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.

Pigmented villonodular synovitis (PVNS) is a rare proliferative disease involving the synovial membranes. Complete excision with a total synovectomy is important for diffuse type PVNS because of its high recurrence rate. In the ankle, complete excision of diffuse type PVNS is difficult due to the anatomical structure of the ankle joint. This paper reports the author's experience of surgical treatment with combined open and arthroscopic synovectomy. In this manner, it is expected that the complications of the open procedure and the recurrence rate of arthroscopic procedure can be reduced.

Pigmented villonodular synovitis (PVNS) is a rare proliferative disease involving synovial membranes. Natural history and etiology of PVNS are not well known. PVNS presents as localized or diffuse tumor like nodular lesion of the synovial lining of the joint and the synovial spaces adjacent to the joints. Though histologically benign, it is a very aggressive lesion, capable of bone destruction and widespread infiltration of surrounding tissues. Standard therapy is surgical resection, but due to the infiltrative growth, the recurrence rate is significantly high. After several relapses surgical treatment of diffuse PVNS becomes difficult and may require amputation of the involved limb. Radiotherapy can provide an effective treatment option for patients with large lesions or lesions which are not suitable for surgery, after incomplete resection to prevent relapses or to avoid amputation. We report 2 cases of diffuse PVNS in the knee joint treated with arthroscopic gross total synovectomy and radiotherapy.

Purpose: To evaluate the efficiency of arthroscopic treatment for infected total knee arthroplasty (TKA), and to investigate the factors affecting the outcomes. Materials and Methods: We analyzed 17 cases which underwent arthroscopic treatment to treat infection after TKA. After confirming infection by hematologic examination and analysis of joint fluid, we performed arthroscopic debridement, synovectomy and irrigation with normal saline mixed with antibiotics. Through routine examination after operation, we checked failure of treatment or recurrence of infection. If there is no recurrence until 2 years after the operation, we considered it as a success of treatment. Results: Of the 17 cases taken arthroscopic treatment, 13 cases were treated successfully with primary arthroscopic treatment only, but 4 cases had to undergo re-operation because of persistence or recurrence of infection. Analyzing the factors affecting the results, we found that symptom duration of the re-operation group is longer than the treated group after arthroscopy (p<0.05). Conclusion: Arthroscopic treatment can be effective when we performed appropriate selection of patients, careful and extensive arthroscopic irrigation and debridement, and suitable use of antibiotics. However, we have to do early arthroscopic surgery as soon as possible when infection after TKA is suspected.

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 mini-open 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.

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.

Purpose: This study analyzed the treatment effects of drain insertion in the posteromedial portal after an arthroscopic synovectomy and posterior septum resection for pyogenic arthritis. Materials and Methods: From June 2005 to December 2016, 56 cases (55 patients, 1 case of bilateral knee) were diagnosed with pyogenic arthritis and arthroscopic treatment was performed. Fourteen patients (25.0%) were identified with causative organisms. The average follow-up period was 12.3 months, and the mean age was 67.8 years old. Twenty-four cases were males and 31 cases were females. Kellgrene-Lawrence grade (K-L grade) I was 6 patients, II was 20 patients, III was 11 patients, and IV was 18 patients. Surgery was performed through six portal. The posterior septum was removed and a drainage tube was inserted from the posterior medial side to the posterior side of the joint. The Lysholm score was used after surgery for a functional evaluation. The K-L grade at the time of admission and at the last follow-up were compared for a radiological evaluation. Results: The mean normalization period of the C-reactive protein was 59.8 days (6-164 days). Intravenous antibiotics were used for an average of 37.1 days. The results of the functional evaluation revealed a mean Lysholm score of 64.5 (30-98) in a total of 56 cases. Two reoperations was performed, but the treatment was completed with same method in all patients. The K-L grade was similar at the time of surgery and at the last follow-up (p>0.05). Conclusion: The method of drain insertion in the posteromedial portal after arthroscopic synovectomy and posterior septum resection for pyogenic arthritis is an effective technique that can obtain satisfactory results by inducing proper exudate discharge.

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.
