There are a variety of operative and non operative modalities that can be used to address patellofemoral pain secondary to arthrosis. Patellofemoral Arthroplasty (PFA) is one of the latest alternatives designed to address the pain caused by severe, isolated osteoarthritis (OA) of the patellofemoral joint (PFJ). in the past, PFA has experienced variable success rates, and as a result many surgeons prefer Total Knee Arthroplasty. Arthrosurface, Inc. (Patellofemoral HemiCAP) has developed a new, minimally invasive, anatomic resurfacing technique with advantages to the performance of the traditional PFA components that may provide more consistent success rates. this paper outlines the surgical procedure for the patellofemoral HemiCAP for isolated PF arthrosis.
