Extensor mechanism repair: A synthetic mesh approach

Complications involving the extensor mechanism have a devastating effect on overall function following a primary or revision total knee arthroplasty. There are intraoperative, postoperative, and patient-related risk factors that can increase the occurrence of this complication. The results of previously described techniques utilizing direct repair, allograft reconstruction, and/or autograft reconstruction have been discouraging. The purpose of this article is to describe a technique utilizing a synthetic mesh for reconstruction of extensor mechanism disruptions after total knee arthroplasty.
