In a study published by BMJ, Nov 2011, a comparison was made among traditional metal-on-polyethylene hip implants versus newer metal-on-metal and ceramic-on-ceramic implants. The results showed that revision rates were lower with the traditional implants and there were no advantages to the newer types.

COMMENT: It is commonly assumed that newer is better and the latest technology has advantages over previous technology. This study disproves that. In fact, the newer implants are more expensive and thus are unnecessary, simply increasing the costs of health care. Unfortunately, they will still be used due to incentives from the company to orthopedic doctors. be sure to ask your doctor what type of implant he will use. Of course, be sure to undergo cold laser treatment first....it may prevent the need for hip replacement in the first place and is significantly cheaper.
