INTRODUCTION: The reconstructions of posterior cruciate ligament (PCL) has been increasing because of increased incidence of insufficiency of the PCL and improved surgical skill Arthroscopic operation is known better than open in cruciate ligamet reconstruction in many respects. Arthroscopic PCL reconstruction, especially using hanstring tendon has some benefits. This study is retrospective study analyzing 20 patients treated by arthroscopically assisted PCL reconstruction using hamstring tendon. ALATERIAL AND METHODS: From November 1993 to June 1996, 20 patients with PCL insufficiency had heen treated by arthroscopically assisted PCL reconstruction using double-looped hamstring (semitendinosus and gracilis) tendon by first author. The isometric point was located slightly posterosuperior than anatomic attachment in femur and 0.8-1.0cm below articular margin in tibia. They were confirmed by intraoperative fluoroscopy. The remnants of intact PCL bundle and meniscofemoral ligaments were preserved and added to the graft. They were nineteen men and one women, with a mean age 31.8 years (range, 15-56 years). RESULTS: The results were as follows; 1. The patients were followed from 13 months to 44 months after operation (average 2years and 2months ). 2. Post operative neurovascular irjuries were not found. 3. No revision case was observed and second operations were made in two cases with posterolateral rotatory instability after primary reconstruction. 4. All patient has no symptom of instability after operation. S. At last follow up, Lyshohn knee scores improved from 62 preoperatively to 89 postoperati.vely on average. CONCLUSION: Arthroscopically assisted PCL reconstruction using double-looped hamstring (semitendinosus and gracilis) tendon is easier and less damage than using bone-patellar tendon-bone graft. It preserves intact meniscofemoral ligament, some intact fibers of PCL bundle and quadriceps mechanism. We think it is a effective treatment for PCL insufficiency patients."

OBJECTIVE: Locking of the knee is usually attributed to a tear of meoiscus, or to a loose body that rnechanically obstructs the motion of joint. A less frequently recognized cause of a locked knee is a partial tear of the ACL. The purpose of this study is to report that the partial tear of,the ACL at the femoral attachment site of posterolateral bundle provided a mechanical obstruction in the knW, and it is convicted the injury mechanism of isolated ACL. MATEIRALS AND METHODS: The author presents 16 cases in which the torn ACL was observed knee locking under arthroscopy fram February 1993 to June 1996. Patients ages ranged from 22 to 54 years. The mechanism of injuries were 6 sports activity (Ski 4, Soccer 1, Badminton 1), 4 slip down, 3 pedestrian car accidents and 3 unknown causes with especially low velocity injuries. Although the chief complain in each case was knee pain, all had locking knee that, on physical examination, locked from 5 to 20 of full extension, and 4 locked full flexion. The positive Lachman test was obtained 3 of the 16 paiients. Associated intraarticular injuries were 2 tears of the medial meniscus, 1 lateral meniscus. RESULTS: The average time to arthroscopy was 3 nonths with a range of 1 month to 10 rnonths. An arthroscopic diagnosis and treatment were performed and meniscal tears were ruled out as the cause of locking in all patients. The injury mechanism of isolated ACL was the hyperextensioo of the knee with leg I/R and especially low velocity injuries. The ACL was found to have a partial tear at the site of femoral attachment of an estimated P-L bundle. The torn segment of the ACL to become interposed between the lateral femoral condyle and the latera1 tibial condyle and to act as mechanical block was demcinstrated. CONCLUSION: In all cases, the torn portion of the ACL was excised under arthroscopy and knee locking was resolved.

In contrast to the nodular renal blastema which is defined by nests of primitive metanephric cells after 36 weeks of gestation, the nephroblastomatosis is characterized by neoplastic proliferation of the primitive cells. This lesion is presumed to be closely related to the development of Wilms' tumor. We report a case of bilateral nephroblastomatosis associated with Wilms' tumor in a child. This 4 1/2 year-old girl was admitted because of a 10 cm-sized round mass in the right kidney, and smaller nodules in the left kidney and the lung. After three cycles of chemotherapy and subsequent disappearance of the nodules in the left kidney and lung, she underwent a right nephrectomy and a wedge resection of the left kidney. A round Wilms' tumor mass was seen in the lower pole of the right kidney. Remaining right renal cortex showed multiple, slightly depressed gray-white nodules associated with multiple samll cysts. They were comprised of multifocal subcapsular nests of primitive nephrogenic cells with focal tubular or glomerular differentiation. They resembled fetal renal tissue. In the left kidney, similar nests of primitive cells were also noted. These lesions were interpreted as multifocal perilobar type of nephroblastomatosis.

BACKGROUND: Treatment of adult patent ductus arteriosus(PDA) has many difficulty such as pulmonary hypertension, arterial wall calcification, aneurysmal chage of ductus. We tried to evaluate the effect of surgical interruption of PDA on postopeative change of heart size. MATERIAL AND METHOD: From 1987 to 1997 we experienced 30 cases of the ligation of patent ductus arteriosus in adult at the department of cardiovacular surgery in Masan Samsung General Hospital. RESULT: There were 9 males and 21 females and their ages ranged from 16 to 44 years, with a mean age of 26.1 years. 15 patients had pulmonary hypertension and 9 patients complained of dyspnea with a degree of functional NYHA class III. Operation method was double or triple ligation using Teflon felt. Postoperative complications were wound dehiscence in 3 patients and transient hoarseness in 1 patient. The mean preoperative cardiothoracic ratio was 54.7%, and mean postoperative cardiothoracic ratio was 51.9%. The change of cardiothoracic ratio was more typical in the cases who had congestive heart failure. Their mean preoperative cardiothoracic ratio was 64.8% and the mean postoperative cardiothoracic ratio was 58.5% there was no postoperative deaths. CONCLUSION: We canclude that the improvement in cardiothoracic ratio may result from surgical intervention of PDA.

BACKGROUND: The aim of the Long-term Care of Older People via Incheon Nursing Home Network (LOVE) study was to evaluate disease status and its association with physical activity and emotional status among the elderly in nursing homes. METHODS: This retrospective study included 1,379 nursing home residents aged 65 years and older, of which 260 were excluded due to lack of baseline information. Data regarding major diseases from 1,119 people were analyzed to compare prevalence according to age. Data about physical function and emotional status on admission from 497 residents were analyzed looking for contributing factors to limited function and unstable emotion. RESULTS: Hypertension was the most common ailment at 58.6% of the total followed by dementia (50.6%), stroke (28.7%), and diabetes (24.2%). Prevalence of diabetes (p<0.001) and stroke (p<0.001) were relatively low in the older age groups but that of osteoarthritis (p<0.001) and dementia (p=0.001) were relatively high. After adjusting for age and sex, limited physical activity was more frequent in those with strokes (odds ratio [OR], 3.7 [2.1-6.2], p<0.001) and fractures (OR, 2.1 [1.1-4.1], p=0.023). Unstable emotion was more frequent in residents with dementia (OR, 1.9 [1.3-2.8], p=0.001). CONCLUSION: The most common diseases among nursing home residents, in decreasing order, were hypertension, dementia, stroke, and diabetes. Diseases related to the need for physical aids were strokes and fractures. Effective strategies for the management of unstable emotional status in the elderly with dementia are needed.
