Injuries to the posterior cruciate ligament (PCL) commonly result from frontal automobile crashes when the occupant’s tibia interacts with the intruding knee bolster of the vehicle. The goal of this research study was to better understand injury to the PCL due to this impact scenario and correlate injury with the response of the knee slider of today’s crash test dummies. Over a span of two year...

An isometer, a highly compliant spring-scale device for measuring suture displacement, has been used intraoperatively by surgeons to select the optimal placement of the femoral tunnel for an anterior cruciate ligament graft. The isometer measures the displacement of a suture centered in a tibial tunnel and attached to an intraarticular location on the femur before the femoral tunnel is drilled....

Patella: accounts for 1% of all fractures, most common in ages 20-50 Femoral condyles: these usually fracture when the knee is stressed. Tibial eminence: caused by accidents, such as a blow to the proximal tibia when the knee is flexed, or if the knee is hyperextended during an accident. Usually seen in patients aged 8-14. Tibial tuberosity: more common in men than in women, and in younger pati...

The triple tibial osteotomy (TTO) is a technique which combines the features of tibial tuberosity advancement and wedge osteotomy for the treatment of complete and partial cruciate ligament injuries in dogs. In this paper, the technique is described and the results of a prospective study of 64 consecutive cases are presented. TTO provided a satisfactory clinical outcome in a very high percentag...

Osteochondroma arising from the tibial tuberosity is very rare. We report such a case which mimicked OsgoodSchlatter's disease in an adolescent. A 12 years-old boy presented with swelling over his right proximal tibia of one year duration associated with pain in the last three months. Examination revealed a 4 x 2cm bony mass arising from the proximal tibia. Radiographs revealed an osteochondrom...

BACKGROUND Previous studies have indicated that higher knee joint laxity may be indicative of an increased risk of anterior cruciate ligament (ACL) injuries. Despite the frequent clinical use of knee arthrometry in the evaluation of knee laxity, little data exist to correlate instrumented laxity measures and ACL strain during dynamic high-risk activities. Purpose/ HYPOTHESES The purpose of th...

OBJECTIVES We investigated the biomechanical characteristics of anterior or posterior tibial tunnel placement of the soft tissue graft with a soft tissue interference screw in anterior cruciate ligament (ACL) reconstruction. METHODS Twelve bovine tibiae and digital extensor tendons were divided into two homogeneously equal groups after they were stripped of all soft tissues. Tibial tunnels we...
