Nanotechnology, the science of manipulating materials at the molecular or atomic scale, is increasingly becoming a transformative force in medicine, particularly orthopedics. This field, which deals with the musculoskeletal system, including bones, joints, ligaments, tendons, and muscles, has long faced challenges in developing more effective treatments for injuries and degenerative conditions. Nanotechnology is emerging as a game-changer, offering new ways to enhance orthopedic implants, improve bone healing, and minimize surgery complications. The most significant application of nanotechnology in orthopedics is the improvement of implants used in joint replacement surgeries, such as those for knees, hips, and shoulders.
