Pigmented villonodular synovitis (PVNS) is a rare benign proliferative disorder that results in villous hyperplasia and nodule formation in the synovium, tendon sheath and bursa. That most commonly affects the knee and the hip joint in adult. PVNS of the hand, the wrist, the shoulder and the elbow is rare and that of the elbow in children is particularly rarer. An eight-year-old boy had his left elbow pain and a lesion like benign bone tumor in the left fossa olecrani on plain x-ray. During the operation, abnormal synovial hyperplasia in his left elbow joint led us to diagnose PVNS. Therefore, open curettage of the lesion and radical synovectomy was performed. The specimen of the synovectomized tissue revealed PVNS. The left elbow pain subsided after the operation and the child restored a full range of motion of his left elbow. We reported this rare case of PVNS in a child's elbow joint mimicking the bone tumor together with a review of the literature.

Purpose: Diffuse pigmented villonodular synovitis (PVNS) is an uncommon aggressive synovial proliferative disorder of unknown etiology affecting the joint linings. Though a histologically benign inflammatory process, because of its aggressive growth with bone destruction or recurrence, it is frequently suggested to occur as a low malignant neoplasm. Optimal treatment is surgery, but the local recurrence rate after radical synovectomy for diffuse PVNS is relatively high due to the infiltrative growth pattern. External beam radiotherapy with moderate doses or intra-articular instillation of radioactive isotopes may improve the likelihood of local control and long-term function in patients with incompletely resected or recurrent diffuse PVNS. I report one case of diffuse PVNS of the right knee joint treated with arthroscopic synovectomy and external beam radiotherapy is presented.

Purpose : To confirm the efficacy of arthroscopic synovectomy for the pigmented villonodular synovitis in the knee. Materials and Methods : We analysed 8 patient(9 cases) that were diagnosed and performed arthroscopic synovectomy as pigmented villonodular synovitis from July 1992 to May 2000. The diagnosis was confirmed by pathologist. The average follow-up period was 29 months(range, $15\~48$ months). The average age at initial visit was 40.4 years(rage, $15\~67$ years). Male were 6 cases and female 2 cases. The average duration from onset of the symptom to the operation was 23 months($2\~86$ months). Previous history of the trauma was noted in 2 case. There was 1 case involved both knee joints. Results : According to the athroscopic findings, there were 4 localized forms and 5 diffuse forms. At preoperational examinations, the average of flexion contracture was $4.4^{\circ}(0\~5^{\circ})$ and that of the further flexion was $117.8^{\circ}(90\~135^{\circ})$. At last follow-up examinations, the knee range of motion was normalized, the average of flexion range was $133.9^{\circ}(120\~140^{\circ})$. All patients had improvement in pain, swelling and range of motion and there was no evidence of recurrence. Conclusion : In the pigmented villonodular synovitis, arthroscopic synovectomy can be considered one of the good modality to expect good results.

Purpose : We evaluated the results of the arthroscopic treatment of nine cases of synovial chondromatosis in the knee joints. Materials and Methods : From June 1989 to September 1999, eight patients nine cases with synovial chondromatosis involving knee joints underwent arthroscopic total synovectomy and removal of loose bodies. There were 6 females and 2 males. The average age at surgery was 44.1 years(range, 20-57 years). The average follow-up period was 5.9 years (range, 2.5-7.3 years). All cases had pain and swelling and two cases had locking preoperatively. Flexion contracture was found in three cases. Results : Pathologic finding revealed Milgram I in one case, Milgram II in six cases and Milgram III in two cases. There were six cases of generalized synovial hypertrophy and one case of localized type. All patients had symptomatic relief by arthroscopic total synovectomy and loose body removal. Second arthoroscopic surgery was performed in one patient due to recurred lesions 11 months after the primary surgery. Conclusion : Clinical results of the synovial chondromatosis with arthroscopic total synovectomy and loose body removal were satisfactory. Arthroscopic total synovectomy was also effective for the recurred case.

Purpose: Here we report a case of pigmented villonodular synovitis of the shoulder associated with a rotator cuff tear. Materials and Methods: A 52 year-old female who had suffered from pigmented villonodular synovitis of the shoulder associated with a rotator cuff tear was treated with arthroscopic synovectomy and subacromial decompression. Results: Pain was reduced and the patient achieved a good functional outcome after surgery. Conclusion: The current authors report a case of pigmented villonodular synovitis of the shoulder associated with rotator cuff tear and a review of literature.

The knee joint is most commonly affected. Until now, there were several reports of this condition, but this report seems to be the first one reporting localized Pigmented Villonodular Synovitis (PVNS) after anterior cruciate ligament(ACL) reconstruction. The authors experienced localized PVNS after ACL reconstruction with bone-patellar tendon-bone at follow-up 4 years and confirmed the diagnosis by pathologic examination.

Synovial hemangioma of the knee joint has been reported as a rare cause of pain, limitation of motion and hemarthrosis, often seen as an internal derangement of the knee. A 39-year-old woman presented with spontaneous hemarthrosis of the left knee joint and physical exam revealed a small painful mass adjacent to the medial side of the patella. Magnetic resonance imaging revealed an intra-articular tumor. Arthroscopic excision was performed and the histology was characteristic of hemangioma. Through this case, we discuss the diagnosis and treatment options for the synovial hemangioma of the knee.

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.

세균성 감염 관절염은 활액막염(synovitis)으로서 활액막에 염증이 생겨 발병하게 된다. 일반적으로 관절염과 건초염(tenosynovitis)은 동시에 발생하는 경향이 있으며, 관절염이 발병한 브로일러 종계는 결국 도태시킬 수밖에 없다.
