Abstract

The extensor mechanism of the knee is essential for everyday functioning such as ambulation, standing from a seated position and walking up and down stairs. Injury to the extensor mechanism can be potentially devastating to everyday life. Disorders of the knee extensor apparatus may arise at any level. This chapter has discussed rupture of the quadriceps and patellar tendon, and tibial tubercle avulsion fractures. Disruption of the extensor mechanism in the context of total knee arthroplasty invariably will lead to unfavourable functional outcomes and subsequent poor prognoses, following what is usually a hugely successful procedure. Current treatment methods have been described, including the use of extensor mechanism allografts.
