Meniscus Centralization and Its Effects on Meniscal Extrusion and Knee Biomechanics: A Systematic Review.

Recent research underscores the significance of meniscal extrusion in knee osteoarthritis progression. Centralization of the meniscus has emerged as a potential intervention, yet comprehensive literature on this is limited. This systematic review aims to synthesize evidence on meniscus centralization's impact on extrusion and knee biomechanics. A search of PubMed Central and Scopus yielded 14 relevant articles until June 1, 2023. Included were 3 case series, 9 cadaveric studies, and 2 involving animals or patients. Biomechanical effects on both medial and lateral menisci were explored, alongside implications for anterior cruciate ligament reconstruction. Findings suggest centralization may mitigate extrusion and improve knee biomechanics, potentially benefiting clinical outcomes. However, further high-quality studies are warranted to validate these observations and ascertain optimal centralization techniques.
