BACKGROUND Despite increasing attention on fixation of a soft tissue anterior cruciate ligament graft in the tibia, there have been no studies on the use of a bone dowel as a joint line fixation device for promoting fixation properties, especially stiffness at the time of implantation. PURPOSE To determine whether compacting a bone dowel into the tibial tunnel improves fixation stiffness, yie...

Primary anterior cruciate ligament (ACL) reconstruction is considered a successful surgical procedure, but the results reported for revision ACL surgery are less satisfactory. The most common cause of technical failure in primary reconstruction is tunnel misplacement, particularly on the femoral side, although an anterior placement of the tibial tunnel may lead to graft impingement and failure....

INTRODUCTION Reconstructing a torn anterior cruciate ligament (ACL) in a knee that has had prior ACL surgery presents challenges, especially if multiple procedures have been done in the past. Revision ACL surgery will continue to become more common as the number of primary ACL reconstruction procedures continues to increase. A common problem faced by the surgeon in the revision setting is an en...

  Background: Ligament reconstruction is a common procedure in orthopedic surgery. Although several popular techniques are currently in use, new methods are proposed for secure fixation of the tendon graft into the bone tunnel. Purposes: We sought to introduce our new technique of Bashti bone plug for fixation of soft tissue graft in anterior cruciate ligament (ACL) reconstruction and to compar...

The use of pin fixation for grafts in the femoral tunnel in anterior cruciate ligament (ACL) reconstruction is becoming more popular. The transtibial stiff femoral guides are necessary to ensure that the pins fix the graft. However, the cross pins can sometimes miss the femoral tunnel. As a result of some technical problems that we encountered, we introduced an extra step in the technique of th...

OBJECTIVE Increase in ACL (anterior cruciate ligament) reconstructions has led to a higher prevalence of patients with postoperative symptoms which require investigation. We aimed to investigate the utility of magnetic resonance imaging (MRI) and computer tomography (CT) in determining tunnel size and graft obliquity after single bundle ACL reconstruction. PATIENTS AND METHODS A retrospective...

A prospective, observational study was performed to document the serial changes in the magnetic resonance signal of devascularized, hamstring ACL autografts during the 1st year of implantation. Twenty-one ACL deficient knees (14 chronic, 7 acute) were reconstructed. Instability developed in five knees within the first 6 months of graft implantation (24%). Magnetic resonance examinations were pe...

BACKGROUND Radiographic imaging is a valuable tool in clinical practice for quick anatomical assessment. We aimed to radiographically assess (A) the anterior cruciate ligament (ACL) graft tunnel location after anatomic single-bundle (SB) reconstruction and (B) the effects of extremity positioning on the localization of the orifice of the tunnel in the distal femur in comparison with Blumensaat'...

BACKGROUND Improved biomechanical and clinical outcomes are seen when the femoral tunnels of the anterior cruciate ligament (ACL) are placed in the center of the femoral insertion. The transtibial (TT) technique has been shown to be less capable of this than an anteromedial (AM) portal approach but is more familiar to surgeons and less technically challenging. A hybrid transtibial (HTT) techniq...

Because of the complications of impingement of anterior cruciate ligament grafts on the intercondylar roof and because current surgical procedures locate the tibial tunnel such that impingement is avoided during passive but not active extension, the objectives of this study were to determine if (a) active extension precipitates and aggravates roof impingement, and (b) a roofplasty mitigates the...
