BACKGROUND Three-dimensional (3D) reconstructed computed tomography (CT) is crucial for the reliable and accurate evaluation of tunnel enlargement after anterior cruciate ligament (ACL) reconstruction. The purposes of this study were to evaluate the tibial tunnel enlargement at the tunnel aperture and inside the tunnel and to clarify the morphological change at the tunnel footprint 1 year after...

Anterior cruciate ligament (ACL) injuries are one of the most common injuries in orthopaedics. ACL injury can be treated either surgically or non-surgically. When surgery is performed, the torn ligament is replaced with a new tissue that will turn into ligament over time. The two main options are autograft, which means that the tissue used to reconstruct the ACL comes from you, and allograft, w...

The first three-dimensional (3D) reconstruction was performed by Born (1883) and His (1885) using serial sections. Since then, a variety of reconstruction techniques have been developed, and the construction of physical models has become important in anatomy. The first computer-aided 3D reconstruction was achieved by Glaser and Van der Loos in 1965. With the improvements in both computer hardwa...

AIM Identify injury-related, patient-reported and treatment-related prognostic factors for 5-year outcomes in acutely ACL-ruptured individuals managed with early reconstruction plus exercise therapy, exercise therapy plus delayed reconstruction or exercise therapy alone. METHODS Exploratory analysis of the Knee Anterior Cruciate Ligament, Nonsurgical versus Surgical Treatment (KANON) trial (I...

T he more we learn, the more we often realize how much we don't know. Twenty-five years ago, I thought we had the anterior cruciate ligament (ACL) dilemma all figured out: arthroscopic technique, patellar tendon grafts, meniscus repair, and immediate motion. Everything looked good clinically until we started seeing the results of long-term outcome studies. 2 I must admit I've been missing some ...

there is controversy in the literature regarding a number of topics related to anterior cruciate ligament (acl)reconstruction. the purpose of this article is to answer the following questions: 1) bone patellar tendon bone (bptb) reconstruction or hamstring reconstruction (hr); 2) double bundle or single bundle; 3) allograft or authograft; 4) early or late reconstruction; 5) rate of return to sp...

Background: Arthroscopic reconstruction of ACL is an effective method to restore knee stability after ACL rupture.Postoperative septic arthritis (SA) is very uncommon while the incidence of serious complications range between0.14% and 1.8%. Some of the devastating consequences of septic arthritis can encompass hyaline cartilage damage,arthrofibrosis, and in rare cases amputation. The purpose of...

PURPOSE To compare femoral graft bending angles and femoral tunnel geometries between the transportal (TP) and outside-in (OI) techniques after anatomic double-bundle (DB) anterior cruciate ligament (ACL) reconstruction. METHODS Thirty-nine patients underwent DB ACL reconstruction with the TP and OI techniques. They were randomized on the day of surgery to either the TP group (group I, 21 cas...
