A Prospective, Single-blind, Randomized, Multi-Center Study Comparing Platelet Rich Plasma and Corticosteroid for Patients With Glenohumeral Osteoarthritis in the Military and Civilian Population
In Brief
A Phase 3 clinical trial evaluating Platelet Rich Plasma Injection, Corticosteroid Injection, and 1 other intervention for Osteoarthritis of the Shoulder and 3 related conditions. Completed, enrolled 50 participants across 1 site.
Detailed Summary
Shoulder arthroplasty provides successful improvement in pain and function for the treatment of end stage osteoarthritis (OA) of the shoulder in the older patient population (Sanchez 2008, Sampson 2010, Kon 2012, Fitzpatrick 2017). However, the optimal non-operative treatment for shoulder OA in the young active duty and civilian populations has yet to be determined. Although corticosteroid injections (CSI) are a viable option with diagnostic and short-term therapeutic benefit in glenohumeral OA, steroid does little to address the underlying pathology and confers risk of adjacent tendon failure (Kon 2009, Gosens 2011, Monto 2014, Tietze 2014). Platelet-rich plasma (PRP) derived from autologous blood, however, has the potential to enhance soft tissue healing as previously observed in muscles and tendons (Sanchez 2005, Randelli 2008, Hall 2009). PRP contains growth factors purported to safely facilitate local tissue regeneration as corroborated in multiple clinical studies investigating tendinopathy (Virchenko 2006, Kesikburun 2013, Fitzpatrick 2017, Schwitzguebel 2019). PRP is a promising concept to bridge the gap between conventional non-operative measures and surgical arthroscopy or arthroplasty options in a high functioning patient population with refractory disease. However, clinical literature elucidating the effects of intra-articular leukocyte-poor PRP (LP-PRP) injections in large joint degenerative OA has been slower to emerge, lacking substantiated data due to small sample sizes and treatment variability. Therefore, high level evidence-based studies remain critical in ascertaining the therapeutic value and clinical efficacy of LP-PRP in glenohumeral OA in order to establish standard of care protocols and guide systematic implementation.
Study Details
Timeline
Interventions
Minimum 2cc Leukocyte Poor Platelet Rich Plasma The PRP will be prepared by drawing 60cc blood from the participant through venipuncture, spinning the blood sample in a centrifuge and then injecting the platelet rich plasma (approximately 2-5cc or max collected) into the study shoulder using ultrasound guidance. This sample will be prepared by the study provider (physician assistant or physician). Any leftover blood will be safely discarded per standard protocols.
5cc Normal Saline + 2cc 10 mg/ml Triamcinolone Acetonide (Kenalog)
Participants randomized to the corticosteroid injection (CSI) group who report no improvement in their pain level at the 6 week post-CSI visit will be unblinded to their study injection (CSI) and will be offered the option to stay in the study and receive Platelet Rich Plasma injection.
