Abstract
Clinical outcomes between reattachment of the superior peroneal retinaculum (SPR) and the bone block procedure were compared in this study to elucidate which procedure was safer and more effective. From 2012 to 2016, 25 patients with recurrent peroneal tendon dislocation underwent the bone block procedure (group A), and another 22 patients underwent reattachment of the SPR (group B). American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Ankle Activity Score (AAS), time to return to sports activity, rate of return to sports level, range of motion (ROM) of the ankle, rate of recurrence, and overall patient satisfaction were collected to evaluate outcomes between the two groups. In group A, 24 patients followed up at a mean period of 42.5 ± 16.7 months. The mean postoperative AOFAS score was 92.9 ± 3.9. The median time to return to sports activity was 6.0 months (IQR 4.3-6.0 months) with 19 patients (79.2%) returning to their previous sports level. Two patients experienced recurrent dislocation, and 22 patients (91.7%) were satisfied with the procedure. In group B, 20 patients followed up at a mean period of 35.8 ± 15.3 months. The mean postoperative AOFAS score was 95.0 ± 4.2. The median time to return to sports activity was 5.0 months (IQR 4.0-5.0 months) with 18 patients (90.0%) returning to their previous sports level. No recurrence was reported, and 18 patients (90.0%) were satisfied with the procedure. The time to return to sports activity in group B was significantly shorter than that in group A. There was no significant difference in complications or clinical outcomes between the two procedures. Both procedures offered satisfactory results for recurrent peroneal tendon dislocation with low rates of recurrence and complications. However, the time to return to sports activity after the reattachment of the SPR was shorter than that after the bone block procedure. Retrospective Comparative Study, Level III.
