BACKGROUND The purpose of this study was to quantify the meniscal root anatomy of the New Zealand white rabbit to better understand this animal model for future in vitro and in vivo joint degeneration studies. METHODS Ten non-paired fresh frozen New Zealand white rabbit knee stifle joints were carefully disarticulated for this study. Measurements were made for all bony landmarks and ligamento...

Proprioception was measured in two groups of patients following successful total knee arthroplasty (TKA). In one group, the posterior cruciate ligament was retained and an unconstrained cruciate-retaining total knee component was used; in the other group, the posterior cruciate ligament was excised and a cruciate-substituting design was implanted. Threshold to detection of passive motion was qu...

Injuries to the medial collateral ligament (MCL) are very common and there seems to be a consensus supporting the conservative management of grade I and II tears. Grade III tears are also usually treated conservatively unless associated with injuries to the anterior cruciate ligament or posterior cruciate ligament. This article outlines rehabilitation programs for conservative treatment of MCL ...

Disruption of the major ligaments of the knee was seen in six young men, five parachutists and a house painter, after what we have termed abduction-traction injury. This unusual complaint results from the application of a sudden block to the ankle while falling head first, leading to traction and abduction of the knee. All the patients underwent operations, generally with unsatisfactory results...

The menisco-femoral ligament is one of the most important accessory ligaments of the knee. It extends from the posterior horn of the lateral meniscus to the lateral aspect of the medial femoral condyle close to the femoral attachment of the posterior cruciate ligament. The accessory ligament may run behind or in front of the posterior cruciate ligament and is known either as the posterior menis...

Reverse Segond fracture is an uncommon avulsion fracture of the tibial attachment of the deep portion of the medial collateral ligament of the knee. We report a reverse Segond fracture associated with anterior cruciate ligament tibial avulsion fracture and anteromedial tibial rim fracture. Unlike previous reports, the combination of reverse Segond fracture, anteromedial tibial rim fracture, and...

OBJECTIVE To present the diagnostic and clinical features of a ganglion cyst located on the posterior cruciate ligament and create awareness amongst clinicians of this uncommon diagnosis. CLINICAL FEATURES A 24-year old woman complaining of intermittent left knee pain brought on by an increase in mileage during her training for a half-marathon. A diagnosis of mild chondromalacia patella and a...

We describe the modification of an existing method of ligament strain measurement at the knee joint in detail. At ten fresh joint specimens we used that technique where strain gauges are attached to the ligamentous insertions and origins. We both improved the preparation of the attachment site and the application of the strain gauges. In a special apparatus the specimens were moved from 0 degre...

This PCL pushes the tibia forwards on the femur and hence, is responsible for maintaining congruency of the joint. By virtue of its position at the back of the joint, it also acts like a pivot point about which the rest of the knee moves. When the PCL is damaged, the tibia slides backwards on the femur and, in a complete tear, it moves about 12 mm in that direction. When this happens, the joint...
