Total knee arthroplasty (TKA) has been shown to have excellent long-term outcomes and survivorship in numerous studies, however, with changes in patient demographics, questions have arisen about the use of conventional arthroplasties and their functionality in highly active, young patients. The recent interest in bicruciate-retaining prostheses is aimed to address the need for an implant that can mimic a natural knee during high activity levels. Although there are currently few of these prostheses which are being utilized, results from prior studies have demonstrated similar results to that of anterior cruciate ligament-sacrificing TKA in terms of function and survivorship. In this review, we will describe the history, kinematics, clinical outcomes, concerns, and future outlook of bicruciate-retaining arthroplasty.
