G Potential positive effects of ultrasound-guided tendon fenestration. G It is unknown which factors influence the outcome of the procedure G Do some tendons have better outcomes compared to others? G Does increased vascularity, echogenicity, or size of the tendon abnormality at ultrasound influence results? G Chronicity: It is unknown whether chronicity of the symptoms, prior treatments, and patient variables such as age or smoking affects outcome. G Technique: it is unknown whether needle choice or number of needle passes through the tendon has an effect. Lastly, because other percutaneous ultrasound-guided tendon injections such as hyperosmolar dextrose, autologous whole blood, and PRP also involve tendon fenestration during the procedure, does tendon fenestration alone produce similar results compared with these tendon injections?
