Abstract

Complications of the extensor mechanism after total knee arthroplasty are uncommon and present a challenge to the surgical team. No commonly accepted classifications or treatment strategies exist since these depend on institutional, national, and healthcare-system restrictions and possibilities. The goal of this chapter is to provide an overview of existing treatment options for the different possible scenarios. These treatment options reflect the experience of the author and do not display all possibilities available.
