Quadriceps Tendon Repair Using Double-Row Suture Anchor Fixation

Abstract

Quadriceps tendon ruptures compromise the knee extensor mechanism and cause an inability to ambulate and significant functional limitations. Therefore, the vast majority of quadriceps tendon ruptures are indicated for operative intervention to restore patient mobility and function. Although these injuries were traditionally repaired using a transosseous repair technique, recent literature has shown that suture anchor repair may offer biomechanical advantages. Additionally, research in other areas of orthopaedics has found that a double-row suture anchor construct can offer additional biomechanical strength to tendinous repair. This technical note describes a safe and effective quadriceps tendon repair using a double-row suture anchor construct.
