Arthroscopy has advanced considerably in recent years, but is not often used for the hip. This is probably because of the shape and depth of the joint and the relatively small size of its capsule. We report our experience in the last four years, and in particular a successful arthroscopic...

Synovial tissue that lines joint cavities, bursae, and tendinous sheaths is generally too thin to be shown on MRI. However, as synovial tissue thickens...

Conclusions The clinical and imaging findings, along with potential differential diagnoses, are described. Since this condition tends to be progressive but self-limiting, indications for surgery depend on the level of symptomatic presentation in addition to...

We report the results of arthroscopic removal of loose bodies and abnormal synovium from 18 knees with primary synovial chondromatosis. After a mean of three years, six months (range one to 10 years), 14 knees were either symptom-free or had only minor symptoms. Three of these had required two arthroscopic...

In synovial chondromatosis, foci of metaplastic cartilage form in the synovial membrane of a joint. These foci may grow, become detached from the synovial membrane and enter the joint cavity as loose bodies. Calcification or ossification of the cartilage masses may occur. As far as we know no cases of...

We describe a case of primary articular synovial chondromatosis in a metacarpophalangeal (MCP) joint of a 48-year-old male. The patient initially presented with MCP joint swelling and pain with normal plain radiographs. Following a fourteen month course of conservative management, surgical debridement of the joint revealed multiple loose bodies consistent...

Synovial chondromatosis is the rare and benign metaplasia of the synovial membrane resulting in the formation of multiple intra-articular cartilaginous bodies. Synovial chondromatosis is known by several other names including articular chondrosis and synovial chondrosis. This self-limited and non-aggressive condition occurs most commonly in the knee followed by the...

The pain, swelling, and mechanical symptoms of synovial chondromatosis and its generation of loose bodies have historically been treated with surgery. Since the mid 1950s, the technical strategy has included open arthrotomy with removal of loose bodies and synovectomy. Controversy exists regarding the utility of synovectomy. Some authors prefer simple...

Primary synovial chondromatosis is an uncommon disorder, and involvement of the hip joint is rare. The clinical symptoms are usually non-specific, and a clinical diagnosis of synovial chondromatosis of the hip may be difficult and delayed, especially before the ossifying nodules become evident. Loose bodies in the joint can cause...

Discussion: - a monarticular synovial proliferative disease which is characterized by the metaplastic conversion of cartilagenous tissue to ossified loose bodies; - cartilagenous or osteocartilaginous metaplasia takes place w/in the synovial ...

multiple ossified synovial fragments within joint space ("joint mice")
synovial villus thickening

--> bone formation

familial
  myriad very small densities
  presents early in life
non-familial
  several small + large densities
  presents later

We report four patients who showed hundreds of brilliant white loose bodies at arthroscopy of the knee after a short history of pain and crepitus. Histological, historical and clinical evidence is presented which indicates that the aetiology of this condition is the culture of chondrocytes in synovial fluid. It is...
