In the case of Posterior Cruciate Ligament (PCL), the most frequent mechanism is the dashboard injury, which is directly pressurized to the anterior of the proximal tibia in the state of the knee hyperflexion. The PCL associated ligament damage happens when the posterior injury, the varus, the valgus, the hyperextension and the severe vagus torque are out of the critical value of PCL. After the successful operation cases of Anterior Cruciate Ligament (ACL) reconstruction using the allograft were informed from 1986, a number of results kept over the maximum 10 years were reported. Unfortunately, PCL reconstruction are crowded the surgery techniques such as the graft, the tibia fixing method, the fixation device, the location of the femoral tunnel, the number of the graft bundles and PCL reconstruction to access to the stability of the normal joint is being developed. Therefore, this study is the basic research of these above facts. The current transtibial tunnel surgery using the cadaveric Achilles tendon grafts is chosen for the various PCL reconstruction. The initial extension of the Achilles tendon by the fixing device and its location under the cyclic loading, were observed.

전방십자인대 재건술에 있어서 최근 가장 각광받고 있는 개념은 해부학적 전방십자인대 재건술이다. 경경골 술식을 이용한 고전적인 방법에 비하여 해부학적 재건술을 위해서 경골터널은 이전보다 전방으로 이동하며 대퇴터널은 낮고 비스듬한 방향으로 만들게 된다. 따라서 낮고 비스듬한 해부학적인 위치의 대퇴터널을 만들기 위하여 전내측 도달법을 통한 술식(anteromedial portal technique), outside-in 술식, 그리고 변형된 경경골 술식(modified transtibial technique) 등이 시행되고 있다. 각각의 방법은 장단점이 있어 술자의 선호도, 경험, 사용 가능한 기구 및 이식건의 선택 등에 따라 선택된다.

자가 슬괵건을 이용한 전방 십자인대의 재건술시 사용되는 Poly-L-Lactic-Acid 성분의 생분해성 간섭나사로 인한 합병증은 많지 않다. 저자들은 전방 십자 인대 재건술시 생분해성 간섭나사로 이식건을 고정 후 경골 터널 전방에 발생한 결절종에 대해 결절종 절제술과 동시에 간섭나사를 제거한1예에 대해 보고하는 바이다.

In the present paper the current clinical knowledge about proprioception is given for the shoulder, knee, ankle, elbow and the radiocarpal joint. Proprioceptive capabilities are decreased after knee joint injury such as anterior cruciate ligament. Joint position sense is significantly improved by cruciate reconstruction. Thus, we review of the articles for the proprioception of the anterior cruciate ligament of the knee joint. The present information on proprioception will influence our clinical practice in the future. We should choose surgical procedures that not only reconstruct the anatomy, but also the neurophysiologic feed-back mechanism.

The isometric position of the anterior cruciate ligament was calculated during flexion-extension. Flexion-extension motion data of the knee joint were obtained by Fastrak, a three-dimensional motion measurement system. A subject was seated on a flat table and the tibia sensor position was measured with the femur fixed at the table. A three-dimensional knee model was constructed using a graphic tool to simulate the knee motion. Three surgical positions of the femoral tunnel were selected and the distances between the determined tibial tunnel and each femoral tunnel were calculated. The maximum elongation position was found to be in the ten thirty direction of clock.

목적 : 동종 이식건을 이용하여 전방 십자 인대 재건술을 시행한 후 추시하여 임상 결과 및 방사선학적 변화를 관찰하고자 하였다. 대상 및 방법 : 1995년 1월부터 1998년 12월까지 동종 이식건을 이용하여 관절경적 전방 십자 인대 재건술을 시행한 환자 중에서 1년이상 추시가 가능한 22례를 대상으로 전방 전위 검사, Lachman 검사, Pivot shift 검사, 방사선 촬영, 건측과 환측의 슬관절 운동 범위의 차이 및 CA-4000 knee motion analyzer를 이용하여 양측 슬관절의 전위 정도를 측정하였고, Lysholm knee score 를 이용하여 평가하였다. 결과 : Lysholm knee score는 술전 평균 54점에서 술후 평균 81점으로 평균 27점 증가하였고, CA-4000 knee motion analyzer를 이용하여 전방 전위력을 가하여 정상측과 비교한 양측 차이가 3 mm 미만인 경우가 16례$(73\%)$, 3 - 5 mm인 경우가 4례$(18\%)$, 6 mm 이상인 경우가 2례 $(9\%)$였다. 12례에서 평균 1.5 mm의 경골 터널 크기의 증가를 보였지만, 골융해나 낭종 형성의 소견은 없었고 터널 크기의 증가와 임상 결과와는 무관하였다. 결론 : 제한적 증례이지만 동종 이식건을 이용한 전방 십자 인대 재건술의 임상적 결과는 문헌에서 보고된 자가 이식건을 이용한 경우에서의 임상적 결과와 비슷한 양상을 보였고, 이 같은 결과로 미루어보아 전방 십자 인대 재건술시 동종 이식건은 훌륭한 자가 이식건의 대체물이 될 수 있다고 사료된다.

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 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.

Purpose: The purpose of this study was to identify changes in knee muscle strength after reconstruction of the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL). Methods: Thirteen subjects (males) with anterior ligament injury and ten subjects (males) with posterior ligament injury voluntarily participated in this study. Both groups were evaluated at the pre-and post-reconstruction stages using an isokinetic dynamometer. Peak torque, total work, and the hamstrings to quadriceps (H/Q) peak torque ratio were calculated at angular velocities of 60°/sec and 180°/sec. Statistical analysis was conducted on SPSS 18.0 for Windows using t-tests to compare mean differences. Results: At an angular velocity of 60°/sec, both the ACL and PCL groups showed a significant increase in muscle strength in the flexors and extensors. Muscle strength in the extensors was significantly increased in the PCL group compared to the ACL group. At an angular velocity of 180°/sec, the ACL group showed a significant increase in muscle endurance in the flexors and extensors, and the PCL group showed a significant increase in muscle endurance in the flexors. At angular velocities of 60°/sec and 180°/sec, the H/Q peak torque ratio increased in the ACL group but decreased in the PCL group. Consequently, the H/Q peak torque ratio was significantly different for the two groups. Conclusion: The results suggest that the patients with ACL injury should focus on strengthening the knee extensors and that the patients with PCL injury need to strengthen the knee flexors.
