When we see normal gait, gait cycle is seperated as stance phase and swing phase. It needs 6 determinant of gait of pelvic rotation, pelvic tilt, knee joint of stance phase, ankle and foot motion, ankle and knee motion, and pelvic movement to be accomplished. In addition, a joint and muscle action is accomplished biomechanically at the same time with its gait cycle. In oriental medicine, the relationships between chang-fu physiology and meridian physiology are summaried as follows ; ${\bullet}$ chang-fu physiology : Spleen manages the extremities. Liver manages soft tissues. Liver stores blood. Kidney stores essences. Kidney manages bones. ${\bullet}$ meridian physiology : The Leg Greater Yang Meridian and meridian soft tissues The Leg Yang-Myeong Meridian and meridian soft tissues The Leg Lesser Yang Meridian and meridian soft tissues The Leg Greater Yin Meridian and meridian soft tissues The Leg Lesser Yin Meridian and meridian soft tissues The Leg Absolute Yin Meridian and meridian soft tissues Especially, we can find out relations between in a "blood supplied feet can walk well" that explains "blood regulations and by liver nourishing effects"that is the closest concept of muscle. Abnormal gaits are due to three causes as following; first, physical defect secoud, pain third, nervous system or instability of muscle. In oriental medicine, we can know relationship in "atrophy, numbness, stroke, convulsion, muscular dystrophy of knee, rheumatoid arthritis, five causes of infantile growing defects, five causes of softening, sprain". Especially, atrophy is the most important symptom. Gait evaluation should be emphasized where a point can walk 8 feet to 10 feet considering stride width, stride length, the body weight center, stride number, flexion, extension, rotation of a joint as a standard factor. The point is we should find out something strange in a patient's side, front and back view. After that we should find out its cause as an index that we can observe abnormal findings in a joint and muscle.

Although the use of acupuncture for pain has increased in recent years, the mechanisms of acupuncture analgesia (AA) remains obscure. The lack of suitable experimental animal models for persistent pain, which show clear AA, has been the major stumbling block in the investigation of the physiological mechanisms of AA. In the present study, we test AA in two knee arthritis model induced by injection of CFA or carrageenan as a chronic pain model. After induction of arthritis, the rat subsequently showed a reduced stepping force of the affected limb for the next several days. Electroacupuncture (EA) was applied to an acupuncture point each on the contralateral forelimb for 30 minutes under enflurane anesthesia. After the termination of EA, behavioral tests measuring stepping force were periodically conducted during the next several hours. EA produced a significant improvement of stepping force of the foot lasting for at least 2 hours when applied to LR2 In CFA model, and applied to ST36 in carrageenan model, but both points did not produce any significant effects in each other model. These data suggest that EA produce analgesic effect in knee arthritic pain and the analgesic effect is specific to the acupuncture point.

Objectives : This study was designed to compare the effects on Korean Western Ontario and McMaster Universities Osteoarthritis Index(KWOMAC), 36-ltems Short-Form Health Survey(SF-36), Visual Analog Scale(VAS) and Nine Point Scale between 'Intramuscular Bee Venom Herbal Acupuncture' and 'Intracutaneous Bee Venom Herbal Acupuncture' in knee osteoarthritis patients for 4weeks. Methods : All the voluntary subject were diagnosed as knee osteoarthritis. Patients were randomly assigned either to two groups : Intramuscular bee venom herbal acupuncture treatment group(IM-BV group) or Intracutaneous bee venom herbal acupuncture treatment group(IC-BV group). The IM-BV group received bee venom herbal acupuncture intramuscularly on muscles closest to the pathologic site on ultrasonography. The IC-BV group received bee venom herbal acupuncture intracutaneously on $LE_{110}$, $LE_{201}$, $ST_{35}$, $ST_{36}$ and $LR_8$. Bee venom herbal acupuncture was applied twice a week for 4 weeks by an oriental medical doctor at Kyung-hee Oriental Medical Hospital. Both groups were checked of pathologic site by ultrasonography before treatment and follow up after four-week treatment. The patients were assessed by KWOMAC and SF-36 before and after four-week treatment. The changes in patients' pain was measured by VAS before treatment and after one-, two-, three- and four-week treatment. The patients' overall treatment outcome assesment was measured by Nine Point Scale after four-week treatment. Results : The results were as follows ; 1. The IM-BV group showed significant improvement on total, pain, stiffness and physical function in KWOMAC, and the IC-BV group showed significant improvement on total and physical function in KWOMAC after 4weeks compared to the pre-treatment. In KWOMAC, the IM-BV group showed more improvement on average compared to the IC-BV group, but there were no significant difference between two groups. 2. The IM-BV group showed significant improvement on VAS after one-week treatment. The IC-BV group showed significant improvement on VAS after two-week treatment. But there were no significant difference between two groups. 3. The IM-BV group showed significant improvement on physical functioning(PF) and bodily pain(BP) in SF-36, and the IC-BV group showed significant improvement on vitality(VT) and bodily pain(BP) in SF-36 after 4weeks compared to the pre-treatment. But there were no significant difference between two groups. 4. 88.2% of IM-BV group and 93.3% of IC-BV group graded their improvement as 'Fair' or better on Nine Point Scale. But there were no significant difference between two groups. Conclusions : This study suggests that in the treatment of knee osteoarthtitis patients, effects of 'Intramuscular Bee Venom Herbal Acupuncture' were not different from 'Intracutaneous Bee Venom Herbal Acupuncture' statistically. But both treatment showed effects on pain and physical function in knee osteoarthtitis patients.

Purpose : The purpose of this study was to analyze setter toss motion kinematically according to toss types. Method : Dependent variables were elapsed time, vertical displacement of the body center, the projected speed of the ball, and differences of the joint angle to the target for four setters positioning. Result : There was no significant difference in the time but the ball contact time was shorter when the toss distance of P3 was longer. There was significant difference in the vertical displacement of COM (p<.05). The vertical displacement of COM showed that the vertical movement gradually decreased when the quick distance was longer. The vertical displacement of COM was difference (p<.05), also there was difference of the ball speed (p<.001) at the Release point(E4). There was significant difference in the knee joint angle at a certain moment among the Release(E4) and Landing point(E5)(p<.05). The hip joint was significant difference among the Apex(E2), Ball Touch(E3), Release(E4), and the Landing point(E5) on the surface(E2, E3, E4 p<.05; E5 p<.005). The shoulder angle was significant difference among the Ball Touch(E3), Release(E4) and the Landing point(E5) on the surface(E3, E4 p<.05; E5 p<.001). The elbow was significant difference in the Apex(E2) (p<.05). The wrist was significant difference in the Release(E4) (p<.05). Conclusion : If we find the clue to expect the direction of the setter's ball, we have to fine the clues in the Apex(E2) that hip join and elbow, Ball Touch(E3) that hip joint and shoulder joint, Release(E4) that wrist, elbow, hip joint, and knee joint.

The PCL reconstruction in chronic isolate PCL reconstruction was still controversy. 1) In isolate PCL deficient knee, functionally not so bad as like ACL deficient knee. 2) The result of the PCL reconstruction was not as good as ACL reconstruction. Therefore, isolate PCL injuries has been treated as nonoperatively. Hey Grovere, who was the first to attempt an intra-articular reconstruction of the PCL, utilized the semi-tendinous tendon other static procedures have been described in only a few cases with very limited follow-up. Dynamic procedures utilizing the medial head of the gastrocnemius has been reported by Hugston and Degenhardt, Kennedy and Grainger, and Insall and Hood. These procedures did not improve static stability. Dr Clancy, who was introduce the use of BPTB for the PCL reconstruction transtibial and femoral tunnel. From 1995, untill early 1990 PCL reconstruction was done as tend as placement of the isometric point. Physiometic placement of Anatomical placement of the femoral tunnel in PCL reconstruction were introduced in 1995. Tibial Inlay Technique was reported by Dr Berg in 1995. The main advantage of the tibial Inlay Technique was to avoid fraying of the graft at the posterior tibial tunnel orifice. In complete PCL ruptured and severely posterior unstable knee, dual femoral tunnel technique will be to get better result than one bundle technique. To achieve restoration of normal posterior laxity, it is critical to address the posterior as well as the posterolateral structures. Futher research is necessary to evaluate new surgical approches such as double-bundle reconstructions and tibial inlay techniques as well as improved techniques for capsular and collateral ligament injuries.

Purpose:The purpose of this study was to examine the degree of joint pain, limitation of daily activities, and frequency of outpatient visits. Methods: This secondary analysis study used the data from the fifth Korean National Health and Nutrition Examination Survey (KNHNES). The data about general characteristics, prevalence and treatment of osteoarthritis, limitation of activities of daily living (ADL) and frequency of outpatient visits and hospitalization in 424 osteoarthritis patients over 50 years old were derived from the database. Data were analyzed with complex samples in SPSS ver. 20.0. Results: Among people with knee joint pain, 79.3% reported they had more than 4 out of 10 points of the degree of pain. Meanwhile, 97.3% of people with hip joint pain reported that they had more than 4 out of 10 points of the degree of pain. People reporting 10 out of 10 point of pain were 21.4% of those with knee joint pain and 25% of those with hip joint pain. The mean of the degree of knee joint pain was 6.35, and the mean of the degree of hip joint pain was 6.89 out of 10 points. About 50% of people with osteoarthritis visited an outpatient clinic within the last 2 weeks, and 27% had limitation of ADL. Conclusion: It is necessary to develop an integrated intervention program to improve quality of life in patients with osteoarthritis.

The purpose of this study was to analyze the biomechanical differences of lower extremity joints of the frontal plane during sidestep cutting in male and female Judo athletes. In the knee and hip joint, the female group showed a smaller angle than the male group at the time of IC(initial contact). But peak knee joint adduction moment of female group was greater than male group(p<.05). Therefore, female Judo athletes were more likely to injure their knees at the point where their initial foot contacted the ground than male athletes during sidestep cutting.
