Patellofemoral arthritis is diagnosed when there is significant loss of cartilage from the joint surface of the patella and the trochlea (the groove in the femur where the kneecap rests). The diagnosis is restricted to arthritis seen only in this compartment of the knee.

Patellofemoral osteoarthritis (PFJ OA) describes cartilage degeneration isolated to structures within the PF joint (PFJ), specifically the trochlear groove and underside of the patella. It can be developed primarily or post-traumatically.

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.

The patellofemoral joint is a unique and complex structure consisting of static elements (bones and ligaments) and dynamic elements (neuromuscular system). [4] . The patella has a configuration of a triangle with its apex directed inferiorly.

2024年12月19日 · Patellofemoral joint (PFJ) diseases are chronic degenerative conditions that contribute to knee joint symptoms. Unicompartmental knee arthroplasty (UKA) is widely regarded as an effective treatment for knee osteoarthritis (KOA); however, its specific indications remain a subject of debate.

2023年12月1日 · PFJ arthroplasty (PFJA) has many benefits including being less invasive, associated with lower blood loss, is more cost-effective, and leaves the kinematics of the tibiofemoral joint undisturbed. As a result, there are arguably better functional outcomes associated with PFJA, however the historical revision rate of this procedure is high.

2024年12月1日 · In this bilateral PET/MRI study of isolated PFJ-OA subjects, bone remodeling markers (SUV Mean and SUV Max) were positively associated with deep cartilage subregional T 1p and T 2 values; and negatively associated with superficial cartilage subregional T 1p and T 2 values in trochlear and patellar, medial, and lateral regions. In both lateral ...

Under this model, the goal of interventions for PFP should be to re-establish patellofemoral joint (PFJ) homeostasis through a temporary alteration of load to the offended tissue, followed by incrementally restoring the envelope of function to the baseline level or higher.

The patella-femoral joint (or PFJ) is the articulation of the kneecap on the femur (thigh bone). PFJ pain is an umbrella term relating to anterior knee pain due to irritation of the PFJ. This can be caused by a number of contributing factors.

A skyline view is most appropriate to best view the PFJ. The presence of osteophytes, as well as joint space narrowing, confirms the clinical findings for PF OA. X-rays can be used to interpret the morphology of the PFJ such as the shape of the trochlear where a shallow trochlear has been associated with PF OA. MRI [edit | edit source]
