Baker's cyst with extra‐ and intra‐articular synovial chondromatosis of knee: A case report

Abstract

Synovial chondromatosis is a rare benign condition characterized by chondral proliferation from synovium forming loose bodies which can occur extra‐articularly and intra‐articularly. Surgical removal remains the mainstay of treatment for synovial chondromatosis. Due to the risk of recurrence, every case must be followed up with an MRI.

“…Surgical removal of calcified bodies is indicated in the presence of mechanical symptoms like locking. The diagnosis can be confirmed with histopathological features such as papillary hyperplasia of the synovium and multiple cartilaginous nodules of varying size with or without focal ossification 3–5. Definitive treatment is with total joint arthroplasty 1–5 7.…”

“…Osteochondromatosis has a favourable prognosis. Potential complications of the osteochondromatosis include secondary osteoarthritis, recurrence and malignant transformation 1–7. Recurrence rate after definitive surgery is less than 10% 1.…”

“…Synovial chondromatosis is a rare condition characterised by the development of foci of cartilage in the joint synovium and less often in tendon sheaths or bursae. [1][2][3][4][5] Osteochondromatosis refers to when these cartilaginous foci are calcified. [1][2][3][4][5] The condition usually presents in patients between 30 and 50 years of age.…”
