and gait exercise group (group 3) from 35-38 days to 24 days. Conclusions: Within this small number of cases, early full weight-bearing and gait exercise from 7 days after cemented TAA was feasible and safe with the modified antero-lateral approach. Combination of early dorsiflexion mobilization and weight-bearing/gait exercise contributed to shortening the hospitalization day. Innovations in postoperative procedures for rehabilitation after TAA can be expected. [ABSTRACT FROM AUTHOR]
