The Biology of Knee Ligaments

By Edited Aug 9, 2016 0 0

An Overview of Knee Ligaments

Anatomy and Physiology of the Knee Ligaments

The location of knee ligaments is around the knee joint and they function to offer stability of the joints which prevents excessive movement of the two bones constituting the joint. Ligaments also play a role in protecting the articlular capsule. They are fiber- like structures which are found running from one bone to the other and joining them together.

The Intracapsular Segment of Knee Ligaments

Collateral Knee Ligaments

Cruciate ligaments which occur in pairs help to stabilize the knee. The anterior segment of these ligaments extends starting from the lateral condyle femur and terminates at the anterior region of the intercondylar area. They function to prevent the pushing of tibia very far to the anterior side taking into consideration the position of femur. Posterior segment of cruciate ligaments extends starting from medial condyle of the femur to the posterior region of intercondylar area. The transverse segment extends between the lateral meniscus to the medial meniscus. Meniscofemoral ligaments which are divided into posterior and anterior segments extend from the lateral meniscus at the horn region up to the medial femoral condyle. Meniscotibial ligaments originate from the edges of menisci and extend to get to the tibial plateaus.

The Extracapsular Segment of Knee Ligaments

Knee Ligaments Functions

The patellar ligaments function to join the patella to tibia. They are sufficiently strong and offer the mechanical leverage of the patella. They also have a function as a cap for condyles found on the femur. Medial collateral ligaments extend starting at medial epicondyle of femur up to medial tibial condyle. The oblique popliteal and actuate popliteal ligaments are found on the dorsal side of the knee.

Some Injuries of Knee Ligaments

Knee pain relief

The medial collateral ligaments are more prone to injuries than the lateral segment of these ligaments. A blow to the outer side of the knee will cause these injuries. This will make the ligaments to stretch causing them to tear towards the inner side. There are a number of symptoms that will indicate an injured ligament. There occurs a feeling of buckle on the sides of the knee when injuries occur. Recruitment of cytokines to the injured areas cause inflammatory responses which cause swelling that is mostly associated with heat and pain. This might take some time to develop after the specific injuries of ligaments have occurred. Minor sprains of the ligaments will naturally heal and will take a short period of time to revert back to their normal state.

Treat Knee Ligament Problem

The diagnosis for these problems will involve application of pressure to the side of the knee in order to assess the degree of pain and the level of the destroyed ligament. RICE procedures are used in first aid techniques to help reduce pain to the victim and prevent chances of swelling from occurring. This will involve resting the individual in a comfortable position followed by ice application at the site of injury. Compression of the suffering region is also done using soft massage techniques. Elevation of the injured part to a height above the heart is then carried out. Loss of function of knee ligaments will greatly affect the locomotion function of the knee.
