Arthroscopy in primary synovial chondromatosis of the hip: description and outcome of treatment

Abstract

Between 1985 and 2000, 120 patients underwent arthroscopic management for primary synovial chondromatosis of the hip. We report the outcome of 111 patients with a mean follow-up of 78.6 months (12 to 196). More than one arthroscopy was required in 23 patients (20.7%), and 42 patients (37.8%) went on to require open surgery. Outcomes were evaluated in greater detail in 69 patients (62.2%) treated with arthroscopy alone, of whom 51 (45.9%) required no further treatment and 18 (16.2%) required further arthroscopies. Of the 111 patients, 63 (56.7%) had excellent or good outcomes. At the most recent follow-up, 22 patients (19.8%) had undergone total hip replacement. Hip arthroscopy proved beneficial for patients diagnosed with primary synovial chondromatosis of the hip, providing good or excellent outcomes in more than half the cases.
