Predictors of pain and cartilage damage in patellofemoral joint osteoarthritis: stair descent knee kinematics and kinetics.

ABSTRACT:

Objective

To identify gait biomechanical characteristics associated with pain and cartilage damage in individuals with patellofemoral joint osteoarthritis (PFJ OA) during a stair descent activity.

Design

Cross-sectional observational study.

Setting

University-based motion analysis laboratory and musculoskeletal imaging centre.

Participants

83 participants entered the study; 66 participants (41 female, 25 male) completed all components required for this analysis. Participants were recruited via electronic health records following clinical knee MRI. Inclusion criteria included MRI-confirmed patellofemoral cartilage lesions using Whole Organ MRI Score (WORMS) gradings (WORMS >1), pain during stair ambulation, body mass index (BMI) ≤35 and informed consent.
