The aim of this study was to determine whether there are quantitative changes in the mechanoreceptors in the anterior cruciate ligament of unstable knee with injured medial articular cartilage or medial ligament. Twenty specimens of anterior cruciate ligament were obtained from medial articular cartilage injury group and medial ligament injury group, respectively. Forty anterior cruciate ligaments of the other side of knee were used as controls. The ligaments were transected and stained with a modified gold-chloride method. Mechanoreceptors were located almost exclusively in the periligamentous synovial tissue. The results were as follows; 1. Three kinds of mechanoreceptors were found at the surface of each ligament beneath the synovial membrane. 2. The type 2 mechanoreceptor was more common than any other types in all groups. 3. In the medial articular cartilage injury group, the number of mechanoreceptor was significantly decreased and morphologically degradated with synovial degeneration than the control group. The same findings were noted in the medial ligament injury group(P<0.003). 4. There was no statistical difference between the two experimental groups in numher of the mechanoreceptor. In conclusion, the mechanoreceptor of the anterior cruciate ligament of unstable knee with injured medial articular cartilage and ligament in the rabbit were decreased in its numher and were degradated morphologically than the control group. And it was suggested that reduced proprioception in unstable knee might he an another cause of development of osteoarthritis.

A microvascular osteocutaneous free flap is totally detached from its origin and reattached at a distant site, in one stage, by the use of microvascular anastomosis to maintain its viability. The advantages of microvascular osteocutaneous free flap trsnsfer are more rapid healing, greater resistance to infection, less risk of absorption than conventional bone grafts, and shortened hospitalization. Two cases of microvascular osteocutaaeous free flap transfer were performed at the department of Orthopaedic surgery of Hanyang University Hospital, and satisfactory results were obtained.

PURPOSE: This study was to describe the burden of aged parents caring for adult children with disabilities and related factors. METHODS: The subjects were 123 caregivers aged over 65 who were caring for 18-year-old or older children with disabilities. The research tool of this study was a structured questionnaire on family burden. Data were collected from June 3 to 25, 2010, and analyzed by Cronbach's alpha, mean, standard deviation, t-test, and ANOVA using SAS 9.2 program. RESULTS: The major findings of this study were as follows. Elderly parents caring for adult children with disabilities perceived a moderate level of burden. The burden from concern over their children's future was highest, and economic and physical burdens were higher when the parents were younger. Burden was significantly different according to parents' characteristics such as gender, perceived health status, disease, the costs of caring for disabled children, and children's characteristics such as disability rating, health status, and ADL. CONCLUSION: In order to reduce the burden of elderly parents caring for adult children with disabilities, we need to improve their health status and assess comprehensive policies.

We evaluated the role of endoseopic balloon dilatation for esophageal strictures caused by postoperative anastomosis in 5 cases, sclerotherapy in 4 cases, caustic injury in 6 cases, and malignancy in 16 cases. The success rate of balloon dilatation was 100% in postoperative anastomotic and post-scle- rotherapy strictures, 16.7% in caustic stricture, and 62.5% in malignant stricture. The addition of bougienage increased the final success rate of dilatation therapy from 16.7 to 66.7% in caustic stricture, and 62.5 to 93.8% in malignant stricture. The overall one-year recurrence rate in benign stricture was 34.5%. All of the recurrent strictures were successfully retreated by balloon dilatation. In conclusion, endoscopic balloon dilatation is a safe, effective, and easy method for the management of benign esophageal strictures except longstanding caustic stricture, and can be used as an auxiliary therapy prior to more definitive treatments such as esophageal intubation in malignant stricture.

The 6 patients with neglected rupture of the Achilles tendon were treated by end to end anastomosis using the V-Y tendinous flap originated by Abraham in 1975. A tendinous flap was developed over the tendon by making an inverted V incision, which was then repaired in a Y fashion. The postoperative results were satisfactory with no functional disability of the ankle and with recovery of muscle strength for periods of 8 months to 15 months, but slight limited dorsiflexion of the ankle in two cases were noticed. The advantages of this method are: 1. Optimum functional recovery. 2. Recovery of muscle strength and tendon contour. 3. Prevention of late stretching or possible rupture of the healed tendon at the rupture site.

9 Cases of femoral head fractures treated in Seoul National University Hospital were reviewed. They were classified according to Pipkin, and assessed according to Ebstein's criteria. The longest follow-up was 3 years and the shortest 6 months, the average being 1 year and 6 months. l. 8 cases were injured due to auto accident and there was no one who had worn seatbelt. 2. 1 case of intestine rupture and 2 cases of homothorax were accompanied. 3. There were 1 excellent, 1 good, and 1 poor results in 3 cases of Pipkin type 1, 1 fair result in 1 case of Pipkin type 2, 1 good and 1 fair results in 2 cases of Pipkin type 3, 1 good and 2 fair results in 3 cases of Pipkin type 4. 4. The following complications were encountered, 2 cases of sciatic nerve palsy, 1 case of avascular necrosis of femoral head, 1 case of traumatic arthritis.

It is well known that the incidence of revision arthroplasty for the loosened total hip has been progressively increasing recently. And the problem is that the loosening rate of revision arthroplasty for the failed total hip replacement is much higher as compared with that of primary total hip replacement. In revision arthroplasty, Amstutz, in 1982, reported 9% incidence of mechanical failure and 43% incidence of femoral and 61% incidence of acetabular progressive radiolucencies with follow-up for an average of 2.1 years, and Pellicci, in 1985, reported 29% incidence of failure for total hip replacement that have been revised once in the radiolucent zone with the follow-up for an average 8.1 years, and Kavanagh, in 1985, reported that probable loosening occurred in 25% of revised acetabular components with follow-up for an average of 4.5 years. Cementless total hip replacement is successful in more than 90 of the primary cases for the last 5 years in our department. Therefore, not only in primary total hip replacement but also in the revision, it seems to be reasonable to perform the cementless total hip replacement as an alternative, particularlly, in young age group. During the period from April 1982 to December 1984, we have revised 12 loosened total hip replacement with cementless type. Average follow up was 1 year and 7 months. The age range of the patients was 23 to 64. The results are very promising without any evidence of loosening in all cases.

One hundred eighty-eight patients with avascular necrosis of the femoral head in adults, who were admitted and treated in Department of Orthopedic Surgery, Seoul National University Hospital between January of 1965 and May of 1985 are investigated in terms of the history, clinical data and laboratory examinations. And, the following results were obtained. 1. The incidence was higher in the 5th decade and the sex ratio between male and female was 3.3:l. 2. 106 cases (56%) had the bilateral hip involvement. 3. The most frequent etiological factor was alcohol (72 cases, 38%), followed by trauma (35 cases, 19 %), and steroid (32 cases, 17%). 4. Underlying diseases in steroid-induced avascular necrosis of the femoral head were dermopathy (9 cases), nephropathy (4 cases), pain over other joints (5 cases), systemic lupus erythematosus (2 cases), etc. 5. The time intervals between etiological events and appearances of clinical symptoms were 2 years and 3 months in the steroid induced cases, 1 year and 1 month in trauma induced ones, 2 years and 1 month in femur neck fracture cases, 2 years and 2 months in Caissons disease, and 3 years in post-irradiation 6. Bone scan was valuable in the early diagnosis of avascular necrosis of the femoral head. 7. Selective femoral head angiography show narrowing of lateral femoral circumflex artery, narrowing or obstruction of medical femoral circumflex artery, and obstruction of superior retinacular artery. 8. It is suggested that minor trauma and osteoporosis could make micro-fracture, resulting avascular necrosis of the femoral head, and the vascular change is secondary to the avascular necrosis.
