Osteoarthritis of the Right Hip

Case Overview:

D.P. is a 53 year old male who presented with progressively worsening pain in his right groin. His pain had been present for over 2 years prior to consultation. D.P. is employed as a high school physical education teacher who enjoys coaching the varsity football team. In the past, he had been able to control a majority of his pain with non-steroidal anti-inflammatory medications and activity modifications. In recent months, D.P. noted the severity of the pain had increased to the point that he is having difficulty standing and walking for prolonged periods of time. Due to his current level of pain and dysfunction, he was no longer able to effectively perform duties as a teacher or a coach. He no longer was able to participate in many of his usual hobbies, including gardening and bowling. Within the few weeks prior to consultation, D.P.’s pain had progressed to the point of making it difficult to sleep comfortably.


Due to the patient’s progressive symptoms, clinical examination and radiographic examination, surgery was recommended. He subsequently underwent a total right hip arthroplasty. Because of his physiologic age, activity level and bone quality, a non-cemented femoral stem was used in conjunction with an oxynium femoral head articulating with a highly cross-linked polyethylene liner.


Since D.P.’s surgery, he has had a complete resolution of his arthritic pain. The patient has an antalgic gait and examination demonstrates a resolution of his Trendlenberg sign with symmetrical strength and ROM in his lower extremities. He no longer depends on anti-inflammatory medications and has been able to resume working and coaching full time without any discomfort. He has reconnected with his hobbies and has recently begun to loose weight with a guided exercise program. D.P. has recently characterized his total hip replacement as a “new lease on life.”

Clinical Overview:

The patient was referred by his primary physician to our physicians for further evaluation. Physical examination demonstrated a Trendlenberg gait and pain localized to the groin with full passive flexion and internal rotation. He also indicated some discomfort with a straight leg raise. AP and lateral radiographs of his hip demonstrated end stage osteoarthritis with extensive involvement of both the femoral head and acetabulum.
