Abstract
Articular cartilage injuries of the knee can be debilitating if not treated properly. Once an articular cartilage injury is sustained there are a variety of surgical interventions depending on the severity of the injury. The most common of these procedures are: osteochondral autograft transplantation (OATS), autologous chondrocyte implantation (ACI) and microfracture. The rehabilitation outlined in this article is specific to the exact surgical procedure performed and the location in the knee. The outcomes of these procedures are also discussed.
