Several degenerative and inflammatory diseases may result
in pain and joint stiffness. Primary and secondary osteoarthritis,
rheumatoid arthritis (inflammation of synovial membrane), and
chondromalacia (softening of cartilage) are the most common
diseases of degeneration of synovial joints (Ref 1). These
diseases trigger the degenerations of the bones, joints, and other
tissues with excruciating pain. To achieve pain relief and
improve mobility, the degenerated natural surfaces are replaced
with advanced orthopedic biomaterials (Ref 2). Surgical
implantation is one of the solutions for restoring the function
of the impaired tissues (Ref 3).
