Randomized Controlled Trial Comparative StudyAssociation of severity of coexisting patellofemoral disease with increased impairments and functional limitations in patients with knee osteoarthritis.
To evaluate the association between severity of coexisting patellofemoral (PF) disease with lower extremity impairments and functional limitations in patients with tibiofemoral (TF) osteoarthritis (OA). ⋯ It appears that knees with more severe coexisting PF disease demonstrate features distinct from those observed in TFOA in isolation or in combination with mild PF disease. Treatment strategies targeting the PF joint may be warranted to mitigate the specific lower extremity impairments and functional problems present in this patient population.
