Reconstruction of a Chronic Ruptured Patellar Tendon With Achilles Tendon Allograft After Total Knee Arthroplasty

Abstract

Patellar tendon rupture after total knee arthroplasty is a severe complication that can result from a combination of patient-specific risk factors, surgical technique, and trauma. Several methods have been proposed to address this pathology; however, a “gold standard” has yet to be defined. In this Technical Note, the authors describe a modified surgical technique for patellar tendon reconstruction after total knee arthroplasty using a fresh-frozen Achilles tendon allograft with an attached calcaneal bone plug. Our technique aims to restore the extensor mechanism’s function while offering superior stability and durability.
