Condromatosis sinovial de cadera: Tratamiento artroscópico

Background:  Synovial chondromatosis is defined as a benign metaplastic lesion, with a low incidence in hips. The ideal treatment technique is controversial due to the probable recurrence and degenerative progression described with both arthroscopic and open surgery. The aim of this study is to report the surgical technique and short-term results in a series of patients with synovial chondromatosis treated with arthroscopic hip. Methods:­  From April 2007 to May 2011, 10 patients (9 women and a man; average age 38 years; range 17-53) underwent hip arthroscopy for synovial chondromatosis. Surgical technique, clinical and radiological results, and satisfaction with the procedure were evaluated. The preoperative modified Harris hip functional scale was 51 points (range 49-54). Delayed histology confirmed diagnosis in all cases. Prospective follow-up averaged 35 months (range 24-47). Results: ­ The conventional arthroscopic technique to extract loose bodies and partial anterolateral synovectomy were performed in all patients. In three patients incision of one of the portals was extended to extract bodies of large diameter. The postoperative modified Harris hip functional scale averaged 88 points (range 85-91). No radiographic joint degenerative progress was seen at the last control. All patients were satisfied with the procedure. There were no complications. Conclusions:­  Favorable short-term results are consistent with those reported in the literature. Patients with synovial chondromatosis can be treated with hip arthroscopy safely and effectively.
