Many knee problems are a result of the aging process and continual wear and stress on the knee joint (such as, arthritis). Other knee problems are a result of an injury or a sudden movement that strains the knee. Common knee problems include the following:
- Sprained or strained ligament. A sprained or strained knee ligament or muscle is usually caused by a blow to the knee or a sudden twist of the knee. Symptoms often include pain, swelling, and difficulty in walking.
- Torn Cartilage Trauma to the knee can tear the menisci (pads of connective tissue that act as shock absorbers and also enhance stability). Cartilage tears can often occur with sprains. Treatment may involve wearing a brace during an activity to protect the knee from further injury. Surgery may be needed to repair the tear.
- Tendonitis. Inflammation of the tendons may result from overuse of a tendon during certain activities such as running, jumping, or cycling. Tendonitis of the patellar tendon is called jumper’s knee. This often occurs with sports, such as basketball, where the force of hitting the ground after a jump strains the tendon.
- Arthritis. Osteoarthritis is the most common type of arthritis that affects the knee. Osteoarthritis is a degenerative process where the cartilage in the joint gradually wears away. It often affects middle-age and older people. Osteoarthritis may be caused by excess stress on the joint such as repeated injury or being overweight. Rheumatoid arthritis can also affect the knees by causing the joint to become inflamed and by destroying the knee cartilage. Rheumatoid arthritis often affects persons at an earlier age than osteoarthritis.
By gently separating the joint space between the bottom of the femur (thigh bone) and the top of the tibia (shin bone) we can create a vacuum effect inside the knee joint which brings more nutrient-rich ﬂuid to the area.
This also stretches the tendons, ligaments, and other soft tissue around the joint. This combined effect helps to re-establish some of the natural joint space and cushioning in the knee.
