Osteoarthritis (OA) of the knee is a commonly diagnosed condition with up to 25% of people having signs of Patellofemoral (PF) OA and up to 40% of these people have isolated PF OA [1].

Early PFJ OA with mechanical symptoms or significant activity limitation is often first addressed by surgical debridement, removal of loose bodies, and chondroplasty to help improve the longevity of the native patellofemoral joint and function.

Patellofemoral arthritis affects the underside of the patella (kneecap) and the channel-like groove in the femur (thighbone) that the patella rests in. It causes pain in the front of your knee and can make it difficult to kneel, squat, and climb and descend (go down) stairs.

它是内侧或外侧间室OA演变的一部分，冠状面力线异常导致内侧或外侧髌骨高压，最终形成PFOA； 通常引起轻微的髌股症状，它与冠状位力线不良相关，临床检查和PFJ影像学发现之间无相关性； UKA通过治疗股胫关节OA，纠正髌股关节力线显著改善患者的临床疗效。

The patellofemoral joint (PFJ) is one compartment of the knee that is frequently affected by osteoarthritis (OA) and is a potent source of OA symptoms. However, there is a dearth of evidence for compartment-specific treatments for PFJ OA.

The algorithm for the surgical treatment of PFJ OA can begin with arthroscopic assessment of the PF articular cartilage to address mechanical symptoms and to evaluate/treat lateral soft tissue with or without overhanging lateral osteophytes.

2008年9月16日 · Physiotherapy treatment will consist of (i) quadriceps muscle retraining; (ii) quadriceps and hip muscle strengthening; (iii) patellar taping; (iv) manual PFJ and soft tissue mobilisation; and (v) OA education. Resistance and dosage of exercises will be tailored to the participant's functional level and clinical state.

This review summarises the evidence suggesting why PFJ OA should be considered a distinct clinical entity and how it may best be managed using conservative, non-pharmacological treatment approaches that are targeted to the PFJ.

2020年5月1日 · Patellofemoral joint (PFJ) osteoarthritis (OA) is identified on radiographs as osteophytes and loss of articular cartilage on patella or in the femoral trochlear groove [1]. PFJ OA is an important source of knee symptom after ACL injury.

The patellofemoral joint (PFJ) is an important source of symptoms in knee osteoarthritis (OA) compared to the tibiofemoral joint (TFJ). In symptomatic knee OA cohorts, the prevalence of radiographic PFJOA is 57% and in radiographic and symptomatic knee OA cohorts the prevalence of PFJOA is 43% [1].
