title: Surgical approaches for total knee arthroplasty.
abstract: There are various surgical approaches to the knee joint and its surrounding structures and such approaches are generally designed to allow the best access to an area of pathology whilst safeguarding important surrounding structures. Controversy currently surrounds the optimal surgical approach for total knee arthroplasty (TKA). The medial parapatellar arthrotomy, or anteromedial approach, has been the most used and has been regarded as the standard approach for exposure of the knee joint. It provides extensive exposure and is useful for open anterior cruciate ligament reconstruction, total knee replacement, and fixation of intra-articular fractures. Because this approach has been implicated in compromise of the patellar circulation, some authors have advocated the subvastus, midvastus, and trivector approaches for exposure of the knee joint. While these approaches expose the knee from the medial side, the anterolateral approach exposes the knee joint from the lateral side. With careful planning and arthrotomy selection, the anterior aspect of the joint can be adequately exposed for TKA in different clinical scenarios.
