Research Study to Compare the Addition of Topaz Micro Debridement to the Standard of Care Surgery
A Randomised, Controlled, Double-blind Clinical Investigation on the Efficacy and Safety of Radiofrequency Micro Debridement, Topaz, in Recalcitrant Greater Trochanteric Pain Syndrome (GTPS) vs. Standard of Care

Compare the surgical use of Topaz with the Standard Of Care in the treatment of Greater Trochanteric Pain Syndrome (a type of hip pain). The hypothesis is that there is a difference between the two treatment groups.
