Workplace-based prevention and management of knee pain: a systematic review.

Abstract

Knee pain is highly prevalent and disabling among the general and working population. This systematic review explored the effectiveness of workplace-based interventions on knee pain among workers. A PICO-guided systematic search was performed in PubMed and Web of Science Core Collection for articles published from 2003 until January 2023. Eligible articles included randomized and non-randomized controlled trials assessing the effect of workplace-based interventions on knee pain among currently employed adult workers. The quality assessment and evidence synthesis adhered to the systematic review approach, which the Institute for Work & Health developed, and was focused on developing practical recommendations for stakeholders. Of the 13 identified studies, 11 medium- and high-quality studies were entered into the evidence synthesis. Importantly, none of the included studies specifically aimed at reducing of knee pain. Still, among the included studies, a strong level of evidence suggested no benefit of workplace-based physical exercise/activity intervention on knee pain. The level of evidence was deemed too uncertain to guide current policy/practices for ergonomic and multifaceted interventions. No intervention types were associated with negative effects on knee pain. The current evidence-base pertaining to workplace-based prevention and management of knee pain is insufficient to guide effective preventive workplace practice or policy development. Considering the global prevalence and health impact of knee pain, development and implementation of effective workplace interventions aimed at prevention and management of knee pain is needed.
