While knee injury-related pain and functional limitations are common in the physically active, the impact on general health is not well documented. Further, it is not known how much these outcomes differ among individuals that did or did not have surgery following the knee injury, as well as compared to those without knee injury history. We examined differences in health-related quality of life (HRQoL) and general health among patients after knee surgery, knee injury that did not require surgery, and healthy controls. Knee surgery participants reported higher body mass index and lower SF-8 physical component scores than knee nonsurgery and control (p <.001 all comparisons) groups. Knee nonsurgery participants had lower SF-8 physical component scores (p =.01) than control participants. Patients after knee surgery report more adverse health effects than those with nonsurgically treated knee injuries.

Funding Information:
Using a cross-sectional study design and as part of a larger study, an online survey regarding knee injury and/or surgery history, quality of life, and health outcomes was administered to a random sample of 20,000 adults, ages 18–80, living in the United States through the ResearchMatch© national registry. ResearchMatch.com, a national health registry in which volunteers consent to be contacted regarding health studies for which they may be eligible, was created by several academic institutions and is supported by the U.S. National Institutes of Health as part of the Clinical and Translational Science Award (CTSA) program. Individuals interested in the study were emailed a link to the survey (Research Suite, Qualtrics, LLC, Provo, UT) between April 2015 and March 2016. To remove the confounding effect that previous ankle injuries may have on HRQoL, anyone who reported a history of ankle injury was excluded from the current study. The institutional review board at the University of Kentucky approved this study.
