The M2a-Taper(TM) People facing joint replacement of the hip often wonder if they will be able to resume a more active lifestyle after surgery. An additional concern is whether their new hip components will be able to withstand the excess stress of a more active lifestyle. because hip implants are subject to wear over time, it was necessary to develop implants that may withstand the higher demands of more active lifestyles. This led to the development of the M2a-Taper™ metal-on-metal implant, which is designed to provide long-term resistance to wear. Benefits of the M2a-Taper™ Metal is hard. As it moves against other material it creates friction, which wears down the material against which it moves. The more active a person is, the more movement and friction is placed against the hip implants. Since metal resists wear better, the M2a-Taper™ is better able to resist wear. This means there is a strong possibility that it can outlast traditional implants. Dr. Schmaltz and his team will consider your activities level, health, and age before recommending metal-on-metal implants.
