The anterior cruciate ligament is the most commonly disrupted ligament in the knee in high-performance athletes. Most recently, advancements in surgical technique and graft fixation have enabled athletes to participate in early postoperative rehabilitation, focusing on range of motion and progressing to patellar mobilization, strengthening, and neuromuscular control. Several rehabilitation prot...

Five hundred and seventy one matches in the Australian Football League [AFL] had ground hardness measured using a Penetrometer, over the period 1997-2000. The method used was 3 drops at each of 20 locations over the playing field on the morning before games. Anterior Cruciate Ligament [ACL] injuries were recorded using an ongoing injury surveillance system. There was a non-significant trend tow...

BACKGROUND The number of anterior cruciate ligament injuries in female athletes exceeds that in male athletes at similar competitive levels. This difference has been attributed by some authors to hormone-mediated alteration in knee laxity in women. HYPOTHESIS Sheep anterior cruciate and medial collateral ligament strength and stiffness are not altered by administration for 6 months of estroge...

Isolated posterior cruciate ligament (PCL) tears are much less frequent than anterior cruciate ligament (ACL) tears.Abrupt posterior tibial translation (such as dashboard impact), falls in hyperflexion and direct hyperextension trauma are the most frequent mechanisms of production.The anterolateral bundle represents two-thirds of PCL mass and is reconstructed in single-bundle techniques.The PCL...

This study was conducted to retrospectively analyzed the outcome of 192 total knee arthroplasties in 132 patients with rheumatoid arthritis (118 women, 14 men). The Okayama Mark II prosthesis, which requires the posterior cruciate ligament (PCL) to be resected, was used in 83 knees (group I), the Mark II prosthesis, which allows the PCL to be retained, was used in 68 knees (group II), and the n...

Posterior cruciate ligament reconstruction using the transtibial technique provides successful clinical outcomes. However, a bone-patellar tendon-bone (BTB) autograft with the transtibial technique has not been used by some surgeons because of concerns with graft passage from the tibial to the femoral tunnels (sharp turn) that can damage graft fibers. In the present surgical technique, an arthr...

BACKGROUND Female college basketball and soccer athletes have higher rates of anterior cruciate ligament injury than do their male counterparts. Rates of anterior cruciate ligament injuries for women and men in collegiate lacrosse have not been examined. Understanding anterior cruciate ligament injury patterns in lacrosse, a full-contact sport for men and noncontact sport for women, could furth...
