A recent study outlines the vital part hip arthroscopy plays after a patient undergoes a hip resurfacing arthroplasty.
Here are seven facts to know:
1. A study recently showed 7 percent of 68 patients with an arthroscopy-confirmed diagnosis later being revised to total hip replacement, compared with almost 40 percent of patients who had no definite diagnoses before hip arthroscopy.
2. Omer Mei-Dan, MD, stated patients given a definitive diagnosis are successful and most patients with a severe metal-on-metal reaction will subsequently need total knee replacement. He provided these findings at the International Society for Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine Biennial Congress.
3. Patients in the study, comprised of mainly females, had an average age of 58 years with the mean time to arthroscopy after resurfacing being five years.
4. Researchers established a confirmed diagnosis addressed by arthroscopy with the majority of these patients having iliopsoas tendinosis or excessive metal wear.
5. Of the 41 patients, three patients did not improve because of their severe metallosis and thus were revised to a total hip replacement.
6. A second cohort of 27 patients did not have a definitive diagnosis established prior to arthroscopy.
7. Of these 27 patients, the majority had a synovial reaction and 10 had a failed arthroscopy, therefore undergoing THR.
