Platelet-rich Plasma vs. Hyaluronic Acid for Glenohumeral Osteoarthritis

Hospital for Special Surgery, New York70 enrolled

Overview

This study seeks to expand the current literature in demonstrating potentially efficacious, conservative treatments in the management of glenohumeral osteoarthritis (OA) and will compare ultrasound-guided injections of hyaluronic acid vs. platelet-rich plasma. We aim to obtain information measuring potential benefits of these interventions and to observe for any adverse events.

Glenohumeral OA accounts for approximately 2-5% of all chronic shoulder pain and may be classified into primary and secondary forms. Primary glenohumeral OA is caused by degenerative joint disease, inflammatory arthropathies, and neuropathic arthropathy secondary to syringomyelia or diabetes. Secondary glenohumeral OA is caused by trauma, postoperative changes after arthroscopy or capulorraphy, and osteonecrosis. Hyaluronic acid is found in synovial joint fluid and has viscoelastic, chondroprotective, and possibly anti-inflammatory properties. It has been shown to increase joint lubrication. Platelet-rich plasma contains growth factors that have been shown to promote tissue regeneration. The aim of this study is to determine whether injections of hyaluronic acid or platelet-rich plasma can be used reliably to decrease pain, restore function, and improve quality of life in patients suffering from glenohumeral OA. Patients will be randomized to receive either an injection of hyaluronic acid or an injection of platelet-rich plasma. Outcomes will be assessed via questionnaires for up to 52 weeks post-procedure.

Outcomes

Primary Outcomes

Shoulder Pain and Disability Index (SPADI) Score

Score ranges from 0-100, with a higher score representing higher disability.

Time frame: Up to 52 weeks post-procedure

Secondary Outcomes

Shoulder Function

Shoulder function will be assessed using the American Shoulder and Elbow Surgeons Society Standardized Shoulder Assessment (ASES) Form. The ASES forms includes questions about difficulty performing different functions, such as putting on a coat and sleeping on the affected side. Scores range from 0 to 100, with a higher score indicating higher function and a lower score indicating lower function.

Time frame: Up to 52 weeks post-procedure

Number of Patients Who Were Satisfied After Treatment

Satisfaction will be assessed using the North American Spine Society Patient Satisfaction Index. Patients were asked to select one of the following in regards to the procedure: "The procedure met my expectations"; "The procedure improved my condition enough so that I would go through it again for the same outcome"; "The procedure helped me, but I would not go through it again for the same outcome"; or "I am the same or worse compared to before the procedure". Responses of "The procedure met my expectations" and "The procedure improved my condition enough so that I would go through it again for the same outcome" were considered to be "satisfied". The other two responses were considered to be "not satisfied".

Time frame: Up to 52 weeks post-procedure

Number of Patients With Complication Events After the Procedure

Any complications reported were collected. Complications include bleeding from the injection site, prolonged swelling, infection, weakness of the muscles surrounding the injected joint, and allergic reactions. Total number of available events was calculated by multiplying the number of patients with the number of follow-up time points. The percentage of complication events was calculated by summing the number of complication events and dividing that by the total number of available events, and then multiplying by 100.
