Abstract
BackgroundSeveral techniques have been described for the primary repair of quadriceps tendon ruptures but there is a paucity of literature on operative management of chronic/recurrent quadriceps tendon ruptures. We describe a novel technique for the revision of quadriceps tendon ruptures which uses hamstring, prolene mesh and autologous conditioned plasma augmentation. MethodsOur patient was an independently mobile, active 61year-old man who sustained staggered, bilateral quadriceps tendon ruptures. He had two failed direct repairs on the left side. The patient was unable to actively extend his knee.On the third attempt, despite maximising quadriceps tendon length using the Codivilla technique the gap remained significant. The left and right semitendinosus and left gracilis tendons were thus harvested and used to augment our repair. A prolene mesh, sized to fit the whole length quadriceps tendon and patella, was then secured to the repair to reinforce it. The repair site was finally injected with autologous conditioned plasma. ResultsSatisfactory post-operative outcomes were achieved. The patient was pain-free and able to maintain straight leg raise with a 10 degrees extensor lag at his four months review in clinic. ConclusionsWe were able to achieve a stable construct with combination of both well-established and novel tendon lengthening techniques, in addition to mesh and biological augmentation. In our experience this surgical procedure is suitable for the treatment of a large tendon gap defect and will withstand high force transmission. Level of EvidenceLevel 5 Evidence
