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: To purpose of this study was to review the long-term follow up results of surgical treatment of the localized pigmented villonodular synovitis in the knee. Materials and Methods: We evaluated and analyzed 6 patients (6 cases) who underwent arthroscopy and excisional biopsy as pigmented villonodular synovitis from March 1988 to June 2002. The clinical diagnosis was confirmed by pathologic findings. All patients had been managed with arthroscopic excision, but two patients underwent mini-open excision. The recurrence was evaluated by the loss of preoperative symptom and physical examination for range of motion, pain and finding of swelling. Results: According to the arthroscopic findings, all patients had localized form of pigmented villonodular synovitis. Three patients had pedunculated type (one of them had torsion) and the two patients had nodular type and one patient had mixed type. All patients had improvement in pain, swelling and range of motion and there was no evidence of recurrence. Conclusion: In terms of long term follow up results, precise preoperative diagnosis and the adequate surgical treatment, especially arthroscopic excision for the localized pigmented villonodular synovitis, would be considered one of the fundamental modality to expect the good results.

Purpose : To validate the arthroscopic synovectomy for the treatment of hemophilic knee. Materials and Methods: From January 1996 to January 2001, 28 arthroscopic synovectolny were performed in 26 patients with hemophilic arthropathy of the knee. The mean age was 17.8 years. The mean follow-up period was 3 years 11 months. We used six portals (two anterior, two suprapatellar and two posterior) and posterior trans-septal portal in all cases. Result : The mean frequency of hemarthrosis was 4 times per month preoperatively and 2 postoperatively. The mean amount of factor replacement was 4,633 units preoperatively and 1,505 postoperatively. The mean range of motion was $112^{\circ}$ preoperatively and $107^{\circ}$ postoperatively. On radiographic evaluation, three cases were progressed at the latest follow-up. On the subjective evaluation, significant or moderate improvement were in 19 cases $(68\%)$, and no improvement or deterioration in 9 cases $(32\%)$. Conclusion : With complete synovectomy through the appropriate arthroscopic portals, arthroscopic synovectomy of the knee in hemophilic patients is the successful method in decreasing bleeding episodes, amount of factor replacement, knee pain and preventing or delaying onset of end-stage hemophilic arthropathy.

Purpose : To analyze the result of arthroscopic synovectomy of the shoulder for rheumatoid arthritis. Material and Method : Sixteen patients were treated from May, 1998 to December, 2002 who undergone arthroscopic synocvectomy of the shoulder for rheumatoid arthritis. The study group constisted 2 men and 14 women. the age at surgery ranged from 32 to 66 years, with average of 50 years. The result were analyzed using the clinical assessment of shoulder surgery classification system issued by the Japanese Orthopaedic Association and subjective satisfactation of the patients cartegorized excellent, good, poor. Results : The mean score of ROM was increased from 13.9 preoperative to 23.8 postoperative and the mean score of pain was inclosed from 22.0 preoperative to 26.5 postoperative. The result of subjective satisfaction were 7 excellent, 7 good,2 unsatisfied, so forteen cases $(88\%)$ above the good. Conclusions : The shorter morbidity date, and the letter damage of articular cartillage, the better results of the arthroscopic synocvectomy of the shoulder for rheumatoid arthritis.

Purpose: The purpose of this study was to suggest a multimodal diagnostic approach to determine the cause of the disease in patients diagnosed with synovitis of the wrist and who underwent synovectomy. Materials and Methods: Twenty-nine patients, who underwent contrast magnetic resonance imaging (MRI) preoperatively and synovectomy from January 2000 to December 2013, were reviewed retrospectively. Among them, 17 patients underwent a $Tc^{99m}$ white blood cell (WBC) scan preoperatively. In patients who met the diagnostic criteria of rheumatoid arthritis (RA), the diagnosis was confirmed as RA if the MRI finding or histology was compatible with RA. If the MRI finding and histology were disparate, the final diagnosis was made based on the histologic finding. Results: Of the nine patients who met the diagnostic criteria of RA, seven patients were finally diagnosed as RA and two patients as tuberculous arthritis. Of the 20 patients who did not meet the diagnostic criteria of RA, the MRI findings and histology were consistent with the same disease in 12 patients. In the remaining eight patients, five were diagnosed with nonspecific chronic synovitis, one with RA, and two with tuberculous arthritis based on the clinical findings, MRI, and histology findings. Conclusion: MRI and a WBC scan are very useful imaging modalities for diagnosing the causative condition of the wrist synovitis. A histology evaluation after synovectomy can also be useful in cases with a difficult diagnosis or are refractory to medications.

Extraarticular synovial chondromatosis is a very rare disease which affects the hands, feet, and wrists most commonly. In cases of involvement around large joints, the tissues around knee are usually involved. It arises from tendon sheath, capsular tissue and bursae. It is an idiopathic process in which the synovial cells undergo the metaplasia into cartilage cells. Chondroid matrix of the cartilaginous nodules calcify and ossify to be the osteochondroma. On simple radiograms before calcification and/or ossification of the chondroid tissues the cartilaginous nodules look normal on radiograms. Therefore MRI is needed to establish the diagnosis. We report a case of extraarticular pan-peri-meniscal synovial chondroma around right knee, initially suspected as a ganglion cyst which clinically mimicked a large rounded lesion or a cystic lesion on MRI.
