Nowell et al. set out to understand patient decision making in total knee arthroplasty as there is limited research in this area. Focus groups were formed within an online community and identified decisions about total knee arthroplasty beyond the decision to have the surgery itself. An online survey was used to determine relative importance of five major decisions. Patients reported that they felt they did not have enough information to make important decisions of surgeon, device type, surgical approach, facility, or timing for their surgery.
