Suture Anchor Repair with V-Y Plasty and Achilles Allograft Augmentation for Chronic Quadriceps Tendon Injury.

Abstract

Despite an overall incidence that remains low, quadriceps tendon injuries represent a common disorder of the knee extensor mechanism. Persistent pain, weakness, and loss of terminal extension can lead to poor clinical outcomes and significant functional impairment. In the acute setting, approach to management often includes primary repair of the injured tendon that can lead to excellent clinical outcomes. However, a delayed or missed diagnosis can bring forth a clinical scenario that can be difficult to manage thereafter. In the chronically injured tendon, challenges can be linked to limited tendon excursion, poor tissue quality, and increased risk of reinjury.
