Is Patellofemoral Osteoarthritis Common in Middle‐Aged People With Chronic Patellofemoral Pain?

Factors that predict a poor outcome 5–8 years after the diagnosis of patellofemoral pain: a multicentre observational analysis

“…While our findings do not support the proposition that long-term PFP necessarily leads to PFOA,16 17 19 the radiographic criteria used may have been suboptimal for this population. In this relatively young PFP cohort (age range at baseline 14–40 years), X-ray cannot detect early OA changes.…”

Is patellofemoral osteoarthritis a common sequela of patellofemoral pain?

“…Also, Farrokhi et al 21 identified elevated patellofemoral stress in people with PFP, a potential mechanism underpinning a link between PFP and structural joint disease. Further evidence for this link may come from our evaluation of adults aged >40 years with chronic PFP, where radiographic PFOA was present in 69% of people, and was more prevalent than tibiofemoral OA (45%) 22. Thus, the best available evidence suggests that PFP and PFOA exist along a continuum of disease.…”

Magnetic Resonance Imaging of the Extensor Mechanism

“…60 Although osteoarthritis more frequently affects older patients, young patients may also present with osteoarthritis in the setting of prior trauma, participation in high-impact sports, or previous patellar dislocation. MR findings manifest as Fig.…”
