Introduction: The increase in symptomatic knee patients and osteoarthrosis in young patients with limited therapeutic options after a meniscectomy generates an unmet need to search for alternative treatment. Although meniscal allograft is unfrequently used in Colombia, it is an alternative for symptomatic patient management. In the US, annually are practiced between 700.000 and 1.500.000 knee arthroscopies, 50% correcting meniscal tears with 40% of symptomatic persistence after this procedure.Methods: Retrospective cohort study evaluating the clinical outcome (pain and functionality) of patients with a second knee meniscectomy or meniscal transplant using Visual Analogue Pain Scale (VAPS) and Tegner y Lysholm scale, between 2007 and 2015.Results: Meniscal allograft VAPS score after 6 months, showed a trend toward improvement, changing from Moderate to Mild (p: <0.000). Tegner and Lysholm Scale changed from Poor to Good in second meniscectomy patients (p= 0.008) and from Good to Excellent in the meniscal allograft group (p=0.225). VAPS average score showed improvement on meniscal allograft patients (p=<0.000), unlike second meniscectomy group (p=0.591). Tegner and Lysholm Scale showed statistical significance only prone to improvement on second meniscectomy group. It is required a prospective cohort in order to analyze the outcomes of meniscal allografts. Discussion: Results showed an improvement in pain and functionality outcomes with meniscal allograft versus second meniscectomy. In order to strengthen the evidence, complementary prospective studies are needed.
