Knee injury reports are trending upward
OSHA has recorded 1,625 severe knee injuries over the last decade, with fractures accounting for 43.7 percent of these incidents. These cases represent only the most serious injuries requiring hospitalization, meaning the total impact on the workforce is likely much higher.
The knee is a critical joint for stability and weight-bearing, making any injury to this area a direct threat to a worker's ability to perform physical tasks. Even minor tears or fractures can lead to permanent mobility limitations, impacting a worker's long-term earning capacity and daily quality of life.
The 17.4 percent increase in knee injury reports over the last ten years highlights a persistent failure in workplace safety protocols. Falls on the same level remain the primary driver, accounting for 48.7 percent of all reported incidents, suggesting that basic housekeeping and surface maintenance are frequently ignored.
Manufacturing and health care sectors lead the injury counts, representing 17.6 percent and 17.3 percent of cases respectively. These environments often involve high-paced movement across constructed surfaces where slip and trip hazards are common but remain insufficiently addressed by management.
Top causes based on OSHA incident reports
Most knee injuries occur when workers encounter hazardous walking surfaces or fall from elevated positions. Nearly half of all reported knee injuries result from falls on the same level, often caused by spills, debris, or uneven flooring that employers fail to clear or mark.
| Cause | Incidents | |
|---|---|---|
| 1 | Fall on same level | 766 |
| 2 | Other fall to lower level | 336 |
| 3 | Struck by falling object | 71 |
| 4 | Struck by propelled object or substance | 64 |
| 5 | Injured by object handled by person | 33 |
| 6 | Slip, trip, stumble on same level— without fall | 24 |
| 7 | Pedestrian struck by vehicle in nonroadway area | 24 |
| 8 | Nonroadway collision with object other than vehicle | 24 |
Employers are legally required to maintain safe walking and working surfaces under 29 CFR 1910.22. When a worker suffers a knee injury due to a slip or trip, it often indicates a failure to comply with these standards, providing a clear basis for evaluating potential legal claims.
Where these injuries occur most frequently
Manufacturing and health care facilities account for over one-third of all severe knee injuries. In these settings, workers are frequently required to navigate crowded floors while carrying heavy loads or assisting patients, which significantly increases the risk of a fall.
Under 29 CFR 1910.22, employers must ensure that all places of employment are kept clean, orderly, and in a sanitary condition. Furthermore, 29 CFR 1910.25 mandates specific requirements for stairways to prevent falls, which are a major source of knee trauma in industrial and commercial settings.
From actual OSHA investigation files
Reported incidents reveal a recurring pattern of workers suffering severe knee fractures after slipping on common workplace hazards like mud, spilled liquids, or loose debris. These narratives frequently involve employees performing routine tasks, such as carrying supplies or moving between rooms, only to have their mobility permanently compromised by preventable floor conditions.
"An employee was picking up litter on the perimeter of the complex. He was outside the facility grounds by the railroad tracks when he tripped in the rocks and fell, striking his head and knees. The employee sustained a fractured knee."
"An employee entered a resident's room at 8:13 p.m., and was passing medication to the patient when they slipped and fell to the floor. The employee was hospitalized with a knee injury that required surgery."
"An employee was returning a cleaned tea dispenser to the kitchen when they slipped on tea and fell on the floor. The employee sustained injury to their right knee."
