Full radial posterior lateral meniscus root tears are frequently associated with injuries to the anterior cruciate ligament. Left unrepaired, they result in loss of the meniscus hoop stress function and can lead to overload of the lateral compartment and early degenerative changes. Arthroscopic suture repairs show successful results with long-term follow-up. However, previously described suture...

Medical collateral ligament injuries are among the most common knee injuries for the athletic population. Immobilization once was the accepted course of treatment for MCL injuries but research has demonstrated the ineffectiveness of this approach. The knee is second only to the ankle in frequency of injuries in competitive sports and often more severe. Ruptures to the anterior cruciate ligament...

What are the most common causes of anterior cruciate ligament (ACL) injury in athletes? The most common causes for ACL injury in athletes are noncontact, twisting injuries that involved a pivoting motion. For example, in sports such as soccer, athletes frequently perform motions that plant and twist the lower extremities, putting those who play soccer at one of the highest likelihoods of ACL in...

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...

Materials and Methods A case review was performed for 18 consecutive patients who presented with multiligamentous knee injuries. These patients were managed over a 34-month period from 2010 to 2013 by the senior author who managed majority of the cases in our centre. Our institution is a 1300-bed Level 1 trauma centre that manages the highest number of trauma patients in our locality.3 A multil...

Enneking et al. examined the process of local spread of primary bone and soft tissue tumors of the extremities and proposed a “surgical staging system” and “the concept of compartment and anatomic barriers.”17 Applying this concept to the spine, we studied the histology of 19 vertebral tumor specimens resected by TES. We found that the following tissues served as barriers to spinal tumor progre...

A motion-based Inverse Kinematics Knee (IKK) model was developed for Total Knee Replacement (TKR) joints. By tracking a sequence of passive knee motion, the IKK model estimated ligament properties such as insertion locations. The formulation of the IKK model embedded a Forward Kinematics Knee (FKK) model in a numerical optimization algorithm known as the Unscented Kalman Filter. Simulation resu...
