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.

The all inside anterior cruciate ligament reconstruction technique places an anterior ligament substitutes within two bony sockets rather than hone tunnel. This approach is accomplished through arthroscopic three portal which avoids the surgical exposure and morbidity associated with creating traditional bone tunnel. This technique has several distinct advantages when compared with the traditional ACL reconstruction through the bone tunnels. It offers the surgeon a less morbid method for ACL reconstruction that positions an ACL substitute at the anatomic attachment sites of the original ACL with two bone sockets, obviating the need for traditional bone tunnels. Graft fixation at or near the anatomic attachment points of the original ACL minimizes creep with early range of motion and reduces the abrasive 'wind-shield wipe' motion of the graft which occur with bone plugs positioned inside bone tunnels. The sagittal posterior angle to the tibial socket increases fixation strength to pullout with anterior translation force for the tibia on the femur. This technique is not graft specific and can accomodate any graft in which graft length can be customized to the intraarticular native ACL length.

Anterior Cruciate Ligament (ACL) plays an important biomechanical role for the stability of knee joint. ACL injury often leads to injuries of articular cartilage, menisci, or other supporting structures, and subsequent development of degenerative arthritis. Controversies still exist in the best treatment modalities of ACL injuries. hut the author considers it most important to make the appropriate patient selection for operative reconstruction or nonoperative treatment. and describes the treatment principles of ACL injury, including diagnosis, patient selection and the treatment modalities for successful treatment of ACL injury.

1986년 1월부터 1988년 4월까지 본대학 안과학교실에서 시행한 26례의 수정체후낭적출술 및 전방렌즈 삽입술 중 planned ACL 15례와 unplanned ACL 11례를 대상으로 Goldmann applanation tonometer를 사용하여 안압을 측정하고 각 요인에 따라 수술전과 수술후 안압의 차이를 비교 분석하여 보았던 바 다음과 같은 결론을 얻었다. 1. 술전 안압과 술후 안압에 대한 통계학적 유의성은 양군 모두 없었다. 2. planned ACL군에서는 53.4%, unplanned ACL군에서는 54.5%에서 안압상승이 있었으나 두군 모두 정상범위내로 안압차이에 대한 통계학적 유의성은 없었다. 3. 안압변화의 평균치는 planned ACL군에서 1.07mmHg의 상승이 있었고 unplanned ACL군에서는 0.18mmHg의 안압하강이 있었다. 4. 각 군의 나이 분포도에 대한 양군간의 안압변화에 대한 유의성은 없었다. 5. 술후 3개월이 경과한 뒤의 안압 변화는 술전 안압과 비교하여 양군 모두 통계학적 유의성은 없었다.

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.

A torn anterior cruciate ligament(ACL) is the most common serious ligamentous injury to the knee joint. The incidence of ACL tears seems to be increasing, at least partly as a result of the increasing participation of individuals of all ages in high-risk sports. The most commonly used graft source for ACL reconstruction is the autogenous bone-patellar tendon-bone graft unit. Despite a good success record. postoperative complications, such as infection, patellar contracture/patellar baja, patellar fracture, rupture of the patellar tendon, graft failure without reinjury, can occur following ACL surgery. The purpose of this paper is to provide guidelines regarding the key points of the reconstructive procedure in a sequence and how to prevent or minimize the complications that can follow ACL reconstructive surgery. We want this knowledge can help orthopaedic surgeons to understand the reasons for previous and current successes and failures of reconstruction of the ACL, and it can help them to plan the care of patients who have an injury of the ligament.

전방 십자인대 재건술 후 발생하는 전경골 낭종은 드물게 발생하는 질환이다. 저자들은 전경골근 동종건을 이용한 전십자인대 재재건술 후 발생한 전경골 낭종을 보고하고자 한다. 본 합병증은 경골 터널을 통하여 관절과 낭종이 이어져 발생한 것으로 추정된다. 저자들은 전십자 인대 재건술 후 전경골 낭종의 발생 가능성이 있음을 보고하고자 한다.

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.

Anterior knee pain is a major problem among adolescents and young adults especially those who participates in sports. The most common pathogenesis of anterior knee pain can arise from compression and shear forces in the patellofemoral joint. It is also caused by impingement of infrapatellar fat pad. Fat pad impingement can occur when the fat pad becomes swollen and inflamed due to a direct blow or chronic irritation. As a result, the bottom tip (or inferior pole) of the patella can pinch the fat pad. One of the many causes of swollen fat pad can be secondary to anterior cruciate ligament (ACL) injury. The aim of this study was to compare the infrapatellar fat pad volume in patients with acute ACL injury and a group of age-, gender-, and activity- matched controls with intact ligament. Axial magnetic resonance (MR) images have been performed on 32 patients with torn ACL and 40 control patients. The volume of the fat pad was measured digitally from MR image by using a 3d Reconstruction software, ellipsoidal approximation, and a MATLAB code. The results were compared between patients with torn ACL and control group. Patients with a torn ACL had a significantly larger fat pad than the controls (P=0.01). There was no significant difference between the methods used to measure the infrapatellar fat pad volume (P=0.83-0.87). Thus, lesions of the infrapatellar fat pad is often associated with ACL injury.
