[Generalised Form of Synovial Chondromatosis of the Knee Joint].

UNLABELLED: This study describes a diagnostic and therapeutic algorithm in a 53-year-old male patient who was diagnosed with a synovial chondromatosis of the knee joint extending to the popliteal fossa and soft tissues around the knee. Because of the presence of massive nodules, the patient was indicated for total synovectomy, with removal of pathologically changed cartilaginous tissue, performed by combined anterior and posterior approaches to the knee joint. Despite complete removal of the synovium and loose cartilage bodies and the patient's pain relief in the post-operative time, three years after the operation new problems appeared. Magnetic resonance imaging (MRI) confirmed a relapse of synovial chondromatosis and the patient was indicated for revision surgery of the knee joint. The results of physical examination and MRI scans, and intra-operative findings in the patient are reported.

KEY WORDS: synovial chondromatosis, total synovectomy, direct anterior and posterior approaches to the knee joint.
