Patellar Tendon Revision Reconstruction Using Transosseous Patella All-Suture Anchors, Semitendinosus Autograft, and Achilles Allograft.

Abstract

Patellar tendon rupture is an uncommon but highly treatable injury, with excellent repair outcomes and low reoperation rates. Chronic patellar tendon ruptures or repair failures pose a clinical challenge, but the success rates of reconstruction with extensor mechanism allograft or autograft are reported to be high in the literature. Still, the reconstruction of chronic patellar tendon ruptures can be technically complex and yield inferior outcomes compared with primary repair. A wide array of operative strategies exists to combat these poor results, ranging from Achilles allograft augmentation to transosseous suture constructs. Our combined revision reconstruction approach employs knotless suture anchors, semitendinosus autograft, Achilles tendon allograft, and circumferential suture cerclage. This surgical technique confers the postoperative benefits of autograft and allograft augmentation while preserving the native patellar tendon tissue.
