Acetabular labral tear is a debilitating condition for which there are few effective non-surgical
treatment options. A number of studies in humans and in animal models suggest that the labrum may have a capacity for
spontaneous healing, and that therapies that seek to exploit and facilitate this process may be beneficial. Regenerative
injection therapies have shown promise in the treatment of several musculoskeletal disorders, but have not previously
been applied to labral tear.
We present an initial case series of 19 patients with labral tear that were treated in our clinic with intra-articular
injections of hypertonic dextrose. Patient-reported assessments were collected by questionnaire between 1 and 60 months
post-treatment (mean = 12 months).
All patients reported improvements in pain relief and functionality. Patients reported complete relief of 54% of
recorded symptoms. Improvements did not show dependence on the time between treatment and follow-up. No adverse
events were reported.
Regenerative injection therapy (prolotherapy) for acetabular labral tear appears to be a safe and potentially
efficacious procedure that merits further investigation as a non-surgical option.
