To evaluate the value of MR imaging in the examination of ligament injury of the knee, we retrospectively analysed the MR images of 61 injured knees of 60 patients. The presence of tear was determined by arthroscopy in all cases. Anterior/posterior cruciate ligaments(ACL/PCL) were demonstrated by sagittal images. Media/lateral collateral ligaments(MCL/LCL) were evaluated on coronal images. The diagnostic accuracy were 91.8%, 96.7% and 100% for ACL, PCL and MCL, respectively. The specificity for the lateral collateral ligament was 100%. It is concluded that magnetic resonance imaging is an accurate method in detecting injury of the ligaments of the knee.

Recent technological advances have made magnetic resonance images (MR) of the knee a clinical reality. MR is rapidly replacing the conventional arthrography as the imaging modality of choice of the knee joints. To evaluate the diagnostic accuracy of MR in the internal derangement of the knee. MR findings of 244 menisci and 488 ligaments of 122 knees were correlated with those of subsequent arthroscopy or surgery in all cases. The sensitivity, specificity, and accuracy of MR diagnosis for the medial meniscus were 87%, 93%, 91%, for the lateral meniscus 91%, 95%, 93%, for the anterior cruciate ligament 80%, 97%, 92%, for the posterior cruciate ligamant 73%, 99%, 97%, for the medial collateral ligament 67%, 100%, 99%, for the lateral collateral ligament 100%, 100% and 100%. These results imply that MR is an excellent diagnostic modality in the preoperative evaluation of clinically suspected internal derangement of the knee.

The intra-articular tibial plateau fracture can induce many complications of the knee joint after conservative treatment or operative treatment. Recent experience could decrease the complications with accurate anatomical reduction, stable internal fixation and early knee ROM exercise, but still unsatisfactory results were reported from 20% to 40%. The authors analyzed the 30 cases that could be follow-up from 1 year to 6 years and were treated with operative methods, and the following results were obtained. 1. The most common cause of injury was traffic accident (14 cases-46.4%). 2. The most common fracture type by Hohls classification was type VI (13 cases-43.1%). 3. According to Blokker's criteria, 26 cases (86.7%) among 30 cases had satisfactory results. 4. The one of the most important factor influencing end results was thught to be the anatomical reduction of the articular margin.

BACKGROUND: Pneumoconiosis is a parenchymal lung disease that results from the accumulation of coal dust in the lungs and the consequent tissue reaction. To evaluate the role of various personal factors in pneumoconosis and the significance of some serologic markers for assessing the disease activity related to pneumoconiosis, the Rheumatoid Factor(RF), α1-AT, C-Reactive Protein(CRT), ceruloplasmin and fibrinogen levels were measured. METHOD: All the patients were males, 45-76 years old, and the mean duration of coal dust exposure was 23.2 years. 51 patients were classified as having Simple Pneumoconiosis (SP), 59 had Progressive Massive Fibrosis (PMF). Fifty eight men with ages ranging from 26-70 years wer used as normal controls. The serum RF and CRT were titrated using an Autochemistry analyzer (HITACHI 7150 : Japan) and the α1-AT and ceruloplasmin levels were measured using a Nephelometer (Behring Nephelometer : Germany) and the fibrinogen levels were estimated by using and Autoanalyzer for hematologic coagulation. RESULT: There was a higher RF level in the SP, and PMF groups than in the control groups but there was no statistical difference. The CRP, α1-AT, and ceruloplasmin levels were also higher in the SP, and PMF groups. However, the fibrinogen concentration was within the normal ranges in both the SP and PMF groups. CONCLUSION: The CWP (Ed note : Define CWP) patients had significantly higher CRP, α1-AT, and ceruloplasmin levels compared to the control group. It is believed that these serologic changes could be used as a marker of the disease activity.
