Purpose: This study examined the effects of squatting with different foot positions on the muscle activation of the vastus medialis oblique (VMO) and vastus lateralis (VL) muscles in subjects with genu varum. Methods: Thirty four subjects participated in this study. Surface electromyography was used to measure the muscle activation of the VMO and VL muscles at the knee angles ($15^{\circ}$, $60^{\circ}$) at three foot positions (internal rotation, neutral position, external rotation) during squatting. Results: Muscle activation differences at different knee angles and foot positions differed significantly between the VMO and VL muscles in both the varus and normal groups. In addition, there was a significant difference according to the knee angles with the foot in external rotation in the VMO and VL ratio. In the varus group, however, the VMO and VL ratio were significantly different only with the feet in internal rotation. In the muscle activation changes of the knee angle differences in the foot position, there was no significant difference in the varus group, but both the VMO and VL muscles were significant different in the normal group. Conclusion: In both groups, regardless of the foot position, muscle activation of the VMO and VL muscles increased with increasing knee flexion angle. In the normal group, when squatting with the feet in external rotation, the VMO and VL muscles activations increased with increasing knee angle. In the varus group, however, the foot position did not affect the VMO or VL muscle activation. This study shows that subjects with genu varum and normal subjects have different VMO and VL muscle activation patterns during squat exercises.

In general, the operative treatment of the brachymetatarsia is the lengthening of the affected metatarsal bone due to the cosmetic problem rather than the functional one. We experienced 22 year-old female bilateral congenital foot deformities such as hallux varus and 1,4th brachymetatarsia treated with reverse Scarf osteotomy on the hallux varus and massive axial metatarsal shortening Weil osteotomy on the 2,3,5th metatarsals which could reconstruct the normal metatarsal parabola.

육상 선수나 격투기 선수들에게서 전족부 손상은 흔한 편이나 족무지 지간 관절은 해부학적 안정성으로 인해 관절 측부 인대손상은 매우 드문 것으로 알려져 있다. 특히 스포츠 손상에 의한 지간 관절의 만성 불안정성에 대해서는 국내외적으로 보고가 극히 적어 저자들은 대학 태권도 선수에서 족무지 지간 관절의 진구성 외측부 인대 파열에 기인한 만성 무지 내반 불안정성에 대하여 수술적으로 치료하여 좋은 결과를 얻었기에 이를 보고하고자 한다.

The purpose are to demonstrate the pain, stiffness, and physical function by the Korean Western Ontario MacMaster University(KWOMAC) score of the patients with varus deformity osteoarthritis of the knee after treatment period. Twenty outpatients with knee osteoarthritis(OA) were randomized and divided into the control(n=10) and wedge(n=10) groups. The remission scores of the KWOMAC index of severity for knee OA were compared between the groups. The result of repeated two-way ANOVA's revealed that a contact lateral-wedged insole with strapping produced significantly differences in the pain and physical function score between groups after treatment period(P<0.05), but it was not significant differences in the stiffness score between groups(P>0.05). These results suggest that the pain relief and improvement in function reported by patients with osteoarthritis while using lateral-wedged insole with strapping may be achieved by a reduction in external varus moment and medial compartment load.

The purpose of this study was to report the reliability and validity of oblique single-cut rotation osteotomy (OSCRO) in 3D-reconstructed canine bone models with femoral varus and torsional deformities. A healthy adult male beagle was recruited to create a 3D bone model, and this bone model was modified by using a 3D program. Fifteen bone models were constructed for this study. OSCRO simulation was performed in accordance with the plan after printing using a 3D printing machine. The anatomical lateral distal femoral angle (aLDFA), anteversion angle (AA), anatomical caudo-distal femoral angle (aCdDFA), mechanical caudo-distal femoral angle (mCdDFA) and pre- and postoperative bone length were calculated. There were no significant differences between the target values and postoperative values. In addition, the difference between pre- and postoperative bone length was small (p = 0.001). Our findings suggest that OSCRO could be an effective surgical option for MPL with bone deformities in small-breed dogs that often undergo conventional distal femoral osteotomy.

A 74-year-old female patient, who underwent surgery for a left distal tibiofibular fracture 40 years earlier, visited the hospital with an ankle varus deformity due to malunion. The patient complained of discomfort while walking due to the ankle and hindfoot varus deformity but did not complain of ankle pain. Therefore, correction using supramalleolar osteotomy was planned, and through virtual surgical simulation, it was predicted that a correction angle of 24° and an osteotomy gap open of 12 mm would be necessary. An osteotomy guide and an osteotomy gap block were made using three-dimensional (3D) printing to perform the osteotomy and correct the deformity according to the predicted goal. One year after surgery, it was observed that the ankle varus was corrected according to the surgical simulation, and the patient was able to walk comfortably. Thus, for correction of deformity, virtual surgical simulation and a 3D-printed osteotomy guide can be used to predict the target value for correction. This is useful for increasing the accuracy of correction of the deformity.

본 연구에서는 디지털 텔로메터를 이용하여 20 대 정상 남자와 여자 무릎 외측측부인대의 안정성에 대한 평가를 시행하고자 하였다. 지원대상자는 본 연구 목적에 동의하고 과거 무릎 관련 질병이 없는 정상 성인 31 명(남자 16 명, $21.1{\pm}1.5$ 세, 여자 15 명, $21.2{\pm}1.2$ 세)을 대상으로 하였다. 실험방법은 디지털 텔로메터를 이용하여 내측대퇴경골관절강에 내반력의 힘을 가한 후 압통정도를 조사하였고 디지털 방사선영상에서 외측 무릎관절공간(JSW)을 측정하였다. 그 결과 무릎에 부하의 힘을 가하지 않은 상태에서의 남자그룹의 JSW는 $5.60{\pm}0.76$ mm, 여자그룹의 JSW는 $5.05{\pm}0.55$ mm로 유의한 차이를 보였다(p=0.022). 그러나 무릎에 부하의 힘을 가한 결과, 여자그룹이 남자그룹보다는 다소 더 넓었지만 통계학적으로 유의한 차이가 없다(p>0.05). 무릎에 부하의 힘을 가할 때 남녀 모두 약 17~19 daN에서 압통을 느꼈다. 이 결과는 향후 디지털 텔로메터를 이용한 무릎 관절 외측측부인대의 안정성 검사 시 유용할 것으로 사료된다.

The purposes of this study were to describe and compare pint moments according to 6 types of gait methods during free speed. 15 volunteers(7 male, 8 female: mean age = 23.33 yrs.) participated and performed 6 types of gait methods. From the 3 types of pint moments of lower extremities(hip, knee, ankle and foot), the following results were made: 1. In left hip pint, the flexion-extension moment was not significantly different, but the adduction-abduction moment and rotation moment were showed different curves during stance phase. 2. In left knee pint, the flexion-extension moment was not significantly different, but the varus-valgus moment and rotation moment were showed different curves during stance phase. 3. In left ankle and foot the dorsiflexion-plantarflexion moment was not significantly different but the varus-valgus moment and rotation moment were showed different curves during stance phase. In conclusion, because weight loading gait with 10-20% of body weight were normal gait patterns, It was inferred that all weight loading gaits did not indicate noxious reactions of human body.

Low tibial osteotomy is an extra-articular procedure that realigns the mechanical axis, restoring ankle function. It is also an alternative surgical procedure to manage early osteoarthritis of the ankle joint. This can mainly address ankle varus/valgus, as well as procurvatum/ recurvatum, internal/external rotation, equinus, calcaneus, and limb length discrepancy. The authors describe the history, mechanism, indications, and limitations of low tibial osteotomy focused on osteoarthritis of the ankle with varus malalignment reviewing several articles published thus far.
