The treatment of hyaline cartilage injury and degeneration is a challenge for orthopaedic surgeons. Hyaline cartilage pathology accounts for a large portion of office practice and operative procedures, but treatment remains unpredictable. The actual regeneration of hyaline cartilage is probably beyond current reach. Scientists have long wrestled with how to aid those who suffer cartilage damage and loss. One popular way is to inject an artificial gel that can imitate cartilage’s natural ability to act as the body’s shock absorber. But that solution is temporary, requiring follow-up injections.Now Brown University nanotechnology specialist Thomas Webster has found a way to regenerate cartilage naturally by creating a synthetic surface that attracts cartilage-forming cells. These cells are then coaxed to multiply through electrical pulses. carbon nanotubes, which are molecular-scale tubes of graphitic carbon that are among the stiffest and strongest fibers known and are great conductors of electrons have unique surface properties and closely resembles the contours of natural tissue, so cartilage cells see it as a natural environment to colonize. The cartilage cells grow more densely by the application of electrical pulses which helps calcium ions enter a cell which is known to play an integral role in growing cartilage.
