The purposes of this study were to document the dimensions of the intercandylar notch in the normal knee; to compare normal knee notches stenosis and femoral intercondylar roof angle to those knees with ACL tears; to compare sexual difference in normal knee to determine if there is a relationship between femoral intercondylar roof angle and notch stenosis and ACL tears. We analyzed 128 MRI of knees taken using the Signa 1.5T MR machine between the ages of 18 and 46 from Feb. 1995 to Feb. 1996. The Group 1 was ninty-one normal knees. The Group 1-F was the normal twenty-two knees of female. The Group 1-M was the normal sixty-nine knees of male. The Group 2 was thirty-seven knees with MRI and arthroscopically confirmed ACL tears within 2 months after injury. We measured the femoral intercondylar roof angle, open notch angle, ratio of notch width at two-thirds of the notch height to condylar width, and ratio of maximum notch width to condylar width from sigittal, transverse cut of MRI. The measurements of the two groups were compared for statistical significance using the student's t-test. Statistically significant differences were found between normal (Group 1) and ACL injured knees (Group 2) in regard to ratio of notch width at two-thirds of the notch height to condylar width, and ratio of maximum notch width to condylar width, but no significant differences were found in the femoral intercondylar roof angle, and open notch angle, suggesting a significant association between anterior outlet stenosis and ACL tears. And statistically significant difference was found only in the ratio of maximum notch width to condylar width between normal male (Group 1-M) and female (Group 1-F), suggesting more stenotic in male group. Although a stenotic femoral intercondylar notch may contribute to a torn ACL, the intercondylar roof angle and open notch angle does not correlate with an ACL tears.

Ganglion cysts on the anterior cruciate ligament should he suspected in any patient having pain and clicking sensation during terminal knee extension. Previous investigators have reported incidental findings of ganglion cysts on the anterior cruciate ligament. We report a symptomatic case of a ganglion cyst on the anterior cruciate ligment that was treated successfully with arthroscopic debridement.

Congenital tricuspid stenosis is an uncommon congenital heart anomaly. Tricuspid stenosis is usually associated with other anomalies, most commonly severe pulmonary stenosis or atresia with secondary hypoplasia of the right ventricle. Clinically it may be difficult to distinguish from tricuspid atresia. A case of congenital tricuspid stenosis in a 32 day-old-girl is presented. The patient had cyanosis and dyspnea. Echocardiographic study revealed tricuspid stenosis with right ventricular hypoplasia, atrial septal defect and pulmonary stenosis.

The elbow is the most frequent area of complaint in children and adolescent baseball players. The physical stresses associated with repetitive throwing create extra-ordinary forces, which may affect the normal osteochondral and soft tissue developmental process and are the important factors causing the decrease of competitive power and shortening of life as a baseball player in adolescents. We surveyed the 114 baseball players of middle & high school in Taegu in order to evaluate the prevalance of symptoms and radiologic findings of the elbow and correlation of these findings to career & position of the baseball game. The results were as follows. 1. Of 114 players, 83 were non-pitchers and 31 were pitchers. The mean career was 3.8 years (7 months to 6 years). 2. The 77 players (67.7%) had the pain on their elbow during or after daily exercise. Other clinical symptoms were locking (30.7%), limitation of motion (18.4%), swelling (16.6%) and clicks on motion (10.5%). 3. On the radiogram of the elbow, hypertrophy or separation of medial epicondyle were seen in 34% of players, loose bodies in 17%, hypertrophy of the humerus in 12% and cystic change of the capitellum in 11%. 4. The mean career of symptomatic players was 4.4 years but non-symptomatics was 2.7 years. The mean career of players who had abnormal radiologic findings was 5.1 years but 3.1 years in players who had no abnormal radiologic fingings. 5. Symptoms and pathologic changes were more common in the elbow of pitcher' s group due to throwing frequency & pitching style. 6. Among the 77 players who had any kinds of problem of the elbow, 49 players of them had no experience of visiting hospital. 7. To prevent these injuries of the elbow, the following recommendations were made. First, restrict the number of innings pitched per game. Second, avoid throwing the curve ball in this age group. Third, ensue an adequate warm up period before exercise or rest after games. Fourth, inform parents and coaches of possible harmful nature of excessive throwing.

Achilles tendon is the most powerful and the biggest tendon of the body and its rupture is frequently sports-related. Many authors reported the effects of mobilization, electricity, ultrasound and various drugs as factors influencing the injured tendon. We studied the effects of early passive mobilization after firm suture using plantaris tendon as tension suture material and reinforcing membrane on the repair of a ruptured Achilles tendon. From March 1992 to December 1995, twenty-two operations on the Achilles tendon were carried out in our hospital. 1. Fourteen patients were male and eight patients were female. The mean patient age was 38 years, ranging from 13 to 68 years. Average follow-up periods was 2 years and 7 months, ranging from 12 months to 3 years and 8 months. 2. The rupture site was 4.7cm proximal to the tendon insertion into the calcaneus on average. 3. We performed the operations with end to end suture technique. After approximation of the ruptured ends of the tendon with a No. 5 Ethibond tension suture using a modified Kessler stitch, placed plantaris tendon in a fascial needle and pass it circumferentially and distal plantaris tendon is fanned out and tacked over the repair. 4. Postoperative treatment was done as following protocol Short leg cast was done with equinus position for initial 3 weeks, and then cast was removed, hydrotherapy and passive exercises was employed. About 6 weeks after operation when the foot can be brought to right angle, a reverse 90degrees ankle stop short leg brace was applied for additional 6 weeks and partial weight bearing was aUowed. 5. Follow-up results were classified according to the Arner-Lindholm scale. We had 16 excellent results and 6 satisfactory results. After rigid suture it may be possible to introduce a regimen of progressive isometric stimulation and protected loading and streching combined with removable orthosis. Such early exercises are likely to improve the rate of rehabilitation over plaster immobilization.

We developed Extor pins for Extor external fixator, it made of stainless steel and applied it clinically to manage open fractures and chronic osteomyelitis from December, 1993 to January, 1995. The main aim of present study is to compare the mechanical strength and biocompatibillity between Extor pins and AO Schanz pins, and to determine the safety and possibility of clinical use. We performed the biomechanical test for bending, tension, and shearing of pin itself using universal testing machine (LR5OK) and pullout test in cadeveric cortical femur to determine the bone holding power. There was no significant difference between Extor and AO Schanz pin (p>0.05). Clinically, the incidence of pin site infection, pin lossening, radiological rarefaction, and pathological change were not different significantly (p>0.05). Although Extor pins are somewhat different from AO Shanz pins in material and design characteristics, we can find the safety and possibility of clinical use of Extor pins made in Korea.

In 1941, Jaffe, Lichtenstein and Sutro collected a group of similar but variously named synovial lesion of joints, bursae and tendon sheaths and gave them the descriptive title “pigmented villonodular synovitis, bursitis and tenosynovitis”. Since then, numerous reports have appeared which further defined the entity or added series of cases in sufficient number to indicate that the lesion is not uncommon. We have experienced a rare case of pigmented villonodular bursitis on bursa anserina. The patient, who were 36 year old, female, has been complained of painful soft swelling on bursa anserina area of right knee for one year. The excisional biopsy on the affected bursa confirmed the diagnosis.
