Summary

Achilles insertional tendinopathy may require surgical debridement and tendon reattachment when non-operative treatment fails. Single-row and double-row repairs are used, with biomechanical studies favoring double-row, but clinical evidence of improved outcomes is lacking and costs are higher. This multi-center randomized trial will use the VISA-A score to compare outcomes and inform cost-effective, evidence-based surgical care.

Detailed description

Double-row repairs for Achilles insertional tendinopathy have been shown biomechanically to be stronger than single-row repairs, but clinical studies have not demonstrated clear advantages. Existing comparative studies are limited by retrospective designs and use of non-validated outcome measures such as AOFAS, VAS, and SF-36 Physical Function. No prospective randomized trials have evaluated clinical outcomes of single-row versus double-row repairs. This multi-center randomized controlled trial will use the disease-specific Victorian Institute of Sports Assessment-Achilles (VISA-A) score to compare clinical outcomes between single-row and double-row repairs, providing high-quality evidence to guide optimal surgical management.
