Brief Summary

The glenohumeral joint is the third most common large joint to be affected by OA. Conservative treatments include physical activity, corticosteroid injections, and medications. PRP is an emerging treatment that has shown efficacy in different musculoskeletal conditions. The use of PRP for glenohumeral OA has been described sparingly in the literature but has shown efficacy in a couple studies and case reports. However, all of the previous studies investigating PRP for glenohumeral OA have focused on low-dose PRP preparations (\~3X), and none have compared PRP treatment to saline treatment. This study aims to compare outcomes following single injections of low-dose PRP, high-dose PRP, or saline in patients with glenohumeral osteoarthritis.

Outcome Measures

Primary Outcomes (1)

  • American Shoulder and Elbow Surgeons (ASES) Shoulder Score

    The ASES measures pain and function in activities of daily living related to the shoulder. On a 100-point scale, a higher score represents less pain/higher function.

    3 months post-injection

Secondary Outcomes (6)

  • Average numerical rating scale (NRS) pain score

    Up to 12 months post-injection

  • Patient-Reported Outcomes Measurement Information System (PROMIS)-10 Global Health measure

    Up to 12 months post-injection

  • PROMIS-Upper Extremity computer adaptive test (CAT)

    Up to 12 months post-injection

  • Medication use

    Up to 12 months post-injection

  • PROMIS Sleep Disturbance

    Up to 12 months post-injection

  • +1 more secondary outcomes

Study Arms (3)

Low-dose PRP

EXPERIMENTAL

Patients will receive a single injection of 6 ml low-dose platelet-rich plasma (PRP) into the glenohumeral joint. Low-dose is defined as a platelet yield of 3X (i.e., 3-fold increase in platelets in PRP compared to whole blood).

Biological: Low-dose PRP

High-dose PRP

EXPERIMENTAL

Patients will receive a single injection of 6 ml high-dose platelet-rich plasma (PRP) into the glenohumeral joint. High-dose is defined as a platelet yield of 12X (i.e., 12-fold increase in platelets in PRP compared to whole blood).

Biological: High-dose PRP

Saline control

PLACEBO COMPARATOR

Patients will receive a single injection of 6 ml saline into the glenohumeral joint.
