About this trial
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.

Achilles Tendon Surgery
Procedure/SurgeryAchilles 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.

Visual Analogue Scale
The VAS score (Visual Analogue Scale) is a simple and widely used method for assessing subjective experiences, such as pain intensity, fatigue, or discomfort. It typically consists of a horizontal or vertical line, usually 10 cm in length, with endpoints representing the extremes of the experience being measured: 0: "No pain" (or "no discomfort"). 10: "Worst pain imaginable" (or "maximum discomfort") Evaluated during the 3 first days after surgery, at 6 months, 1 year, 2 years and every 2 years
Time frame
From the surgery to the and of the follow-up (20 years for each patient)3
Ankle Ligament Reconstruction - Return to Sport Injury score
The ALR-RSI (Ankle Ligament Reconstruction - Return to Sport Injury) score is used to assess the patient's psychological state and apprehension regarding their return to sports activities. The score ranges from 0% (the lowest level of psychological readiness) to 100% (the highest level of psychological readiness). Questionnairy at 6 months, 1 year, 2 years and every 2 years
Time frame
From the surgery to the end of foolow-up (20 years for each patient)4
Foot an Ankle Ability Measure
Foot and Ankle Ability Measure (FAAM) is a tool designed to assess a patient's functional abilities and symptoms specifically related to their foot and ankle during daily activities and sports. It consists of two subscales: Activities of Daily Living (ADL): 21 items. Sports: 8 items. Each item is rated on a 5-point Likert scale: 4 = No difficulty 3 = Slight difficulty 2 = Moderate difficulty 1 = Extreme difficulty 0 = Unable to perform Scoring : Add the scores for all items within the subscale to calculate the total item score. Multiply the total number of answered items by 4 to determine the highest potential score (e.g., 84 for ADL and 32 for Sports if all items are answered). Divide the total item score by the highest potential score and multiply by 100. This gives the FAAM score, which ranges from 0% (lowest function) to 100% (highest function). Interpretation : A higher score indicates a greater level of physical function. Measured at 6 months, 1 year, 2 years and every 2 years
