Johnson VL, et al. - Researchers intended to determine if there is an association between a tear of the anterior cruciate ligament (ACL) with knee symptoms and radiographic osteoarthritis (OA). A within-person, between-knee cross-sectional study of 37 candidates from the Osteoarthritis Initiative with a complete or partial ACL tear detected on MRI in 1 knee (index knee) were involved. According to findings, individuals with their ACL deficient knee did not report a rise in knee pain, stiffness or impairment. The only disability in ACL-deficient knees was linked to the worsening severity of radiographic OA.
