Prevention of Intraoperative Extensor Mechanism Injury in Total Knee Arthroplasty

摘要

Avoiding intraoperative injuries to the extensor mechanism during total knee arthroplasty is paramount to obtaining good clinical outcomes. Knowledge of the anatomy and blood supply of the extensor mechanism, in addition to identification of risk factors to sustain these injuries, provides the basic principles to prevent them. A summary of different techniques to prevent injuries of each anatomical component of the extensor mechanism during total knee arthroplasty is provided.
