Single-Row Versus Double-Row Repair for Achilles Insertional Tendinopathy

Starting soon · Not applicable

Conditions studied: Achilles Insertional Tendinopathy, Achilles Tendinopathy

In brief

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.
