Enthusiasm for bone ingrowth devices is running high. New technology and procedures are greatly needed by practicing orthopedic surgeons. Some pressure for new technology comes from the patients. This atmosphere creates the major danger of overreacting to this unproved but attractive approach to joint replacement. Considerably more basic research needs to be done on the interface and the optimal stress transmission at this interface. The long-term effects of ion release and debris must be determined. Prospective randomized clinical trials would be helpful but probably will not be initiated on a widespread basis because neither surgeons nor patients like to have surgical treatment assigned randomly. Some form of objective assessment, possibly by individuals not involved in the design of the devices, would seem essential for precisely defining the efficacy of biologic fixation in joint replacement surgery. Certainly, the early experience is encouraging, but caution and discriminating judgement must continue to be exercised when considering joint replacement with uncemented devices.
