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.

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.

Radiographic increase in the size of tibial and femoral tunnels has been observed following the reconstruction of the ACL with a bone-patellar tendon-bone autograft. The purpose of this study is to determine if any differences exist in the amount of enlargement of the bone tunnel with the clinical results and to know the factors which affected to the enlargement of the bone tunnels. Total 27 patients were retrospectively reviewed for tunnel enlargement radiographically at one year after operation. Anteroposterior and lateral x-ray were obtained and the tunnel were measured by two independent observers. The measurements were made at the widest part of the tunnel. The distance between tibial interference screw and knee joint line also measured. Correction for magnification was performed by comparing the measured width of the interference screw used for fixation of the graft with its actual width. Statistical analysis was performed with Wilcoxon rank sum test. The radiographic tunnel enlargement was an average of 1.7+/-1.3mm for the femur and 1.9+/-0.8mm for the tibia. The proximal migration of the tibial interference screw was an average of 2.3++/-1.1 mm. There was no statistically significant correlation between the changes in tunnel diameter and either the modified Hughston knee score, Lysholm knee score, or the joint laxity measured by a KT-2000 arthrometer, Lachman test. There were no correlations between the mild proximal migration of the tibial interference screw and the clinical results. Conclusively, the tunnel enlargement and mild proximal migration of the interference screw did not appear to affect the functional outcome adversely. It needs longer follow up for the evaluation of etiology and natural history of this tunnel enlargement.

The purpose of this study was to evaluate the amount and interrelationship of the soft and hard tissue change after mandibular setback surgery in skeletal Class III malocclusion. The sample consisted of 25 adult patient (12 male and 13 female) who had severe anteropostrior skeletal discepancy. These patient had received presurgical orthodontic treatment and surgical treatment which is bilateral sagittal split ramus osteotomy. The presurgical and postsurgical lateral cephalograms were evaluated. The computerized statistical analysis was carried out with SPSS/PC program. The result were as follows: 1. After mandibular bilateral sagittal split ramus osteotomy, lower facial soft tissue horizontal posterior changes were high significance value. but vertical soft tissue changes were low significance value. 2. After mandibular bilateral sagittal split ramus osteotomy, relative upper lip protrusion increased(p<0.01) and relative lower lip protrusion decreased(p<0.01) and lower facial soft tissue thickness increased(p<0.01).

With simple abdomen, double contrast colon study, and ultrasongraphy, authors retrospectively analyzedradilogic findings of 46 cases which were proved periappendiceal abscess, due to perforation of appendix, byhistology or follow-up ultrasnongraphy from May in 1983 to July in 1985 at Yeung-Nam University Hospital. Theresuls obtained were as follows: 1. Of 46 cases, 24 cases were males and 22 cases females, with the results ofabove statistics, periappendiceal abscess was not influenced by sex. 2. Periappendiceal abscess was mostfrequently demonstrated in forties. 3. Comparison of ultrasonography and B.E. Pseudorenal pattern(Ultrasonography)- well defined defect (B.E.) Cystic pattern(Ultrasonography)- serrated defect (B.E.) 4. Missed 2 cases inultrasonography were detected in B.E., i.e. sensitivity of B.E. is higher than that of ultrasonography. 5.Differences of ultrasonography and B.E.
