ffects of Osteoarthritis and Fatigue on Proprioception of the nee

Objective: To evaluate the impact of knee osteoarthritis OA) and periarticular muscular fatigue on knee joint inesthesia. Design: Cross-sectional study. Setting: A physical medicine and rehabilitation outpatient linic. Participants: Fifty patients with bilateral OA of the knee, nd a control group of 30 age-matched healthy volunteers. Interventions: Not applicable. Main Outcome Measures: The Kellgren-Lawrence grading ystem was used to determine the radiographic severity of knee A. The Lequesne index of severity for knee osteoarthritis was sed for assessment of pain, kinesthesia was measured by etermining angle reposition error at the knee joint using sokinetic dynamometry, and muscle strength was measured by sokinetic dynamometry. Results: Reposition errors did not differ between the patient nd the control groups, nor did they differ between preand ostexercise. Conclusions: Mild-to-moderate OA of the knees does not ffect reposition error. Fatigue produced by mild-to-moderate xercise also has no effect on reposition error.
