Purpose: To study the clinical and radiologic results with arthroscopic Bankart repair using knotless metal suture anchor. Materials and Methods: From February 2001 to January 2005, 68 patients, who underwent arthroscopic Bankart repair using knotless suture anchor and were followed up more than 12 months, were evaluated. A mean follow-up period was 34 months. All shoulders were evaluated by Rowe scoring system, range of motion of the shoulder, pain degree of VAS, and This was compared by radiologic findings after surgery. Results: The Rowe scoring system was 43.30 preoperatively, which improved to 95.55 postoperatively. At last follow-up, there was no significance difference between operated shoulder and non-operated shoulder in range of motion. The degree of VAS was measured from 3.3 preoperatively to 0.5 postoperatively. The radiolucent line was shown around suture anchor in 15 shoulders. 2 shoulders of 15 shoulders were reoperated due to redislocation and anchor arthropathy. In Odds ratio, this group (15 patients) had more 2.6 times the subjective instability than other group (53 patients). Conclusion: Arthroscopic Bankart repair using knotless anchor suture is very effective operative technique. But we have to be careful because the radiolucent line around anchor showed up during a follow -up period may indicate poor prognosis.

Purpose: To investigate the MRI and arthroscopic findings of osteochondral lesion of the talus which looked normal on plane radiography. Materials and methods: We investigated the MRI and arthroscopic findings of seven osteochondral lesions in which there were no abnormal finding on plane radiography and no cystic changes on MRI. Average age was 31 years(range, 19-43 years). Arthroscopic findings were classified according to the Ferkel's criteria. Results: History of injury was reported in all cases and the average duration from injury to presentation was 4 years and 4 months. Low signal change in T1WI was found in 6 of 7 lesions, no signal change in 1 case. Low signal change in T2WI was found in 4, no signal change in 3. 6 STIR images were obtained. High signal change was found in 3, no signal change in 2 and intermediate signal change was in 1. Arthroscopic grading was A in 1, C in 1, D in 2 , E in 1 and F in 2. We could not find any correlation between the findings on MRI and arthroscopic examination. Conclusion: We suggest arthroscopic examination is needed for accurate diagnosis of the osteochondral lesions of the talus which looked normal on plane radiography, because they have various MRl findings and high likelihood of existence of unstable cartilage lesions.

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.

Pretibial ganglion cyst after arthroscopic anterior cruciate ligament reconstruction is a very rare complication, and a few are reported in and outside the country. Some authors report that it may break out with a variety of causes at any time. We experienced a case of pretibial ganglion cyst after arthroscopic anterior cruciate ligament reconstruction using Achilles tendon allograft and bioabsorbable interference screw in 34-year-old male. So we report this case including the cause and the treatment with a review of the literature.

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.

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.

We describe in this report the accurate reduction of a transverse displaced glenoid fracture through arthroscopic control . We used the lateral and superior (Neviaser portal) portal of the arthroscopic surgery in the shoulder joint for the U 4.0-mm titanium cannulated cancellous screw fixation. The advantages of this treatment are excellent intra-articular visualiBation, decreased soft tissue dissection ,less blood loss, shortened postoperative recovery and early ROM exercise. There(ore, we report the method of operation and the cases .

Purpose: A meta-analysis was performed to assess the outcomes following surgical intervention for medial knee plica. Materials and Methods: A literature search of Medline, EMBASE, CINAHL and Cochrane CENTRAL was performed using relevant key words. The primary outcome was patient-reported postoperative scores of "good" and "excellent". Meta-analyses were performed using a random effects model. Results: The literature search identified 731 articles. After removing duplicates and those not meeting the inclusion criteria, 12 articles reporting on a total of 643 knees were included for analysis, and of these, 7 articles including 235 knees were used for meta-analysis. The overall rate of good and excellent outcomes following surgery was estimated at 84.2% (95% confidence interval [CI], 72.8-91.4). In those cases that had non-surgical therapy prior to surgery, the rate of good and excellent outcomes of surgery was estimated at 76.1% (95% CI, 60.1-87). Conclusions: Arthroscopic surgical management of symptomatic medial knee plica results in favourable outcomes. Our results suggest that arthroscopic surgical excision should be considered as a treatment modality in patients with pathological medial plica disease of the knee either as a first-line treatment or when symptoms have not responded to non-surgical interventions. Level of Evidence: IV.

Purpose: This study reports the clinical results of the arthroscopic repair of type II SLAP lesion with bio-knotless anchor. Materials and Methods: 25 cases of 25 patients (20 male, 5 female) were included in this study. The average age was 44.5 years old. Preoperative ASES score was average 44. Arthroscopic SLAP repair with 1 or 2 bio-knotless anchors were performed in all cases. The average follow up period was 15 months. Results: The ASES score improved to average 92.7 at last follow up period and 23 cases had full range of motion of the shoulder. 2 case had mild limited range of motion of the shoulder without any problem in normal activity. Conclusion: Arthroscopic repair with bio-knotless anchor in type II SLAP lesion is one of the good methods because of the good clinical results.
