Abstract
PurposeThis retrospective study summarized the clinical, radiographic, and arthroscopic manifestation of synovial chondromatosis (SC) of the hip, along with the post-operative effect to discuss the curative effect of arthroscopic management of hip SC.MethodsTwenty-one patients who underwent arthroscopic surgery from the same surgeon for hip SC were followed up for an average of 45 months. T-shaped capsulotomy was routinely performed in each case. Visual analog scale, range of motion, modified Harris Hip Score, and International Hip Outcome Tool score were collected preoperatively and at the time of the latest follow-up. All patients’ demographics, radiographs, and arthroscopic images were collected to summarize and conclude the similarities and differences of their manifestation.ResultsLarge wedged clumps of loose bodies demonstrated distinguishable radiographic, arthroscopic appearance and demanded a different surgical strategy. Postoperative scores were all significantly improved. One case of residual pain and two cases of residual loose bodies with no symptom related were reported at the final follow-up. All but one patient were satisfied with the outcome.ConclusionArthroscopy treatment of hip SC with T-shaped capsulotomy has demonstrated a good result in terms of clinical outcome score, recurrence rate, and complication rate. On the basis of this study, we concluded the clinical performance of large wedged clumps of loose bodies of hip SC.
Highlights
Synovial chondromatosis (SC) is a rare disease with cartilaginous metaplasia which occurs within the synovium of the joint [1, 2]
It commonly results in the growth of cartilaginous nodules in the synovium, many of which may detach and become loose bodies in the joint and subsequently cause damage to the articular surface and cause osteoarthritis [3]
The aim of this study was to report our own experience of arthroscopic management of hip SC in 21 patients in a retrospective way
Summary
Synovial chondromatosis (SC) is a rare disease with cartilaginous metaplasia which occurs within the synovium of the joint [1, 2]. It commonly results in the growth of cartilaginous nodules in the synovium, many of which may detach and become loose bodies in the joint and subsequently cause damage to the articular surface and cause osteoarthritis [3]. Due to the nonspecific and insidious symptom of the disease and regularly false-negative imaging in early stages, the period to confirm definitive diagnosis often exceeds more than 2 years. Plain radiograph was considered first-line imaging, due to its easy practicability, sensitivity for the most common
