The natural history of the anterior cruciate ligament(ACL)-deficient knee remains controversial. although numerous investigation have tried to ascertain the course that the knee would follow once the ACL has lost functional integrity. An extensive review of the literature performed according to symptoms. physical examinations, associated surrounding tissue injuries. returns to activity level and radiological changes in the knee joint. An active individual with a non-functioning ACL was susceptible to injury to the menisci and deteriorate the articular cartilage, followed radiographic changes. An activity levels in general also changed after injury. The most common symptom was pain. But instability varied in these individuals. Conclusively we believe that all these factors will eventually, if not initially, result in a symptomatic knee. which will result in significant limitations to the individual's desired level. So we recommend an aggressive approach in person who desired to return to a relatively active life style in young person as well as in middle aged individuals who have significant symptomatic ACL deficient knee.

Purpose: Tunnel widening following anterior cruciate ligament (ACL) reconstruction is commonly observed. Graft micromotion is an important contributing factor. Unlike fixed-loop devices that require a turning space, adjustable-loop devices fit the graft snugly in the tunnel. The purpose of this study is to compare tunnel widening between these devices. Our hypothesis is that the adjustable-loop device will create lesser tunnel widening. Materials and Methods: Ninety-eight patients underwent ACL reconstruction from January 2013 to December 2014. An adjustable-loop device was used in 54 patients (group 1) and a fixed-loop device was used in 44 patients (group 2). Maximum tunnel widening at 1 year was measured by the L'Insalata's method. Functional outcome was measured at 2-year follow-up. Results: The mean widening was 4.37 mm (standard deviation [SD], 2.01) in group 1 and 4.09 mm (SD, 1.98) in group 2 (p=0.511). The average International Knee Documentation Committee score was 78.40 (SD, 9.99) in group 1 and 77.11 (SD, 12.31) in group 2 (p=0.563). The average Tegner-Lysholm score was 87.25 (SD, 3.97) in group 1 and 87.29 in group 2 (SD, 4.36) (p=0.987). There was no significant difference in tunnel widening and functional outcome between the groups. Conclusions: The adjustable-loop device did not decrease the amount of tunnel widening when compared to the fixed-loop device. There was no significant difference in outcome between the two fixation devices. Level of Evidence: Level 3, Retrospective Cohort.

심부 정맥 혈전증(deep vein thrombosis)과 폐색전증(pulmonary embolism)은 정형외과적 수술 후 발생할 수 있는 심각하고 치명적인 합병증이다. 대부분의 시술은 인공관절 치환술등 절개가 큰 시술 후에 발생한다. 반면 슬관절의 관절경적 시술 같은 최소 침습적 수술의 경우, 그 위험도 및 예방적 조치에 대해 명확하게 밝혀지지 않고 있다. 슬관절의 관절경적 시술 후 발생한 폐색전증의 국외보고는 다소 있으나 국내보고는 아직 없어 2례에 대하여 보고하고자 한다.

Purpose. To investigate the effects of a video education program on anxiety, pain, adherence to self care of knee arthroscopy surgery. Methods. The data were collected from July to October 2012. The participants were 25 people in the experimental group and 25 in the control group. The video education, which was 30 minutes in length, was shown before operation day using a CD. Results. In the experimental group, adherence to self care increased significantly, and anxiety, VAS is not significantly compared to the control group. Conclusions. It has been confirmed that video education program has positive effects on adherence to self care for patients following arthroscopy surgery.

As computer technology develops and this is applied to medical image field, three dimensional image reconstruction technology using computer simulation is utilized in various categories that include anatomical study and biomechanics study of human body. Especially orthopedic surgeons are able to investigate biomechanical function and be provided information for operations with this technology in terms of ligament reconstruction of knee. And this technology can be utilized in preparing preoperative planning and instructions and training. This review is about three dimensional image reconstruction technology which is utilized in ligament reconstruction of knee.

The use of autogenous tissues is preferred for knee ligament reconstruction. However allografts play a role in major ligament reconstructive procedures in which multiple substitutions or revisions are required. In the dislocated knee, allografts may offer an advantage in reconstructing the PCL. But allografts in knee ligament surgery must be considered in terms of biomechanical and regenerative properties, disease transmission and immunogenecity, and methods of preservation and sterilization. Also only a few authors have described the use of allograft for reconstruction of a ruptured PCL, either a single procedure, or in combination with ACL repair following knee dislocation. Furthermore, the problems that the clinician faces with use of allografts is the necessity for supervision to ensure that the grafts are correctly processed, secondarily sterilized, and free of transmissible diseases. For these reasons, the routine use of allograft materials in the treatment of ligament deficiencies should be avoid and provide with meaningful outcome studies, including longterm follow-up.

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 anterior cruciate ligament(ACL) is, perhaps, the most intriguing component of the knee joint. Initially referred to crucial ligament because of the cruciate or crossed arrangement or the anterior and posterior ligaments within the knee. the irony or the ACL being crucial to the well-being or the joint has only recently appreciated. The anterior cruciate ligament of human knee joint is a complex structure and its orientation, construct and biology arc directly related to the knee function as a constraint of knee joint motion. In addition to its functional role as a static stabilizer or the knee. the ACL has a unique neurovascular system. The vascular anatomy of the ACL plays a crucial role in the repair and reconstruction of the ligament, and the neuroreceptors found in its substance suggest a possible proprioceptive role for the ligament. The structural complexity of the ACL allows the ligament to function through the normal range of motion as a static stabilizer or the knee. hut it also makes the exact duplication of this structure very difficult. A comprehensive knowledge or the anatomy of the ACL can provide the orthopedic surgeon with a blueprint for the idealized repair and reconstruction of this most complex structure.

외상성 슬관절 탈구 중 도수 정복되지 않는 경우는 매우 드물며 대개는 관혈적 정복술을 요한다. 본 증례는 도수 정복되지않는 슬관절 탈구에 대한 관절경적 치료 경험으로 자기공명 영상에서 정복을 방해하는 내측 인대 및 관절낭 구조물을 관찰하고 관절경 검사로 확인한 후 대퇴골 내측와가 완전히 관찰되고 관절이 정복 될 때까지 끼어있는 조직을 제거하였으며 인대 봉합이나 재건술은 시행하지 않았다. 술 후 약 4주간의 신전상태에서 고정 후 점진적인 관절운동 및 체중부하 보행을 허용하였다. 3년 추시 관찰에서 경도의 슬관절 불안정성은 있었으나 일상생활에 지장 없었으며 정상범위의 관절운동범위를 회복하였다.
