Purpose: To research match injuries related to Taekwondo in adolescent athletes and find out preventing injuries. Materials and Methods: We analyzed 162 match injuries of middle and high school athletes, who were surveyed in 2005 and 2006 national tournament. Results: Among 162 match injuries, injuries in foot and hand were the most common and there were 35 cases in serious injuries such as fracture, open dislocation, open fracture of epiphyseal plate and so on. The very fast speed and destructive power of Takwondo athlete can cause open dislocation of great toe and can cause fracture of foot and upper extremity when kicking. Conclusion: We consider that injured athletes need proper treatments and sufficient rest not to accumulate training injuries and match injuries and need to improve mats of stadium, braces for feet and hands and put on braces for elbows to prevent match injuries.

Multiple ligament knee injury is defined as rupture to at least two of the four major knee ligament structures. Three or four knee ligament injury results in knee dislocation as complete disruption of the integrity of the tibiofemoral articulation. In multiple ligament knee injury, vascular and neurologic assessment should be performed meticulously and systematically. Emergency surgery should be needed if arterial injury is suspected. Surgical treatment rather than conservative management should be done and early surgery might be better than delayed surgery. Reconstruction of ACL and PCL, repair or reconstruction of MCL, and reconstruction of posterolateral corner are recommended, although many debates have occurred. Multiple ligament knee injury requires more aggressive management than single ligament knee injury.

Purpose : The purpose is to analyze the relationship between bone bruise in MRI and associated injuries after the knee joint trauma. Materials and Methods : Total 50 cases were reviewed, divided into two groups according to initial trauma energy. High-energy group (group I), such as traffic accident was 13 cases, low-energy group (group II), such as sports trauma was 37 cases. The type of the lesion was used the classification by Costa-Paz. The site of lesion was analyzed according to femoral/tibial, medial/lateral and anterior/middle/posterior site respectively. Associated injuries were confirmed by physical examination, radiograph, MRI and arthroscopy. Results : In group I there was a various distribution of the bone bruise in the knee joint according to mechanism of injury. The bone bruise with ACL injury was 38$\%$ only and the most frequent type was Costa-Paz type I (52.6 $\%$). In group II more frequent locations were the middle portion of the lateral femoral condyle and the posterior portion of the lateral tibial condyle. Bone bruise associated with ACL injury, was upto 56.8 $\%$ and the frequent type were Costa-Paz type II (48 $\%$), in order type I (42 $\%$). As a result, in the high-energy injury the bone bruise had a various location in both condyle and less frequently associated injury, but in the low-energy injury there was particularly frequent location of bone bruise, associated injury and type. Conclusions : We could assess the associated injury by analysis of the location and type of bone bruise, especially in the low-energy injury, e.g. sports injury. But further study will be necessary with more case analysis.

The motions used in throwing place tremendous stresses on the soft tissues about the player's shoulder. In order to throw successfully, the shoulder complex must be capable of excessive motion, while maintaining stability of the glenohumeral joint. Injuries to the throwing player can result from acute trauma, but more commonly can be a result of overuse injuries from the repetitive throwing activity. Inbalance in the muscles and soft tissue about the shoulder can result in an injury secondary to abnormal biomechanics of the glenohumeral complex. The preventive measure a throwing player can take in order to maintain a healthy throwing shoulder is to participate in a regular shoulder strengthening program. It is when the muscles about the shoulder become imbalanced, secondary to either injury or relative weakness, that instability and injury can occur. By understanding the pitching motion and the relative contribution of the muscles, the treating physician has a framework on which to build knowledge regarding physical findings and diagnosis of shoulder injuries in throwing players. Once a diagnosis is made. a successful treatment plan may be developed for the player, including both conservative and , at time surgical means.

Purpose: The purpose of this study was to analyze the characteristics of the injuries of the national elite Taekwondo players with the best performance in the international championship competition. Materials and Methods: Fifty-two athletes who got the injury in the 2011 Gyeongju World Taekwondo Championship competition were included in this sturdy. 950 members of national team of 146 countries participated in this game, 1,063 matches were performed. We analyzed the characteristics of the injuries such as injury rate by gender, age, weight class, injured region and injury type. Results: Fifty-two athletes of 950 athletes in 1,063 matches got injured and injury rate was 5.47 per 100 participants and 24.47/1,000 athlete-exposures. Injury rate of female athletes was higher than mail, but there was no significant statistical difference (p=0.512). Injury rate of over 30 years old was 17.39 per 100 participants, and injury rate of over 87 kg in male weight class and 68 to 73kg in female weight class were highest than other groups, but there was no significant statistical difference (p=0.838). Overall injury rate of the lower extremity was 13.17/1,000 A-E, higher than upper extremity or head and neck or trunk, but injury rate of the hand was 5.17/1,000 A-E, highest as a specific injured region, followed by the knee, 4.70/1,000 A-E (p=0.714). Injury rate of the sprain was 10.81/1,000 A-E, highest as an injury type, the second most common injury type was the fracture, 5.40/1,000 A-E in men, and was the contusion, 9.63/1,000 A-E in women (p=0.033). As one of the most serious injury, 4 of 8 fractures were occurred in hand. Conclusion: Overall injury rate of the elite Taekwondo players in 2011 Gyeongju World Taekwondo Championship was 5.47 per 100 participants and 24.46 per 1,000 athlete exposures. Although the most common type of injury was the sprain of the knee and ankle, the fractures were more commonly occurred in hand.

Purpose: The purpose of this study was to determine how many of our patients who had had anterior cruciate ligament (ACL) reconstruction returned to their previous levels of sports and to identify why not doing so. Material and Methods: We evaluated 43 knees with a minimum of two years follow-up among whom undergoing 109 ACL reconstruction from September 2003. The mean age of patients was 26 years (17 to 45 years) Clinical results was evaluated according to the Lysholm Knee scores, Tegner activity score, subjective IKDC questionnaires, objective IKDC evaluation form and KT-1000 arthrometer. Results: The overall clinical results demonstrated significant improvement at the final follow-up comparing to preoperative data (P<0.05). Among 43 patients, 25 patients (58%) returned to their previous level of sports and 18 patients (42%) did not. Of whom, 11 patients (61%) were not able to return to sports due to fear to re-injury and 7 patients (39%) suffered from instability and pain. The differences in the Lysholm Scores, KT-1000 arthrometer and subjective IKDC in the 3 groups of patients by ANOVA test were found to be statistically significant (P<0.001). Although there is no difference in objective IKDC and KT-1000 arthrometer, the difference was observed in Tegner activities, subjective IKDC obtained by those who returned to sport and those who had fear to reinjury (P<0.001). Conclusion: This study showed that a quater of patients could not return to their previous level of sport after ACL reconstruction because of fear to reinjury. We thought that not only improving the technique of ACL reconstruction and systemic rehabilitation but also considering psychological factor of patients could allow more patients to return to the previous level of sports.
