Abstract: Purpose To evaluate the epidemiology of hamstring tendon injuries in the United States from 2015 to 2024 and to project incidence trends through 2030. Methods Patients diagnosed with hamstring strains between 2015 and 2024 were identified using International Classification of Diseases, 10th Revision code S76.31. Data were collected using the TriNetX US Collaborative Research Platform, which includes over 120 million deidentified patient records. Incidence proportion was calculated annually. Demographic substratification by age and sex was performed, and linear regression was used to project incidence through 2030. Results A total of 118,197 patients with hamstring injuries were identified, with a mean age of 48.7 years; 49% were female. In 2024, hamstring injury incidence was 42.79 per 100,000 (95% confidence interval, 42.01‐43.98), a significant increase from 11.61 per 100,000 (95% confidence interval, 11.28‐11.94) in 2015 ( P < .001). A bimodal distribution was noted, with the highest total number of injuries in adults aged 60 to 64 years and the highest incidence proportion in those aged 15 to 19 years. Under age 35 years, males had higher injury rates, while over age 35 years, females had higher rates. Projections estimate that incidence will rise to 56.2 per 100,000 by 2030 ( R 2 = 0.83), reflecting a 6.7% average annual increase through 2030. Conclusions There is a rising burden of hamstring injuries in the general population, with the highest incidence among older adults and young people. Projections based on current trends estimate that the annual incidence of these injuries will continue to rise. Level of Evidence Level IV, descriptive epidemiologic study.
