Description

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.

Interventions

Single-row repair of the Achilles tendon at its calcaneal insertion (Procedure)
single-row (2 anchors)
Double-row repair of the Achilles tendon at its calcaneal insertion (Procedure)
double-row (4 anchors)
