Purpose : Genu varum is a condition characterized by a wider than normal gap between. This may be due to muscle weakness caused by poor posture, lifestyle, or lack of exercise. This study aimed to compare the effects of ball-based squats and narrow squats on muscle thickness, Q-angle, and the gap between the knees, in order to assess the potential for improving this condition. Methods : Twenty six adult participants with genu varum were randomly assigned to either a ball-based squat group (n=13) or a narrow squats group (n=13). Both groups performed their respective exercises three times weekly for 4 weeks. The data was analyzed using paired t-tests to compare pre- and post- intervention measurements within each group, and independent t-test was used to compare the two groups. Results : Both groups showed significant improvement in the thickness of the vastus lateralis and medialis, and rectus femoris muscles, as well as a significant decrease in the gap between the knees (p<.05). However, there was no significant difference in Q-angle variation between the two group. Furthermore, there was no significant differences in the Q-angle, gap between the knees, and muscle thickness variation between both groups. Conclusion : The results suggest that both ball-based squats and narrow squats are effective in improving muscle thickness and reducing the gap between the knees in adults with genu varum. However, there was no significant difference between the two types of squats in terms of their effects on the Q-angle. These findings highlight the potential for exercise interventions to address this common postural issue.

This study categorized 100 female subjects over 65 years of age into two groups. The first group is called 'early stage of varus', which is when the gap between the knees is less than 5 cm. The second group is called 'progressive varus', which is when the gap between knees is 5 cm (or more). We then analyzed their lower body shapes and life status. The results were as follows. The average gap between knees in the early stage group and the progressive group was 3.3 cm and 6.2 cm. Direct and indirect measurements of their lower bodies showed that subjects in the progressive group had longer legs than the other group because their legs were bent outwards. Most of the subjects were found to live in western housing conditions, but maintained sedentary lifestyles. A total of 60% of the subjects thought that they were in bad health conditions and said that they found it difficult to move their knees dynamically; in addition, 63.6% of the subjects in the early stage group and 73.5% of the subjects in the progressive group suffered from arthritis. Subjects in the progressive group were more aware than the other group that their legs were bent outwards. They also responded that bent legs do harm to their appearance and make their lives uncomfortable. Most senior females with varus did not seek medical treatment and did not buy clothes that can help change their varus. However, 95% of the subjects responded they were in need for clothes that could straighten the varus-type.

Purpose : The purpose of this study is to investigate the effect of squat exercise using a ball on the gap between knees and Q angle of a subject with a genu-varum, and to prove the effect, to provide a clinical basis for developing into a knee correction exercise program. Methods : As a result of posture measurement through GPS, 26 female with genu-varum with a knee length of 5 cm or more were studied. The group was randomly assigned to 13 squat exercise group using ball (experimental group) and 13 general squat exercise groups (control group). The experimental group placed the ball between both knees in a position where the distance between both feet was slightly wider than the shoulder width on a flat support surface, and fixed the ball, and then squat with the start signal. The control group squats without a ball. Each group performed three sets of exercise three times a week for six weeks. Before their exercise, after three and six weeks, EMG, GPS, digital goniometer measurement, the vastus medialis (VM), the vastus lateralis (VL), and the Q-angle were measured in the squat exercise posture. EMG was measured in squat exercise posture. Results : The distance between the knees was reduced. EMG is activated in group A, the group B experimental results showed the high activity of the VL. Q-angle had increased. But the experimental group increased more than the control group. Conclusion : We have confirmed through our experiments that the distance interval between the knees during squat exercises using a ball can be reduced. Furthermore, it would also be helpful to ensure the treatment of genu-varum.

Purpose: To evaluate the relationship between the knee function at 1 year postoperation and the gap difference (90° flexion gap-extension gap) in total knee replacement. Materials and Methods: Eighty-two consecutive osteoarthritis knees that underwent primary total knee replacement using navigation from March 2017 June 2017 were evaluated prospectively. The gap was measured using navigation after reducing the patella with towel clips. After checking the average values of the medial and lateral gaps at extension and 90° flexion knee, the gap difference (90° flexion gap-extension gap) was calculated. The knees were divided into three groups according to the gap difference (gap difference<0 mm, 0 mm≤gap difference<2 mm, 2 mm≤gap difference). The Knee Society score (KSS) and maximal knee flexion were compared at 1 year postoperation among three groups. Results: The numbers of knees according to groups were 37, 29, and 16 knees in regular order. The average of the KSS knee, KSS function, and maximal knee flexion at the 1-year follow-up were 81.21±8.31, 71.34±9.84, and 126.48°±7.28°, respectively. No statistically significant difference in KSS was observed among the 3 groups. The third group (2 mm≤gap difference) showed a larger maximal knee flexion than the other groups in the Mann-Whitney test. Conclusion: The group of total knee replacement (2 mm≤90° flexion gap-extension gap) showed larger maximal knee flexion than the other groups at the 1-year follow-up in statistics.

This study is aimed to evaluate the effects of the educational program that is designed to help the patients of T.K.R.A. to improve their self-nursing ability. The research will show how well this program can contribute to raising of their adaptability of everyday life by decreasing the difficulties that the patients had before in their daily life. The sample persons for this research were 40 adult patients who had T.K.R.A. in our hospital, and the data were collected through the questionnaires which were given to them. For the surveying tool, Jette's scale was applied to measure the degree of uncomforting that the patients experienced in their daily life. The materials of report had been gathered from May 1st to December 10th. The collected data were analyzed with real numbers, percentage, average, the standard deviation, TorF test and Pearsons correlation. The results of this study can be summarized like follows: The survey of self-caring exercise part were processed with two groups containing experiment group and contrast group. The exercise which took the highest points in experiment group was repetition of stretching and bending knees with laid down position while taking a walk, repetition of stretching and bending knees with seated on chair position and repetition of stretching and bending knees with laid down position got high points in contrast group. There were distinctive differences in statistics between repetition of stretching and bending knees in laid down position and taking a walk. There was no significant statistical gap between the degrees of inconveniences of daily life that each two groups experienced when we compared the average of the two groups, but 12 out of 20 questions got considerable differences. According to common characters of self-caring, there was a distinctive gap in the group who left the hospital in 14days and the ones who spend more than 30 minutes with exercise. The patient group who left the hospital in fourteen days after T.K.R.A. spent more time doing self-caring exercise. In the relationship between common characters and the degree of difficulties of daily life, Exercising is effective and Spending more that 30 minutes for exercise showed visible differences. The patients who answered that exercise are effective and put more time for it experienced less pain in their everyday life. The data proved by Pearson's correlation showed the relationship between self- caring and the degree of pain of daily life. According to the result, the increasing of self-caring activities helped to down the degree of inconveniences of daily life. This data show that T.K.R.A. reduced self-caring exercise ability and daily life activities. Therefore, the medical staffs who would take care the T.K.R.A. patients should offer stable nursing through well scheduled and education materials for patients. It is also important to encourage the patients to participate to the exercise by showing them how exercise after T.K.R.A. The education program is expecting to guarantee not only the right of patients to get enough information but also effective result to decrease uncomfortable of daily life.

This study aims to rectify the disfigurement of bowlegged, (which means they have a gap between knees due to knee joint problems) females in their twenties through the development of pants patterns. The contents of the study are as follows: First, two types of basic pattern-making methods were selected. Two mock-ups, which were made by using these pre-selected basic patterns, were worn by three bowlegged participants and evaluated with a fit test. A basic pattern, which had good body fit was selected, which had a bubble or a wedge at in crotch area and roomy or snug upper thigh. Second, the mock-up, which was made by using the selected basic pattern, led to the outward movement of crease lines. Two types of patterns that were adjusted were evaluated through a fit test. As a result, an effective adjustment for moving the crease line to the outside or to the center was to cut along the slash line of a horizontal balance line to, but not through the crotch seam to spread the pattern at the hip. Third, three patterns were readjusted using the chosen alteration pattern, and the crotch seam and spread patterns of 1 cm, 2 cm, and 3 cm at the hip were applied. As a result of the evaluation of the fit test, three participants-the majority-showed a better fit when the spread amount in the pattern was 2 cm, although every participant did have a different gap between the knees. This study has significance in which rectifies the disfigurement of bowlegged individuals through the development of patterns for females in their twenties who are bowlegged.

Most knee axial radiographs, known as sunrise and skyline view, were performed with the patient in the prone position. The authors tried to address some of the shortcomings of conventional radiography by developing a new radiography method, K-RAD. According to previous research, the K-RAD method showed a wider patellar-femoral joint space than conventional radiography and provided a clear patellar hemi-lateral image with a constant gap between the femoral trochlear groove and tibial tuberosity. The authors worked with an orthopedic specialist to perform radiography using the K-RAD method rather than using existing methods, and as a result, the two knees were aligned correctly and a clear image of the patellar-femoral joint space was created. The authors propose the K-RAD method for knee axial radiography because the K-RAD method provides a sense of stability to the patient and provides images with high diagnostic value.
