Abstract
Background
In martial artists, the hip joint is used repeatedly for kicking, jumping, and twisting. However, there is a paucity of knowledge regarding the prevalence of hip injuries in this population.
Purpose
The purpose of this study was to investigate the prevalence of hip labral tears and femoroacetabular impingement (FAI) in karate athletes using a statewide online survey.
Study Design: Descriptive epidemiology study
Methods
An anonymous electronic survey was distributed via Qualtrics to all members of a registered statewide karate organization who were a purple belt or higher. Basic demographic information was collected as well as belt level, competitive level, and information regarding hip pain and treatment for hip pain. Microsoft Excel was used to store and analyze data.
Results
Of 180 respondents, 123 (69.5%) never had hip pain when practicing karate, and 54 (30.5%) have had hip pain at some point in their career. Three subjects did not provide an answer. Furthermore, of the symptomatic individuals, 52 reported the location of their hip pain, while 2 subjects did not. Out of the symptomatic individuals (54), 32 had formal diagnoses by a medical professional. 44 (12.5%) were diagnosed with FAI of the hip, 6 (18.8%) diagnosed with a hip labral tear, 3 (9.4%) diagnosed with hip bursitis, 3 (9.4%) diagnosed with hip arthritis, and 16 (50%) had other diagnoses. The remaining 22 participants have not received a formal diagnosis by a medical professional.
Conclusion
In this survey of karatekas, the prevalence of hip injuries identified was comparable to athletes of other sports within the current literature. No differences in the percentage of injuries were found between gender and years practiced, however, significant differences were found between elite status and age group. In conclusion, when evaluating hip pain in the karate population, orthopedic surgeons should maintain an index of suspicion for FAI and hip labral tears.
