Recently, the interest on anatomical ACL reconstruction with double bundle technique is increased to reproduce the original load distribution, and kinematics of the knee. We developed an arthroscopic double bundle ACL reconstruction technique using autogenous quadriceps tendon with 2 splitted graft and patellar bone plug. The anteromedial bundle and posteolateral bundle of the ACL is replicated with each splitted graft of quadriceps tendon and fixed with biodegradable interference screw on the 2 femoral tunnels. The patellar bone plug of quadriceps tendon is fixed with biodegradable interference screw within the 1 tibial tunnel. We suggest that our technique using quadriceps tendon may be an alternative in arthroscopic double bundle ACL reconstruction.

Optimal treatment of the torn anterior cruciate ligament (ACL) remains controversial. The complexity of surgically reproducing the natural biomechanical and anatomical function of the ACL has led to a diversity of reconstructive procedures. Controversy continues to exist regarding the best reconstructive procedure for the ACL deficient knee, but currently, there is no ideal method. Because of the increased frequency of ACL injury and the functional impairment resulting from that, the role of mechanoreceptors in the ACL recently has attracted considerable attention. Proper reconstruction of the ruptured ACL does not always have good results. Success after operation may depend not only on the mechanical stability but also on the quality of recovery of proprioception. It is well known that most ACL are ruptured in proximal half and most mechanoreceptors have been reported to be located in the subsynovial layer and near the tibial insertion of the ACL. Expected roles of tibial remnant is to enhance the revascularization and cellular proliferation of the graft, to preserve proprioceptive function, and to be able to acquire anatomical placement of the graft without roof impingement. The remnant of the ruptured ACL has been removed to clearly visualize the ACL footprint or decrease the risk of impingement and Cyclops lesion in most current techniques for ACL reconstruction. Therefore it seems reasonable to assume that preserving the tibial remnant as much as possible as a source of reinnervation, if technically possible without causing impingement, would be of potential benefit to the patient. In addition, it will facilitate the vascular ingrowth and ligamentization of the grafted ACL.

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.

스포츠 활동과 사고로 인하여 전방십자인대 재건술이 많이 증가하고 있으며 여러 종류의 자가 및 동종이식건이 많이 사용되어지고 있다. 자가 골-슬개건-골을 이용한 전방십자인대 재건술이 제일 대표적인 이식건으로 사용되고 있으나 공여부의 합병증과 전방슬관절통 등의 문제가 발생될 수 있으며 환자에 따라서 이러한 문제를 줄일 수 있는 다른 이식건의 사용도 필요할 수 있다. 여러 이식건의 생역학적인 특성, 장점 및 단점, 합병증을 충분히 이해함으로써 환자 개인에 맞는 적절한 이식건을 선택할 수 있으며 수술후 환자의 만족도를 높일 수 있을 것으로 생각된다

Purpose: The purpose of this study was to investigate the effect of strengthening exercises of hip abductors on muscle strength and ambulation for patients with ACL reconstruction. Methods: The subjects were randomly assigned to the intervention group (general exercise plus strengthening of hip abductors) or the control group (general exercise without the strengthening of hip abductors). Both groups participated in a six-week exercise protocol after the surgery for ACL reconstruction. The knee strength test (quadriceps, hamstring, hip abductor) and gait analysis were performed in pretest and post-test. Results: Muscle strength was measured using the Biodex system III model (Biodex Medical System, Inc, NY, US). The results showed no significant difference in knee strength (quadriceps, hamstring) between the two groups (p>0.05), however, there was a significant difference in hip abductors (p<0.05). The gait analysis was measured with Gaitrite system (CIR System Inc, US). Results of comparison between groups showed a significant increase in the step length of both groups. (p<0.05), and there was a significant difference in the affected leg of the intervention group(p<0.05). Conclusion: Exercise of hip abductors for patients with ACL reconstruction provides significant benefits with respect to improvement of muscle strength in hip abductors, increasing the stride. This result indicates that a training program designed for ACL reconstruction patients should include strengthening of the hip abductor. We think that further study is needed to determine the relationship of hip muscles and knee joint for patients with ACL reconstruction.

Between March 1992 and December 1995 at St. Paul's, Holy Family, St. Vincent and Eui Jung Bu St. Mary Hospitals Catholic University, two hundred and eighty patients underwent arthroscopic anterior cruciate ligament(ACL) reconstruction using central one-third bone-patellar tendon-bone autograft. Nine of these patients had limitation of motion(LOM) defined as a knee flexion contracture greater than 10o or less than 125o of passive knee flexion. This study analyzes the causes of LOM after ACL reconstruction as well as the results after passive manipulation or arthroscopic adhesiolysis under anesthesia for LOM. The results are as follows: 1. Out of nine patients, initially three had isolated ACL injuries and six had combined injuries. Seven of nine cases were perfomed by ACL reconstruction within four weeks and two were performed after four weeks following injury. 2. Treatment for LOM after ACL reconstruction was done after 5.5 months on average. 3. Arthroscopic adhesiolysis was done in 5 cases. There were fibrous adhesions at suprapatellar pouch and femoral intercondylar notch in all cases, respectively, infrapatellar fat pad in 3 cases and medial para patellar gutter in 2 cases. Two patients had a fibrous nodule, "cyclops" lesion, which formed anterior to the ACL graft. 4. Range of motion and Lysholm knee score were much improved following passive manipulation or arthroscopic adhesiolysis under anesthesia for LOM.

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.

In order to obtain a good result in Arthroscopic ACL Reconstruction by immediate postoperative physical therapy, sufficient analgesia was needed. This study analyzes the analgesic effect of the intra-articular injection with ketorolac, Morphine together with bupivacaine in 80 male patients who had Arthroscopic ACL Reconstruction. On completion of the surgery under spinal anesthesia, the knee was injected with 30ml of 0.25% bupivacaine. Each of the study group received ketorolac and/or morphine, either through parenteral or intra-articular. Total amount of the drug used by Patient Controlled Analgesia(PCA) and Visual Analgesia Scale(VAS) for pain were measured and analyzed. The group which received intra-articular ketorolac or Morphine had a better analgesic effect than other group which received none. The group which received both did not do better in analgesic effect. Intra-articular infusion with either ketorolac or Morphine improved postoperative analgesia in Arthroscopic ACL Reconstruction surgery. However, combined injection did not offer more advantage.

Numerous techniques of anterior cruciate ligament (ACL) reconstruction have been described in literature. All have inherent advantages and disadvantages. The central one-third patellar tendon and hamstring tendons are the most commonly used autogenous tissues for replacement of a torn anterior cruciate ligament. Although the central one-third patellar tendon is considered to be 'the gold standard' for replacement of torn ACL. equivalent results have been reported using hamstring tendon grafts. Autogenous hamstring grafts provide adequate strength while avoiding donor site morbidity associated with bone-tendon-bone harvest. $EndoButton^{\circledR}$ femoral fixation allows precise femoral tunnel placement without a second incison. The purpose of this article is to describe surgical techniques using a quadrupled semitendinosus tendon and $EndoButton^{\circledR}$ fixation, and review the results of replacement of ACL.
