Synovial Chondromatosis of Knee Managed with Combined Arthroscopic and Limited Open Technique: A Case Report

Synovial chondromatosis is a condition affecting the synovium, leading to severe joint disability and dysfunction, with surgical management, either open or arthroscopic, being the primary treatment approach. We present a case of a 35-year-old male patient with a 12-month history of right knee pain and swelling who underwent arthroscopic excision of intra-articular loose bodies, combined with a limited open technique for extra-articular loose bodies and showed significant improvements immediately from postoperative day 1, including reduced knee joint volume and enhanced knee range of motion (0°-140°), with no recurrence noted at the 12-month follow-up. This case highlights the effectiveness of combining arthroscopy and mini-arthrotomy techniques for managing synovial chondromatosis, particularly in cases with large loose bodies, achieving favorable clinical and functional outcomes.
