The PCL is located within the knee joint where it stabilizes the articulating bones, particularly the femur and the tibia, during movement.It originates from the lateral edge of the medial femoral condyle and the roof of the intercondyle notch [5] then stretches, at a posterior and lateral angle, toward the posterior of the tibia just below its articular surface.
The posterior cruciate ligament (PCL) is important to the stability of the knee by preventing posterior subluxation of the tibia, reducing shear stress, increasing flexion and lever arm of the extensor mechanism by inducing femoral rollback upon flexion, and thus minimizing polyethylene abrasion through reducing stress applied to the articular ...
The posterior cruciate ligament (PCL) is a ligament in each knee of humans and various other animals. It works as a counterpart to the anterior cruciate ligament (ACL). It connects the posterior intercondylar area of the tibia to the medial condyle of the femur. This configuration allows the PCL to resist forces pushing the tibia posteriorly ...
Relative to the femur, the ACL keeps the tibia from slipping forward and the PCL keeps the tibia from slipping backward. Another structure of this type in human anatomy is the cruciate ligament of the dens of the atlas vertebra, also called "cruciform ligament of the atlas", a ligament in the neck forming part of the atlanto-axial joint .
Initial physical therapy consists of range of motion (ROM) exercises, often with the guidance of a physical therapist. Range of motion exercises are used to regain the flexibility of the ligament, prevent or break down scar tissue from forming and reduce loss of muscle tone. Range of motion exercise examples include: quadriceps contractions and ...
The goal of reconstruction surgery is to prevent instability and restore the function of the torn ligament, creating a stable knee. There are certain factors that the patient must consider when deciding for or against surgery. An important post-surgical treatment of unhappy triad is Physical Therapy (PT).
ACL injury used to be a career-ending injury for competitive athletes; however, in recent years ACL reconstruction surgery followed by physical therapy has allowed many athletes to return to their pre-injury level of performance. [62] Long term complications of ACL injury include early onset arthritis of the knee and/or re-tearing the ligament.
The preparation can be done while the other steps are being completed by another surgeon or physician's assistant. The semitendinosus tendon can be harvested using a hamstring stripper for use as the reconstruction autograft. [26] The autograft is sectioned into a 16-cm length for the sMCL reconstruction and 12-cm length for the POL reconstruction.
