Pigmented villonodular synovitis(PVNS) is a benign proliferative lesion, involving synovial tissue in joints, tendon sheaths, and bursae. Pigmented villonodular synovitis is a rare and usually monoarticular condition and primarily affects the knee joint and hand. Polyarticular PVNS appears in less than 1% of all case and its occurrence in the shoulder is rare(<2%). We present a 64-year-old male who had pigmented villonodular synovitis of both shoulder joints, which was treated by arthroscopic total synovectomy.

Pigmented villonodular synovitis most commonly occurs in the knee joint and rarely extends into the popliteal space, which not only has mimicked Baker's cyst but also has been misdiagnosed as malignant tumor. We report a case of a diffuse pigmented villonodular synovitis of knee joint which is extended into the popliteal space as like a popliteal cyst. We treated this case by arthroscopic total synovectomy and excision of cyst. There was no recurrence during more than one year after operation.

Olecranon bursitis rarely Progresses to septic arthritis. In our case, the 24 year old woman was visited due to progressing right elbow pain, despite antibiotic treatment of chronic olecranon bursitis caused by elbow laceration 2 months ago. Pus draining sinus, localized heating and swelling could be seen on physical examination. Septic arthritis and pathologic fracture was diagnosed under arthroscopic examination. Arthroscopic irrigation and synovectomy for elbow joint, olecranon bursectomy and curettage of olecranon bone was done. In the operation field, the elbow and draining sinus over olecranon was communicated each other on saline irrigation test. The patient was treated for 3 weeks with intravenous antibiotics. At postoperative 4 weeks, bone graft was done. The possibility of chronic osteomyelitis and septic arthritis must be considered in a patient with chronic olecranon bursitis.

This is a report on a aseptic synovitis diagnosed and treated arthroscopically following the meniscal repair using biodegradable Meniscus Arrow$^{(R)}$(Bionix Inc, Malvern, USA). Histological examination revealed chronic nonspecific synovitis and birefringent material. Immunohistochemical tests were positive in lysozyme, ${\alpha}$-1-antitrypsin and ${\alpha}$-1-antichymotrypsin. The patient was received arthroscopic synovectomy, and then pain and swelling of the knee joint was relieved. Range of motion was improved to full range. As far as we know, this is the first case of aseptic synovitis after meniscal repair using biodegradable Meniscus Arrow$^{(R)}$.

Most pigmented villonodular synovitis (PVNS) is occurred in knee joint and finger of hand. PVNS is rarely occurred in shoulder joint. In English and French literatures, less than 30 cases were reported. We report 3 PVNS cases with rotator cuff tears, which was treated by arthroscoic extensive synovectomy, debridement and rotator cuff repair. The PVNS with rotator cuff tear in shoulder joint was rarely reported in the Korean literature.

Radiation therapy has been used for the cancer treatment and radiation synovectomy$\^$1-3)/. There are two kinds of radiation therapy; the external radiation therapy and the internal radiation therapy. Hitherto, the external radiation therapy has been widely used, but for the lack of its selectivity it requires strong radiation dose and causes the irritation and damage of the normal tissue or organ. Therefore many researchers give their interests to the internal radiation therapy in which the radioactive materials are injected directly into the target organ or tissue. Many ${\beta}$-emitting radionuclides have been studied for the application of the internal radiation theraily. Among them, Holmium-166 has the many beneficial physical characteristics for the internal radiation therapy such as appropriate half life (26.8hr), high ${\beta}$ energy (max. 1.85 MeV(51%), 1.77 MeV (48%), mean 0.67MeV), and low ${\gamma}$ energy (0.081MeV) easily detected by ${\gamma}$-camera. In the internal radiation therapy, the administered radioactive materials should be retained in the target long enough to increase the therapeutic effects and avoid the damage in the normal tissue or organ. For this purpose, radionuclides are used as complex form with carriers. Carriers should have a high affinity with radionuclides in vivo and in vitro, so the complex can be evenly distributed in the lesion but can not be leaked out from the lesion.

Diffuse pigmented villonodular synovitis (PVNS) involving ankle joint needs complete mass excision and total synovectomy to reduce recurrence rate, while surrounding ligaments can be easily damaged. So the concurrent ligament reconstruction should be considered for post-excisional instability in subtalar joint as well as lateral ankle joint. We describe our experience in the management of a diffuse type PVNS, invades lateral talocrural joint extended to subtalar joint and introduce a new technique of all-in-one reconstruction for anterior talofibular,calcaneofibular and cervical ligament. Our new reconstruction technique applying modified Chrisman and Snook technique is useful in stabilization for deficiencies of the ligament complexafter PVNS excisionat lateral ankle and subtalar joint.

Radiosynovectomy has been used as an effective treatment in patients with resistant synovitis after failure of long-term medication and intraarticular steroid injection. Although $^{90}Y$ silicate/citrate, $^{186}Re$ sulfide, and $^{169}Er$ citrate were approved in Europe for the appropriate radiopharmaceuticals for radiosynovectomy other radionuclides such as $^{32}P$-chromic phosphate, $^{165}Dy$-ferric hydroxide macroaggregate, $^{188}Rh$-microspheres, $^{153}Sm-particulate, and $^{166}Ho$-ferric hydroxide macroaggregate have been used in many countries. Reported success rates range from 40% to 90% for the different joints and underlying disease. In Korea, $^{188}Re$-tin-colloid and $^{166}Ho$-chitosan complex are now using as the major radionuclides in radiosynovectomy with good clinical results. A study on radiation synovectomy using $^{188}Re$-tin-colloid for patients with Korean rheumatoid arthritis shows the treatment resulted in the improvement of arthritis and well tolerated in our study, the radiosynovectomy with $^{166}Ho$-chitosan complex in 53 hemophilic patients markedly decreased intra-articular bleeding frequency and need for coagulation factor. This review inculdes general priciples in the application of radiosynovectomy and the clinical experience in Korea.

Klebsiella pneumoniae causes that liver abscess mostly, also spread to pneumonia, meningitis, urinary tract infections. Septic arthritis caused by K. pneumoniae is a quite rare and has not been reported in Korea. Therefore, the authors report a case of the septic arthritis in the knee joint caused by K. pneumoniae in a patient with type 2 diabetes mellitus and osteoarthritis of the knee that successfully treated by early detection and arthroscopic synovectomy.

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.
