Answer

Autologous blood injections are thought to initiate an inflammatory process and promote improved healing of degenerative tissue via the relatively atraumatic injection itself as well as providing necessary cellular and humoral mediators to induce a healing cascade. [25] Edwards and Calandruccio studied 28 people in whom conservative therapy had failed to resolve symptoms from their lateral epicondylitis. [26] They were given a cock-up wrist splint and told to avoid any other bracing or physical therapy for 3 weeks. A home exercise program was initiated at week 3. The study demonstrated 22 (79%) of 28 of the patients had a reduction in Nirschl pain scores over 9.5 months after autologous blood injection therapy. [26] Most often, this occurred after only one injection. However, this study is limited as it lacked a control group. [10]
