Reconstruction of soft tissue defect of knee joint area has been remained a challenging task for plastic surgeons. The earlier the normal tissue saved and the necrotic tissue removed, the less the patients had complications and functional disability. But such defects are difficult to manage for its poor vascularity, rigid tissue distensibility, easy infectability and a relatively long healing period. The goal of flap coverage in the knee joint should not only be satisfactory wound coverage, but also acceptable appearance and minimal donor site morbidity. We have treated five cases using the anterolateral thigh perforator flaps for reconstruction successfully. In conclusion, we believe that in cases of knee joint area soft tissue defects, flaps like anterolateral thigh perforator flap should be considered as the first line of treatment.

Objectives : This study was done for reporting the effect of moxibustion therapy on Ryodoraku score of the patients with degenerative arthritis of knee joint. Methods : We investigated 65 cases of patients with degenerative arthritis of knee joint, and devided patients into two groups : One group treated by moxibustion therapy, which was not applied to the other group we analyzed of each group the Ryodoraku score(F1, F6) of each group before and after moxibustion therapy and compared it. Results : 1. In moxibustion therapy group compared with baseline, at final, Ryodoraku score(F1, F6) was significantly increased. 2. At final, moxibustion therapy group showed significant increase on Ryodoraku score(F1, F6) score compared with non moxibustion therapy group. Conclusions : It is suggested that Ryodoraku score(F1, F6) should be available for diagnosing degenerative arthritis of knee joint.

Walking training is one of the most important rehabilitation processes with paralysis patient. Walking training by using an orthosis can help advancing a patient's independent level. However, existing orthoses have some serious demerit of mechanical problem that the knee joint is locked in the state where it is completely extended, which increases energy consumption and fatigue. For this reason, it is suggested, for more practical orthosis, that the knee joint should be placed and it should have capability of suspending patient's weight. In this paper, 1-DOF walking orthosis which compensates the demerit of the existing orthosis and secures patient's mobility has been proposed. New orthosis has been designed under the following two premises. First, the knee joint of the orthosis was designed fold in order for the orthosis to move in a walking pattern similar to that of a normal person. Second, the knee joint was designed to extend during the swing phase and lock safely during the stance phase.

This study examined on the causes of chronic pain in the knee joint that was related to the aspects of teacher's job and daily lives. The subjects of investigation in this study include 237 of teachers who work at the elementary, middle and high schools. The chronic pain of knee joint of the subjects' is mainly related to their stress, and also to the vehicle that they normally use(p<0.05). This study aims at grasping the frequency of the pain which is caused by a knee joint's stress when teachers teach in a standing-up posture for many hours, looking at the aspects in the pain of knee joint that are related to job, being conducive to the development of the pain-cure, and, in addition, presenting an effective countermeasure to related agencies in order to prevent such diseases as arthritis.

Objectives : The objective of this study is to report the effect of Traditional Korean medical therapy and core exercise on osteoarthritis of knee joint by observing a clinical case study. Methods : Patient with a diagnosis of osteoarthritis of knee joint, was treated by acupuncture, herb medicine, physical theraphy and core exercise. Results : After treatment, Visual Analogue Scale(VAS), Korean version of the Western Ontario and McMaster Universities(KWOMAC), Pain Rating Score(PRS) were reduced from 5 to 2, from 25 to 16, from 55 to 27, and CENTAUR test results were improved. Conclusions : This study showed that Traditional Korean medical therapy and core exercise has meaningful effect on osteoarthritis of knee joint, and more researches should be followed.

Three dimensional joint motion data were obtained using precise magnetic sensors and X-ray. Six metal markers were inserted on the femur and the tibia to set the coordinate system. Two magnetic position sensors were used to record motion data and these positions were transformed into the knee motion. The quadriceps muscle was extended in an automatic manner by an extraction machine. Results of the knee motion were the same as the clinical data. The proposed method is found to be reasonable in describing the knee motion so that these motion data can be used to simulate the normal knee joint.

The aim of this study is to present the basic reference data of age and specipic gait parameters for comparisons of the gait characteristics depended on Unilateral Trans-Femoral or Trans-Tibial Prostheses. The basic gait parameters were extracted from 10 Adult, 10 above knee(A/K) patients and 10 below knee(B/K) patients, 50 to 60 years of age using VICON 512 Motion Analyzer. The results were as follows; 1) The mean Cadence of the above knee(A/K) patients and below knee(B/K) patients were $87.77{\pm}8.64$ steps/min, to $99.84{\pm}11.14$ steps/min.(p<0.05) 2) The mean Walking Speed of the above knee(A/K) patients and below knee(B/K) patients were $0.84{\pm}0.15$ m/s, to $0.96{\pm}0.25$ m/s.(p>0.05) 3) The mean Stride Length of the above knee(A/K) patients and below knee(B/K) patients were $1.14{\pm}0.14$ m, to $1.14{\pm}0.22$m.(p>0.05) 4) The mean maximal angles of joint on the hip flexion motion for different above knee(A/K) patients and below knee(B/K) patients were $34.75{\pm}10.18_{\circ}$, to $32.32{\pm}6.34_{\circ}$ .(p>0.05) 5) The mean maximal angles of joint on the knee flexion motion for different above knee(A/K) patients and below knee(B/K) patients were $66.97{\pm}15.08_{\circ}$, to $52.65{\pm}9.21_{\circ}$ .(p<0.05) 6) The mean maximal angles of joint on the ankle dorsiflexion motion for different above knee(A/K) patients and below knee(B/K) patients were $14.41{\pm}4.82_{\circ}$, to $10.04{\pm}3.49_{\circ}$ .(p>0.05) 7) The mean maximal angles of joint on the ankle plantarflexion motion for different above knee(A/K) patients and below knee(B/K) patients were $5.77{\pm}3.17_{\circ}$, to $2.75{\pm}4.49_{\circ}$ .(p>0.05)

Purpose:This study was designed to investigate difference in isokinetic muscle strength in the knee extensor muscle and characteristic differences in muscle strength between males and females through the ankle joint angles. Methods: Seventy-four subjects participated in this study. There were two groups: 36 males and 38 females. The mean age of the men was 24.58 years and women was 23.74 years. Subjects were seated on a CON-TREX LP (leg press) lean to back of chair, and there bodies were fixed by straps with the hip joint at an angle of $130^{\circ}$. After randomly fixing the ankle joint at $0^{\circ}$, $20^{\circ}$, and $40^{\circ}$ of plantar flexion (PF) in range of full extension of knee joint. We studied force max average, force max average/kg, power average, and total work through the angle of the ankle joint when the knee joint was extended from $90^{\circ}$ to $180^{\circ}$. Results: In the male group, all maximum measured value showed at the ankle joint $0^{\circ}$, all minimum measured value showed at $40^{\circ}$ PF (p<0.01). In the female group, all maximum measured value showed at the ankle joint $20^{\circ}$ PF, especially the power average increased significantly. All minimum measured value showed $40^{\circ}$ PF (p<0.01). Conclusion: There are differences between males and females in isokinetic muscle strength of the knee extensor through ankle joint angles in healthy adults. Males and Females have different characteristics of muscle strength through the ankle joint angles.

This study was carried out to characterized the effect of Youndamsagan-tang on a Case of Septic Knee. After we gave Youndamsagan-tang to a patient of septic knee, we examined not only symptom of patient but also the thickness and circumference of knee, the change of WBC, ESR, body temperature, VAS. As admission time passes, the pain, flare, swelling and movement of left-side knee joint were improved. The thickness and circumference of knee joint were decreased, and the count of WBC, ESR were decreased. And patient's pain by VAS was subsided. From the above result, administration of Youndamsagan-tang reduces the progressing of pain, flare, swelling and movement in knee joint.
