Menisci are precious and necessary components of a knee joint. After meniscal tear surgeries, knee arthritis occurs proportionate to removed menisci volumes in surgeries. Menisci allograft transplantation is the most accepted treatment for preventing knee arthritis due to lack of menisci tissue. Literature states that successful transplantations prevent arthritis of the knee for up to 20 years. Medial and lateral menisci have different anatomies; therefore, their transplantations require different surgical methods.
