Anterior cruciate ligament surgery is a complex operation that requires expertise in the field of orthopedic and sports medicine. Many factors should be considered when discussing surgery, including the athlete's level of competition, age, previous knee injury, other injuries sustained, leg alignment, and graft choice.
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 .
On the tibia, the anterior reflection and attachment of the synovial membrane is located near the cartilage. [2] Anteriorly, the infrapatellar fat pad is inserted below the patella and between the two membranes. It extends from the lower margin of the patella above, to the infrapatellar synovial fold below.
Injuries to the PLC often occur in combination with other ligamentous injuries to the knee; most commonly the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL). [2] As with any injury, an understanding of the anatomy and functional interactions of the posterolateral corner is important to diagnosing and treating the injury.
In front of and behind the intercondyloid eminence are rough depressions for the attachment of the anterior and posterior cruciate ligaments and the menisci. Two tubercles emerge from the eminence: The medial intercondylar tubercle is a protrusion on the medial condyle. The lateral intercondylar tubercle is a protrusion on the lateral condyle.
The anterior cruciate ligament (ACL) of the knee is commonly injured. There is insufficient re-vascularization of the ligament after complete rupture, which limits its ability to heal and necessitates reconstruction surgery. Within the last 20 years, new types of synthetic ligaments have been developed.
However, the anterior cruciate ligament is the most important contributor to rotatory knee stability. It is uncertain if an isolated anterolateral ligament injury with an intact anterior cruciate ligament injury leads to knee instability. This topic is being hotly debated and researched.
An anterior cruciate ligament injury occurs when the anterior cruciate ligament (ACL) is either stretched, partially torn, or completely torn. [1] The most common injury is a complete tear. [ 1 ] Symptoms include pain, an audible cracking sound during injury, instability of the knee, and joint swelling . [ 1 ]
