BACKGROUND There is controversy regarding the necessity of reconstructing both the posterolateral and anteromedial bundles of the anterior cruciate ligament. HYPOTHESIS A laterally oriented transtibial drilled femoral tunnel replaces portions of the femoral footprints of the anteromedial and posterolateral bundles of the anterior cruciate ligament. STUDY DESIGN Descriptive laboratory study....

The significance of the posterior cruciate ligament in the stability of the knee was investigated in dogs and it was compared with that of the anterior cruciate ligament by studying the changes produced in the knee after transection of either ligament. Osteophyte formation and changes in articular cartilage were less prominent after division of the posterior cruciate ligament. A complete longit...

BACKGROUND Anatomical reconstruction techniques that can restore normal joint kinematics without increasing surgical complications could potentially improve clinical outcomes and help manage anterior cruciate ligament injuries more efficiently. HYPOTHESIS Single-tunnel double-bundle anterior cruciate ligament reconstruction with anatomical placement of hamstring tendon graft can more closely ...

Meniscal injury has been well documented in association with injury to the anterior cruciate ligament. The purpose of this study was to evaluate the effect of anterior cruciate ligament transection and reconstruction on meniscal strain. Four differential variable reluctance transducer strain gauges were placed in the medial and lateral menisci of nine cadaveric knees. Each specimen was mounted ...

PURPOSE The purpose of the study was to compare frequency of meniscal repair to partial meniscectomy in patients undergoing anterior cruciate ligament reconstruction using the American Board of Orthopaedic Surgeons (ABOS) database. HYPOTHESES (1) Practice patterns are similar with respect to geographic region. (2) Surgeons with fellowship training perform more meniscal repairs compared with g...

introduction: anterior cruciate ligament (acl) rupture is one of the most common sport injuries. despite present progresses in conservative and surgical treatment methods for acl, the rate of return to pre-injury level (rtp) is low. fear of movement/reinjury (kinesiophobia) is a major hindrance to rtp in these patients. the aim of the following research was to investigate functional tests’ effe...

BACKGROUND Septic arthritis after arthroscopic anterior cruciate ligament reconstruction is a rare complication. In the literature, several different managements are proposed. HYPOTHESIS The graft can be retained during treatment of a septic arthritis after anterior cruciate ligament reconstruction. STUDY DESIGN Case series; Level of evidence, 4. METHODS A retrospective analysis of knee j...

This study assessed the tensile properties of hamstring and patellar tendon anterior cruciate ligament reconstructions in older cadaveric knees (age range, 48 to 79 years). Mechanical testing to failure was conducted by translating the tibia anteriorly at 1 mm/sec with the knee in 20 degrees of flexion. The strongest gracilis-semitendinosus graft fixation technique (103% of intact anterior cruc...

BACKGROUND Noncontact anterior cruciate ligament injuries occur two to eight times more often in women than in men. Changes in ligament laxity and strength have been associated with female hormones such as relaxin. HYPOTHESIS Relaxin receptors are present within the female anterior cruciate ligament. STUDY DESIGN Controlled laboratory study. METHODS Remnants of anterior cruciate ligament ...
