Arthroscopic Versus Open Subtalar Arthrodesis for the Treatment of Subtalar Arthritis

Egypt40 participantsStarted 2023-12-05

Plain-language summary

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

Inclusion Criteria: * Clinically and radiographically confirmed symptomatic subtalar arthritis (post-traumatic, primary osteoarthritis, inflammatory or cured post-infective arthritis, symptomatic talocalcaneal coalition, or isolated subtalar arthrosis secondary to pes planovalgus deformity) * Failure of an adequate trial of non-operative treatment for a minimum of six months * Skeletal maturity: patients aged 18 years or older * Ability and willingness to provide written informed consent and to comply fully with the scheduled postoperative follow-up protocol Exclusion Criteria: * Primary subtalar arthrodesis performed for an acute, displaced intra-articular calcaneal fracture * Arthrodesis planned in conjunction with other simultaneous ipsilateral hindfoot procedures * Patients with open physes (skeletal immaturity) * Indication for a distraction-type arthrodesis requiring structural bone graft * History of previous or current active infection at the planned operative site * Previous failed attempt at subtalar arthrodesis * Presence of significant peripheral vascular disease or other major medical comorbidities precluding safe surgical intervention
