Tendon Fenestration Versus Surgery for the Treatment of Chronic Lateral Epicondylosis

Canada64 participantsStarted 2016-06

Plain-language summary

Lateral epicondylosis, also called tennis elbow or lateral epicondylitis, is a prevalent, painful syndrome of the elbow. It is refractory to conservative treatment measures, including rest, excentric and concentric exercises in approximately 20% of patients after 6 months. Corticosteroid injections can provide relief in the short term. Mini-open surgery may be proposed when the conservative treatment fails and studies have shown an efficacy of 70%. Ultrasound-guided tendon fenestration is a minimally-invasive technique which stimulates the physiological healing mechanisms of the tendon and appears promising for the treatment of chronic tendinopathies. To our knowledge, no studies have compared the US-guided fenestration technique to mini-open surgery for the treatment of chronic lateral epicondylosis. The primary objective of this pilot study is to compare the efficacy of US-guided fenestration to mini-open surgery to reduce pain and improve functional status in workers suffering from chronic lateral epicondylosis refractory to 6-month conservative treatment. This is a prospective single-blind randomized pilot study. Sixty-four subjects will be randomized into two intervention groups for treatment either by US-guided fenestration or mini-open surgery. The primary outcome of the study will be the Patient Rated Tennis Elbow Evaluation (PRTEE) score at 6 month post-procedure.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Workers * Ability to read, understand and answer questionnaires in French or English * Diagnosis of unilateral, lateral epicondylosis established by an orthopaedist, determined by clinical presentation and pain, ≥ 4/10 on a pain numerical rating scale, on palpation of the region slightly anterior and distal to the lateral epicondyle, exacerbated by the extension of the wrist or the middle finger when the elbow is in extension. * Chronic epicondylosis, refractory to medical treatment conducted for at least six months, which includes rest and implementation of ergonomics to avoid soliciting the extensor tendons, and at least one of: physical therapy, a rehabilitation program with stretching and / or strengthening exercises, injection treatments (corticosteroids, autologous PRP) or extracorporeal shock waves. Exclusion Criteria: * Suspected tumor or infectious etiology * Injection of corticosteroids during the last 3 months * Hemorrhagic diathesis; anticoagulation (platelets \<50,000, International Normalized Ratio (INR) \> 2) * Local infection * History of elbow surgery or fracture * History of inflammatory arthropathy * Neck pain and radiculopathy * Inability to provide informed consent because of a language problem, dementia or a major psychiatric disorder.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
