French Achilles Tendon Surgery Cohort Study

NCT07338110 | Recruiting

• 1 other identifier: AchilleCDS
• Study Type: observational
• Target: 5,000
• Locations: 1 country
• Sites: 1

Brief Summary

This 20-year prospective cohort study monitors patients following Achilles tendon repair to assess re-rupture rates, long-term functional outcomes, return-to-sport rates, and procedure-related complications. The aim is to better understand the long-term durability and clinical effectiveness of Achilles tendon repair techniques to optimize patient outcomes.

Conditions

Achilles Injuries Tendon; Surgery

Outcome Measures

Primary Outcomes (1)

• Number of Participants with Re-rupture of the Achilles Tendon

• Foot an Ankle Ability Measure

  From the surgery to the end of follow-up (20 years for each patient)

• Achilles Tendon Total Rupture Score

  From the surgery to the end of follow-up (20 years for each patient)

Interventions

Achilles Tendon Surgery PROCEDURE

Achilles tendon repair involves reattaching the torn ends of the tendon to restore its continuity and functional tension. This technique is typically used for acute ruptures where the tendon quality is preserved and direct suture is feasible. Achilles tendon reconstruction is performed in chronic ruptures, re-ruptures, or cases with significant tendon degeneration or retraction, where direct repair is not possible. The procedure may involve tendon transfers such as the flexor hallucis longus (FHL), or autografts from the triceps surae aponeurosis or hamstring tendons (gracilis-semitendinosus, DIDT). These techniques aim to restore tendon length, strength, and function. In some cases, augmentation techniques (e.g., pedicled or free grafts) are used to reinforce the repair, particularly in patients with poor tendon tissue quality or high functional demands.
