Round # 17
The patient is a 75 y.o. man with a history of end-stage left hip osteoarthritis who underwent total hip arthroplasty 7 years prior to his visit who returns today for follow-up. His overall health has been quite good, but he describes some mild recent-onset discomfort in the left groin region that is slightly worse with weight-bearing and is relieved with rest. He denies any fevers, chills, night sweats, skin rashes, or other systemic symptoms. On examination, he has mild limitation of motion on external rotation of the left hip, but no evidence of peripheral synovitis or bursitis. Hip radiographs are promptly obtained and are compared to his baseline films from several years ago
