Clinical Trial Summary
The purpose of this study is to investigate a case series of patients treated with
Platelet-rich plasma for thumb carpometacarpal joint osteoarthritis. Carpometacarpal
arthritis is a highly prevalent condition with significant effects on quality of life and
function. Meanwhile, platelet-rich plasma has been demonstrated to be an effective treatment
for various musculoskeletal conditions.
Description:
The first carpometacarpal (CMC) joint at the base of the thumb is one of the most commonly
affected joints by osteoarthritis (OA), with a prevalence ranging from 15-36% in females and
5-11% in males. It is also functionally debilitating, with symptoms including diminished
range of motion, weakness, deformity, instability, and pain. Despite the prevalence of first
CMC OA, as well as the emerging evidence of platelet-rich plasma (PRP) efficacy for various
musculoskeletal conditions, there is a paucity of studies investigating the two. To our
knowledge, there are three studies in the literature, resulting in a total of 27 patients
with first CMC OA receiving PRP to date1.
Common nonsurgical treatment options for management of this condition include oral and
topical NSAIDs, hand therapy, activity modifications, splinting and intra-articular
injections. Injections have traditionally consisted of corticosteroids demonstrating variable
efficacy and viscosupplementation resulting in conflicting results. Surgical options include
trapeziectomy with ligament reconstruction and tendon interposition, fusion, and less
commonly, implant arthroplasty.
PRP is defined as an autologous, concentrated mix of platelets and inflammatory mediators
suspended in plasma, obtained by centrifuging a patient's whole blood. It is hypothesized
that PRP stimulates recruitment, proliferation, and differentiation of regenerative cells via
release of various growth factors such as platelet-derived growth factor-AB and -BB,
transforming growth factor-β1, insulin-like growth factor-1, fibroblast growth factor-basic,
epidermal growth factor, vascular endothelial growth factor, and interleukin (IL)-12. The
platelets in PRP have anti-inflammatory properties with modulators including IL-1 receptor
antagonist, soluble tumor necrosis factor receptor I and II, IL-4, IL-10, IL-13 and
interferon γ. Although PRP has been used for numerous musculoskeletal conditions, varying
methods of extraction, different types of PRP, and lack of standardized reporting on the
detailed biologic makeup of PRP has caused difficulties with interpretation and comparison of
studies investigating its use. For these reasons, there has been a call for the
standardization of PRP in clinical use.
The primary aim of this study was to assess (1) outcomes of PRP injection among patients with
first CMC OA, and (2) the biologic characteristics of PRP injectate. The secondary aims were
to describe the injection technique used at our institution and analyze the relationships
between patient demographics, PRP biologic characteristics, and patient outcomes.
