A 38-year-old man presented with right knee pain and swelling following a football injury. Magnetic resonance (MR) imaging showed a complete anterior cruciate ligament (ACL) tear and lateral meniscal tears. The torn ACL was repaired with a graft obtained from the semitendinosus muscle, and the menisci were debrided. The mechanisms of injury to the ACL are varied and may be due to direct or indirect contact with the knee as well as with twisting injuries. Knowledge of the ACL's normal anatomy, together with MR imaging technique and understanding of the appearance of the lesion on MR examination, is crucial to aid in the identification of an ACL tear. Diagnosis of an ACL tear should be based on direct MR imaging signs, although indirect signs may be helpful, particularly in chronic tears. Other associated injuries to be aware of include meniscal and other ligamentous injuries. Normal ACL graft and post-ACL graft reconstruction complications are also briefly discussed.

Anterior cruciate ligament (ACL) reconstruction is generally accepted as the most reliable method of re-establishing knee kinematics so as to prevent various symptoms related to the instability and subsequent injuries to the knee. Double bundle ACL reconstruction has emerged as a potential solution for single bundle reconstruction, as the latter can restore anteroposterior stability, but it had limitations for improving the rotational stability. However, double bundle reconstruction is a more complex surgical procedure and it remain unclear whether double bundle reconstruction has better results than single bundle reconstruction on long term follow-up. Recent studies have demonstrated that a femoral tunnel could be created independently of the tibial tunnel and in a more anatomic position by using the anteromedial portal technique, so that that there is better restoration of the rotational stability as well as anterior stability than that with performing the transtibial technique.

The original technique for endoscopic anterior cruciate ligament reconstruction has several potential complications because of constraints imposed by working through the tibial tunnel: improper femoral tunnel placement, violation of the femoral tunnel posterior wall, femoral interferenc screw divergence, graft laceration during screw insertion, and distal tibial bone block prr>trusion. We performed 25 endoscopic anterior cruciate ligament reconstructions with bone-tendon-bone graft using a mo3ified technique that minimizes each of these problems, through the use of a anteromedial portal more centrally and distally placed than the original that portal. Postoperative radiographic review showed femoral screw divergence in 20% of cases (2 in the anteroposterior plane, 2 in the lateral plane and 1 in both planes), but the average angles (AP: 0.52+- 1.85, Lateral: 1.48+-3.30) were insignificant. There was no graft damage during screw insertion or grafttunnel mismatch. We concluded that this modified technique allows simplified, reproducible tunnel and interference screw placement.

As the number of primary reconstructions of the anterior cruciate ligament (ACL) increase, so do the number of revision ACL reconstructions due to failure. Revision ACL reconstruction has several challenges compared to primary ACL reconstruction. Literature review regarding revision ACL reconstruction was performed to discuss the cause of the failure, results of revision, and to assist the decision-making process and approaches to the patients. Usually good functional stability could be obtained after revision ACL reconstruction, but increased incidence of meniscal and cartilage lesions played a role in patient dissatisfaction. To solve issues such as tunnel widening, malposition, and inserted hardware after primary ACL reconstruction, various surgical technique issues were reviewed.

The advances in the knowledge of anatomy, surgical techniques, and fixation devices have led to the improvement of anterior cruciate ligament (ACL) reconstruction over the past 10 years. Nowadays, double bundle and anatomical single bundle ACL reconstruction that more closely restores the normal anatomy of the ACL are becoming popular. Although there is still no definite conclusion whether double bundle ACL reconstruction provides better clinical results than single bundle reconstruction, the trend has shifted to anatomic reconstruction regardless of single bundle or double bundle techniques. We could not find any significant differences in the clinical outcomes and stability after ACL reconstruction according to the type of graft or fixation device. Therefore, surgeons should select an ideal ACL reconstruction according to the patient's condition and surgeon's experience.

PURPOSE: The purpose of this study was to evaluate the efficacy of our technique that allows direct visualization of seating of suspensory devices in anterior cruciate ligament (ACL) reconstruction. MATERIALS AND METHODS: Three different suspensory devices (TightRope RT, RetroButton, and EndoButton) were used in ACL reconstruction using 3 different techniques (outside-in, anteromedial [AM] portal, and transtibial techniques). Positioning of a guiding material and seating pattern of the suspensory devices were evaluated according to the surgical technique and suspensory device used. RESULTS: On the transtibial technique, 21 of total 26 cases (81%) of single bundle reconstructions and 22 of total 22 cases (100%) of double bundle reconstructions required superolateral capsulotomy where buttons were found in 21 of total 21 cases (100%) and 17 of 22 cases (77%), respectively. On the AM portal technique, all patients required capsulotomy and the button was found in only 18 of total 32 cases (56%) even after capsulotomy. On the outside-in technique, all patients required capsulotomy and the button was found in 86 of total 86 cases (100%). CONCLUSIONS: Our technique for direct visualization of seating of the suspensory devices was more effective in outside-in and single bundle transtibial ACL reconstruction. However, it was less effective in double bundle transtibial and AM portal ACL reconstructions.
