The surface electromyographic(sEMG) analyses were knee joint angle during open kinetic chain exercise (OKC) and close kinetic chain exercise (CKC) in vastus medialis (VM), vastus lateralis (VL), and rectus femoralis (RF). Ten subjects with normal , aged 20 to 30(X=27.4, SD=3.23), were randomized Statistical techniques for data analysis were applied paired t-test. The 0.05 level of significane was used as the critical level for rejection of the null hypotheses for the study. And the results were: 1) Both OKC and CKC improved the strength of quadriceps muscle as the knee joint flexion was increased. 2) In OKC, the strength of VM was improved the most at the 30 degree angle. 3) In CKC, the strength of VM was improved the most at the 30 degree angle. 4) The VM/VL ratio was the largest at the 10 and 20 degree angles in OKC and CKC. 5) The VM/VL ratio at 10, 20, and 30 degree angles was significantly different between OKC and CKC (P < 0.05). Base on the results, the OKCE is recommended for the knee joint patients, especially for the patellofemoral pain syndrome patients, during the early phase of rehabilitation. In order to improve strength of the quadriceps, muscle strength training at 30 degree angle is recommended. In order to improve VM/VL ratio, 10 and 20 degree angles are recommended during OKCE and CKCE, respectively. Future researches are warranted comparing electromyographic analysis between OKCE and CKCE in the quadriceps at a certain work lead, and muscle strength performance in the quadriceps at different positions of foot.

Purpose: The purpose of this study is to evaluate the results of arthroscopic anterior cruciate ligament(ACL) repair with minimal incision and to review prognostic factors according to ACL tear patterns and the presence of associated injury Materials and Methods: Thirty eight patients (thirty nine knees) with acute ACL tear were given arthroscopic ACL repair between January 2001 and December 2002 and were followed up at least over six months. Intraoperative findings such as ACL tear pattern and the presence of synovial or concomitant medial collateral ligament injuries were recorded. Each knee was then postoperatively re-evaluated with aid of KT-1000 arthrometer and Lachman test and Lysholm score. Results: Postoperative limitation of motion was significant when combined typed ACL tear was present with concurrent medial collateral ligament(MCL) injury. In contrast, in the case where there were sole proximal ACL tear or no evidence of synovial injury, the limitation of motion was not significant. Anterior laxity was significantly associated with the presence of combined typed ACL tear or concurrent synovial injury, but was not significant when there were sole proximal ACL tear. Conclusion: In the case where there is sole proximal ACL tear without concurrent synovial injury, arthroscopic ACL repair can be considered as a treatment modality for the treatment of acute ACL injury.

This study performed a proprioception improvement training for recurrence prevention of industrial workers with chronic lateral epicondylitis and analysed their pain and proprioception. The subjects of the study were thirty chronic lateral epicondylitis patients working for K company and were divided into elbow exercise program Group made of 15 subjects and proprioception improvement training Group made of 15. As variables for pain, pressure pain, and grip strength were measured and for the propioception, joint position sense of each group was measured before and after the exercise program. To compare differences before and after the program, a paired t-test was used and to compare differences between both groups, an independent samples t-test was used. As a result of the test, it was discovered that pressure pain, grip strength and joint position sense of the both groups were improved statistically significantly. These were statistically differential effect between each group on pressure pain, grip strength and joint position sense. In conclusion, it is suggested that proprioception improvement training should be considered as a method chronic and recurrence prevention lateral epicondylitis of industrial workers.

This study was undertaken to document the clinical results and technical aspects of arthroscopic repair including popliteus tendon as a post for the treatment of complex lateral meniscus in young people indicated as total meniscectomy. From June 2004 to May 2006, we prospectively studied arthroscopic repairs on 32 young people knees with symptomatic complex lateral meniscus that was treated by all inside repair technique using Popliteus tendon as a post. Clinical results were evaluated using Lysholm knee scores preoperatively and at final follow-up. 2nd look arthroscopy or MRI was taken at final follow-up. 80% of patients carried out MRI or 2nd look arthroscopy under permission. Most patients who follow up were able to return to their previous life activities with little or no limitation, and no reoperation was required after an average follow-up of 42.8 months. Mean Lysholm knee scores improved from 65.4 (range, 55 to 75) preoperatively to 93.9 (range, 79 to 100) at the final follow-up (P<.001). 80% meniscus healing was found on arthroscopic or MRI follow up. Conclusively, arthroscopic repair using Popliteus tendon as a post is effective for treating young people with complex lateral meniscus tear as a salvage procedure.

The nonlinear finite element program has been developed to analyze the design performance of an artificial hip prosthesis and long term behavior of a treated femur with stems made of composite material after cementless total hip arthroplasty(THA). The authors developed the three dimentional FEM models of femoral bone with designed composite stem which was taken with elliptic cross section of 816 brick elements under hip contact load and muscle farce in simulating single leg stand. Using the program, density changes, stress distributions and micromotions of the material femoral bone were evaluated by changing fiber orientation of stems for selected manufacturing method such as plate cut and bend mold. The results showed that the composite materials such as AS4/PEEK and T300/976 gave less bone resorption than the metallic material such as cobalt chrome alloy, titanium alloy and stainless steal. It was found that increasing the long term stability of the prosthesis in the femur could be obtained by selecting the appropriate ply orientation and stacking sequence of composite.

Purpose: This study aimed to investigate the effects of a nurse-led community comprehensive exercise program on the body composition, physical function, and health-related quality of life in elderly patients with osteoporosis. Method: The study was conducted with one group pretest-posttest design. A total of 57 elderly patients participated in 8 weeks of intervention. Data was analyzed with the SPSS ver. 23.0 using descriptive statistics and paired t-test. Results: At the end of the intervention, body mass index was significantly increased (t=2.93, p=.005), but right leg balance (t=2.40, p=.02) was significantly improved. In addition, the total Korean-Western Ontario and McMaster Universities Osteoarthritis Index (K-WOMAC) (t=3.48, p=.001), knee pain (t=2.61, p=.012), stiffness (t=2.53, p=.014), and physical function (t=3.51, p=.001) were significantly decreased. EuroQoL Visual Analogue Scale (EQ-VAS) scores (t=4.25, p<.001) were significantly improved. Conclusion: The nurse-led eight-week community comprehensive exercise program did not show desirable change in the body composition but was effective on the physical function and health-related quality of life for older people with osteoartritis.

Most patients experience pain relief and functional improvement after arthroscopic rotator cuff repair. In some patients, however, symptoms still remain after surgery. Failed rotator cuff repair is a complex outcome of biological, technical, and traumatic factors. Moreover, re-tears might or might not be the main cause for patients with persistent pain after rotator cuff repair. Therefore, a thorough understanding of the patient's history, physical examination, and appropriate imaging studies will be needed to evaluate and manage these patients. The patient's age, functional requirement, quality of the rotator cuff, preoperative range of motion, quality of the deltoid, and glenohumeral arthritis are factors to consider before performing revisional rotator cuff repair. Preoperative patient education is as important as the surgical technique for successful revisional rotator cuff repair.

This study was performed to provide detailed and comprehensive information on inflammation-related blood indicators, joint range of motion, pain scale, and psychological indicators by patient characteristics by performing a 12-week home-based exercise program for ankylosing spondylitis patients. For the purpose of this study, 10 patients with ankylosing spondylitis were selected by age (30s vs. 40s vs. 50s), gender (male vs. female), and duration (less than 5 years vs. 5 years or more). The home-based exercise program was a combination of aerobic exercise and Pilates-based resistance exercise, and was performed 4 times a week for 12 weeks at an intensity of 50-70% of maximal heart rate (MHR). As a result, after 12 weeks of home-based exercise intervention, the blood C-reactive protein (CRP) concentration of patients with ankylosing spondylitis decreased (-35.6%, p=.002), and the blood inflammation level was improved, and each joint (hip, lumbar, cervical) improved mobility (p<.05). In addition, the bath ankylosing spondylitis disease activity index (BASDAI) was decreased by -67% (p=.001) and the visual analogue scale (VAS) was decreased by -64.8% (p=.001), stiffness and pain has been alleviated. In particular, as the degree of depression decreased by -65.5% (p=.001) and the degree of anxiety by -55.2% (p=.003), 12 weeks of home-based exercise improved not only physical changes but also psychological factors. On the other hand, there was no difference in exercise effect according to age, gender, and disease duration in ankylosing spondylitis patients (p>.05). These results suggest that the 12-week home-based exercise applied in this study can be an effective exercise program that can be universally used for ankylosing spondylitis patients regardless of patient characteristics.
