Research recommendation(s) from an individual piece of guidance Guidance: Autologous blood injection for tendinopathy Date issued: 23 January 2013 Research recommendations coming out of this guidance NICE encourages further research comparing autologous blood injections (with or without techniques to produce platelet-rich plasma) against established nonsurgical methods for managing tendinopathy. Trials should clearly describe patient selection (including the site of tendinopathy, duration of symptoms and any prior treatments) and document whether a 'dry needling' technique is used. Outcomes should include specific measures of pain, quality of life and function, and whether subsequent surgical intervention is needed.
