An August 2010 study by Kazremi et al performed a single blinded randomized clinical trial comparing autologous blood injections to corticosteroid injection in 60 individuals with lateral elbow tendinopathy during the past year. [15] Bracing, physical therapy, or anti-inflammatory medications were not allowed during the duration of the study.

Outcomes were measurement of VAS pain scale, DASH questionnaire, modified Nirschl pain scores, maximum grip strength, and pain pressure threshold. Short-term follow-up was ascertained at 4- and 8-week intervals. Corticosteroid injections demonstrated improvements at 4 weeks in all outcome scores except pain pressure threshold. There was no significant improvement from 4-8 weeks in the steroid group for any of the outcomes except a decrease in limb pain and a worsening of grip strength. The autologous blood group demonstrated statistically significant improvements in all outcomes measured at 4 and 8 weeks. Autologous blood injections demonstrated superiority to corticosteroid injections at 4 and 8 weeks in all parameters measured. [15]
