SD standard deviation; Clinical diagnoses are composite diagnoses made by physicians using both musculoskeletal examination and imaging; Others knee diagnoses included: contusion of the tibial plateau (n = 2), PCL tear (n = 1), soleus tear (n = 1), psychosomatic origin (n = 1), muscular spasms linked to multiple sclerosis (n = 1), hamstring tendinopathy (n = 3), medial collateral ligament injury (n = 1), functional instability without meniscal or ACL injury (n = 1); Imaging diagnoses are based on imaging studies using radiograph or magnetic resonance imaging; Grades are for Kellgren-Lawrence scale in the most affected compartment; Radiographic OA was defined as K-L≥ 1
