The odontoid process of the ninety axis were measured to observe the morphological features in Koreans. The results are as follows. 1. Height of the ordontoid of process of axis was 14.1±1.3mm, and the degree of the height of the odontoid process to the height of axis was frequency of 38.2±2.6%. 2. Transverse diameter of odontoid process of the most axis (87.8%) was thinner at the lower part than at the upper part. And the difference of the thickness of upper part and lower part was 1.2±0.7mm. In anteroposterior diameter, lower part was thinner than upper part in frequency of 55.6%, and the difference of upper part and lower part was 1.0±0.5mm in the transverse diameter, 0.6±0.5mm in the anteroposterior diameter, therefore the thickness of the anteroposterior diameter. 3. The articular surface of the odontoid process of the axis articulating with the anterior arch of atlas was 8.9±1.7mm in the maximal length and 7.1±1.6mm in the maximal breadth.

In children, snapping knee syndrome and joint pain with the loss of physiological hyperextension strongly suggests a diagnosis of a torn discoid meniscus. We performed arthroscopic meniscectomy to treat torn discoid lateral meniscus on 19 knees and open meniscectomy on 9 knees of 26 children(average age: 10.9 yrs) from September, 1983 to October, 1993 at Guro hospital. According to Ikeuchi's grading system', excellent results were obtained in 14, good in 11, fair in 2 knees and poor in 1 knee which was associated with osteochondritis dissecans. The knees treated by partial meniscectomy showed less Fairbank's radiologic changes than those by total meniscectomy during the average follow-up 4.2 years(minimum 1 year, maximum 7 year 11 months).

The medial collateral ligament is the most commonly injured ligamentous structure of the knee. The management of the medial collateral ligament injuries were divided into surgical and conservative treatment. More recently, many investigators reported that isolated medial collateral ligament injuries did well under non-operative treatment. So, arthroscopic examination of the knee to rule out other intraarticular pathologic conditions such as cruciate ligament injuries, meniscal tear and osteochondral lesion is essential. From October 1993 to April 1995, we treated 45 cases of Grade III medial collateral ligament injuries and arthroscopic finding for cruciate ligament, meniscus, bony structure were analized in these cases. The result were as follows; 1. Anterior cruciate ligament injury:37.5% in +1 degree, 42.8% in +2 degree, 86.7% in +3 degree 2. Posterior cruciate ligament injury:12.5% in +1 degree, 13.4% in +2 degree, 33.3% in +3 degree 3. Meniscal injury:12.5% in +1 degree, 21.3% in +2 degree, 33.4% in +3 degree 4. Medial capsular ligament injury was more frequent and severe in the meniscofemoral ligament than in the meniscotibial ligament, but that finding was not correlated with degree of medial instability.
