Knee Injury Series Part 1: Knee Physiology

If you are a healthy, active individual, there is a high probability that at some point in your life you take a knee injury. If you play sports that require quick pivots such out of the box basketball, soccer, football, gymnastics, dance, tennis and skiing, if one is particularly at risk. While ankle injuries are slightly more prevalent, a knee injury is much of these is debilitating. 50% of sports knee injuries has to have medical attention and more than 400, 000 individuals have full-on Knee Replacement Surgery on an annual basis. Ask any sports once you start professional, and they knows that knee injuries are the commonest reason a player is sidelined about the entire season.

The knee certainly are a remarkable hinge joint between the femur (thigh bone), a right tibia (shin bone), fibula (long slender bone beside the tibia) and the patella (knee cap). It contains considerable stability thanks towards a network of ligaments, cartilage and muscles, but an injury can destabilize the patella, forcing an athlete to wear a patella stabilizer during training. The Q-angle, or perhaps the joint area between the tibia and femur, is some of the knee that is prone to overuse injury and joint disease.

Critical knee-related muscles the actual quadriceps and hamstrings. The quadriceps (quads) are considered the longest, leanest muscle group within your body. They connect to the most beneficial of the patella / kneecap now that the quads contract, however they pull laterally, extending the leg. Your quads are composed of four muscle groups, a right vastus medialis, the vastus lateralis, the vastus intermedius also , the rectus femoris. When individuals experience a knee injury in this area, they often lose significant strength from vastus medialis, located elizabeth lower inside potion of the quad. This muscle is critical to patellar stability, so an effective rehabilitation regimen need to pay specific attention to strengthening that area connect to restore knee tracking form. Conversely, the hamstring structure provides medial knee well-being and controls the knee flexion (i. e. bending your leg likewise knee. )

When it comes to knee injuries, tendons are incredibly at risk. The knee comes down to four key tendons which involves stability, specifically the MCL, LCL, ACL & PCL. The medial collateral ligament (MCL) is associated with the medial stabilizers which could be located deep within the knee inside knee. It connects contained in the lateral meniscus, so it's just not uncommon to have other wounds, such as a meniscus, ACL or cartilage tear since you injure the MCL. As a consequence, many MCL tears are effectively treated with an ACL brace. The anterior cruciate ligament (ACL) joins the femur to small lateral meniscus. Like since i MCL, an ACL injury can often be accompanied by other fascia or cartilage injuries. The lateral collateral ligament (LCL) runs on the side of the knee, connecting the femur for your tibula. This ligament is not attached to the lateral meniscus, making it less destined to be injured. Lastly, the posterior cruciate tendon (PCL) also connect the femur for your tibia, holding the knee entering place and preventing the tibia from moving posterior to the femur.
