About this trial

The investigators hypothesize that a single injection of platelet-poor plasma (PPP) into an acute muscle injury will significantly improve local muscle regeneration and patient outcomes compared to the standard of care using only ultrasound-guided hematoma aspiration. Muscle regeneration will be assessed through quantitative MRI analysis. The investigators anticipate that PPP injections will lead to a measurable reduction in scar tissue and an increase in regenerated muscle tissue at the injury site over a six-month period.

Change in Scar Tissue Volume at the Muscle Injury Site as Measured by Quantitative MRI Mapping

Scar tissue volume at the site of acute muscle injury will be measured using quantitative mapping magnetic resonance imaging (MRI). MRI images will be segmented using software to identify abnormal (scar) tissue within the injured muscle. Scar tissue volume will be calculated in cubic centimeters (cm³). This outcome measure represents the change in scar tissue volume, calculated as the difference between baseline MRI and 6-month follow-up MRI measurements. A lower scar tissue volume indicates greater muscle regeneration and reduced fibrosis.
