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...

BACKGROUND Various surgical techniques to treat posterolateral knee instability have been described. To date, the recommended treatment is an anatomic form of reconstruction in which the 3 key structures of the posterolateral corner (PLC) are addressed: the popliteofibular ligament, the popliteus tendon, and the lateral collateral ligament. PURPOSE/HYPOTHESIS The purpose of this study was to ...

The internal lateral ligament is the ligament most frequently damaged. Usually a few of the upper fibres are torn away from the periosteal attachment at the lower end of the femur. Occasionally, however, the deep fibres which are attached to the internal semilunar cartilage are partially torn without the cartilage being damaged. Occasionally, the external lateral ligament is injured. With more ...

The current study analyzed changes in anterior cruciate ligament (ACL) and lateral collateral ligament stress as a result of mechanical varus. In an exploratory pilot study, progressive mechanical varus was introduced to a male finite element model of the lower limb at different knee flexion angles. Nine situations were analyzed (combinations of 0°, 30°, and 60° knee flexion and 0°, 5°, and 10°...

The objective of this work is to give a complementary description of the hepatic lobulation, the hepatic ligaments and the omenta of the nutria. Thirty nutrias were studied by gross dissection. The liver of the nutria was divided into six lobules as follows: left lateral, left medial, quadrate, right medial, right lateral, and caudate lobes. The caudate lobe was divided into a papillary and a c...

Purpose. A relatively unknown ligamentous structure of the posterolateral corner of the knee joint, the so-called meniscofibular ligament (MFL), was investigated as regards its macroscopic morphology, its histological features, and its reaction to knee movements. Material and Methods. MFL was exposed on 21 fresh-frozen unpaired knee joints. Its microscopic morphology was examined utilizing for ...

Discussion Differential diagnoses included chip fracture of the patella, femur or tibia, or an avulsion fracture of a ligament insertion. Based on location and cranial-caudal instability, avulsion of the origin of the cranial cruciate ligament was considered most likely, with concurrent lateral collateral ligament sprain, and potential further intra-articular damage. Exploratory surgery of the ...

The development of an in vivo animal model of posterolateral knee instability is desired for devising effective interventions for this injury. Sequential sectioning of the popliteus tendon, lateral collateral ligament, and lateral capsule was done in cadaveric goat knees to create knee joint instability, followed by in vivo studies (Studies 1 and 2) of 7 and 3 months duration, respectively. In ...

We treated 43 acute tears of the calcaneofibular ligament by operation in 43 patients after subtalar arthrography. There were 22 men and 21 women with a mean age of 22.3 years (14 to 61). Anteroposterior (AP), lateral and oblique views were obtained with the foot in 45 degrees of internal rotation and the ankle in the neutral position. Any communication or leakage to the ankle, tendon sheaths, ...
