BACKGROUND: The goal of this study was to compare results with arthroscopic posterior subtalar arthrodesis between @entity1 treated for @entity85 ( @entity85 ) due to @entity12290 and @entity1 with @entity625 . METHODS: Retrospective case series of 61 consecutive @entity1 (group 1: @entity625 , n = 37; group 2: @entity85 , n = 24) averaging 49 years of age (range, 21-72 years) undergoing posterior arthroscopic subtalar arthrodesis via 1 or 2 percutaneous 6.5- to 7.3-mm screws, with a mean follow-up of 57.5 months (range, 24-105 months). Fusion was defined as the appearance of bony trabeculae across the subtalar joint on standard x-rays, along with clinical signs of union. RESULTS: @entity1 with @entity625 (group 1) were more predominantly male and younger than @entity1 treated for @entity85 (group 2). Overall, we achieved a 95.1% radiologic union rate after an average of 11.7 weeks. Complications appeared in 14.8% of @entity1 . Union rate and complications did not differ significantly between groups. American Orthopaedic Foot _ Ankle Society (AOFAS) scores improved significantly for both @entity1 groups, although @entity1 with @entity85 showed significantly larger improvement and higher postoperative AOFAS scores, even after adjusting for age and sex (mean improvement in AOFAS scores: 27.0    9.1 points for the @entity625 group vs 34.9    7.4 points for the @entity85 group; P < .001). CONCLUSIONS: Arthroscopic subtalar arthrodesis was a safe and reliable technique, with consistent improvement in AOFAS scores throughout different @entity1 subgroups, as well as comparable time to union and complication rates. Improvements were larger for @entity1 treated for @entity85 , even after adjusting for age and sex. LEVEL OF EVIDENCE: Level III, retrospective case series.
