Many types of meniscal anomalies have been reported. The authors encountered two cases of anomalous insertion of the anterior horn of the medial menisci to the lateral femoral condyle which ran along the course of the anterior cruciate ligament(ACL) without connecting ACL. These anomalies were noted during arthroscopic surgery of the ipsilateral knee for a torn discoid meniscus, and a patellar fracture. A 34-year-old woman had a horizontal tear of the lateral discoid meniscus. We performed arthroscopic partial meniscectomy of the inner torn portion of the lateral discoid meniscus and contoured it to resemble a normal meniscus. An anomalous insertion of the medial meniscus was found on examination of the joint during surgery. A 32-year-old man had a patellar fracture and we performed reduction under arthroscopy and internal fixation with cannulated screws. The same anomalous insertion of the medial meniscus was found on examination of the joint during surgery. We report the cases with review of literature.

We analyzed 41 cases of burst fractures on the thoracolumbar junction which were operated with Kaneda and Cotrel-Dubousset implant at Chosun University Hospital between 1989 and 1993. The purpose of this study was to evaluate the radiologic sign, the amount of reduction, complications, and functional results. The results were as follows: 1. According to McGrorys Criteria to evaluate the posterior superior vertebral body angle of burst fractures, 33 out of 41 cases(80.5%) were positive and the average angle degree was 107.6°. 2. The average postoperative kyphotic correction was 15.4° in the Kaneda group and 13.8° in the C-D group. The average loss of correction at follow-up examination was 5° in the Kaneda group and 4.8° in the C-D group. 3. Indirect reduction was achieved in 10 cases(50%) and we obtained a good indirect reduction even though canal compromise was over 50%. 4. The pain at operative site was much more severe in the Kaneda group(6 cases) than in the C-D group(2 cases) and both groups experienced 2 cases each of implant failure. 5. According to Denis' pain and work scale, 28 cases(63.8%) had good and excellent, 8 cases had fair and 5 cases had poor results. In summary we recommend doing 1) a posterior instrumentation first for stability and indirect reduction, if it is not a severe neurologic symptom and 2) anterior decompression if it is a severe or progressive neurologic symptom.

Nineteen cases out of over 100 cases which had been reconstructed the deficient anterior cruciate ligament(ACL) by the bone-patellar tendon-bone(BPTB) autograft 12 months before or more(mean 15.8 months) were evaluated during the second-look arthroscopy. Before the second-look, the patients were evaluated the clinical results of ACL reconstruction by the Müller's knee rating score and the radiographical results by the lateral roentgenography of the fully extended knees. The location of the center of tibial tunnel from the anterior end of the line of the tibial plateau was 35.2%(range, 22 to 47%) on average. The average intercondylar roof angle was 36.6 degrees(range, 28 to 45 degrees). The mean percentage of roof impingement was

Authors analyzed the findings of nineteen cases of arthroscopic second-look operations after posterior cruciate ligament (PCL) reconstruction with autogenous bone-patellar tendon-bone (BPTB) and Trevira augmentation by two tunnel technique during the period from Nov, 1993 to Jan. l997 in fifty-one cases, along with the results of reconstruction in terms of clinica1 knee scoring, radiographichl and arthroscopic findings. The results were as follows; Age ranged fmm 20 to 53 years, the average being 32.3 years. Thirteen cases (68%) had associated knee injuries; five medial collateral ligament (MCL) injuries, four lateral collateral ligament (LCL) injuries, two associated injuries of MCL and medial meniscus, one both menisci and one associated injury of anterior cruciate ligament and MCL. The average period fmm PCL injury to reconstruction was 7 weeks (range, 1 to 52 wecks) and the mean period from PCL reconstruction to second-look operation was 20.3 months (range, 10 to 46 months). The average Miiller s knee score at the last follow-up was 86 paints. The radiographical results: The distance of posterior translation of the PCL reconstrueted knee compared with the normal sidc knee in posterior stress roentgenography was average 3.8mm (range, 0 to 1 1 mm). The position of the fernoral bone block on the plane of extended Blumansaats line, from the anterior end of the line, was average 32%. The level of proximal end of the tibial bone block according to the tibial tunnel orifice into the joint was mean negative 2.6 degrees position. The findings of arthroscopic second-look examination; In 9 cases (47%), the reconstructed ligamcnts were well covered with synovial tissue and looked like almost normal PCL. There were five cases (26%) of severe fragmentation, three cases (16%) of partial torn fibers of the grafted tendon. And one case showed the thinning of thc grafted tendon compared with the initial diameter at the time of reconstruction and one case showed overgrawth of the synovial membrane which suitounding the grafted tendon. All the Trevira which were augmented at the time of PCL reconstruction were ruptured. Twelve cases (63%) were stable, three cases (16%) were slightly lax and 4 cases (21%) showed laxity of the grafted tendon by the posterior drawer test and probing under arthroscopy, The isometricity which was checked at the time of PCL reconstruction was average 3.4mm. From the ahove results, PCL reconstruction with autogenous BPTB by the two tunnel technique seemed to be a valuable procedure, but there were some cases of unfavorable results. Authors think that a new graft fixation method is needed for resolving the problem mentioned above.

Between December 1994 and December 1996, 42 patients underwent arthroscopic meniscal repair in our institute. Among them, 31 patients with a follow up more than one year were reviewed. Mean age was 24.4 years(range, 18-52 years) and mean interval between onset of symptom and opera- tion was 12.3 months(range, 3 days-6 years). The associated injuries were tibial plateau fracture(6 cases), anterior cruciate ligament injury(4 cases) and posterior cruciate ligament injury(2 cases). The type of tear were longitudinal in 28 cases(90%) and combined in 3 cases(10%). Most of the meniscal tear were encountered in posterior hom(12 cases, 39%) and middle portion(11 cases, 35%). Out side to in technique was used in anterior horn tears and inside to out technique in middle or posterior hom tears. In tibial plateau fractures, arthroscopic assisted reduction was performed with autogenous bone graft. Ligament reconstructions were performed in the cases of associated cruciate ligament injury. According to Ikeuchis grading system, the result was satisfactory(excellent or good) in 23 cases(74%), fair in 6 cases(19%) and poor in 2 cases(6%). But in the cases of isolated meniscal injury, the result was satisfactory in 95%. The result of arthroscopic repair in the meniscal tears associated with other intra-articular injuries seems to be worse than that of the isolated injuries.

Fractures of the capitellum humeri are rare and the recommendations for treatment vary. It can involve a significant portion of the articular surface, rendering the elbow joint unstable. In this situation, it is desirable to reduce and internally fix the capitellar fragment, because this restores the articular surface and augments joint stability. We experienced two cases of capitellar fractures which one case was spontaneously anatomical reduced and the other case was treated by open reduction. In one case the capitellar fragment was spontaneous reduced to a stable position although it was noticed radiographically as an unstable displaced fracture preoperatively. The other case was treated by open reduction and internal fixation with 3.5mm, small, AO, cannulated screw and K-wire. Both cases are reported here with references.

OBJECTIVE: Recently, microdissection of tissue sections has been used increasingly for the isolation of morphologically identified homogeneous cell populations, thus overcoming the obstacle of tissue complexity for the analysis cell-specific expression of macromolecules. The aim of the present study was to establish the minimal conditions required for the RNA extraction and amplification from the cells captured by the laser captured microdissection. METHODS: Mouse ovaries were fixed and cut into serial sections (7 micrometer thickness). Oocytes were captured by laser captured microdissection (LCM) method by using PixCell IITM system. The frozen sections were fixed in 70% ethanol and stained with hematoxylin and eosin, while the paraffin sections were stained with Multiple stain. Sections were dehydrated in graded alcohols followed by xylene and air-dried for 20 min prior to LCM. All reactions were performed in ribonuclease free solutions to prevent RNA degradation. After LCM, total RNA extraction from the captured oocytes was performed using the guanidinium isothiocyanate (GITC) solution, and subsequently evaluated by reverse transcriptase -polymerase chain reaction (RT-PCR) for glyceraldehyde-3-phosphate-dehydrogenase (GAPDH). RESULTS: With the frozen sections, detection of the GAPDH mRNA expression in the number of captured 25 oocytes were not repeatable, but the expression was always detectable from 50 oocytes. With 25 oocytes, at least 27 PCR cycles were required, whereas with 50 oocytes, 21 cycles were enough to detect GAPDH expression. Amount of the primary cDNA required for RT-PCR was reduced down to at least 0.25 microl with 50 oocytes, thus the resting 19.75 microl cDNA can be used for the testing other interested gene expression. Tissue-to-slide, tissue-to-tissue forces were very high in the paraffin sections, thus the greater number of cell procurement was required than the frozen sections. CONCLUSION: We have described a method for analyzing gene expression at the RNA level with the homogeneously microdissected cells from the small amount of tissues with complexity. We found that LCM coupled with RT-PCR could detect housekeeping gene expression in 50 oocytes captured. This technique can be easily applied for the study of gene expression with the small amount of tissues.
