Is blood group a risk factor in lateral epicondylitis?

Area of Science:

• Orthopedics
• Genetics
• Epidemiology

Background:

• Lateral epicondylitis, commonly known as tennis elbow, is a prevalent musculoskeletal disorder.
• Identifying risk factors is crucial for effective prevention and treatment strategies.
• The association between blood groups and lateral epicondylitis has not been previously investigated.

Purpose of the Study:

• To investigate the potential relationship between various risk factors and lateral epicondylitis.
• Specifically, to examine the correlation between blood group and the incidence of lateral epicondylitis.

Main Methods:

• A case-control study was conducted with 304 patients diagnosed with lateral epicondylitis and 304 healthy controls.
• Data collected included demographic information, lifestyle factors, occupational details, and blood type.
• Statistical analysis was performed to identify significant associations.

Main Results:

• Blood type O was found to be significantly more prevalent in the patient group compared to the control group (p<0.001).
• Several other potential risk factors were assessed, though the primary finding focused on blood type.

Conclusions:

• The study concludes that there is a significant association between blood type O and lateral epicondylitis.
• This finding suggests that blood group may be a previously unrecognized risk factor for developing lateral epicondylitis.
