Purpose: Limitation of motion of the elbow joint due to stiffness affect on life quality of the patients. So contracture of the elbow should be treated as soon as possible. Among the many treatment modalities, we described the result of arthroscopic treatment. Materials and Methods: From Mar. 2000 to Mar. 2003, 40 patients, who received the arthroscopic treatment by author for contracted elbow, were the subjects. We estimated the range of motion (ROM) of elbow joint before and after surgery by goniometer. The clinical result was evaluated by Severance elbow scoring system. The final ROM was evaluated at the point of no further increasement of joint motion. Male ware 30 cases, female ware 7 cases, average 42.6 years old and mean follow up period were 31 months. During arthroscopic treatment we had done release of the joint capsule or resection, synovectomy, removal of loose bodies. We used traditional portals. Results: The avarage preoperative ROM of elbow joint was 72.5 degree(range, 5 - 132 degree) and the increasement of ROM was totally 49.3 degree in flexion 26.5 degree and extension 22.8 degree. There was no other complication. Conclusion: Arthroscopic treatment for contracted elbow permit early joint ROM and it decrease the secondary injury to the elbow joint. Also there are few complications. It is thought to be a good treatment modality in contracted elbow joint.

Appropriate clinical examination and imaging may lead to early diagnosis and treatment of the shoulder impingement syndrome, thus preventing progressing to a complete tear of rotator cuff. The impingement syndrome was caused by repeated entrapment and compression of supraspinatus tendon between the proximal end of humerus inferiorly, particullary its greater tuberosity. and one or m <)re component of coracoacromial arch superiorly. The purpose of this study is to critically, evaluate the result of twenty-five consecutive subacromial decompression with impingement syndrome and to assess the diagnostic accuracy of MR imaging by using oblique coronal and oblique sagittal plan. These patients were treated by arthroscopic subacromial decompression after their pains failed to improve with conservative therapy over three month. The average follow up was 25 month(range, 12 to 50). The mean age was 43 year old. The results were rated based on subjective response and the UCLA shoulder rating scale of the result. Ten patients(40%) were rated as excellent, 11patients(44%) were good. while four patients(16%) were fair. Radiologic evaluation suggested that the oblique sagittal plan of MRI can be helpful in evaluation of bony and soft-tissue structure of the coracoacromial arch and determining depth of bony resection. There were no infection or neurovascular injury. In reviewing our result, it appears that the arthroscopic subacromial decompression can be successful sugery for shoulder impingement syndrome and diagnostic accuracy of supplimentary oblique sagittal view of MRI was relatively higher than oblique coronal view alone for apprqpriate surgical plan.

Purpose : To analyze the clinical result of the arthroscopic decompression of meniscal cyst and meniscus resection or repair of meniscus tear. Materials and Methods : From April 1994 and October 2001, 19 patients with diagnosis of meniscal cyst associated with tears of the meniscus were treated by arthroscopic meniscal resection or repair with decompression of the cyst. The mean age was 39.8 years(range, 22-58years). The follow-up period ranged from 3 months to 36 months with an average of 18 months. Seven of 19 patients had tenderness over the joint line with palpable mass. Treatment consists of arthroscopic resection or repair of meniscal tear with decompression of the cyst through transmeniscal approach. Open excision of cyst was performed in one case. Clinical evaluation was performed using Lysholm knee score and Tegner activity. All cases were executed proper treatment using arthroscopy. Results : Twelve cysts involved the lateral meniscus$(64\%)$ and seven cysts were on medial cyst$(36\%)$. Most of lateral meniscal cysts were located in anterior one-third and medial meniscal cyst were on posterior one-third. Meniscal tear were observed in seventeen cases$(89.5\%)$ and most tears were horizontal$(79\%)$. Preoperative symptom disappeared and no cyst recurrences were observed at last follow-up(mean follow-up: 18 months). Conclusion : Meniscal cysts involved lateral side in $64\%$ and most of them were associated with meniscus tear$(89.5\%)$ which consists of mainly horizontal component$(79\%)$.

Freiberg disease is a relatively rare osteochondrosis of metatarsal head, which usually involves the 2nd metatarsal of adolescent females. Various open surgical treatments have been recommended; arthrotomy and removal of loose body, dorsiflexion osteotomy and resection of the metatarsal head. Arthroscopic treatment for Freiberg disease has a merit of shortening the recovery period and reducing the postoperative stiffness. We report a case of early stage Freiberg disease treated with metatarsophalangeal arthroscopic excision of loose body and debridement of the 2nd metatarsophalangeal joint.

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.

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.

A new method for arthroscopic resection of the inferior leaf for the horizontal tear in the anterior horn of the meniscus extending deep toward the capsule was developed. Resection of this tear is difficult-perhaps more so than any other meniscal tear. At arthroscopy, a small incision on the meniscotibial ligament of the anterior horn was made after the deep horizontal tear was carefully debrided. A retrograde punch was introduced through the incision and underneath the inferior leaf of the anterior meniscus. The inferior leaf of the anterior horn was resected by the punch without difficulty. This simple technique minimizes the risk of superior leaf injury and can be used for a horizontal tear in the anterior horn as well as the mid horn with sweeping motion of the retrograde punch.

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.

Hereditary multiple exostosis (HME) is an autosomal dominant disorder manifested by the presence of multiple osteochondromas. Although the lesions are benign in nature, exostoses are often associated with characteristic progressive skeletal deformity and displaying clinical symptoms such as mechanical irritation or impingement. We present the successful arthroscopic resection in a 24-year-old HME male with impingement syndrome and long head tendon tear of the biceps caused by osteochondroma arising from the distal clavicle.
