Inclusion Criteria

Inclusion criteria were patients who were older than 18 years old with isolated and end-staged subtalar joint arthritis (The diagnosis was confirmed by history of pain and swelling over the subtalar joint, tenderness at subtalar joint line or limited subtalar motion on physical examination, diagnostic injection using 1% lidocaine intra-articular injection could get rid of pain, and weight bearing radiograph or CT scan demonstrated arthritis of subtalar joint). All patients had failure of conservative treatment for at least 6 months (After diagnosis, all patient was initially treated with non-operative treatment including NSAIDs, activities modification, decrease body weight, shoes modifications, orthotics, and/or steroid injection). Patients agreed to participate this study and were able to complete all pre-operative and post-operative questionnaires at pre- and post-operative visit or via telephone interview.

Exclusion Criteria

Exclusion criteria included patients who had arthritis on adjacent joints such as ankle or midfoot joints arthritis. Patient who had significant bone loss on subtalar joint surface that was required bone graft substitution. Patient who has significant malalignment of subtalar joint with tarsal coalition that required calcaneal slide osteotomy or resection of coalition. Patients who had surgery in foot and ankle regions and arthroscopic subtalar joint arthrodesis simultaneously. Patients who had underlying diseases which might be interfered with outcomes measurement such as diabetes, peripheral neuropathy, previous nerve injury on lateral side of foot and ankle region, previous skin graft or flap coverage over subtalar joint region.
