简要总结
This is an observational study that evaluates the characteristics of Platelet Rich Plasma used in the therapy and treatment of musculoskeletal injuries and degenerative joint diseases.
A sample of the PRP will be tested for platelet and microparticle content using dynamic light scattering to determine if there is a relationship between the composition and the treatment outcome.
详细描述
An observational study that evaluates the characteristics of Platelet Rich Plasma used in the therapy and treatment of musculoskeletal and degenerative joint conditions.
Patients enrolled in this study have already been assessed by the Principal Investigator and are schedule to receive treatment with Platelet Rich Plasma. Prior to the treatment patients will be asked to consent in the study where the composition of the PRP is to be evaluated. Consenting patients that meet inclusion/exclusion criteria will complete a pain score self-assessment prior to treatment.
An autologous preparation of PRP sample will be made from the subject's whole blood. The subject will receive the PRP treatment and an excess portion of the PRP preparation will be tested for composition and the relative concentration of the constituents.
The sample of the PRP will be tested using Dynamic Light Scattering (ThromboLUX System) to measure the constituents in PRP preparations prior to injection. PRP and whole blood (at physician's discretion) will be analyzed on a hematology analyzer.
The testing work-flow does not alter the subject's standard of care. The physician will be blinded to the analytical results during the enrolment, treatment and patient follow-up phase of the study. Analytical results are not used in patient management decisions.

结局指标
主要结局
Change in pre- and post- pain score at 3 and 6 weeks
时间窗: Up to 6 weeks after injection
The primary objective of the study is to test the hypothesis that the constituents in platelet-rich plasma (PRP) preparations, such as platelet and microparticle content and composition, can be correlated to the clinical outcome for PRP treatments.
The impact of microparticle content on pain scores
时间窗: Up to 6 weeks after injection
The study will ascertain the capability of ThromboLUX microparticle assay results to correlate with the clinical outcome for PRP treatments when evaluated by patient pre- and post-pain score assessment.
次要结局
- Correlation of platelet count to ThromboLUX results(Up to 6 weeks after injection)
- The use of dynamic light scattering (ThromboLUX) as a patient screening tool(Up to 6 weeks after injection)
