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.

Detailed description

This study is a long-term cohort analysis involving patients who have undergone Achilles tendon repair surgery. The goal is to follow these patients over a 20-year period to assess several key outcomes. Specifically, the study aims to evaluate the rate of re-ruptures, the rate and quality of return to sport, long-term functional outcomes using validated scoring systems, and the incidence of procedure-related complications. By collecting detailed and consistent data over two decades, this research seeks to provide valuable insights into the durability and effectiveness of Achilles tendon repair surgery, ultimately contributing to a better understanding of the procedure and improved patient care.

Interventions

Type	Name	Description
PROCEDURE	Achilles Tendon Surgery	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.
