Clinical Trial Summary

This is a randomized double-blinded randomized comparison between injection of platelet rich plasma (PRP) and placebo for thumb basale osteoarthritis.

Description:

The aim of this study is to evaluate if high-concentration PRP injection decreases pain and disability in patients with thumb base osteoarthritis in the short-term and compare the effect to placebo.90 patients will be inlcuded (45+45). The primary outcome is pain on load (numerical rating scale) after 6 months. Patient-rated outcome measures, pinch grip and key pinch, range of motion of the CMC.1 joint will be assessed before treatment and at 3, 6 and months after the injection. Participants and assessors will be blinded.
