  2. †Right leg in references used for comparison with patients’ affected and non-affected legs.
  3. ‡Could not perform the test: Total OA group: affected leg n = 33, non-affected leg n = 15; Hip OA: affected leg n = 9, non-affected leg n = 4; Knee OA: affected leg n = 24, non-affected leg n = 11.
  4. Ext = extension strength.
  5. CI = confidence interval. Confidence intervals not containing zero indicate statistical significance.
