Associations of foot and ankle characteristics with knee symptoms and function in individuals with patellofemoral osteoarthritis

Background Foot and ankle characteristics are associated with patellofemoral pain (PFP) and may also relate to patellofemoral osteoarthritis (PFOA). A greater understanding of these characteristics and PFOA, could help to identify effective targeted treatments. Objectives To determine whether foot a...

Description
Summary:Background Foot and ankle characteristics are associated with patellofemoral pain (PFP) and may also relate to patellofemoral osteoarthritis (PFOA). A greater understanding of these characteristics and PFOA, could help to identify effective targeted treatments. Objectives To determine whether foot and ankle characteristics are associated with knee symptoms and function in individuals with PFOA. Methods For this cross‐sectional study we measured weightbearing ankle dorsiflexion range of motion, foot posture (via the Foot Posture Index [FPI]), and midfoot mobility (via the Foot Measurement Platform), and obtained patient‐reported outcomes for knee symptoms and function (100 mm visual analogue scales, Anterior Knee Pain Scale [AKPS], Knee injury and Osteoarthritis Outcome Score, repeated single step‐ups and double‐leg sit‐to‐stand to knee pain onset). Pearson's r with significance set at p
