In a review of medical information regarding a single cancer topic, the authors found abundant nonpeer‐reviewed material and a 6% rate of factual inaccuracies. Therefore the authors recommend that physicians maintain an open mind regarding searches done by patients and questions raised by those searches, and suggest that physicians take an active role in identifying or creating patient information Web sites and in educating the lay public regarding variations in the quality of information and the contribution of the peer review process.

The aim of this prospective multicentre study was to report the patient satisfaction after total knee replacement (TKR), undertaken with the aid of intra-operative sensors, and to compare these results with previous studies. A total of 135 patients undergoing TKR were included in the study. The soft-tissue balance of each TKR was quantified intra-operatively by the sensor, and 18 (13%) were found to be unbalanced. A total of 113 patients (96.7%) in the balanced group and 15 (82.1%) in the unbalanced group were satisfied or very satisfied one year post-operatively (p = 0.043). A review of the literature identified no previous study with a mean level of satisfaction that was greater than the reported level of satisfaction of the balanced TKR group in this study. Ensuring soft-tissue balance by using intra-operative sensors during TKR may improve satisfaction.
