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.

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.

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.

Total hip replacement arthroplasty has become an established procedure in the management of painful arthritic hip in past two decades. However there is no many reports that concern follow-up study in total hip replacement arthropiasty. This is a follow-up study in 100 total hip replacement arthroplastics in 86 patients of 157 total hip replacement arthroplasties in 135 patients, performed at the Department of Orthopedic Surgery, Seoul National University Hospital, between November 1973 and December 1979. The longest fallow-up was 5 years and the shortest 6 months, the average being 2 years and 6 months. 1. There were 54 males (63%) and 32 females (37%). 2. The underlying diseases of 100 hips were avascular necrosis of 35 hips, septic hip residua of 31 hips, primary osteoarthritis of 9 hips, old hip fracture of 9 hips, Legg-Perthes disease of 7 hips, rheumatoid arthritis of 5 hips, congenital dislocation of 3 hips, and failed endoprosthesis of 1 hip. 3. The types of prosthesis used were Muller ones in 82 hips, T-28 in 17 hips, and Charniey and Harris type one case respectively. 4. In the half cases of a hundred total hip replacement arthroplasties, the anterolateral or posterolateral approach was used without trochanteric osteotomy. 5. Postoperative complications were as follows: 13 cases of wound problem including 3 early deep infections, 2 dislocations, 1 femoral nerve palsy, 3 peroneal nerve palsies, 1 acetabular perforation, 2 femoral shaft perforations, 14 trochanteric problems including 11 cases of wire breakage, 2 nonunions, and 3 cases of trochanteric bursitis 3 ectopic ossifications, 3 cases of radiological loosening including 2 femoral and 1 acetabular. 6. The range of motion were improved from 28 to 5 of flexion contracture, from 91 to 101 of further . flexion, and from 16 to 48 of abduction in the average. 7. The improved ranges of motion were varied with disease group rather than type of prosthesis and the length of neck of prosthesis. 8. The function of each hip was evaluated preoperatively and postoperatively by the method of Harris and d'Aubigne, and improved from 55.3 and to 88.2 by Harris score and from 11.2 to 15.8 d Aubigne respectively.

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.

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.
