Glenoid Labral Tear: follow up case series on ultrasound guided autologous platelet rich plasma in conjunction with a progressive rehabilitation program [version 1; referees: 1 approved, 1 approved with reservations, 1 not approved]
Background: Labral tears commonly occur in both the general and sporting population, often leading to significant pain and dysfunction. Patients often engage in progressive rehabilitative programs, and surgical intervention may be required in severe cases. Autologous platelet rich plasma (PRP) injections have been growing in popularity in musculoskeletal medicine as an alternative to corticosteroid injections. This paper looks at the effectiveness of PRP injections in glenoid labral lesions.
Methods: The clinical and radiological findings are presented for two patients who have been treated with autologous PRP into the glenohumeral joint adjacent to the labral tear, in conjunction with a progressive rehabilitative program. Follow up occurred at 18 months and 13 months, respectively.
Results: Both subjects tolerated the PRP injection well with no adverse effects, and were compliant with their rehabilitative programs. On initial presentation, pain on the visual analogue scale (VAS) was 7/10 and 6/10 and at follow up it was reported as 0/10. Both subjects have now returned to normal sporting and work activities.
Conclusions: The findings from this case series suggest that PRP in conjunction with appropriate rehabilitation can assist in the clinical recovery of glenoid labral tears. Further research is required with greater sample numbers and improved methodological parameters.
