Muscle Anatomy Of The Knee

As the patella is both formed and resides within the quadriceps femoris tendon it provides a fulcrum to increase power of the knee extensor and serves as a stabilising structure that reduces frictional forces placed on femoral condyles. Both joint surfaces are padded with hyaline cartilage and enclosed inside a single joint cavity.

Guide To Knee Joint Anatomy

There are two main muscle groups around the knee.

Muscle anatomy of the knee. The tibiofemoral joint is the weight bearing joints of the knee joint. These muscles are the strongest and leanest in the entire body. These motions of the knee allow the body to perform such important movements as walking running kicking and jumping.

The quadriceps and the hamstrings. The knee joins the thigh bone femur to the shin bone tibia. The muscles of the knee include the quadriceps hamstrings and the muscles of the calf.

It allows the tendon of the quadriceps femoris knee extensor to be inserted directly over the knee increasing the efficiency of the muscle. The muscles around the knee help to keep the knee stable well aligned and moving. The smaller bone that runs alongside the tibia fibula and the kneecap patella are the other bones that make the knee joint.

Tendons connect the knee bones to the leg muscles that move the knee joint. These muscles work in groups to flex extend and stabilize the knee joint. The patellofemoral joint provides the tendon of the quadriceps femoris extensor of the knee to be inserted directly over the knee increasing the performance of the muscle.

The quadriceps comprise a four muscle group at the front of the thigh that performs the majority of the work to extend the knee. The quadriceps are a collection of 4 muscles on the front of the thigh and are responsible for straightening the knee by bringing a bent knee to a straightened position. The knee is one of the largest and most complex joints in the body.
