Statistics and Trends
Understanding the statistics and trends related to occupational knee pain is crucial in recognizing the impact it has on the workforce and society as a whole.
Occupational Injury Cases
In 2022, there were 547,980 cases involving sprains, strains, and tears that resulted in days away from work due to occupational injuries, according to the Bureau of Labor Statistics (BLS) [4]. It's important to note that knee injuries are among the common types of sprains, strains, and tears experienced by workers in various professions.
Additionally, injuries to the back were also prevalent, with 250,830 cases resulting in days away from work due to occupational injuries in the same year [4]. Falls, slips, and trips accounted for a significant portion of these cases, with 450,540 instances reported in 2022. These numbers highlight the need for preventive measures and strategies to reduce the occurrence of occupational knee injuries.
Impact on Workforce
The impact of knee injuries on the workforce is substantial. In 2022, private industry employers reported 2.8 million injury and illness cases, representing a 7.5% increase from the previous year. Of these cases, injuries accounted for 2.3 million, while illnesses accounted for 460,700 cases, showing a significant rise in illness cases.
Knee injuries can lead to missed workdays, decreased productivity, and potential long-term implications for employees. The consequences of occupational knee pain extend beyond the affected individuals, affecting workplace efficiency and overall productivity. Employers and employees alike should prioritize preventive measures and intervention strategies to mitigate the impact of knee injuries on the workforce.
To gain a comprehensive understanding of the prevalence and risk factors associated with occupational knee pain, it is important to explore the scope of knee injuries, high-risk professions, community study findings, and occupations with increased odds. This information will provide a deeper insight into the challenges faced by workers and the need for preventive strategies.
Associations with Osteoarthritis
Occupational knee pain not only affects individuals in terms of immediate discomfort but can also have long-term implications, particularly with regard to the development of osteoarthritis (OA). Understanding the link between occupational activities and knee OA is crucial for implementing preventive measures in high-risk professions.
Link to Knee OA
Multiple studies have shown that knee injuries, including those sustained in the workplace, are strong risk factors for the development of osteoarthritis [5]. Severe knee injuries, such as trans-articular fractures, meniscal tears requiring meniscectomy, or anterior cruciate ligament injuries, significantly increase the risk of developing OA and musculoskeletal symptoms. In fact, the prevalence of meniscal damage was found to be much higher among individuals with radiographic knee OA compared to those without OA [5].
Work-related activities that involve repetitive stress or trauma to the knee joint can contribute to the development of knee OA. The evidence suggests that certain occupational activities, such as squatting, kneeling, lifting, and engaging in physically demanding work, have a stronger association with knee OA. On the other hand, standing or walking alone does not appear to have a significant impact on the development of knee OA.
Heavy physical workloads and specific occupational activities have been identified as common risk factors for knee OA [7]. Occupations involving bending of the knee, kneeling or squatting, standing for long hours, walking long distances, regular stair climbing, heavy lifting, jumping, and exposure to vibration have been associated with an increased risk of knee OA. Workers in occupations such as construction, firefighting, agriculture, fisheries, forestry, and mining are particularly susceptible to knee OA, with male workers in manual labor occupations having higher odds of developing knee OA.
The synthesis of multiple studies has shown that there is an increased odds ratio of knee osteoarthritis in physically demanding jobs and occupational activities compared to sedentary occupations and low exposure groups [3]. These findings emphasize the importance of recognizing work-related loading effects on knee joints and implementing appropriate preventive measures.
By understanding the link between occupational activities and knee OA, employers and workers can take proactive steps to mitigate the risk. Implementing ergonomic practices, providing proper training and equipment, and promoting breaks and stretching exercises can all contribute to reducing the incidence of knee OA in high-risk occupations.

Economic Impact
When it comes to occupational knee pain, the economic impact is significant. Knee injuries can lead to various costs and burdens, both for individuals and the healthcare system.
Cost of Knee Injuries
A study conducted on workers' compensation claims found that the average total incurred costs per claim for knee injuries averaged $28,993 in 2007-2008. These costs include medical expenses, rehabilitation, and lost wages. The economic burden of knee injuries extends beyond the individual, affecting employers and insurance providers as well.
The cost of knee injuries can vary across different sectors. In 2010, the Transportation and Warehousing Sector had the highest knee injury rate, followed by the Utilities Sector and the Construction Sector. These costs not only impact the injured individuals but also contribute to the overall economic burden of knee pain.
Burden on Healthcare
Occupational knee pain also places a burden on the healthcare system. Knee osteoarthritis (OA) is a common consequence of occupational knee injuries. The economic burden associated with knee OA is substantial, costing the United States economy more than $60 billion per year. Direct expenditures for knee OA are allocated for medication, hospitalization, and other healthcare services [7].
The healthcare burden is further intensified when considering the risk factors associated with knee OA. Heavy physical workloads, bending of the knee, kneeling or squatting, and other repetitive movements contribute to the development of knee OA. Workers in manual labor occupations such as construction, firefighting, agriculture, fisheries, forestry, and mining are at increased risk for knee OA.
The economic burden of knee injuries and knee OA underscores the importance of prevention strategies and interventions in occupational settings. By implementing protective measures and recommendations, we can reduce the incidence of knee injuries and alleviate the associated economic strain. For more information on prevention strategies, refer to our article on prevention strategies.
The economic impact of occupational knee pain extends not only to individuals but also to healthcare systems and the overall economy. By understanding the costs and burdens associated with knee injuries, we can work towards implementing effective measures to reduce the prevalence and impact of occupational knee pain.
Prevention Strategies
When it comes to addressing occupational knee pain, implementing effective prevention strategies is crucial. By taking proactive measures, individuals can minimize the risk of knee injuries and promote overall knee health. Two key areas of focus for prevention strategies are protective measures and intervention recommendations.
