The present study was carried out to investigate the relationships between the depth of overbite and the masseteric silent period Normal subjects of 44 were selected, which consisted of 9 open bites, 24 normal overbites and 11 deep bites, all were 19-29 years of age EMG activity was recorded on the bilateral masseteric muscles and craniofacial radiography was done. The following results were obtained 1. The mean duration of masseteric silent period was 18.58+/-4.50 msec in open bite, 17.37+/-7.05 msec in normal overbite and 19.30+/-7.62 msec in deep bite groups. 2. There were no significant differences on masseteric silent period among open bite, normal overbite and deep bite groups. 3. There were no significant correlations between masseteric silent period and craniofacial variables.

The tibiofemoral angle is widely used for the diagnosis and treatment of knee problems, especially in degenerative joint disease of the knee. Among the various methods of measurement of tibiofemoral angle, Bauers method is being used most frequently. But measurement by Bauers method has seemed to show wide individual differences. Therefore we designed a ruler which can be used very easily for the measurement of the tibiofemoral angle with little differences between persons who measure the angle. To testify the advantages of our method, we selected 4 orthopedic surgeons and let them measure the tibiofemoral angles of 60 knees of 30 patients by Bauers method and by our method using the ruler. And 20 orthopedic surgeons measured tibiofemoval angles of 2 left knees by Bauers method and by our method using the ruler. The values of the tibiofemoral angle by two methods were compared and analyzed statistically. There was no significant differences between mean values. But, the tibiofemoral angles by our new method showed little differences among measurers. (P < 0.05)

The menisci or semilunar cartilages of the knee provide the function of mechanical lubrication and they are particularly important in allowing rotational movements of the knee joint. The study was carried out on 123 Korean adult knees for measurement of the menisci and observation of surrounding ligamentous structures through anatomical dissection of formalin embalmed cadavers. Detection of abnormal meniscal lesions was also included in this study. The following results were obtained: 1. A-P diameter, transverse diameter, maximal width and thickness were measured in 123 knees of 62 cadavers. 2. Among 62 cadavers,' the anterior menisco-femoral ligament was present in 11 subjects (17.7%), the posterior menisco-femoral ligament in 59 (95.2%), and the transverse ligament in 36 (58.0%). 3. Discoid lateral meniscus was found in 5 knees (4.1%), and tear was associated in 3 of them. 4. Meniscus tear was found in 13 knees (10.6%), and the site of tear was medial in 9 knees and lateral in 4 including 3 torn discoid menisci. The oblique pattern of tear was most common.

Recurrent dislocation of the patella is a relatively uncommon disease, which is most commonly seen in females in late adolescence. The condition is usually spontaneous and only rarely fallows traumatic dislocation. Dislocation is nearly always lateral and about one thirdis bilateral. The theoretical rationale of the treatment of the recurrent dislocation and subluxation of the patella is the realignment of the extensor mechanisms. We experienced with recurrent dislocation and subluxation of the patella on 22 knees in 18 patients at Seoul National University Hospital from July 1981 to Oct. 1987 and obtained the following results. 1. The age at operation ranged from 4 to 33 years and its mean was 15.8 years. Among 18 patients thirteen were female and five, male. 2. The most common presenting symiptom was pain (11 knees) and the most common presenting sign was quadriceps muscle atrophy (11 knees). 3. The prominent radiologic finding was patella alta in 6 knees (27.3%), genu valgum in 10 knees (45.3%), and hypoplasia of the lateral condyle of the femur in 2 cases (9%). 4. In two knees supracondylar osteotomy were performed and followed by proximal extensor mechanism realignment. In twelve knees only proximal reconstruction was performed. Four knees were treated by Hauser's technique and three knees with Roux-Gold-thwait technique. And these distal reconstruction procedures were performed with other procedures. 5. Mean follow up period was 1 year and 5 months. And the results are excellent in 8 knees, good in 12 knees and fair in 2 knees.
