Objective The aim of this work was to study the correlation between health-related quality of life and performance-related measures in Egyptian patients with primary knee osteoarthritis (OA). Patients and methods One hundred patients with primary knee OA who were attending the outpatient clinic of the hospital were included in the study. All patients had bilateral medial tibiofemoral knee OA. Radiological severity of the disease was evaluated with the Kellgren–Lawrence scale. All patients completed Knee Injury and Osteoarthritis Outcome Score (KOOS); that is a knee-related disorder-specific questionnaire for the assessment of quality of life. The Timed Up and Go test was used for the evaluation of performance-based functional status. Results Eighty-eight (88%) patients were female. The mean age was 57.30±6.37 (50–75) years, and the mean BMI was 36.83±5.37% kg/m2. The mean symptom duration was 8.76±4.71 years. The mean radiological stage was 2.88±0.82. There was a statistically significant negative correlation between all of the KOOS domains and Timed Up and Go (P≤0.01). Conclusion KOOS is not only a good indicator of physical performance in patients with knee OA but also provides information about the impact of knee-related disability on the quality of life and recreational activities.
