BACKGROUND The knowledge of muscle activation patterns when doing a certain task in subjects with anterior cruciate ligament deficiency could help to improve their rehabilitation treatment. The goal of this study is to identify differences in such patterns between anterior cruciate ligament-deficient and healthy subjects during walking. METHODS Electromyographic data for eight muscles were me...

PURPOSE To survey the current practice of unicompartmental knee arthroplasty (UKA) in the United Kingdom. METHODS Questionnaires were sent to all 341 local members of the British Association for Surgery of the Knee to inquire into their practice of UKA, including clinical indications, preoperative investigations, surgical approach, preferences in implant design, and the role of UKA in relatio...

Purpose  The aim of this review was to analyze the current literature on osteoarthritic evolution of knees without any combined meniscal or ligament lesions undergoing anterior cruciate ligament (ACL) reconstruction. Methods  A PubMed/MEDLINE research was performed using the following keywords: "Anterior Cruciate Ligament Reconstruction" [Mesh] AND "Osteoarthritis, Knee" [Mesh]. Only English la...

Background: Knee extension torque control decreases after anterior cruciate ligament (ACL) rupture. There is a controversy in neuromuscular control changes on the uninvolved side. We intended to evaluate the steadiness and accuracy of quadriceps muscle control in the healthy and deficient sides of people with acute ACL rupture.    Methods: In this cross-sectional study, thirteen men with ACL r...

BACKGROUND It is now well documented that women are more likely to suffer anterior cruciate ligament injuries than are men. A few studies have examined gender differences in the outcome of anterior cruciate ligament reconstruction with patellar tendon graft and hamstring tendon with EndoButton fixation, but no well-controlled studies have specifically compared men and women after anterior cruci...

BACKGROUND Failure rates of knee ligament surgery may be high, and the impact of osseous alignment on surgical outcome remains controversial. Basic science studies have demonstrated that osseous malalignment can negatively affect ligament strain and that realignment procedures may improve knee joint stability. HYPOTHESIS/PURPOSE The purpose of this review was to summarize the clinical evidenc...

BACKGROUND Long-term outcome after anterior cruciate ligament injury among top-level pivoting athletes is unknown. PURPOSE To evaluate outcome among competitive team handball players after anterior cruciate ligament injury. STUDY DESIGN Prospective cohort study. METHODS A previously studied group of 86 elite players who had an anterior cruciate ligament rupture were invited to participate...

A 24 year old otherwise healthy male was presented with a chief complaint of giving way in the left knee. MRI reportedcomplete anterior cruciate ligament (ACL) tearing. Arthroscopy showed ACL agenesis, ring-shaped lateral meniscus,and an anomalous thick band extending from the anterior horn of the lateral meniscus to the intercondylar notch of thelateral femoral condyle, which...

BACKGROUND There is limited insight into the mechanisms of anterior cruciate ligament injuries in alpine skiing, particularly among professional ski racers. PURPOSE This study was undertaken to qualitatively describe the mechanisms of anterior cruciate ligament injury in World Cup alpine skiing. STUDY DESIGN Case series; Level of evidence, 4. METHODS Twenty cases of anterior cruciate liga...

BACKGROUND Rotational knee movement after reconstruction of the anterior cruciate ligament has been difficult to quantify. The purpose of this study was to identify in vivo whether a more horizontal placement of the femoral tunnel (in the ten o'clock position rather than in the eleven o'clock position) can restore rotational kinematics, during highly demanding dynamic activities, in a knee in w...
