Abstract

Disruption of the extensor mechanism during total knee arthroplasty may result in devastating complications and outcomes. Most commonly there are seven problems encountered with the extensor mechanism following total knee arthroplasty. These are quadriceps tendon rupture, patellar tendon disruption, patellar crepitus, periprosthetic patellar fracture, soft tissue impingement, patellofemoral instability, and osteonecrosis of the patella [1]. In a revision scenario, there are often many barriers to a straightforward exposure in which to avoid/address these issues. Difficult exposure can often place the extensor mechanism at risk. This chapter will address the techniques for proper exposure, risk factors for extensor mechanism problems, and the management and reconstruction of extensor mechanism injury.
