최근 전방십자인대 손상의 치료에 남아있는 인대 다발이 이식건의 생물학적 치유를 도우며 고유 수용감각(proprioception) 기능을 유지할 뿐만 아니라 슬관절의 전방 전위 억제의 생역학적 기능을 가지는 것으로 연구되고 있다. 이러한 이론을 바탕으로 남아있는 전방십자인대를 보존하는 노력들은 다양하게 시도되고 있다. 전방십자인대 손상의 자연 경과는 아직도 논란이 되고 있으나 선택적인 환자에 있어서 보존적 치료는 비교적 좋은 결과를 얻을 수 있으므로 불필요한 재건술을 줄일 수 있다. 최근 시도되고 있는 선택적 다발 재건술 및 남아있는 다발을 보존하는 전방십자인대 재건 수술 수기들은 다양한 방법으로 시도되고 있으며 남아있는 다발을 보존하는 장점이 있으나 협소한 적응증을 가진다. 저자들의 남아있는 다발을 보존하는 전방십자인대 재건술은 자가 슬괵건을 이용한 단일다발 재건술을 시행하면서 잔존하는 이완된 다발에 봉합사를 통과시킨 후 봉합사를 추가적인 터널 없이 bioabsorbable cross pin (RIGIDfix system, Mitek, Johnson & Johnson, USA) 구멍을 통하여 당기고 고정하는 방법이다. 전방십자인대 재건술시 남아있는 다발을 보존하는 방법은 이식건의 생물학적 치유을 촉진하고 또한 경골 부착부에 남아있는 기계수용체를 보존하므로 기능적 회복에 도움이 될 것으로 기대된다. 저자들의 방법은 비교적 광범위한 적응증을 가지며 적은 합병증으로 남아있는 다발을 효과적으로 보존할 수 있는 술식으로 전방십자인대 수술시 좋은 치료 선택의 하나로 사료된다.

The concept of double-bundle ACL reconstruction was introduced recently to restore the anatomical and biomechanical functions of the native ACL. According to anatomical and biomechanical studies, the separate reconstruction of anteromedial and posterolateral bundle expect to increase the overall postoperative stability and clinical results compared to single-bundle ACL reconstruction. But there is still a lack of available clinical outcome studies with sufficient follow-up to demonstrate the real advantages of double-bundle ACL reconstruction. The purpose of this article is to review the evidence to support double-bundle technique and to address controversies existing over the usefulness of this technique.

The review provides updated concepts regard to the anatomy of the anterior cruciate ligament (ACL) footprints. The concept of anatomical ACL reconstruction, in which the graft is placed in the native ACL insertion area, has been introduced. However, there is still no consensus on the anatomical positioning of the femoral and tibial tunnel. In this study, authors review and update the literature regarding the tunnel position for anatomical ACL reconstruction.

With the increasing number of primary ACL reconstructions, revision surgery has become more frequent. Despite arthroscopic technique and treatment advancements, the current methods of reconstruction are far from perfect that a significant number of patients have an unsatisfactory. This article discusses the multiple mechanisms of failure of primary intra-articular ACL reconstruction and provides the orthopaedic surgeon with a systematic approach to the evaluation and treatment of failed ACL reconstructions.

The incidence of anterior cruciate ligament tears is increasing as a result of the increasing participation of individuals of all ages in high-risk sports. Endoscopic anterior cruciate ligament reconstruction using autogenous central third bone-patellar tendon-bone graft is the most commonly used method. With regard to BPTB graft as the go]d standard in ACL reconstruction, there are no data that refute this claim to date. Author reviewed the biomechanical properties, donor site morbidity and selection of the bone-patellar tendon-bone graft and described the surgical technique of endoscopic ACL reconstruction using BPTB autograft.

Purpose : The purpose was to evaluate the early result of revision of failed anterior cruciate ligament (ACL) reconstruction. Materials and Methods : From August 1997 to February 2002, this report presents the findings of 18 patients who had revision surgery for failed ACL reconstruction. There was an average of 39 $(7\~120)$months from index procedure to the time of revision. Allografts were used in 14 $(78\%)$cases and autografts were used in 4 $(22\%)$cases and the revision procedures were assisted by arthroscopic technique. The majority of chief complaints were instability in 16 $(89\%)$cases. Sixteen $(89\%)$ cases had 1 previous reconstruction, 2 $(11\%)$ cases had 2. Before and after revision, patients were evaluated by Lachman test, pivot shift test, KT 2000, radiographs, Lysholm score and HSS score and subjective satisfaction. Results : Average length of followup was 27 $(12\~60)$months. Preoperatively, all cases were positive in Lachman test and pivot shift test. After revision the majority of cases were negative. Objectively improving stability was confirmed by KT 2000 and all average KT 2000 was 7.75 $(3.5\~12.5)$mm preoperatively and 2.36 $(1.0\~6.0)$mm at final followup. Lysholm score and HSS score were also improved from 72.6 $(66\~77)$ and 72.5 $(68\~78)$ preoperatively to 89.2 $(80\~92)$ and 88.2 $(81\~92)$ at final followup. Most $(89\%)$ of patients were satisfied with their results. The most common causes of failed ACL reconstruction were malposition of femoral tunnel in 11 $(61\%)$cases. Conclusion : Arthroscopic revision ACL surgery with adequate graft for failed ACL reconstruction was successful in objectively and subjectively improving stability. However, considering the most common causes of failure after ACL reconstruction were errors in surgical technique, it is important that the primary ACL reconstruction should be performed with correct surgical technique.

후방십자인대 및 후외측인대 재건술 후 결과는 많은 발전이 있었지만, evidence medicine의 측면에서 재활 방법에 관한 전향적 연구는 없다. 현재까지의 재활 방법은 다양하게 소개되었지만 전방십자인대 재건술처럼 가속 재활을 하는 것은 바람직스럽지 않다. 후방십자인대, 후외측인대 그리고 다발성 인대 재건술 후 재활은 수술 방법과 환자의 재건된 인대의 상태, 하지 정렬 등에 따라서 개별화하여 점진적으로 진행하여야 할 것이고, 재활기간 동안 의사의 세심한 관찰이 필요하다.

Purpose: As the number of the anterior cruciate ligament (ACL) reconstruction has increased, the incidence of revision of ACL reconstruction due to reconstruction failure has been also increased. Therefore, authors analyzed the reason of the failure of ACL reconstruction and the clinical result of the ACL revision. Materials and methods: From February 1998 to July 2010, we selected 36 cases which was followed at least 12months after the ACL reconstruction failure. Duration from reconstruction to revision, the average duration was 60 months (5~334) and on first reconstruction, we used allograft on 23 cases (63.9%) and autograft on 13 cases (36.1%). For the main symptom of ACL reconstruction failure, instability was the most common symptom, and 35 cases (97.5%) were undergone only one reconstruction and 1case (2.5%) was undergone two reconstruction. Clinical results were evaluated by Lysholm knee joint score, pivot shift test, and Telos device. Results: Average follow-up duration of the patients was 21 months (12~40), and the reason for the ACL reconstruction failure, trauma was most common by 19 cases (52.8%), malposition of the femoral tunnel was 13 cases (36.1%), malposition of the tibia tunnel was 1case (2.8%), and failure of osteointegration was 3 cases (8.4%). On performing the ACL revision, we used allograft on 34 cases (94%) and autograft on 2 cases (6%), and 21 cases accompanied injury of the meniscus (medial meniscus 14 cases, lateral meniscus 7 cases). Lysholm knee joint score was improved from 66.5 points, preoperatively to 92 points on last follow-up (p<0.01). In most cases, patients were satisfied (92%) with the operation results. Tegner activity score was also improved from 2.0 points preoperatively to 6.2 points on the last follow-up. On Lachman and pivot sift test, 33 cases and 30 cases were improved to grade I respectively, and on stability test using Telos device, the bilateral difference was improved from mean 15.5 mm preoperatively to 4.5 mm on the last follow-up. Conclusion: After 1 year follow-up, Revision of ACL had a little anterior instability but it showed satisfactory result on clinical result and patient's subjective satisfaction.
