MENISCAL ALLOGRAFT TRANSPLANTATION COMBINED WITH ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION: A SYSTEMATIC REVIEW.

Abstract

To evaluate the clinical and functional outcomes of meniscal allograft transplantation (MAT) with anterior cruciate ligament reconstruction (ACLR) in a single surgical stage through a systematic review of the currently available evidence. A systematic search of the PubMed and Google Scholar databases, with no publication date limit, until December 2022 was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Follow-up studies and case series published in English involving patients undergoing a combination of ACLR and MAT were included. The quality of these studies was assessed using the Methodological Index for Non-Randomized Studies (MINORS) checklist. A systematic review of the International Knee Documentation Committee (IKDC), Lysholm and Tegner activity scores was conducted. Seven studies involving 154 patients were included. The mean follow-up was 5,3 years. The mean age at the time of the surgery was of 35.3 years. All studies used the Lysholm Knee score, IKDC score or Tegner activity score to measure clinical outcomes post-operatively and the mean improvements were 26.7, 24.7, and 1.8 respectively. The rate to return to sport was 75.5 %. No intra-operative complications were reported. The post-operative complication rate was 11.6%. MAT combined with ACLR procedure showed good clinical results up to an average of 5 years of follow-up. More studies need to be conducted that can better understand the long-term effects of this combined procedure.
