Purpose : To evaluate clinical outcomes after anterior cruciate ligament (ACL) reconstruction in middle-aged patients and determine the factors affecting the outcome. Subjects and Methods : Clinical results obtained from 60 cases (60 patients) older than 40 years of age at the time of surgery and 58 cases (58 patients) younger than 40 years of age who underwent ACL reconstruction between August 1988 to January 2002, return to sports activity, and stress radiographs using Telos instrument were compared. Results : The Lysholm knee score was improved from the preoperative score of 54.0 points to the postoperative score of 92.9 in patients older than 40 years of age and was improved from 56.2 points to 92.2 points in patients younger than 40 years of age. Clinical outcome was excellent in 51 cases $(85\%)$ and good in 9 cases $(15\%)$ in patients olde. than 40 years of age and was excellent in 47 cases $(81.0\%)$ and good in 11 cases $(19.0\%)$ in patients younger than 40 years of age. There was a significant difference in the rate of returning to preoperative sports activity between patients older than 40 years of age ($60\%$, 36 cases) and younger than 40 years ($82.8\%$, 48 cases). According to Telos stress radiography, the preoperative difference of 11.2 mm was decreased to the postoperative difference of 3.1 mm in patients older than 40 years of age and the preoperative difference of 10.7 mm was decreased to the postoperative difference of 2.9 mm in patients younger than 40 years of age. Clinical outcome did not show significant correlation with age, gender, surgery method, the presence of additional injury, and the rate of return to sports activity before receiving injury (p>0.05). Conclusion : Age didn't have a significant influence on the final outcome of ACL reconstruction and good results could be obtained with ACL reconstruction even in middle-aged patients.

Purpose: To report the clinical results of patients treated for a rupture of the distal tendon of biceps brachii Materials and Methods: Between February 1987 and March 2004, we treated 16 patients with a rupture of the distal tendon of biceps brachii. 9 of 16 patients underwent surgical treatment. All cases were male, median age was 26.3(range, 16-48) years. The mean interval between injury and surgery was 4.7 days (range, 1~36 days). Operative correction was performed anatomically, using the two-incision technique(3 cases) or one-incision technique(6 cases). Clinical outcomes were evaluated one year after operation by assessing the review about the physical examination finding and radiologic findings with surgical findings, range of motion, muscle strength, subjective satisfaction, activity and return to previous occupation. and via telephone interview in cases of conservative treatment. Results: In cases of surgical treatment, 85.8%, 86.3% of flexion-extension and supination-pronation motion than healthy side were measured respectively. 75% of flexion power than healthy side was measured. Eight of nine(89%) were very satisfied. Eightl of nine returned to original job. In cases of conservative treatment, 65% of flexion power than pre-injury state was reported. Four of seven were satisfied, two were dissatisfied, one was very dissatisfied. Three of seven returned to original job. Conclusion: Early anatomic reconstruction can restore more strength and endurance for supination and flexion range and power. Conservative management may be considered for partial injuries, but operative repair must be considered in complete rupture, athletes, patient with high activity.

This study was conducted to investigate the relation between visual analogue scale and recovery time with type of injury that occur in elite wrestling athletes. The incidence rate of injury was analyzed the Poisson ratio, and the VAS and recovery time according to the type of injury were compared using the one-way ANOVA. In addition, the VAS and recovery time were examine the relationship using the Simple Linear Regression, and statistical significance level was α =.05. Injuries occurred most commonly in the ligament, followed by the muscle, cartilage and tendon.The VAS and recovery time according to the type of injury was statistically significant (p=.001, p=.001, respectively). The VAS and recovery time according to the type of injury was statistically significant (p=.001, p=.001). Also, increase in VAS of 1 point was associated with about 1.89 recovery time. These studies are expected to be useful as basic data for return to sports and safe training.

Closed rupture of the extensor hallucis longus (EHL) tendon is uncommon and rarely reported. We present a Taekwondo player who had sustained a closed rupture of the EHL tendon after striking the other player's shin. He had practiced Taekwondo more than 6 hours a day for more than 6 years, including repetitive striking on the dorsum of the foot, which probably caused degeneration of the EHL tendon. The tendon ends could not be approximated directly, so reconstruction was performed with bisecting the distal tendon and combining the repair of the one end with an intercalary scar tissue and the other with tenodesis to the extensor hallucis brevis. He returned to the preoperative level of activity 6 months postoperatively with a satisfactory range of motion.

Purpose: To perform the retrospective analysis of the sports injuries sustained by the college Taekwondo athletes in the respect of the injury patterns, mechanism of injury and clinical outcome Materials and Methods: This study is based on 47 out of 49 college Takwondo athletes, who had experienced the Takwondo related musculoskeletal injuries severe enough to visit the clinic for medical treatment. The mean age at the time of injury was 18.8 years and 39 were males and 8 females. The Taekwondo career was average 9.6 years and the injuries were sustained at average 6.7 years of their career. The injuries were analyzed by the detailed interview with thorough physical examination. Results: Forty-seven Taekwondo athletes in the study experienced average 1.8 injury/person (total 85 cases) with 26 persons of one time experience(55.3%), 11 persons of 2 times(23.4%),4 persons of 3 times (8.5%),5 persons of 4 times (10.6%) and 1 person of 5 times (2.2%). Injuries occurred during training in 50 cases (58.8%), while during match in 35 cases (41.2%). Injuries occurred during the attack phase of the match are 26 cases (31.7%) while 49 cases (57.6%) during the defense phase. As for the pattern of injury, fracture was the most common with 49 cases (57.6%), followed by ligament injury with 21 cases (24.7%). The upper extremity injuries were 32 cases (37.7%) while the lower extremity injuries were 44 cases (51.8%) Mode of medical treatment were operation in 15cases(17.7%), cast in 21 cases(24.7%), splint in 33 cases (38.8%), physical therapy in 15cases(17.7%) and acupuncture in 1 case(1.1%) Conclusion: Almost all the college Taekwondo athletes (96%) experienced sports injuries severe enough to receive medical treatments with the fracture being the most common injury pattern. The injuries occurred more commonly during the defense phase of the competition.

Purpose: To investigate the arthroscopic findings, and to evaluate the clinical outcomes of the treatment of posterior internal impingement of the shoulder in baseball players. Materials and Methods: We followed up 5 cases who were diagnosed as posterior internal impingement for the mean 15 months. All of the cases complained of the pain in the posterior shoulder at late cocking, and were positive in the relocation test added by hyper-horizontal abduction at $120^{\circ}$ abduction of the arm. We sutured posterior labral tear and SLAP lesion arthroscopically, and conducted debridement for rotator cuff. Three cases were performed of anterior capsular plication and the other two were performed of thermal capsular shrinkage. Pain, range of motion, and level of return to sports activity were assessed for the results. Results: As to the arthroscopic findings, all the five cases showed the fraying in posterosuperior labrum, and two of them was accompanied with the flap tear in posterosuperior labrum and the other one was accompanied with type 2 SLAP lesion. All the cases showed the fraying in supraspinatus, and one case showed partial tear. Meanwhile, in all the cases, the rotator cuff was impinged to the labrum at $90^{\circ}{\sim}120^{\circ}$ of abduction and external rotation. As to the postoperative results, all the cases did not complain of pain or instability while pitching, and the competition was recovered to be the mean 88%($80{\sim}100%$) of that before the injury. Conclusion: Definite diagnosis for the posterior internal impingement would be possible through arthroscopic examination. Favorable outcomes could be obtained with capsular plication or shrinkage for anterior microinstability and stretching exercise for posterior capsule tightness inducing the internal impingement.
