Creating knee workouts is so important as it is one of the joints in the body that is most frequently injured is the knee joint. Because there are so many different muscles and ligaments running through the knee joint, there is an increased chance that if it is not tracking properly you will experience inflammation, potential bone grinding and pain.
Developing those knee workouts will help as Usually injuries to the knee occur most in contact sports because even though it is held strongly together by all these ligaments, its articular surfaces do not offer any help in terms of stability. This means that there is no socket for the knee to sit in, so to speak, so anytime there is a horizontal force applied it is really quite easy for the knee to move in a direction it is not supposed to go.
The worst types of injuries will be lateral blows, which will usually result in a tear in the tibial collateral ligament and the medial meniscus that attaches to it. The anterior cruciate ligament (ACL) may also become affected which plays a predominant role in knee movement.
ACL injuries are some of the most common ones seen and usually occur most frequently when someone is running and then all of a sudden stops and changes direction. As this ligament does not heal that well on its own, usually surgery needs to be performed to insure the injury is treated properly. The surgery is normally done by applying a graft from either the patellar ligament, the Achilles tendon or else the semitendinosus tendon.
So be sure to perform some proper exercises for the muscles surrounding this joint in your program. By strengthening them you can reduce the risk of the cap moving out of alignment and resulting in injury.
