Purpose: This study was to determine the effects of before and after application of silicone sleeve on balance and muscle strength in anterior cruciate ligament (ACL) reconstruction patients. Methods: 13 subjects who had one or more months after ACL surgery were involved. Dynamic balance, timed up and go (TUG), stair step, vertical jump, proprioception and isokinetic knee strength were measured while subjects under taped, untapped and silicone sleeve conditions. Results: For 30 seconds one-leg standing, there was a significant improvement under silicone sleeve on operated side with eyes open and both taping and silicone sleeve revealed similar effects with eyes closed (p<0.01). Application of silicone sleeve showed significant effects in proprioceptive function on the operated side compared to both taping and none (p<0.05). For stair step test, TUG and vertical jump was a tendency to improve after application of silicone sleeve, but no significant different. Muscle strength on operated side of quadriceps and hamstring was significantly improved compared with none or taping(p<0.05). Conclusion: Silicone sleeve application for ACL reconstruction patients was effective immediately on improving strength and balance. Therefore, depending on the intended use and the disease is considered appropriate use of silicone sleeve will be able to help prevention and functional movement.

Purpose : This study was to comparison of EMG of an stable exercise group and unstable exercise group on patients who have had anterior cruciate ligament reconstruction(ACL reconstruction). Methods : The subjects of the study were patients who had no less than 4 weeks after ACL reconstruction and could stand on one leg, and they divided into a control group with 9 patients doing closed kinetic chain exercises on the stable floor and an experimental group with 10 patients doing closed kinetic chain exercises on the unstable floor and in order to compare degrees of the muscle activity of the thigh extensor and flexor was tested each before the exercise, in 3 weeks and 6 weeks after doing exercises by using surface electromyography (Surface EMG). The patients made 3 sets of exercises (10 times per set), each of which consisted of exercises using elastic bands and the squat. Results : There was statistic significance about the vastus medialis muscle. Conclusion : It is thought that the closed-chain exercise could be an exercise program through which patients could enhance the muscle activity of the vastus medialis muscle optionally among the quadriceps muscle and the hamstring muscles which should weaken after ACL reconstruction.

전방십자인대 손상은 모든 연령 대에서 고위험 운동에 참여하는 인구의 증가로 계속 증가하고 있다. 골-슬개건-골을 이용한 전방십자인대 재건술이 가장 많이 시행되는 수술이다. 지금까지 골-슬개건-골 자가이식물이 가장 이상적인 전방십자인대 재건술의 이식물이라고 하는 주장을 바꿀 만 한 충분한 자료가 아직 없다. 골-슬개건-골 이식물의 생체역학적 특징, 공여부 이환과 적응증을 고찰하고, 이를 이용한 내시경적 전방십자인대 재건술의 수술 수기를 기술하고자 한다.

Anterior cruciate ligament(ACL) of human body experiences a large deformation. May during everyday when large deformation is repeated by various activities such as outdoor activity, ACL easily get damaged. In order to acknowledge the effect of the cyclic large deformation to ACL, the constitutive equations for ACL are derived from experiment data. The concept of the objective stress rate plays a important role wherever large deformation occurs. In order to obtain the objective stress rates the eigenprojection technique is used. A comparison is made for four different cases: Jaumann rate, Green-Naghdi rate, logarithmic rate and twirl tensor of Eulerian triad rate for an isotropic material subject to cyclic deformation, such as simple shear motion. Four different materials are studied to compare the behavior of the materials for ACL using different objective rates. Finally, more complicated model with fibers for soft tissues is used to calculate the behavior subjected to cyclic large deformation.

Congenital deficiency of the anterior cruciate ligament (ACL) is a rare disorder that has been reported in association with other knee dysplasia like as congenital knee dislocation. congenital short femur, congenital absence of menisci, congenital ring meniscus, and thrombocytopenia-absent radius syndrome. There has been no published explanation about the etiology of bilaeral ACL deficiencies without other abnomality. The patient of congenital ACL deficiency must be carefully inspected about combined anomaly. Those efforts may be helful in treatment or ACL deficient patients and evaluation of pathophysiology or ACL deficiency. However there has not been a ruptured congenital deficiency of the ACL without other dysplasia or the knee and other congenital skeletal abnomalities. We reported a case of symptomatic bilateral congenital deficiencies of the ACL which have not been associated with other skeletal abnormalities.

Background: The purpose of this study was to identify the comparison of the muscle contractile properties on lower extremity between non-injury and injury in subjects with anterior cruciate ligament reconstruction (ACLR). Methods: Twenty-four subjects on the post-operative ACLR participated in this study. Measurement method were using tensiomygraphy to analyze the displacement maximum(Dm) and contraction time(Tc) on the both quadriceps. Results: Compared difference of the Dm between non-injury and injury, the rectus femoris (RF) and vastus lateralis (VL) increased significantly (p<.01). However, vastus medialis (VM) no significantly difference between non-injury and injury. Compared difference of the Tc between non-injury and injury, the RF increased significantly (p<.01) but VL and VM no significantly difference between non-injury and injury. Conclusions: These findings suggest that occurred muscle atrophy of the RF and VL and change properties of muscle fibers on the RF from fast muscle fibers to slow muscle fibers on the injury side of post-operative ACLR. Therefore, when apply to rehabilitation of lower extremity for post-operative ACLR, we should consider the enhance of RF and VL on injury side.

전방십자인대 재건술의 최신 지견과 관련된 전반적인 내용, 즉 해부학, 생역학, 수술 방법 및 임상 결과를 문헌 고찰하였다. 전방십자인대 재건술에는 다양한 술기가 있으며 현재 널리 쓰이고 있는 방법으로는 단일 다발 재건술, 인대 잔유물 보존-보강술, 이중 다발 재건술 등이 있다. 이 중 어느 방법이 우월하다는 보고는 없으며, 각 술기의 장단점이 보고되고 있다. 따라서, 모든 환자에서 동일한 수술 방법을 선택하는 것보다는 환자 개개인의 특성, 손상의 정도 및 잔유 인대의 상태 등에 따라 재건술의 방법을 선택하는 것이 바람직할 것으로 생각된다.

내측 반월상 연골에 생기는 기형은 매우 드물고 임상적으로 진단하기 어렵다. 이러한 기형 중에서도 전방십자인대에 이상 부착을 보이는 내측 반월상 연골은 드물다. 대부분의 보고된 증례들은 임상적인 증상과 연관을 보이지 않으며 관절경검사를 하면서 우연히 발견된다. 우리는 드문 증례인 전방십자인대에 이상 부착을 보이는 내측 반월상 연골에 대한 자기공명 영상을 보고하고 문헌을 통한 간략한 검토를 하려고 한다.

The purpose of this study was to investigate the effects of landing tasks on the anterior cruciate ligament (ACL) injury risk factors in female basketball players. Fifteen female basketball players performed a drop landing and a drop landing with a vertical jump on the 40 cm height box. Three-dimensional motion analysis system and ground reaction force system was used for calculate the ACL injury risk factors. Paired samples t-test with Bonfferoni correction were performed. The drop landing with a vertical jump had the higher knee flexion angle, peak knee varus moment, trunk flexion angle than a drop landing. However, the drop landing had the higher trunk rotation angle than a drop landing with a vertical jump. These results indicate that seemingly minor variations between drop landing and drop landing with a vertical jump may influence the ACL injury risk factors. Caution should be used when comparing studies using different landing tasks.
