Summary: The objective of this study is to evaluate how an ultrasound-guided percutaneous procedure, TENEX, can help people with chronic hip pain resulting from a condition called Greater Trochanteric Pain Syndrome (GTPS) and to characterize the efficacy of percutaneous tenotomy (PUT) using TENEX®, a device used for the treatment of various tendinopathies. In this study an ultrasound (US) is performed to g...
