title: Autologous Blood Injection Works for Recalcitrant Lateral Epicondylitis.
abstract: BACKGROUND
  Recalcitrant lateral epicondylitis may be a disabling condition. Treatment of this condition is still controversial.
  
  
  OBJECTIVE
  In the present prospective study, we evaluated the long-term results of autologous blood injection for the treatment of recalcitrant lateral epicondylitis.
  
  
  METHODS
  Prospective clinical study.
  
  
  METHODS
  A total of 42 elbows of 40 consecutive patients (28 female, 12 male) were enrolled in this prospective study. Seven patients left the study (3 patients moved to another city, 1 patient died in the second week due to a heart condition, 1 patient quit the study because of the resolution of pain in the fourth week and 2 patients did not agree to the second injection). Thirteen patients were lost to third year follow-up. Therefore, a total of 21 elbows of 20 patients with 3 years of follow-up were included in this study. The mean age of the patients was 47.25 years (range, 20-68 years).
  
  
  RESULTS
  Visual analogue scale (VAS), Nirschl score and grip strength were significantly improved after injections when compared to before treatment. The best improvement in terms of grip strength, Nirschl score and VAS score was detected at the one year follow-up. The improvement in Nirschl and VAS score sustained until the third year.
  
  
  CONCLUSIONS
  We suggest that autologous blood injection for the treatment of recalcitrant lateral epicondylitis is an effective, safe and successful procedure in the long-term.
