Double contrast arthrography has been widely accepted as a method to diagnose the internal derangement of the knee. It is a safe and technically simple procedure permitting accurate diagnosis of lesions of the menisci. In 20 cases operated upon, with the diagnosis of internal derangement of the knee, we performed double contrast arthrography before surgery. We analysed the cases concerning the diagnostic accuracy of arthrography, its clinical significance and discrepancies between arthrographic findings and postoperative lesions. The results were as follows: 1. The cases consisted of 16 cases of meniscal lesion, 4 cases of ligamentous lesion and 3 cases of loose body. 2. In the meniscal lesions, 14 of the 16 cases (87.5%) were diagnosed accurately by arthrography, Therefore arthrography was more useful in diagnosing meniscal lesions as compared with clincal symptoms (69%). 3. In cases of ligamentous lesions arthrography was not significant-ly helfpful, in contrast clinical signs afforded important clues. 4. We encountered 1 case of false positive and 1 case of false negative.

The value of double contrast arthrography in meniscal lesions was studied in 58 patients with clinical findings suggestive of meniscal lesion. In all cases, arthrotomy was performed and meniscal lesions were found in 52 patients. The arthrographic findings were compared to clinical and operative findings and the following results were obtained. 1. The diagnostic accuracy of arthrography in meniscal lesions was 84.5% 2. The diagnostic accuracy of the clinical findings was 69%, but the accuracy was increased to 91.4% with the aid of arthrographic findings. 3. Arthrography would be unnecessary if the clinical findings highly suggest the meniscal lesion. 4. Arthrography is thought to be a useful diagnostic method for meniscal lesions.

Accompanying to the development of the knowledgment of mechanism and pathology of recurrent dislocation of the shoulder, accurate diagnostic tools to detect that pathology have been developed. During the period from May 1990 to May 1992, we treated 28 cases of recurrent anterior dislocation of the shoulder. Twenty-eight cases were examined with C.T. arthrography before the operation. Among the 28 cases, we identified the Bankart lesion in 20 cases by C.T. arthrography, and in 21 cases intraoperatively. We concluded that the C.T. arthrography is an accurate method for confirming the clinical diagnosis of recurrent dislocation of the shoulder and to be helpful in detecting the Bankart lesion and its severity or pathologic findings.

We applied arthroscopy in the diagnosis of thirty four patients with internal derangement of the knee from March to August, 1982. Its results were compared with clinical diagnosis and arthrographic findings. We also performed arthrofomy in twenty nine patients and the final diagnosis enabled us to evaluate the diagnostic accuracy of each method. The accuracy of clinical diagnosis was 63.4%. Arthrographic findings were correct in 77.8%. The diagnostic accuracy of arthroscopy was 92.3% with one false negative case. Unnecessary operations were avoided in five patients with the assistance of negative findings of arthroscopy. Arthrography and arthroscopy were complementary in the diagnosis of internal derangement of the knee.

In planning treatment of tibial condylar fracture, the patient's age and physical condition, associated ligament injury and accurate fracture diagnosis, such as presence and degree of separatiori of split fragment, type of fracture and the severity of comminution must be considered. For accurate diagnosis, many kinds of methods including simple X-ray, arthroscopy, arthrography and tomography can be used. In spite of these procedures, sometimes we cannot know the accurate fracture morphology. The computed tomography(CT) has many advantages over other diagnostic methods. The application of CT in the evaluation of patients with spinal and pelvic fractures has been established, but rarely has its usefulness been noted in tibial condylar fracture. We thought that in assessing tibial condylar fracture, CT is more useful and accurate than conventional radiography. From March 1985 to August 1986, we took 17 patients(18 cases) of tibial condylar CT and were convinced with that it is a good diagnostic method. The results are as follows: l. In 5 cases, we could find a new fracture on CT film, which was impossible to be detected on simple X-ray. 2. In 7 cases, the fracture classification by plain X-rays was changed after CT check-up. 3. We could make the decision of treatment methods easily through more realistic classification and better recognition of split and comminution. 4. Proper approach could be done by understanding the accurate fracture size and localization.

Femora acetabular impingement (FAI) is thought as the major reason leds to hip osteoarthritis. FAI results to destruction of the arthrodial cartilage. Prognoses of hip osteoarthritis is affected by the degree of arthrodial cartilage destruction. The hip osteoarthritis could be prevented if FAI is diagnosed and treated in earlier period. How can we diagnose FAI in earlier period? Recent studies showed that MRI was the best way for FAI diagnosis. It has higher resolution and signal-noise ratio. Cartilage and gleniod labrum of hip could be shown by MRI. The paper reviewed the standard and difficulties of diagnosis about FAI. High magnet MRI maybe is one way to solve the problems.

OBJECTIVE: To compare inferior capsular redundancy by using magnetic resonance arthrography (MRA) images in patients with multidirectional instability (MDI) of the shoulder and control subjects without instability and thereby develop a screening method to identify the presence of shoulder MDI. MATERIALS AND METHODS: The MRA images of patients with MDI of the shoulder (n = 65, 57 men, 8 women; mean age, 24.5 years; age range, 18–42 years) treated over an eight-year period were retrospectively reviewed; a control group (n = 65, 57 men, 8 women; mean age, 27.4 years; age range, 18–45 years) without instability was also selected. The inferior capsular redundancy was measured using a new method we named the glenocapsular (GC) ratio method. MRA images of both groups were randomly mixed together, and two orthopedic surgeon reviewers measured the cross-sectional areas (CSAs) and sagittal capsule-head ratios on oblique sagittal images, as well as the axial capsule-head ratios on axial images and GC ratios on oblique coronal images. RESULTS: The CSAs and GC ratios were significantly higher in patients than in controls (both, p < 0.001); however, the sagittal capsule-head ratios and axial capsule-head ratios were not significantly different (p = 0.317, p = 0.053, respectively). In addition, GC ratios determined the presence of MDI more sensitively and specifically than did CSAs. A GC ratio of > 1.42 was found to be most suggestive of MDI of the shoulder, owing to its high sensitivity (92.3%) and specificity (89.2%). CONCLUSION: GC ratio can be easily measured and used to accurately screen for MDI of the shoulder.

OBJECTIVETo investigate the method of MR guided anterior direct arthrogaphy of shoulder and its clinical applications.

METHODSFrom 2008.4 to 2008.10, 40 patients with rotator-cuff tear (29 males and 11 females, ranging in age from 22 to 70 years, with an average of 35 years) underwent MR guided anterior direct arthrogaphy of shoulder, so as to diagnosis shoulder wound. The results were compared to that of arthroscopy.

RESULTSShoulder arthrography showed lesons in 36 patients, and failure in 2 patients, including contrast media extravasation in 1 patient, and gas entry to joint cavity in 1 patient. Two patients showed no rotator cuff injuries. Twenty-eight patients were confirmed by arthroscopy as rotator-cuff injured in different degree. Twenty-six patients were confirmed injuries by both arthroscopy and MR guided anterior direct arthrogaphy.

CONCLUSIONMR guided anterior direct arthrogaphy of shoulder as a minimally invasive method in displaying the rotator-cuff tear has higher accuracy and wide clinical application prospect.

Legg-Perthes' disease, as avascularity of the femoral head that often arises in the child of a particular age group, is a serious disease of which the frequency is more than the osteochondroses of the other part, and the cause of Legg-Perthes disease is obscure up to now, but the pathogenesis and, pathology are more clearly understood. Twenty patients with Legg-Perthes disease were managed at the department of Orthopaedic Surgery of Hanyang University hospital from May, 1972 till September, 1977 and were studied according to the method of Catterals classification arid arthrogram. The following conclusion were made. 1. The age group with the highest frequency was that from 6 to 9 years (40%) and the ratio of male: female was 6: 1. 2. The stage of disease s progress when patient went to hospital was almost fragmentation stage as 17 persons of the whole. 3. By arthrogram Spherical form of femoral head was 15%; Round form 45%; Flatten form 40%. 4. The longer the period from onset to beginning of treament was the more femoral head flattened. 5. There was the most number of patient as 13 persons of the whole wearing abduction internal rotation brace. 6. From the view point of arthrogram the more spherical the femoral head was the better the prognosis was; otherwise the worse.

OBJECTIVETo explore the diagnostic value of 3D-indirectmagnetic resonance (MR) arthrography in detecting meniscustears of the knees.

METHODSForm January 2013 to January 2014, routine plain MR of the knees followed by the 3D-indirect MR arthrography was performed in 42 patients with suspected meniscal tears clinically. There were 31 males and 11 females, with an average age of 38.4 years old (ranged, 21 to 67 years old). The duration of the course ranged from 2 h to 15 d. The clinical symptom was knee pain. All the patients got subsequently arthroscopic examination or operation. The sensitivity and specificity of routine plain MR and 3D-indirect MR arthrography were compared based on the results of arthroscopic examination or operation.

RESULTSThe signal intensity in the area of meniscal tears on image of 3D-indirect MR arthrography was obviously higher than that of routine plain MR. The sensitivity of 3D-indirect MR arthrography was 85.79% (87/102), while the routine plain MR was 52.94% (54/102), and the specificity improved from 67.78%(61/90) to 86.67%(78/90). The difference was statistically significant (χ2 = 25.90, P < 0.01; χ2 = 9.13, P < 0.01).

CONCLUSIONIn comparison with the routine plain MR findings, 3D-indirect MR arthrography demonstrates meniscus tears of the knee with the better sensitivity and specificity.
