The anterior cruciate ligament (ACL) is one of a pair of cruciate ligaments (the other being the posterior cruciate ligament) in the human knee.The two ligaments are called "cruciform" ligaments, as they are arranged in a crossed formation.
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.

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 [2] then stretches, at a posterior and lateral angle, toward the posterior of the tibia just below its articular surface.
Rates of re-rupture among college athletes were highest in male football players with 15 per 10,000, followed by female gymnasts with 8 per 10,000 and female soccer players with 5.2 per 10,000. [66] High school athletes are at increased risk for ACL tears when compared to non-athletes.
[4] [5] Around $500 million health care dollar will come from ACL injuries. ACL injuries can be categorized into groups- contact and non-contact based on the nature of the injury [6] Contact injuries occur when a person or object come into contact with the knee causing the ligament to tear. However, non-contact tears typically occur during the ...
Acute injury to the medial meniscus frequently accompanies an injury to the ACL (anterior cruciate ligament) or MCL (medial collateral ligament). A person occasionally injures the medial meniscus without harming the ligaments. Healing of the medial meniscus is generally not possible unless the patient is very young, usually <15 years old.
It is about 4.5 cm long in adults (range from 3 to 6 cm). [2] The medial and lateral portions of the quadriceps tendon pass down on either side of the patella to be inserted into the upper extremity of the tibia on either side of the tuberosity; these portions merge into the capsule, as stated above, forming the medial and lateral patellar ...
The next step of identifying the POL femoral attachment is done by locating the gastrocnemius tubercle (2.6 mm distal and 3.1 mm anterior to the medial gastrocnemius tendon attachment on the femur). If the posteromedial capsule is not intact, the POL attachment site is located 7.7 mm distal and 2.9 mm anterior to the gastrocnemius tubercle.
