High-Density Hyaluronic Acid Injection in Joint
Osteoarthritis is the most common form of joint disease. Lesion mainly occurs to the contact surface of two bones where the joint cartilage is injured and damaged, causing rugged joint surface, decreased joint space, and bone spur. The most common symptoms are joint pain, stiffness, swelling, deformation, and noises during joint movement. 

Hyaluronic acid has been used in attempts to treat osteoarthritis of the knee via injecting it into the degenerated joint. It has great moisture retention, and its viscoelasticity and lubricity are compatible to joint cartilage. Covering hyaluronic acid on the surface of cartilage protects the cartilage from wearing out and degenerating. It also reduces inflammation and articular contracture, and increases joint movement ability, effectively treating mild and moderate degrees of osteoarthritis.
