The goal of this study is to determine if a newer tenotomy technique utilizing an ultrasound needle is more effective than the traditional tenotomy technique utilizing a simple hypodermic needle for gluteal tendinosis. The main questions it aims to answer are:
1. Is pain from the gluteal tendinosis improved with either technique, and, if so, is there a difference in the improvement between techniques?
2. Is there an improvement in function for gluteal tendinosis, and, if so, is there a difference between techniques?
Description
Study Design This study is designed as a single-blinded, randomized control trial with two parallel arms comparing PNT vs PUT device for the treatment of gluteal (medius and minimus) tendinosis with analysis of pain, physical function, activities of daily living (ADLs) and overall health over four months. Participants will be randomly assigned (1:1) to receive PNT or PUT at one academic medical center. Each participant will be assigned a patient ID and randomized to one of the two groups. The participants and outcomes assessors will be blinded to treatment group allocation, but the physician administering treatment will not be blinded.

Exclusion Criteria:
* Patients with concomitant injuries or pain
* Full thickness tears of the affected tendon
* Prior corticosteroid injection of the affected tendon within the last 3 months
