Association of knee joint performance and gait patterns with pain catastrophizing in patients with severe knee osteoarthritis: a cross-sectional study.

ABSTRACT:

Background

Pain catastrophizing is linked to patient-reported outcomes in knee osteoarthritis (OA) patients, but its correlation with objective joint-level function (range of motion and strength) and gait patterns is unclear. This study examined the association between objective knee function, gait patterns, and pain catastrophizing in severe knee OA patients.

Methods

This cross-sectional study included patients with knee OA admitted for total knee arthroplasty over a 3-year period from November 2016. Medical records and instrumentation databases were assessed. Patients who completed the Pain Catastrophizing Scale (PCS) were categorized into high PCS (scores ≥ 30) and low PCS (scores  RESULTS: The analysis included 63 patients with 75 knees divided into 60 knees in the high-
