Abstract
The quadriceps tendon (QT) functions as one of the primary knee extensor mechanisms. The risk of QT tendinopathy increases with age, which also impacts the risk of QT rupture. This injury typically occurs as a result of an abrupt eccentric contraction with knee hyperflexion. A QT rupture has detrimental effects on quality of life and function. Surgical repair provides improved outcomes, but the risk of re-rupture is still present, with limited literature discussing outcomes. This technical note describes the repair of a chronic QT re-rupture fixated with suture anchors and semitendinosus tendon autograft augmentation.
