Keyhole surgery may speed up ankle fusion recovery
NCT ID NCT07486596
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This trial compares two surgical methods for treating subtalar arthritis when other treatments fail. Forty adults will receive either arthroscopic (keyhole) or open surgery to fuse the joint. Researchers will track fusion rates, healing time, and complications over 12 months to see which approach works better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- surgery (arthroscopic or open subtalar arthrodesis)
- What this could lead to
- If one technique proves better, it could lead to faster healing and fewer complications for people with subtalar arthritis needing fusion surgery.
- What could go wrong
- This is a small, early-stage trial with only 40 participants, so results may not apply to everyone. Both surgeries carry risks like infection, nerve damage, or non-union.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
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
