Run by Chirurgie Du Sport · NCT07338110 · Data updated 2026-11-12
This 20-year follow-up will see if people who had Achilles tendon repair keep function, avoid re-rupture, and return to sport.

Is this trial a fit for you?
✓Likely a good fit
Patients who undergo Achilles tendon repair at the Paris center and agree to long-term follow-up are ideal candidates.
✕Probably not a fit
People managed without surgery or those unable or unwilling to attend follow-up visits in Paris are unlikely to benefit from the results.

What this trial studies
This is a prospective cohort that will follow patients who undergo Achilles tendon repair at Chirurgie du Sport in Paris for 20 years. Participants will attend scheduled follow-up visits with standardized data collection using validated functional scores and complication tracking. Key outcomes include re-rupture rates, return-to-sport rates, long-term functional outcomes, and procedure-related complications. Enrollment excludes patients who refuse participation and all data will be analyzed longitudinally to describe durability of repair techniques.
Why it matters
Potential benefit: If successful, the findings could help surgeons choose repair techniques that lower re-rupture risk and improve long-term function and return-to-sport.
How similar studies have gone: Shorter-term cohorts and trials have reported useful data on re-rupture and function, but prospective 20-year follow-up datasets are relatively uncommon.
