Torn discoid lateral meniscus has been numerously reported in diagnosis and treatment. But discoid meniscus in children of which clinical pictures were thought to be different from adults was rarely known. We experienced 2 cases of discoid meniscus tear in children whose ages were below 4 years old and report with references.

Arthroscopy of the knee joint is an essential diagnostic procedure of the knee joint lesions because of its high diagnostic accuracy and simple procedure and high safety. We analysed in 300 cases of knee joints arthroscopy which performed in Kyung Hee University Hospital from July 1978 to June 1982. The results were as follows: 1. The diagnostic accuracy of clinical diagnosis of knee joint lesions based on arthroscopic findings was 51.0%. 2. The diagnostic accuracy of clinical diagnosis in surgically confirmed cases of knee joint lesions was 56.1% and diagnostic accuracy of arthroscopy was 90.9%. 3. In meniscal lesions, the diagnostic accuracy of arthroscopic diagnosis was 94.5%, arthrographic diagnostic accuracy was 84.9%, clinical diagnostic accuracy was 48.9% and combined accuracy of three diagnostic methods was 97.3%. 4. In cases which diagnosed as I.D.K. (Internal Derangement of Knee) in initial stage of knee joint lesions, meniscal lesions (32.8%) and ligament injuries (22.4%) were predominant lessions based on arthroscopic findings. 5. The frequency of meniscal tear were no significant difference in lateral (33.3%) or medial (36.0%) meniscus except discoid meniscus rupture. 6. 68 Cases of 300 arthroscopies (22.7%) were avoided unncessary arthrotomy through preoperative arthroscopic examination of knee joint. 7. Arthroscopy is very useful and essential not only to confirm the diagnosis but also to treatment of knee joint lesions.

This study was performed to establish a radiological indication and contraindication of indirect decompression in the thoracolumbar burst fracture as well as to clarify an acceptable degree of the canal constriction to enhance neurologic recovery and to prevent the spinal stenosis. The canal diameter ratio (CDR) of the constricted level was determined using pre-and post-operative CAT images of 31 thoracolumbar burst fractures, decompressed indirectly. The acceptable CDR was decided by the lower limit of the 95% confidence interval of the post-operative CDR in cases without neurologic deficit associated with the canal constriction. A radiological indication and contraindication of indirect decompression was establish based on the calculation of the discriminant equation and linear regression equation respectively. The results were as followings. 1. The acceptable CDR was 46% at the cauda equina level and 37% at the conus medullaris level. 2. According to the result of calculation of the regression equation, the radiological contraindication of indirect decompression was the pre-operative CDR of 13% or less at the cauda equina level and 27% or less at the conus medullaris level. In conclusion, the radiological indication of indirect decompression was the pre-operative CDR of 34% at the cauda eqbina level and 42% at the conus medullaris.

In the orthopaedic field, some elective surgeries such as joint replacement, spinal surgery and limb salvage procedures for musculoskeletal tumors frequently need various amounts of blood transfusions. However, homologous transfusion occasionally results in various side effects, such as allergic reaction, febrile reaction, and the transmission of infectious diseases such as syphilis, hepatitis and AIDS, ctc. Recently, these complications especially in elective surgery might result in medicolegal or social problems. Risks from transfusions in elective surgery can be minimized with prebanked autologous transfusion. To evaluate the necessity of prehanked autogenous transfusion, fifty five patients who had unilateral hybrid total knee arthroplasty (noncemented at the femoral side and cemented at the tibial and patellar sides) were operated on by the same surgeon from April 199S to July 1997 and had autogenous shed blood transfusion were evaluated for postoperative blood loss, amount of autogenous shed blood, amount of transfusion, hemoglobin and hematocrit. The results were as follows: 1. The distribution of preoperative hemoglobin was from 9.6g/dL to 16.5g/dL (average: 1.8g/dL). 2. The distribution of the amount of blood loss for three days postoperatively was from 156ml to 2001 ml (average: 798ml). 3. The distrihution of the amount of transfusion of autogenous shed blood was from 30ml to 600ml (average: 448ml). 4. There were two patients who had febrile reactions above 38 after transfusion of autogenous shed blood. 5. Forty-six patient(84%) had a homologous transfusion and the average amount of transfusion was 1.9 pint. 6. Total amount of homologous transfusion was decreased according to the increased amount of hemoglobin and the amount of transfusion was statistically decreased above the level of I 3g/dL(Students t-test, P=0.0005). 7. There were no significant differences in the amount of homologous transfusion between age, sex, type of disease, type of implants. In conclusion, most of our patients(84%) needed homologous blood transfusion in unilateral hyhrid total knee arthroplasty and the amount of transfusion decreased in patients who had hemoglobin above 13.0g/dL. So we recommend preparing banked autogenous hlood preoperatively in patients who have a lower hemoglobin level in unilateral hyhrid total knee arthroplasty.
