Double-Blind Randomized Controlled Trial: Injection of Autologous Blood in the Treatment of XXXX -A Pilot Study.

@entity1 @entity924
OBJECTIVE: To assess the efficacy of autologous blood injections (ABIs) against saline in @entity1 with @entity924 (PT). DESIGN: Double-blind randomized controlled study. SETTING: Homerton Hospital Sports Medicine department. @entity1 : Those with a diagnosis of @entity924 were recruited between March 2010 and March 2012. INTERVENTIONS: Using 2 practitioners, @entity1 were randomized to either receive ABIs or saline injections. MAIN OUTCOME MEASURES: All @entity1 completed the Short-Form McGill Pain Questionnaire (MPQ), a visual analog scale (VAS), and a Victoria Institute of Sport Assessment for Patella @entity924 scale over a 12-month period. RESULTS: Twenty-two @entity1 completed the final review at 12 months and were included in the study. Subjects ranged in age from 22 and 61 years and were randomized to 11 in each ABI and saline groups. Autologous blood injection group had a mean duration of symptoms of 16.7 months, whereas that of the saline group was 19.2 months. The saline group mean VAS score was reduced from 7.9 to 4.5 at 1 month (P = 0.003) and 3.3 (P = 0.005) at 1 year. With ABI, the score was reduced from 7.5 to 4.5 (P = 0.005) at 1 month and 3.1 (P = 0.003) at 1 year. Victoria Institute of Sport Assessment for Patella @entity924 , MPQ, and VAS scores improved significantly in both groups. CONCLUSIONS: This study demonstrated that both the ABI and saline groups experienced a significant improvement in symptoms. However, when the results were compared, there was no statistical difference between the 2 groups. CLINICAL RELEVANCE: This research showed that tendon fenestration is an alternative cost-effective treatment for recalcitrant PT.
