Background
Hip disorders such as labral tears and femoroacetabular impingement (FAI) are recognized causes of pain in athletes. However, their prevalence in karate athletes remains understudied.
Methods
- An anonymous survey was distributed to karate athletes across a statewide martial arts organization (purple belt or higher).
- Questions addressed history of hip pain, diagnoses, belt level, competition status, and years of training.
- Statistical analysis was descriptive and exploratory.
Key Findings
- 30% of karate athletes reported experiencing hip pain.
- 12.5% were diagnosed with FAI; 18.8% with labral tears.
- Pain prevalence was higher in older and elite-level athletes, but not significantly associated with sex or years of experience.
- Karate practitioners reported lower overall rates of hip injury compared to athletes in other martial arts.
Conclusions
While hip pain is less frequent in karate than in other martial arts, it remains clinically relevant, particularly in aging and higher-level competitors.
What Does This Mean for Providers?
Orthopedic and sports medicine clinicians should maintain a high index of suspicion for FAI and labral pathology in karate athletes presenting with hip pain—especially among older or elite-level practitioners. Early imaging and referral may prevent progression and help maintain function in this athletic population.
