Meniscus Allograft Transplantation: Ten-Year Results of Cryopreserved Allografts

Meniscal Allograft Transplantation: Where are we Standing?

“…Also, several studies have reported a significant improvement in postoperative values of the Lysholm score compared to preoperative values [14][15][16][17][18][19]. Many studies found significant improvements after MAT in the International Knee Documentation Committee (IKDC) [11,14,15,17,18,20], with percentages between 70 to 90% of nearly normal or normal values [21][22][23]. MAT has provided most patients with pain relief, adequate return to sports, and excellent satisfaction [6][7][8][9]10,11,14,15,17,18,21,[24][25][26][27].…”

“…In general, the association of this ligament reconstruction to MAT does not worsen pain relief and clinical and functional outcomes when compared to isolated MAT [21,37,73]. Isolated procedures elicit a tendency towards better Lysholm [17], but lower physical-role (SF-36) [33] compared to combined procedures. There are also several studies employing osteotomy as combined procedure to MAT [6,7,9].…”

“…During the first 5 years after MAT, physicians can expect a mean Lysholm score of 80 points (range 60-100), with still values between 60 and 80 points at a follow-up between 10 and 20 years [7]. Also, several studies have reported a significant improvement in postoperative values of the Lysholm score compared to preoperative values [14][15][16][17][18][19]. Many studies found significant improvements after MAT in the International Knee Documentation Committee (IKDC) [11,14,15,17,18,20], with percentages between 70 to 90% of nearly normal or normal values [21][22][23].…”

In general, quality of life has even improved after MAT [28], with physical and mental component summary values above those for the matched U.S. population [22,23].…”

“…El Attar et al, found a mean failure rate of 10.6% and mean complications rate of 21.3% per trial in their systematic review [7]. Failure has been reported to occur at a mean of 2-3 years [32], 5 years [33], and 11.8 years [17]. The failure rate for medial allograft is higher compared to the lateral allograft [29].…”
