A technology assessment study design.
Randomized controlled trials of drug therapies are now required before the licensing and use of almost all medications. Other health care technologies should be similarly evaluated. The area of competing technologies requires more research, and cemented and noncemented hip prostheses have recently been identified as an important example of such a technology. Although trials such as ours require considerable care in their planning and execution, they can be conducted on a busy clinical teaching ward without adversely affecting the quality and quantity of clinical care.
