Arthroscopic Versus Open Subtalar Arthrodesis for the Treatment of Subtalar Arthritis

The goal of this clinical trial is to compare two surgical approaches for treating symptomatic subtalar arthritis in patients who have failed conservative treatment. The main questions it aims to answer are: What is the fusion rate for each surgical technique? Which technique achieves bony union faster with fewer complications? Researchers will compare arthroscopic subtalar arthrodesis (ASTA) using a combined three-to-four portal approach to open in situ subtalar arthrodesis (ISTA) to see if one technique results in superior fusion rates, faster healing, and better functional outcomes. Participants will: Undergo one of two surgical procedures (either ASTA or ISTA) Attend follow-up visits at 6 weeks, 3 months, 6 months, and 12 months after surgery Have X-rays taken to assess fusion and bone healing Complete pain and function questionnaires at each visit
