Objective: The objective of this study was to assess, with knee radiography, joint space narrowing (JSN) and its relationship to meniscal tears, anterior cruciate ligament (ACL) ruptures, articular cartilage erosion, and duration of pain in patients with knee osteoarthritis. Materials and methods: A total of 140 patients who had knee osteoarthritis and underwent primary total knee replacement (TKR) surgery, with unicompartmental medial tibiofemoral JSN (grade 1 or greater) and normal lateral compartments, were recruited. Polytomous logistic regression was used to assess the relationship between JSN and risk factors. Results: All patients with JSN were categorized as grade 1 (n=14, 10.0%), grade 2 (n=64, 45.7%), or grade 3 (n=62, 44.3%). Women presented with indications for a TKR at a younger age than men (mean age, 69 vs 73 years, P
