Purpose : The clinical consequences of arthroscopic Bankart repair using suture anchor with non-absorbable suture as well as various factors, expected to have an effect on the prognosis of disease, have been evaluated and compared through preoperative and postoperative modified Rowe score. Materials and Methods : Twenty-eight cases were evaluated for the subject of this study, which enabled us to follow up at least for more than 18 months from lune, 1997 to May, 2001. Modified Rowe score was used for the evaluation of preoperative and follow-up shoulder function and stability. After setting up 9 factors expected to affect a prognosis, a statistical verification was conducted. Results : The postoperative Rowe score was 87.3, while preoperative Rowe score was 28.4 and the Rowe score was improved significantly(p=0.000). There were 1 case of redislocation and 2 cases of limitation of motion in the shoulder. In prognostic factor analysis through Rowe scoring system. Rowe score of their age at a trauma under 20 years was greater than that of above 20 years and it was significant(p=0.023). Conclusion : It was thought that arthroscopic Bankart repair using suture anchor was one or useful treatment method for recurrent shoulder dislocation patients. It was considered that their age at initial trauma was the factor to affect a prognosis.

Purpose: The purpose of this study is to analyze the results of acute acromioclavicular joint dislocation treatment with coracoclavicular ligament augmentation using Tight-Rope$^{(R)}$ (Arthrex). Materials and Methods: From October 2009 to March 2011, 30 patients with acute acromioclavicular joint dislocation underwent coracoclavicular ligament augmentation using Tight-Rope$^{(R)}$ and were followed up for at least 12 months after surgery. The radiologic results were qualified according to serial plain radiographs, and the clinical results according to University of California - Los Angeles (UCLA) Shoulder Scale, Constant score, and VAS pain score. Results: Using the UCLA scoring system, excellent results were observed in 22 cases (73%), good results in five cases (17%), fair results in two cases (7%), and a poor result in one case (3%). The average Constant score was $92.5{\pm}7.5$. According to radiologic results, anatomical reduction was achieved in 26 cases, and two cases showed a moderate loss of reduction, and two cases showed complete re-dislocation. Clinical results for patients with re-dislocation were unsatisfactory and reoperation was required. Conclusion: Coracoclavicular ligament augmentation using Tight-Rope$^{(R)}$ is a good option providing reliable functional results in patients with acute acromioclavicular joint dislocation.

Fibrous dysplasia is a benign pathologic condition in which the normal cancellous bone is replaced by the fibro-osseous tissue. It is found mostly in the femur, tibia, skull, rib, and humerus. Clinically it may develops pain, progressive deformity, and pathologic fracture. Curettage with bone graft has been the most popular treatment method thesedays. A 17-year-old female who had fibrous dysplasia of the humerus combined with multiple cystic lesion was treated by intralesional steroid injection into the lesion total 2 times. The follow-up plain X-ray which was taken 11 months after steroid injection reveals decrease in size and increase in bone density and cortex thickness. The follow-up MRI reveals significant decrease in size and signal intensity. The signal intensity was decreased to that of normal bone marrow in T2 weighted image. She complains no pain and lives symptom free in last follow-up at 2 years and 8 months after steroid injection.

Purpose: To evaluate the results of the compression plate fixation and autogenous bone graft in the management of humerus shaft nonunion. Materials and Methods: Eighteen cases were treated for humerus shaft nonunion using compression plate fixation and an autogenous iliac bone graft. The mean follow-up period was 28 months. Bony union was confirmed from the serial radiographs and the clinical outcomes were assessed according to ASES scoring system. Results: In 12 cases of initial plate fixation, the causes of nonunion were 6 cases of inadequate plate length, 2 with a broken plate, 2 with screw loosening, 1 infection and 1 noncompliance of a psychiatric patient. In 3 cases of initial intramedullary fixation, the cause of nonunion was a distraction of the fracture site. In 3 cases of external fixation, the cause of nonunion was inadequate fixation. All cases showed bony union after an average of 24 weeks. The clinical outcomes were 11 excellent, 6 good and 1 fair. Conclusion: In the treatment for nonunion, compression plate fixation with autogeneous bone graft after complete removal of the fibrous and necrotic tissue is believed to give satisfactory results.

Purpose: This study evaluated the preoperative and postoperative radiologic findings of patients with complete repairs after massive rotator cuff tears along with the incidence of re-tear and the clinical outcomes. Materials and methods: This study evaluated 33 cases who had open complete repairs for massive rotator cuff tears and these patients were followed up for more than 24 months. The clinical evaluation was performed according to the shoulder joint function test of the American Shoulder and Elbow Surgeons (ASES), and the degree of arthritis related to the massive rotator cuff tears was evaluated using the Hamada classification. Results: The ASES scores improved from 37.6 preoperatively to 85.6 postoperatively. The mean preoperative acromio-humeral interval (AHI) score was 6.5 mm, which increased to 9.3 mm immediately after surgery, and there was a decreased to 6.5 mm noted at the last follow up. The lower radiology stages of arthritis according to the classification showed better preoperative and postoperative results. Conclusion: An open complete repair as the surgical treatment for a massive rotator cuff tear showed satisfactory results for pain relief and an improvement in the shoulder joint function though re-tear after surgery.

Purpose: We evaluated the level of pain and clinical presentation of calcific tendinitis after treatment with conservative and early arthroscopic operation. Materials and Methods: We reviewed 30 patients with calcific tendinitis with the minimum of 6 months of follow up period, treated from February 2002 to May 2008. We implemented Constant-Murley score to evaluate the pain of calcification and improvement of range of motion at the 2nd week, 12th week and 24th week with the patients who had treatment with steroid injection in 15 cases and operation in the other 15 cases. Results: Evaluating the level of pain using Constant-Murley score, we found that conservative treatment group had the scale of 3.2 before treatment and 13.6, 14.5 and 14.7 at 2nd, 12th, and 24th week, respectively since started treatment. The operation group, on the other hand, had the scale of 3.3 preoperatively and 10.2, 13.0, and 14.3 at 2nd, 12th and 24th week postoperatively. The range of motion in the conservative treatment group showed 14.3 on average before the treatment and 21.7, 31.3 and 35.7 at 2nd, 12th and 24th week after treatment. The operation group had 14.4 on average preoperatively, and 33.1, 35.8 and 36.4 at 2nd, 12th and 24th week postoperatively. The operation group had statistically significant improvement compared to the conservative group at the 2nd and 24th week, but showed no difference between the two groups at the final follow up. Conclusion: Early arthroscopic treatment of calcific tendinitis seems to be an excellent option that can increase the level of satisfaction of the patients and an efficient way of putting the patients back to their normal life promptly.

Iliacus muscle tears are a rare injury seen after the high-energy trauma or as a result of low-energy injuries in patients with a bleeding diathesis as coagulopathy, receiving anticoagulation therapy and hemophiliac. Femoral nerve palsy due to compression from a hematoma by iliacus muscle rupture are rarely reported. Routine evaluation includes MRI to confirm and define the pathologic abnormality supplemented by EMG and nerve conduction studies to evaluate patterns and extent of femoral nerve injury. Hematologic evaluation for bleeding diathesis may preceded, if suspicion of coagulopathy is present. We report the case of a healthy 32-year-old male with iliacus rupture and concomitant femoral nerve palsy sustained by kicking motion during soccer game. After 6 months of observation with non-operative treatment regimen, satisfactory results were obtained, so we report it with a review of the literatures.

As survival rate of patients in osteosarcoma improves, both patients and surgeons are increasingly interested in long-term functional outcome. For resection and reconstruction of tumors on either side of knee joint, if feasible, conservation of normal joint apparatus seems preferable method over use of tumor prosthesis. However, we should not trade off the sound surgical margin with expected functional gain. We report one case of osteosarcoma who was treated by wide, intercalary resection and reconstruction with autogenous pasteurized bone but, showed local recurrence at 44 months postoperatively.

Purpose : This study was to evaluate the effectiveness of arthroscopic management for septic elbows. Materials and Methods : The subjects were 7 patients ranged in age from 6 to 32 years. All patients were diagnosed as having septic arthritis of the elbow after arthrocentesis. Emergency arthroscopic lavage, debridement, and selective synovectomy for infective and necrotic tissue were performed. All patients had a follow-up period of more than 12 months by checking leukocyte count, ESR, CRP and range of motion. Results : For children, we found a return to normal of laboratory tests for infection after an average of 8.4 days while for adults, it required 12.3 days. After 12 months all patients showed normal elbow function as well as normal blood tests. Conclusion : We found arthroscopic management for septic arthritis of the elbows made it possible to visualize the pathologic findings directly and protect further articular damage. In conclusion, arthroscopic management is one of the efficient methods for controlling the joint infection.
