Bilateral total knee arthroplasties: a call for practice guidelines.

The authors reflect on the debate over the risks and benefits of same-day bilateral total knee arthroplasty (BTKA). They argue that the subject is of greater interest by physicians because the number of total joint arthroplasties in general has been rising dramatically. They suggest the need for hospitals and physicians to consider using conservative patient selection criteria to mitigate the increased risk for complication associated with same-day BTKA.
