Identification and management of patients with isolated patellofemoral osteoarthritis are challenging. Many of these patients present at a young age and it is important to distinguish degenerative change in the patellofemoral articulation from the other various causes of anterior knee pain. Once the diagnosis of isolated patellofemoral arthrosis has been made non-operative and conservative surg...

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 surgeo...

More than 70% of osteochondritis dissecans (OCD) lesions in the knee joint occur on the posterolateral surface of the medial femoral condyle, designated as the classic area. Approximately 15–20 % of OCD lesions in the knee joint occur in the inferior–central part of the lateral femoral condyle, and 1 % or less occur on the patellofemoral joint surface [1, 2]. We encountered a patient who simult...

OBJECTIVE To determine the differences in load-bearing patellofemoral joint cartilage thickness between genders. To determine the differences in load-bearing cartilage thickness between pain-free controls and individuals with patellofemoral pain. METHODS The articular cartilage thickness of the patella and anterior femur was estimated from magnetic resonance images in 16 young, pain-free cont...

Because we communicate mainly through words, it is important that terms be understood in the same manner by all readers. Unfortunately, the study of the patellofemoral joint is complicated by the use of expressions that hold different meanings for different readers. Ideally, the community of musculoskeletal physicians should agree on a single definition of terms, but until then, authors and spe...

Patellofemoral joint degeneration is often considered a contraindication to medial unicompartmental knee replacement. We examined the validity of this preconception using information gathered prospectively on the intra-operative status of the patellofemoral joint in 824 knees in 793 consecutive patients who underwent Oxford unicondylar knee replacement for anteromedial osteoarthritis. All opera...

STUDY DESIGN Controlled laboratory study using a cross-sectional design. OBJECTIVES To compare patellofemoral joint kinematics, femoral rotation, and patella rotation between females with patellofemoral pain (PFP) and pain-free controls using weight-bearing kinematic magnetic resonance imaging. BACKGROUND Recently, it has been recognized that patellofemoral malalignment may be the result of...

computer model of the patellofemoral joint was developed and the effects on the anterior displacement of the tibial tuberosity were investigated. the input geometrical and verification data for the model were obtained form an experimental study on a cadaver knee, mounted in an instron machine. the computer program found the configuration of the patellofemoral joint which satified both the geome...
