We studied 25 cases of patients with anterior knee joint pain without any other knee problems with a isokinetic evaluation technique using Cybex. The results are 1. The peak torques for the knee extensor muscles were decreased statistically 2. The peak torques for the knee flexor muscles were decreased relatively also but not statistically 3. TAE(Torque Acceleration Energy) values for knee extensor & flexors were all decreased from disuse atrophy 4. The torque curve for extensors showed decreased power around 30 degrees of knee flexion

Authors has analysed bone mineral density(BMD) of spine and proximal femur of 55 normal male patients who visited Dankook University hospital, college of medicine from may 1994 to February 1995. The aims of the study is the investigation of correlation between BMD and age distribution and the change of the BMD. 1. The ages of maximal BMD from the 2nd lumbar spine to the 4th lumbar spine exist between 26 years old and 30 years old. The average decrease rate of BMD is 5% per 10 years from the age the maximal BMD. 2. Te BMD of the 12th thoracic spine and 1st lumbar spine is lower than that of the average BMD from the 2nd. to 4th lumbar spine. 3. The correlation cofficient of the lateral projection with anteroposterior projection is 0.632 at the 2nd lumbar spine and 0.500 at the 3rd lumbar spine. 4. The ages of maximal BMD of proximal femur exist between 21 years old and 25 years old. The average decrease rate of BMD is 7% per 10 years from the age of maximal BMD.

Study Design : Spine fusion with fixation procedure is associated with substantial operative blood loss, which frequently necessitates transfusion. The authors evaluated the safety and efficacy of intraoperative autotransfusion using Cell Saver during spinal surgery. Summary of Literature Review : It has been reported that the contraindications to the use of intraoperative autologous transfusion are malignancy, infection, and gross wound contamination. Objectives : The purpose of this study was to evaluate the safety and efficacy of intraoperative autotransfusion using Cell Saver during spine surgery. Material and Methods : We retrospectively reviewed 62 patients who had operation for lumbosacral spinal stenosis and hypotensive anesthesia. Among them, Group Ⅰwhich received autotrans fusion using Cell Savers included 26 patients with fusion of 2 segments, and Group Ⅱ as control group included 13 patients. Group Ⅲ which received autotransfusion using Cell Savers included 17 patients with function of 3 segments, and Group Ⅳ as control group included 6 patients. We analyzed the amount of intraoperative blood salvage using a Cell Saver, the amount of total homologous transfusion amount, intraoperative blood loss, the amount of postoperative drainage amount and perioperative changes of hemoglobin, hematocrit and platelet count. Results : There was no statistical significance between Cell-Saver group and control group in amount of total homologous transfusion and intraoperative(except in 2 segment of fusion using cell saver: 86.5% increased) & postoperative blood loss(p>0.05). The circulatory balance(amount of intraoperative blood salvage using a Cell Saver plus amount of total homologous transfusion minus amount of total blood loss) was statistical significance between Cell-Saver group and Control group. The Cell-Saver group had positive balance and Control group had negative balance. There were no statistical differance in the evolusion of hemoglobin, hematoocrit and platelet count between Cell-Saver group and Control group(p>0.05). There was no transfusion reaction and thromboembolic disease in all group. Conclusion : In retrospective study, Cell Savers was safe and immediate availability in orthopedic surgery such as spinal surgery. It was effective methods for storing a sufficient volume of blood for spine surgery without affecting the patient's postoperative hemodynamic ststes, too. It was possible to operation without intraoperative homologous blood transfusion in 2 or 3 segment fusion. We may need further study.

Normal feet have the longitudinal arch for the distribution of the weight. The longitudinal arch is known lateral and medial longitudinal arch. Collapsed arch of the foot is flat foot and it is the cause of the foot pain. Of course the low arch does not always make a foot problem in sports and daily activity. Longitudial foot arch is visible in the standing foot lateral radiograph, Harris mat and visual observation. In Radiographic study the lateral Talo-lst Metatarsal angle is known in standing foot lateral film. But the longitadinal medial arch is not correctly obtained in Talo-lst Metatarsal angle. So this study for Calcaneo-lst metatarsal angle in standing lateral foot radiograph is more valuable angle in medial longitadinl arch. And we do the study on difference in the longitadinal arch in normal weight versus overweight person.

The purpose of operative treatment in thoracolumbar spine fractures is anatomical reduction and stabilization of the fractures and thus promote neurological recovery and early rehabilitation. To achieve these goals, complete preoperative assessment and recognition of the fracture pattern is necessary in addition to good surgical technique. The authors analyzed 27 cases of thoracolumbar spine fractures operated from Jun. 1994 to Dec.1995 at the Department of orthopaedic surgery, Dan-kook University Hospital. All cases were analysed according to McAfee classification. In deciding the appropriate surgical approach, fracture pat-tern, stability and neurologic status were considered. The result were as follows; 1. Unstable burst fracture, 11 cases, was the most frequent type. 2. 1st lumbar fracture was the most common level in this series. 3. Fall down, 15 cases out of 27, was the most common cause on thoracolumbar spine fracture. 4. Anterior approach was performed in 8 cases and posterior approach was performed in 19cases. 5. Good results were obtained through firm fixation and early rehabilitabion.

Purpose : Shortening of the patellar tendon after ACL reconstruction has been one of the causes of postoperative complieations such as anterior knee pain, patellar baja syndrome because of that reason, donor tendon defect was not closed generally. It took at least two years far the tendon to fill the gap by regenerated tendon tissue. But, sometimes protrusion of infra-patellar fat pad may prohibit the regenera-tion of patellar tendon, This study was designed to assess the amount of actual tendon shortening after tendon closure and complications because of it. Material and Methods: Thirty-two cases of arthroscopically assisted midthird patella tendon autograft ACL reconstruction were studied. Patella tendon defect was closed in all cases and the follow-up duration was more than 12 months. The patellar tendon length was measured before and after the defect site closure in operating room, Also, radiolagic tendon length changes were assessed using Insall-Salvati technique. Result: The mean patellar tendon length that had been measured in operating room was 51.5mm, 49.8mm (before and after the tendon defect closure). So, the mean shortening was 1.71mm(3.3%). The mean LT/LP ratio was 0.922, 0.894, 0.898(pre-operative and post-operative 6months, 12months). so, the radiologic mean shortening was 3.0%(6months), 2.6%(12months). There were only 4 cases of anterior knee pain and other complications were not found. Conclusion: Patellar tendon length change after donor tendon defect closure was about 3% and there were no complications associated with it.
