The arthroscopic treatment may prove to be the desirable method, but this arthroscopic technique cannot be appliable to all surgeons and all patients, It should be determined on the base of type of lesion, effectiveness of arthroscopic procedure, and the surgeon's skill. The Key to an excellent result in arthroscopic treatment of rotator cuff lesion is doing a proper diagnosis, well-established arthroscopic technique and following through a well-designed rehabilitation program.

Purpose: The purpose was to identify the effectiveness of beach-chair position in the arthroscopic Bankart repair over conventional lateral decubitus position with distal traction. Materials & Methods: 36 arthroscopic Bankart repair through July 2000 to July 2001 was done under beach chair position. All cases were shoulder instability. Male patients were 6 and female were 4 with average age of 25 years. Arthroscopic suture anchor was used in 24 cases and average number was 3. Results: Interscalene block was tried in 29 patients and 1 case was changed to general anesthesia. Arthroscopic examination to identify Bankart lesion and associated pathology was done without difficulty Bankart lesions were easily reduced to anatomic position and placed suture anchor and hooking approprately. After the arthroscopic examination,3 cases were converted to open procedure without any positional change. Conclusion: Under interscalene block, the preparation was more simple and the patient could watch arthroscopic procedure with confidence. There was no hindrance in arthroscopic examination and arthroscopic repair could be dont: in more anatomic position. It can be easily changed to open repair if it needed

Although arthroscopic surgery has been used conventionally, it has not been widely adopted yet due to the risks of complications, including nerve damage, technical difficulties, and limited indications. As shown in other joints, however, the use of an arthroscope will gradually increased in the elbow joint ('Arthroscopy always wins'). Herein, arthroscopic treatments and arthroscopic ulnar nerve decompression will be discussed in cases of elbow osteoarthritis.

Object: To evaluate the efficiencies of the arthroscopic rotator cuff surgery which is Performed without the traction system in the lateral decubitus position. Methods: Twenty-nine cases of the arthroscopic rotator cuff surgery performed without the traction system in the lateral decubitus position were studied from February, 2002 to January, 2005. We performed a repair using the arthroscopic debridement and the arthroscopic rotator cuff repair, or using the mini-open incision technique after the confirmation of rotator cuff tear, then, the arthroscopic subacromial decompression was performed after the confirmation of subacromial lesions Results: We could easily find the subscapularis tear which was often overlooked in the arthroscopic rotator cuff surgery performed with the traction surgery by the relaxation of the subscapularis, as the arm position was internally rotate about 45 to 70 degrees from abducted position. We found that the operation time was reduced 14 minutes shorter than the operation time of the controlled group which had the surgery with the traction system on the average. We also found that there were no neurovascular complications from all cases. Conclusions: The arthroscopic rotator cuff surgery without traction system in the lateral decubitus position provided the better visual field, easy manipulation of the joint and reducing operation time.

Background: Management of massive rotator cuff tears can be challenging because of the less satisfactory results and a higher retear rate regardless of the use of open or arthroscopic repair technique. Methods: We retrospectively analyzed 102 cases of massive rotator cuff tear treated with either open or arthroscopic repair. Open repair was performed in 38 patients; and arthroscopic repair, in 64 patients. The mean age at the time of surgery was 59.7 years in the open group and 57.6 years in the arthroscopic group. Results: The Constant score increased from the preoperative mean of 55.9 to 73.2 at the last follow-up in the open repair group and from 53.8 to 67.6 in the arthroscopic repair group (p<0.001 and <0.001, respectively). The University of California at Los Angeles (UCLA) score increased from a preoperative mean of 17.7 to 30.8 at the last follow-up in the open group and from 17.5 to 28.7 in the arthroscopic group (p<0.001 and <0.001, respectively). No statistically significant difference in the Constant and UCLA scores was observed between the two groups at the last follow-up (p=0.128 and 0.087, respectively). Retear was found in 14 patients (36.8%) in the open group and 39 patients (60.9%) in the arthroscopic group (p=0.024). Conclusions: Open and arthroscopic repairs of massive rotator cuff tears may provide satisfactory clinical results with no significant difference. However, a significantly lower retear rate was observed for the open repair group compared with the arthroscopic repair group.

In the past, the report of shoulder instability undergoing open shoulder stabilization had satisfactory outcomes of greater than 90%. However, the functional loss of open procedure is severe in abduction and external rotation especially. Current arthroscopic techniques for shoulder instability result in success rate equal to open surgical procedure when the labrum is properly fixed to the glenoid rim using suture anchors, the capsule is tightened, and associated bony and soft tissue pathology is addressed. The arthroscopic surgery facilitates the view within shoulder joint for more accurate diagnosis, reduces operating time, minimises postoperative pain, reduces operative morbidity, improves shoulder function, and provides the possibility to perform other procedure simultaneously. However, to accomplish a successful arthroscopic stabilization procedure and to prevent complications, numerous advanced arthroscopic skill must be mastered. Although the arthroscope provides means to visualize new lesions, the pathomechanism and biomechanical explanation is not clear yet. Further studies are necessary to develop for shoulder reconstruction.

Arthroscopy is a surgical procedure orthopedic surgeons use to visualize, diagnose and treat problems inside a joint. In usual, since the arthroscopic surgery is more accurate and minimally invasive than through 'open' surgery, the surgery of knee, shoulder, and wrist using auto-shaver is increasing in recent. However, repetitive use of arthroscopic-shaver may induce the second infection, hence the disposable arthroscopic-shaver should be developed. In this paper, a unique power transmission mechanism using DC motor, gear trains, and link mechanism is proposed for disposable arthroscopic-shaver and some test results of tissue cutting are introduced.

Purpose: We reviewed the value of treatment for chronic lateral instability of theankle with arthroscopic procedure combined with Brostrom one. Material and Method: From May 2000 to June 2002, 18 patient with chronic lateral instability of the ankle with Modified Brostrom procedure and arthroscopic one. Mean follow-up period was 18 months. Result: Chronic lateral instability of the ankle almost had intraarticular pathology, such as osteophye, osteochondral lesion, So we could resolve intraarticular pathology by arthroscopic procedure during Brostrom one for lateral collateral ligament reconstruction. Conclusion: Modified Brostrom procedure and arthroscopic one are an excellent treating method for chronic lateral instability of the ankle which has intraarticular pathology.

The open Broström procedure is considered the surgery of choice for treating chronic lateral ankle instability. The role of arthroscopy has gained popularity in the surgical treatment of chronic lateral ankle instability, partly for the ability to manage the intra-articular pathology combined with ankle instability. Arthroscopic techniques can be divided broadly into the arthroscopic-assisted Broström technique and arthroscopic all-inside ligament repair. The clinical results of these arthroscopic techniques are similar to open procedures. The arthroscopic technique may be an excellent alternative to the open Broström procedure in treating chronic lateral ankle instability when applying the appropriate indications.

Purpose : To introduce arthroscopic partial meniscectomy fur bucket handle tear of medial meniscus using posteromedial portal, which is superior to arthroscopic partial meniscectomy using standard anterior portals commonly used. Method : After arthroscopic examination of the knee, we reduce the torn meniscus, advance the arthroscope into posteromedial compartment under arthroscopic visualization, we make posteromedial portal with reexamination of the compartment and perform arthroscopic partial meniscectomy. Conclusion : With the technique of arthroscopic partial meniscectomy using standard anterior portals, accurate partial meniscectomy can not be done because of inadequate visual field, associated meniscal injuries of posterior horn and cartilage lesion of posterior aspect of the medial femoral condyle can be missed, commonly posterior cruciate ligament can be injured and artificial damage to weight bearing surface of medial femoral condyle is possible. An arthroscopic partial meniscectomy using posteromedial portal is an excellent method fur bucket handle tear of medial meniscus.
