OA sufferers complain of stiffness on arising which lessens during daily activity. The affected joints may make a crunching noise when moving. This results when the roughed articular surfaces rub together. The course of OA is slow and irreversible, but in most cases, symptoms can be controlled with aspirin. Another treatment still under investigation involves injecting hyaluronic acid into the knee joint cavity.
Hyaluronic acid is a natural polysaccharide and lubricates and cushions the joint.
The acid's elastic nature enables it to bounce back to its original shape after being compressed. Hence, it protects the joint surface from further erosion. Athletes are the most common people to visit a doctor with some sort of knee problem. Runners, football players, baseball players, dancers, gymnasts, and marching band participants acquire knee injuries. The most common problems that plague athletes are torn meniscuses and tendinitis.
