Achilles Tendon Repair Strategies
Summary
The Achilles tendon, the largest and strongest tendon in the human body, is essential for gait, propulsion and postural stability. Strategies to repair ruptures range from non-operative approaches—such as immobilisation in plaster casts or functional bracing with early weight-bearing—to surgical techniques including open repair, minimally invasive percutaneous suturing and autograft or allograft augmentation. Biomechanical considerations guide choice of suture configuration and tension, with Krackow-type and pull-out methods frequently employed to optimise tensile strength and minimise elongation. Rehabilitation protocols vary from strict immobilisation to accelerated functional mobilisation, exploiting mechanotransduction to enhance collagen synthesis and tendon remodelling. Emerging adjuncts include biological therapies—growth factors, cell-based scaffolds and gene delivery systems—aimed at modulating inflammatory and proliferative phases of healing. Clinical challenges encompass re-rupture risk, wound complications, sural nerve injury and long-term functional deficits, while healthcare systems evaluate cost-effectiveness and patient-reported outcomes. Global incidence of Achilles tendon injury is rising in both athletic and ageing populations, driving research toward personalised treatment algorithms, predictive biomarkers and standardised outcome measures to improve safety, expedite recovery and restore performance.
