Posterior cruciate ligament recruitment affects antero-posterior translation during flexion gap distraction in total knee replacement
BACKGROUND AND PURPOSE Because of the oblique orientation of the posterior cruciate ligament (PCL), flexion gap distraction could lead to anterior movement of the tibia, which would influence the tibiofemoral contact point. This would affect the kinematics of the TKR. We assessed the flexion gap parameters when the knee is distracted during implantation of a PCL-retaining TKR. Furthermore, the ...
متن کاملThe posterior cruciate ligament during flexion of the normal knee.
The posterior cruciate ligament (PCL) was imaged by MRI throughout flexion in neutral tibial rotation in six cadaver knees, which were also dissected, and in 20 unloaded and 13 loaded living (squatting) knees. The appearance of the ligament was the same in all three groups. In extension the ligament is curved concave-forwards. It is straight, fully out-to-length and approaching vertical from 60...
متن کاملPosterior Cruciate Ligament: Current Concepts Review
The posterior cruciate ligament (PCL) is the largest and strongest ligament in the human knee, and the primary posteriorstabilizer. Recent anatomy and biomechanical studies have provided an improved understanding of PCL function. PCLinjuries are typically combined with other ligamentous, meniscal and chondral injuries. Stress radiography has becomean important and validated objective measure in...
متن کاملThe Posterior Cruciate Ligament
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...
متن کاملAnatomy of the posterior cruciate ligament.
The purpose of the study was to explain the architecture of the posterior cruciate ligament because the views on its structure presented in the literature are inconsistent - from those considering it as indivisible to those presenting it as a multifascicular structure. Twenty formalin-fixed ligaments from human knee joints were tested using the preparation technique. All posterior cruciate liga...
