Technique for revision reconstruction of a chronic quadriceps tendon re-rupture using Achilles tendon allograft

Quadriceps tendon ruptures can substantially diminish the quality of life for patients, imposing significant functional limitations and persistent pain if untreated. Re-injuring the tendon post-fixation presents further surgical challenges, often complicated by scar tissue development and compromised vascular integrity. In this technical note, we describe a novel technique for revising quadriceps tendon fixation failures using an Achilles tendon allograft through bone tunnels and an augmentation with a trans-tendinous pseudo-Pulvertaft weave. Our technique aims to enhance structural integrity and reduce re-injury risk, offering an effective operative solution to challenges associated with quadriceps tendon re-ruptures.
