The Knee is the joint between your upper and lower leg. The Femur (Thigh Bone) sits on the Tibia (Shin Bone) and is covered by the Patella (Kneecap). In between the bones is a strong cartilage called the Meniscus that acts like a shock absorber. The knee joint is where the muscle tendons of your upper and lower leg muscles attach.
You need healthy knee joints if you want to walk or run correctly or just about anything you do standing. Proper mobility requires proper alignment and function of the knee joint, a healthy meniscus and strong healthy muscles.
Arthritis of the knees, Osteo Arthritis (OA) degeneration of the bones, and Rheumatoid Arthritis (RA)degeneration and inflammation of the cartilage, occur as the result of chronic knee joint dysfunction or autoimmune issues respectively. Injury to the meniscus is also a very common knee joint problem.
Knee OA is very common among heavy or obese people. Your knees are not designed to carry too much weight, only a normal healthy weight.
If you are playing sports, be sure you strengthen your upper and lower leg muscles to be sure your knee joint is strong and stable. Use caution when getting in and out of your car, do not twist your knee joint.
Be sure to maintain a proper body weight. Warm up your knees before playing sports, stretch the leg muscles.
