Abstract
BACKGROUND: It is unclear whether simultaneous surgery for posterior ankle impingement syndrome (PAIS) and concomitant ankle disorders, such as anterior ankle impingement syndrome (AAIS), lateral ankle instability (LAI), and osteochondral lesion of the talus (OLT), allows for early return to athletic activity. METHODS: Ninety-seven patients who engaged in athletic activity (mean age 27 [range 18-43] years) and were treated by a hindfoot endoscopic approach for PAIS alone or simultaneously for PAIS and concomitant ankle disorders were included in this study. The patients were divided into four groups: PAIS alone (group A, n = 61), PAIS with AAIS (group B, n = 8), PAIS with LAI with or without AAIS (group C, n = 20), and PAIS with OLT with or without AAIS/LAI (group D, n = 8). In all patients, the concomitant ankle disorder was treated simultaneously by arthroscopic debridement for AAIS, bone marrow stimulation or autologous cancellous bone transplantation for OLT, and anterior talofibular ligament repair or reconstruction for LAI. American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale scores before and 2 years after surgery and times from surgery to resuming training and athletic activity were compared between the groups. RESULTS: Mean AOFAS score improved significantly after surgery in all groups (groups A and C, P < .0001; groups B and D: P < .05). The time taken to return to training was significantly longer in group D than in groups A, B, and C (all P < .01) as was the time taken to return to athletic activity in groups C and D when compared with group A (P < .01); however, there were no significant differences in this regard between groups B and C. CONCLUSION: Concomitant surgery for AAIS and LAI with PAIS did not delay the postoperative start of training, however, concomitant surgery for LAI and OLT delayed the return to athletic activity when compared with PAIS surgery alone. STUDY DESIGN: Clinical Retrospective Comparative Study.
