Purpose: To report the treatment results of arthroscopic osteochondroplasty in osteochondral lesion of the talus. Materials and Methods: This study included 32 patients who had osteochondral lesion of the talus treated with arthroscopic osteochondroplasty and were able to be followed up over 3 years from 1999 to 2007. The mean follow up period was 48 (38-108) months, and 22 male patients and 10 female patients with a mean age of 34 (20-56) years were included. Locations of lesion were evaluated with simple X-ray and magnetic resonance imaging (MRI), and severities of lesions were classified by Berndt and Harty classification. All cases were treated by arthroscopic debridement or microfracture. The treatment results were assessed by American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale and subjective and functional score of Kailkkonen. The group treated by arthroscopic microfracture was compared with the group treated by arthroscopic debridement. Results: The mean AOFAS ankle-hindfoot scale was significantly improved 53 (${\pm}7$) points preoperatively to 84 (${\pm}8$) points postoperatively (P<0.001). The mean subjective and functional score was also improved 55 (${\pm}8$) points preoperatively to 88 (${\pm}8$) points postoperatively with statistical significant (P<0.001). There were no relations between the severity of lesions and the postoperative functional score of ankle (P>0.05). There were no significant differences in the clinical results between the group treated with arthroscopic microfracture and the group treated with arthroscopic debridement (P>0.05). Conclusion: Arthroscopic osteochondroplasty of osteochondral lesion of the talus shows excellent result in terms of patients' satisfaction. There were no significant differences in the clinical results between arthroscopic microfracture group and debridement group.

Purpose: The purpose of this study is to evaluate the result of arthroscopic excision of painful Os subtibiale and Os subfibulare. Materials and Methods: Sixteen patients who had accessory bone in the ankle joint were treated by arthroscopy. Os subtibiale was four cases and os subfibulare twelve. The average follow-up period was 9 months$(range:6{\sim}42months)$. All patients were evaluated clinically with physical examination and radiologically with simple X-ray and for further evaluation, eight with bone scan, three with computed tomography and twelve with magnetic resonance image. We estimated the result of resection with Ogilvie-Harris's criteria. Results: All parameters of subjective and functional evaluation were improved with statistical significance(p<0.05). At final evaluation, eight patients still complained of mild pain and among them, three patients for synovitis, three for tendinitis on MRI and two for incomplete resection. Conclusion: The arthroscopic resection is a very effective method for painful os subtibiale and subfibulare using small incisions and for treatment of associated lesion. The preoperative radiological evaluation is essential and magnetic resornance image is useful for detecting of associated lesion.

Purpose: The purpose of this article was to review the effectiveness of arthroscopic debridement and tuberoplasty, and to evaluate the clinical and radiologic results of our series for irreparable massive rotator cuff tears in the elderly. Materials and Methods: We reviewed articles that focused on the treatment options and decision making for irreparable massive rotator cuff tears. In particular, we summarized the reported results of arthroscopic debridement and tuberoplasty for irreparable massive rotator cuff tears in the elderly. Among consecutive patients who had arthroscopic tuberoplasty for irreparable massive rotator cuff tears in our series, thirty-two patients available for clinical and radiological evaluation at a mean follow-up of 29 months (range, 13-52 months) were enrolled and reviewed for the analysis. Results: At the last follow-up, the range of active forward flexion increased significantly with excellent pain relief and improvement in the ability to perform the activities of daily living. However, the group with less than 2 mm in preoperative acromiohumeral distance showed inferior postoperative results. Conclusion: Arthroscopic tuberoplasty may be an alternative option in irreparable massive rotator cuff tears for pain relief and improvement of range of motion. However, good results can not be expected if the acromiohumeral distance is less than 2 mm preoperatively and decreases postoperatively, or when the preoperative range of motion is less than $90^{\circ}$ on flexion and abduction.

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.

We treated a 37-year-old male with traumatic hematoma in the suprapatellar bursa that had developed in the form of persistent swelling on suprapatellar area of left knee after blunt trauma. Though there were no obvious abnormal findings on plain roentgenographs, an isolated suprapatellar cystic lesion with fluid-fluid level on T2-weighted sagittal image of MRI was noted. We found the suprapatellar plica with complete septum and no synovitis in the knee joint proper by arthroscopy. We incised the plica and found leakage of blood-stained fluid from the suprapatellar bursa. There were no findings of pigmented villonodular synovitis or other tumorous lesions. At 6 months after surgery, the patient felt symptom-free and there was no recurrence.

Purpose : We report a result of arthroscopic resection after inner-wall staining for treatment of prepatellar bursitis which was not treated conservatively. Materials and Methods : Between January 1996 and October 1998, We treated arthroscopically 11 patients with prepatellar bursitis. Arthroscopic resection was performed with shaver after inner-wall staining using Methylene Blue and then placed continuous suction drainage and compressive dressing. Results : All patients had no tender scars and were able to walk immediately after procedure. We found one case of late infection during follow-up. Conclusion : Arthroscopic bursectomy minimizes the complication of open bursectomy such as pain or large scar. Skin perforation would be prevented by inner-wall staining.

Purpose: We compared the clinical and radiological results of meniscectomy with HTO or without HTO for degenerative medial meniscus posterior horn with varus deformity. Materials and Methods: Forty-two patients who had medial meniscus degenerative root tear with varus deformity more than 3 degrees were included for this study. Among them, 30 patients were performed meniscectomy combined with open wedge HTO and 12 patients were performed only meniscectomy without HTO. The mean follow-up period was 52.5 months. The clinical results were evaluated based on symptom improvement, patients' subjective satisfaction for surgery and HSS score. We also compared the osteoarthritic progression between the group on preoperative and at the final follow up radiographs. Results: Symptom improvement was achieved in 83.3% (25 cases) with HTO group and 66.7% (8 cases) without HTO group at final follow up with a significant difference. Patients' satisfaction was achieved in 83.3% (25 cases) with HTO group and 58.3% (7 cases) without HTO group which has a significant difference. The HSS score was improved in both group (90.8: with HTO group, 89.0: without HTO group) at the final follow up without significant difference. WOMAC score was improved in both groups at the final follow up without significant difference. There were no significant differences in the osteoarthritic progression between two groups. Conclusion: The good clinical result for treatment of patient who have medial meniscus degenerative root tear with varus deformity, proximal high tibial osteotomy is considered absolutely necessary. However, the progression of degenerative arthritis, its effect on long term follow up will be needed.

Purpose : The purpose was to assess the result of arthroscopic management of the septic arthritis on the knee in compromised patients. Materials and Methods : Fourteen patients with septic knee were analyzed. The mean age was 55 years and the mean follow-up period was 14.6 months. Underlying diseases included 4 cases of diabetes, and history of direct acupuncture in 4 cases. Clinical stage of septic arthritis was judged by $G\ddot{a}chter's$ classification, which was determined by arthroscopic findings. After arthroscopic irrigation and debridement, we observed the results of laboratory data and improvement of clinical findings. Results : Causative organism was identified in 7 cases and no organism was detected in the remaining 7 cases. Stage I was 1, stage II 8, stage III 4, and stage IV 1, respectively. Eleven of 14 cases were improved by one stage operation. Two cases of stage III were recurred and additional arthroscopic management was done. In 1 case of stage IV, symptom was not improved and needed arthrotomy. The result was unsatisfactory in patients with stage III and IV. Serum erythrocyte sedimentation rate and C-reactive protein were normalized after 29.3 and 20.8 days following the operation, respectively. Clinical symptoms disappeared average 2 days following the operation. Conclusion : Arthroscopic management of acute septic arthritis of the knee would be an effective and satisfactory treatment modality in that its postoperative pain and complications are minimal, and it can be done with ease repeatedly.
