Clinical Trial: Blood Cell Ratios as Predictors of Response to Platelet-Rich Plasma in Knee Osteoarthritis

U.S., June 2 -- ClinicalTrials.gov registry received information related to the study (NCT07617233) titled 'Blood Cell Ratios as Predictors of Response to Platelet-Rich Plasma in Knee Osteoarthritis' on May 20.

Brief Summary: Intra-articular platelet-rich plasma (PRP) injection is a widely used treatment for knee osteoarthritis, but patients respond to it very differently and there is currently no simple, inexpensive way to predict who will benefit. The neutrophil-to-lymphocyte ratio (NLR) and related indices derived from a routine complete blood count reflect a person's baseline inflammatory state. This prospective single-arm observational cohort study investigates whether the baseline NLR, together with the platelet-to-lymphocyte ratio (...
