Hip and Knee Arthroplasty Orthopedic Literature in Medical Journals-Is It Negatively Biased?

There was no evidence of publication bias of lower-extremity arthroplasty reports in the major medical journals (JAMA, NEJM, and Lancet). However, there were more published studies reporting on complications of lower-extremity arthroplasty. This may be due to systematic bias among journal editors in these journals, or due to low journal submission reporting noncomplications after arthroplasty intervention. We did not find the time period to be a factor in bias reporting of orthopedic literature in major medical journals. More work is needed to verify the results of this study.
