Lesions of the glenoid labrum are a common cause of shoulder instability and a frequent finding in patients with shoulder pain. Management of these patients typically involves an attempt to avoid surgery through conservative treatment. However, there is currently a dearth of conservative options that promote labral healing. Regenerative injection therapies, including prolotherapy, have shown promise in the treatment of several musculoskeletal disorders, but have not previously been applied to glenoid labral tear. Here we review several important aspects of these lesions and present an initial case series of 33 patients with labral tear that were treated in our clinic with intra-articular injections of hypertonic dextrose. Patient-reported assessments were collected by questionnaire at a mean follow-up time of 16 months. Treated patients reported highly significant improvements with respect to pain, stiffness, range of motion, crunching, exercise and need for medication. All 31 patients who reported pain at baseline experienced pain relief, and all 31 who reported exercise impairment at baseline reported improved exercise capability. Patients reported complete relief of 69% of recorded symptoms. One patient reported worsening of some symptoms. Prolotherapy for glenoid labral tear appears to be a safe procedure that merits further investigation.
