A magnetic resonance imaging test was performed on a 56-year-old male patient, who visited with a one-month history of painless swelling at the popliteal area of the left knee. A popliteal cyst and non-calcified loose body in the cyst were identified. Synovial chondromatosis was diagnosed from a histology examination by excision and biopsy. This paper reports this case of extra-articular synovial chondromatosis of the knee with a review of the relevant literature.

Synovial condromatosis of the temporomandibular joint (TMJ) is characterized by the presence of loose bodies (joint mices). It can be confused with temporomandibular disorder clinically, and be with chondrosarcoma histologically. The purpose of this clinical report was to review the clinical, radiological, arthroscopic findings, histological feature and the results of surgical treatment of TMJ synovial chondromatosis. Four patients presented with pain of TMJ and limited mouth opening. The dynamic magnetic resonance imaging (MRI) disclosed a characteristic morphologic changes and displacement of the meniscus with limited translation of the condyle head. Bone scans showed progressive resorptive changes with hot-uptake of the radioisotope. The synovial loose bodies in the joint spaces were removed and sent to pathology for diagnosis as the synovial chondromatosis. The follow-up examination with computed tomography (CT) and MRI revealed no evidence of recurrence and good in function until postoperative 18 months. Diagnostically, the distension of the lateral capsule and fluid findings in the joint on the MRI are very suggestive tool for this synovial chondromatosis, but they are not always detected on the preoperative MRI. Arthroscopic approaches are very useful to inspect the joint spaces and to remove the loose bodies without interruption of the whole synovial membranes.

Synovial chondromatosis developes by metaplasia of synovial cell into chondroblast in synovium of joint. It most commonly involves large joints such as knee or hip, and rarely occurs in shoulder joint. It is often difficult to be diagnosed preoperatively and surgical synovectomy is known to be effective treatment. We encountered a case of synovial chondromatosis with hyaline cartilage forming loose body in subacromial and subdeltoid synovium on the shoulder of a 44-year old female suffered by pain and discomfort. The authors report this case with a review of the relevant literature.

Purpose: We evaluated the results of treatment and clinical symptoms of 11 cases of synovial chondromatosis in the ankle joint. Material and Method: From February 2001 to May 2008, 11 cases with synovial chondromatosis involving ankle joint underwent surgical treatment. There were 5 males and 6 females. The average age at surgery was 51 years. The average follow-up period was 42 months. Duration from onset of symptom to treatment was 117 months. Chief complaints of patients, 9 cases were pain and 1 case was mass like lesion, 1 case was found on x-ray. Preoperatively, all cases were evaluated on simple x-ray, 4 cases on CT, 4 cases on MRI and 1 case on ultrasonogram. 10 cases underwent synovectomy and loose body removal. 5 cases of 10 cases underwent open synovectomy and loose body removal and arthrosocpic surgery. 4 cases of 10 cases underwent only open synovectomy and loose body removal and 1 case of 10 cases underwent only arthroscopic surgery. 1 case underwent tibiotalar arthrodesis. Results: The location of loose bodies was 7 cases on posterior and 4 cases on anterior and 4 case on lateral and 3 cases on multiple site. Postoperatively, all patients showed marked clinical improvement and had subjective satisfaction except reoperation 2 cases and arthrodesis 1 case. AOFAS score of all patients was average 82.2. Conclusion: Clinical results of the synovial chondromatosis of ankle joint were satisfactory. More accurate preoperative evaluation is required to achieve prevention of postoperative recurrence and better outcome.

Synovial chondromatosis is a benign nodular cartilaginous proliferation arising in the synovium of joints. The radiolographic features of this condition are variable. Rarely, it would be confused with malignancy such as chondrosarcoma, osteosarcoma or synovial sarcoma. We report a case of primary synovial chondromatosis of the posterior aspect of the proximal tibia mimicking a parosteal osteoarcoma on the radiography, which showed a homogeneously radiopaque juxtacortical mass. However, subsequent computed tomography (CT) showed multiple intra-articular masses containing chondroid mineralization, suggesting synovial chondromatosis.

Synovial chondromatosis is an uncommon disorder characterized by metaplastic formation of multiple cartilaginous and osteocartilaginous nodules within connective tissue of the synovial membrane of joints. Osteochondroma is a benign lesion of osseous and cartilagenous origin. It is frequently found in the general skeleton, but is rare in the mandibular condyle. We experienced 2 patients with abnormal appearance of temporomandibular joint. Histologic diagnoses were not obtained, because surgery was unwarranted in view of the lack of symptoms and the benign differential diagnosis. We describes 2 cases that show the characteristics of both disease simultaneously.

Synovial chondromatosis is an uncommon disease of cartilage transformation of synovial membrane with formation of loose bodies within the joint space. The involvement of temporomandibular joint is very rare. Symtoms include swelling, pain, stiffness of the jaw, and inability to close the jaw. A case involving the temporomandibular joint(TMJ) and non-symptoms is presented.

Synovial chondromatosis (SC) is an uncommon progressive cartilaginous metaplasia of residual mesenchymal cells in synovial tissue. This disorder usually affects large joints and is rarely observed in the temporomandibular joint (TMJ). SC in TMJ is difficult to diagnose early owing to non-specific clinical symptoms. In this article, we report a patient with SC on the right TMJ, who presented with pain in the right TMJ and progressive occlusal changes, not responsive to conventional conservative temporomandibular disorder treatment for several months. This case emphasizes the importance of an accurate specific diagnosis for TMJ problems before the delivery of any treatment.

Synovial chondromatosis is an uncommon condition, and the involvement of the shoulder joint is rare. A 15 year old female patient presented to author's institution for right shoulder pain. We checked the plain radiographs and MRI. And they showed that a diagnosis of synovial chondromatosis in the shoulder, and they also demonstrated that the disease involved the bicipital tendon sheath as well as glenohumeral joint. We removed all loose bodies with total synovectomy by arthroscopic procedure, and a miniopen procedure for the lesions of biceps tendon sheath. Arthroscopic treatment affords excellent visualization of the shoulder joint with less morbidity. However, with current arthroscopic techniques, it is difficult to manage the synovial chondromatosis of biceps tendon in bicipital groove. The authors suggest that the complete elimination of synovial chondromatosis involving shoulder requires a mini-open procedure for the lesions of biceps tendon sheath in addition to the arthroscopic resection of the affected synovium and loose body removal in the glenohumeral joint.

Osteoarthritis is a noninflammatory degenerative disease affecting the articular surfaces and is accompanied by remodeling of the underlying bone. The sympotms of osteoarthritis of the temporomandibular joint are pain in the joint and muscles of mastication, limitation. Osteoarthritis is generally accepted that several factors can contribute to the trauma, aging process, internal derangement and MPDS. Radiographic features of the osteoarthritis are seen flattening of joint, sclerosis on flattened area and osteophyte or anterior lipping. In the past, osteoarthritis was considered to self-limiting disease. Currently, synovial chondromembrane is part of the process of osteoarthritis secondary to trauma. Synovial chondromatosis is an uncommon disease of cartilaginous transformation of synovial membrane with formation of loose bodies within the joint space. The pathogenesis is more an active metaplastic than a neoplastic process. The cause of synovial chondromatosis is unknown. Although trauma and inflammation have all been cited as possible factors in tis pathogenesis. The clinical sign and symptoms are unilateral swelling of the joint region, pain in the joint area and crepitus seem to be the most reliable signs and symptoms. Radiographic evidence of loose bodies may or may not be present. This is a case report of 66 year old female with synovial chondromatosis, that is advanced disease of the osteoarthrits. We treated patient with surgical excision of lose bodies, diskectomy and synovectomy. The defected articular fossa area was reconstructed with temporalis fascia flap. The result was satisfactory.
