She complained of left knee pain and stiffness for 3 years. a CR revealed narrowing of medial joint space and osteophytes; K-L grade 2 (red arrowed). b The calculated WOMAC index total score was 51. c Transverse plane MSK US of the left knee showed thinned medial femoral articular cartilage (arrowheads) (MC = 0.15 cm, IA = 0.35 cm, and LC = 0.18 cm). d A longitudinal scan along the MCL line revealed a medium-sized osteophyte projecting from left femoral condyle (white arrowed) and no medial meniscal extrusion (asterisk). Suprapatellar small amounts of joint effusion were also observed
