Purpose: The purpose of this study was to evaluate the result of anterior cruciate ligament (ACL) reconstruction using a fourstrand single semitendinous tendon to decrease the donor site morbidity due to harvest both semitendinosus and gracilis tendon. Materials and Methods: Thirty seven consecutive patients who had underwent ACL reconstruction using four-strand single semitendinosus tendon were evaluated. Mean age was 28.6 years old. Male was 34, female 3 patients. Time from injury to surgery was 5.4 months. Combined injuries were 10 meniscus injuries, 3 medial collateral ligament injuries and 1 osteochondral injury. Mean follow-up period was 16 months(12~18 months). Clinical evaluation was done using range of motion, Lachman test, pivot-shift test, Lysholm score & KT-2000 arthrometer. Results: All patients showed the normal range of motion of mean 150..at follow-up. Lachman test and pivot-shift test was negative in 35 cases. Lysholm score was improve from 84 to 92. Two cases had residual laxity due to poor compliance. Mean anterior translation compared to contralateral side by KT-2000 arthrometer improved from 6.7 mm preoperatively to 2.1 mm at follow-up. Conclusion: Reconstruction of the anterior cruciate ligament with use of a four-strand single semitendinosus tendon autograft showed good clinical results.

Displaced tibial spine fractures need the anatomical reduction of the displaced bone fragment to achieve normal range of motion and anterior stability of the knee joint. The purpose of this paper is to describe details of arthroscopic technique using suture hook and pull-out PDS and to evaluate the clinical results. We report 7 cases who underwent arthroscopic reduction and internal fixation using suture hook and pull-out PDS. All cases had fresh fractures generated within 3 weeks. The follow up period was at average 16.6 months. The fracture union was achieved at average 7.4 weeks. Knee exercise was started 2 weeks after the operation. One of the patients, who had combined injury of posterior cruciate ligament and lateral meniscus, showed limitation of knee movement. But he was underwent the arthroscopic fibrolysis at one year later, he returned to normal range of motion. Arthroscopic treatment of displaced tibial spine fracture using suture hook and pull-out PDS showed good results including rigid fixation and early mobilization. Therefore it is thought to be one of the effective operative techniques in treatment of the tibial spine fractures.

Purpose : The purpose of this paper is to analyze the clinical results after meniscal repair using meniscal arrow. Materials and Methods : Between May 1997 and Aug 1998, we repaired 22 tom menisci in 22 patients using meniscal arrows. There were nineteen males and three females with an average age of 27 years. There were longitudinal tear in 14 cases, Bucket-handle tear were 7 cases and horizontal tear was in 1 case. In 22 meniscus tears, 16 cases were associated with anterior cruciate ligament tear. Average number of meniscal arrow that was used were 2.5(ranged 1 to 4). Average follow-up period was 14.7 months(ranged 6 to 22 months). We evaluated the clinical results by the Tapper and Hoover's grading system. Results : There were excellent in 16 cases, good in 4 cases and fair in 2 cases on the clinical results. At the last follow up, the range of the motion of the knee joint were average 135 degrees(ranged 125 to 140 degrees). Mean time elapsed for meniscal repair were 25 minutes(ranged 15 to 40 minutes). Conclusion : Meniscal arrow has many advantages such as short operative time, easy fixation technique, and less neurovascular injury. We think that arthroscopic meniscal repair using meniscal arrow is effective treatment method in selected patient who have longitudinal, bucket-handle tear at the posterior hom associated with anterior cruciate ligament tear.

Purpose : To evaluate tile clinical results of resorbable meniscal arrow fixation for repairable meniscal tear with concurrent anterior cruciate ligament(ACL) reconstruction. Materials and Methods : Between April, 1997 and June, 1999, we performed resorbable meniscal arrow fixation and ACL reconstruction simultaneously for 18 cases of repairable meniscal tears with ACL injuries. Nine cases were acute injuries, 5 cases, subacute and 4 cases, chronic. The average follow-up was 21.5 months($12\~38$ months). Results : The healing rate was $89\%$ for acute injuries, $80\%$ for subacute injuries and $50\%$ for chronic injuries. Conclusion : Resorbable meniscal arrow fixation with concurrent ACL reconstruction is a good treatment modality for acute and subacute injuries.

Purpose: This study is to analyze the clinical and radiological results after arthroscopic reduction and internal fixation of intra-articular fractures of lateral tibial plateau. Materials and Methods: The subject of the study are the 13 cases of the patients visited orthopedics surgery during March year 2000 to August year 2004 because of intra-articular fractures of lateral tibial plateau and were treated with arthroscopic reduction and internal fixation. X-rays and CT or MRI were both carried out to identify the precise pattern of fracture and the degree of depression which showed out to be all type 2 by Schatzker fracture classification. And in 9 of the cases, autogenous and allogenous bone grafts were given as bone loss were severe. The average age was 48, age group between 31 and 66, and average follow up period of about 38 months ($13{\sim}65months$). Radiological ratings were given by comparing the X-rays of degree of joint congruency before and after the operation, functional ratings by analyzing IKDC score and Lysholm score. Combined injuries observed after arthroscopy were posterior cruciate ligament injury in 1 case, meniscus injury in 4 cases and medial collateral ligament in 2 cases. Results: During follow up, X-rays showed well-maintained reduction of articular surface in all cases and no complications such as joint depression, fracture reduction loss, angular deformity or malunion were found. Average Lysholm score at last follow up was 87 points ranging from 65 to 97, in 8 of the cases excellent, 3 good, 1 fair and 1 poor according to Lynsholm classification. Average IKDC score was 92 (from 82 to 99). Conclusion: Not only does arthroscopic reduction of lateral tibial plateau fracture bring exact reduction of articular surface, but also, is considered to be a good way of operation to diagnose and treat combined injuries of knee joint using arthroscopy.
