“…However, the use of PRP in more unstable meniscal injuries such as radial lesions should not be discarded as it could be a valid option prior to meniscectomy. Previous studies have shown how this type of injury can be repaired instead of removing the meniscus [10, 16, 20].…”

Purpose To evaluate the eicacy of applying a combination of intrameniscal and intraarticular iniltrations of Platelet-Rich Plasma (PRP) in patients with meniscal tears, analyzing its failure rate and clinical evolution, as well as factors that may inluence the positive response to this treatment. Methods Three hundred and ninety-two cases out of 696 met the inclusion criteria and were included in this work. Survival and patient-reported outcome measure (PROM) were collected and analyzed. Survival rate was deined as the percentage of patients who did not undergo meniscus surgery during their follow-up time. Patients were asked to complete the Knee injury and Osteoarthritis Outcome Score (KOOS) at baseline, 6 months and 18 months. Other patient-and pathology-related variables were collected. Blood and PRP samples were randomly tested as a quality control measure. Survival and comparative statistical tests, and multivariate regression were performed for the analysis of the variables. ResultsThe PRP applied had a platelet concentration factor of 1.9X in respect to blood levels, with no leukocytes or erythrocytes. Thirty-eight patients required surgical intervention after treatment reaching a survival rate of 90.3% with an estimated mean survival time of 54.4 months. The type of injury (P = 0.002) and the presence of chondropathy were risk factors for surgical intervention after PRP treatment (P = 0.043). All KOOS scores showed a signiicant statistical increase from baseline to 6 months (N = 93) and 18 months (N = 66) (P < 0.0001). The number of cases with minimal clinically important improvement (MCII) at 6 months and 18 months post-treatment was 65 (69.9%) and 43 (65.2%), respectively. Conclusion The combination of intrameniscal and intraarticular PRP iniltrations is a valid conservative treatment for meniscal injuries avoiding the need for surgical intervention. Its eicacy is higher in horizontal tears and decreases when joint degeneration is present. Level of evidence Level IV.
