A study by Connnell et al in 2005 looked at ultrasound-guided autologous blood injections as a treatment for 35 individuals with lateral epicondylitis confirmed on MRI. These patients had symptoms for a median of almost 14 months and conservative therapy had not been successful. Outcomes were measured as reduction in VAS and Nirschl pain scores at 4 weeks and 6 months. No formal physical therapy or home exercise program was recommended. Autologous blood injections demonstrated significant improvements in VAS and Nirschl pain measurements at 4 weeks and at 6 months. Autologous blood injections also demonstrated statistical improvements in tendon thickness, interstitial cleft formation, echoic foci, hyperechoic change, and neovascularity. [11]
