Past medical history includes osteoarthritis, hypertension, and hyperlipidemia.  Medications include lisinopril and atorvastatin.  Surgical history includes appendectomy.  Family history is noncontributory.  Physical examination reveals tenderness to palpation along the medial and lateral joint lines of the right knee.  Positive McMurray's test suggests meniscal tear.  There is mild effusion and crepitus with range of motion.  Ligamentous testing is stable.  Radiographs of the right knee demonstrate mild degenerative joint disease.
