x ray report:
FINDINGS: Left knee: There are postoperative changes of anterior cruciate ligament reconstruction. The hardware is intact. There is a left knee effusion, but there is no acute fracture or dislocation. The left knee alignment appears normal. Right knee: Frontal only views of the right knee are unremarkable. IMPRESSION: Postoperative changes of anterior cruciate ligament reconstruction. No acute osseous abnormality.

x ray report:
FINDINGS:       Dedicated views of the right knee demonstrate tricompartmental      osteoarthritis most significant in the medial compartment where there      is near complete loss of joint space, osteophyte formation, and      subchondral cystic change. A small knee joint effusion is present.      There is normal alignment of the patella. Chondrocalcinosis is also      noted. There is prepatellar soft tissue swelling.           Dedicated views of the left knee demonstrate patellofemoral      predominant tricompartmental osteoarthritis, with joint space loss      ossified formation and subchondral sclerosis. A knee joint effusion      is present. There is prepatellar soft tissue swelling.           IMPRESSION:      1. Moderate to severe medial compartment predominant osteoarthritis      of the right knee.     2. Moderate patellofemoral compartment predominant osteoarthritis of      the left knee.
