Purpose: To evaluate effectiveness of arthroscopic capsular release combined with manipulation in frozen shoulder. Material and Method: 15 patient who had failed to respond to physical therapy were evaluated, which were treated with arthroscopic capsular release combined with manipulation, from July 1998 to March 2000. Result: At a mean of fifteen months(range, six to twenty four) after the combined procedure, the improvement in the score of Constant and Murley averaged 45 points. The mean improvement in motion was 76 degrees for abduction; 40 degrees and 65 degrees for external rotation in adduction and abduction. Conclusion : Arthroscopic capsular release with manipulation is useful method to treatment the frozen shoulder which was not respond to conservative treatment.

Background: Recent studies have reported high rates of recurrence of shoulder instability in patients with glenoid bone defects greater than 20% after capsulolabral reconstruction. The purpose of the present study was to evaluate the failure rate of arthroscopic capsulolabral reconstruction for the treatment of anterior instability in the presence of glenoid bone deficits >20%. Methods: Retrospective analyses were conducted among cases with anterior shoulder instability and glenoid bone defects of >20% that were treated by arthroscopic capsulolabral reconstruction with a minimum 2-year follow-up (30 cases). We included the following variables: age, bone defect size, instability severity index score (ISIS), on-/off-track assessment, incidence recurrent instability, and return to sports. Results: The mean glenoid bone defect size was 25.8%±4.2% (range, 20.4%-37.2%), and 18 cases (60%) had defects of >25%. Bony Bankart lesions were identified in 11 cases (36.7%). Eleven cases (36.7%) had ISIS scores >6 points and 21 cases (70%) had off-track lesions. No cases of recurrent instability were identified over a mean follow-up of 39.9 months (range, 24-86 months), but a sense of subluxation was reported by three patients. Return to sports at the preinjury level was possible in 24 cases (80%), and the average satisfaction rating was 92%. Conclusions: Arthroscopic soft tissue reconstruction was successful for treating anterior shoulder instability among patients with glenoid bone defects >20%, even enabling return to sports. Future studies should focus on determining the range of bone defect sizes that can be successfully managed by soft tissue repair.

Purpose: We introduce arthroscopic assisted core decompression for humeral head osteonecrosis. Operative technique: After diagnostic shoulder arthroscopy is performed using posterior and anterior portal, we make a 2 cm lateral skin incision approximately 3 cm distal to 1/3 of lateral margin of the acromion and place short gray cannula to prevent adjacent soft tissue injury when insert guide pin. Under C-arm fluoroscopic and arthroscopic guidance, 3 to 4 guide pins are inserted toward the necrotic area. Then we perform drilling using 7.0 mm reamer. Conclusion: We believe this technique is a less invasive approach and avoids the complications comparing to deltopectoral approach. Arthroscopic assisted core decompression is an effective procedure in management of early stage of the humeral head osteonecoris.

This study was undertaken to document the clinical results and technical aspects of arthroscopic repair including popliteus tendon as a post for the treatment of complex lateral meniscus in young people indicated as total meniscectomy. From June 2004 to May 2006, we prospectively studied arthroscopic repairs on 32 young people knees with symptomatic complex lateral meniscus that was treated by all inside repair technique using Popliteus tendon as a post. Clinical results were evaluated using Lysholm knee scores preoperatively and at final follow-up. 2nd look arthroscopy or MRI was taken at final follow-up. 80% of patients carried out MRI or 2nd look arthroscopy under permission. Most patients who follow up were able to return to their previous life activities with little or no limitation, and no reoperation was required after an average follow-up of 42.8 months. Mean Lysholm knee scores improved from 65.4 (range, 55 to 75) preoperatively to 93.9 (range, 79 to 100) at the final follow-up (P<.001). 80% meniscus healing was found on arthroscopic or MRI follow up. Conclusively, arthroscopic repair using Popliteus tendon as a post is effective for treating young people with complex lateral meniscus tear as a salvage procedure.

Purpose: The purpose of this study is to evaluate the clinical results for the treatment of osteoarthritis of the knee by arthroscopic procedure according to presence or absence of mechanical symptoms. Materials and Methods: We studied sixty patients (60 knees) who underwent arthroscopic procedure for the treatment of osteoarthritis of the knee from October,2000 to January,2002. The average follow up period was 15 months(12-30 months). We evaluated the mechanical symptoms by simple radiographs, history taking and physical examination. We analysed the clinical results by Baumgaertner's scale. Results: The Baumgaetner's score improved from 3.1 preoperatively to 8.1 postoperatively in the group with mechanical symptoms, whereas the scores in the group without mechanical symptom improved from 3.5 preoperatively to 5.4 postoperatively. The patients with mechanical symptoms were satisfied more than the patients without mechanical symptoms. Conclusion: The arthroscopic surgery could be one of good alternative treatment methods for the osteoarthritis of the knee with mechanical symptoms . But, more than these patients will be needed for further evaluation.

Heterotopic ossification is formation of bone in atypical extra-skeletal tissues and usually occurs spontaneously or following neurologic injury with unknown cause. We report a 46-year-old female with right shoulder pain and restricted range of motion (ROM) for 3 months without history of trauma. Magnetic resonance imaging (MRI) showed a lesion within the rotator cuff supraglenoid. Excisional biopsy from a previous institution revealed a heterotopic ossificans (HO). Following repeat MRI and bone scan, histopathology from arthroscopic resection confirmed an HO. The patient demonstrated improved pain and ROM at follow-up. Idiopathic HO rarely occurs in the shoulder joint, and resection of HO should be delayed until maturation of the lesion to avoid recurrence. The current case showed that arthroscopic HO resection provides an excellent surgical view to ensure complete lesion removal and minimize soft tissue damage at the supraglenoid area. Furthermore, the minimally invasive procedure of arthroscopy may reduce rehabilitation time and facilitate early return to work.

Avulsion fractures of the intercondylar eminence of the tibia are uncommon. This kind of fracture is most commonly found in adolescents, with an increasing incidence for those involved in competitive athletics. Recently, an arthroscopic procedure is preferred to reduce the operation-related morbidity. Screws, K-wires, Suture anchor have been described as fixation devices. Cannulated screw fixation is a simple method, but this instrument has the risk of causing damage to the growth plate. The authors report good results using cannulated screw in arthroscopic treatment for pediatric anterior cruciate ligament avulsion fracture.

Trans-posterior septal posterior arthroscopic portals are useful in performing arthroscopic diagnosis and treatment of the lesions located in posterior aspect of knee joints. Except inferior surface of posterior horn of lateral meniscus, we easily observed entire lateral compartment, especially inferior surface of anterior horn and lateral tibial condyle by figure of 4 position through posteromedial trans-posterior septal arthroscopic portal. And it was possible to obtain visual field from posterior aspect and we could use anteromedial and anterolateral portals for instrumentation without clouding. So, this procedure may be useful in performing surgery of lateral compartment especially, anterior aspect in the knee joints.

A medial opening wedge supramalleolar osteotomy (SMO) introduced by Takakura et al. is a useful realignment procedure for patients with ankle joint arthritis and varus malalignment by shifting the weight-bearing axis laterally and redistributing the loads on the ankle joint. When pain persists after arthroscopic microfracture in patients with medial osteochondral lesion of the talus (OLT), redo arthroscopy, osteochondral autograft transplantation, autologous chondrocyte implantation, or matrix-induced chondrogenesis might be indicated. On the other hand, there is insufficient scientific evidence for realignment surgery through SMO, while the effect of realignment surgery has been studied consecutively for osteochondral lesions of the knee. Therefore, this paper reports a patient with medial OLT who underwent redo arthroscopy combined with SMO for persistent pain after primary arthroscopic microfracture.
