Evaluation of TENEX for Greater Trochanteric Pain Syndrome (GTPS)
- Conditions
- Greater Trochanteric Pain Syndrome
- Interventions
- Device: TENEX
- Registration Number
- NCT05710627
- Lead Sponsor
- Montefiore Medical Center
- Brief 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 guide the partial release of gluteus medius and minimus and Iliotibial band tendons in patients diagnosed with refractory Greater Trochanteric Pain Syndrome (GTPS) vs control. The investigator team hypothesizes that the new TENEX can improve the pain level for individuals with GTPS to help those individuals perform their activities of daily living (ADLs), e.g., walking, standing, and side-lying, as well as demonstrate less medication utilization. The study predicts that this percutaneous outpatient procedure can decrease pain, increase mobility, and decrease medication utilization.
The study team hypothesizes that PUT can improve the pain level and function for individuals suffering with GTPS. The study will assess walking, standing, and side-lying tolerance, as well as medication utilization. The investigator team predicts that this percutaneous outpatient procedure can decrease pain and medication utilization while increasing mobility.
- Detailed Description
Greater trochanteric pain syndrome (GTPS) is one of the most common causes of lateral hip pain in adults. GTPS is repetitive overload tendinopathy of the gluteus medius (GMed) and Iliotibial band (ITB), which play a primary role in hip abduction and pelvic stabilization in walking, stair climbing, running and standing on one leg. It is thought that the core pathology is greater trochanteric bursitis (TB) with or without coexisting gluteal tendinopathy. Some common etiologies include prolonged excessive pressure to the area, injury to the side of the hip, and repetitive movements; however, local steroid injections to the greater TB are not often successful over the long-term. The best estimates of prevalence are from a large, community-based study with over 3000 adults aged 50 to 70 years, in which unilateral GTPS was present in 15 percent of women and 6.6 percent of men. Patients who have not improved after at least 12 months of conservative medical management (CMM), including physical therapy, oral medications, or a local steroid injection have no other conservative treatment recourse. Open surgery for GMed or ITB tears is not recommended unless a tear is diagnosed on MRI. Based on a published study, a 60% improvement was shown in pain with the performance of TENEX of the GMed.
The purpose of this project is to study the outcome of GMed and ITB PUT on CMM refractory GTPS. We want to quantify and show the scales of the pain in pre-operative and post-treatment cases. We also want to see how effective the surgery is in specific terms of pain levels because GTPS is a pain syndrome and reduction in pain level is the most important clinical factor.
Patient Reported Outcome Measure (PROM) is one of the main outcomes that medical research is validated with and through this study we want to show the most important outcome of GTPS i.e., pain level (PROM for GTPS). Previous studies which focused on surgical outcomes have been mostly single-center trials.
Pain and mobility impact patients' Quality of Life (QoL) and medical cost burden due to unemployment, psychosocial well-being, and functional dependence. The standard of care offered to address the pain and mobility needs of those with GTPS is to provide CMM, followed by open or arthroscopic surgery if surgery is indicated. However, there is a treatment gap for those patients who have failed CMM and are not surgical candidates. The authors submit that TENEX of the GMed and ITB may address this gap. The results from this research may have broad impacts on the treatment algorithm for patients with GTPS.

- Primary Outcome Measures
Name Time Method Pain Level Baseline (before treatment), 1 month, 3 months, 6 months, 1 year, and 2 years The difference in pain levels in patients before and after the procedure. Pain levels (NRS scale) recorded in the pre-operative visit will be compared to the pain levels at follow-up (FU) visits. The Numeric rating scale (NRS) is a pain screening tool used to assess pain severity using a 0-10 scale, with 0 meaning no pain and 10 meaning the worst pain imaginable. Pain level scores will be summarized by study arm. Achievement of 50% reduction in pain level from baseline at 6 months post treatment will be considered successful.
- Secondary Outcome Measures
Name Time Method Quality of Life using the European Quality of Life 5 Dimensions 5 Level Version (EQ-5D-5L) Baseline (before treatment), 1 month, 3 months, 6 months, 1 year, and 2 years A comparative analysis between TENEX to conventional medical treatments will be conducted using the EQ-5D-5L. Walking, side-lying, sit-to-stand transfers, and medication utilization will be assessed. The EQ-5D-5L is a descriptive system which comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1- digit number that expresses the level selected for that dimension. The digits for the five dimensions are combined into a five-digit number that describes the patient's health state. Results will be summarized by study arm.
