Verdonk et al. report Kaplan-Meier survivorship for 100 viable meniscal allograft procedures (39 medial, 61 lateral) performed between 1989–2001, asking how long clinical benefit persists and whether concomitant procedures affect survival. Allografts were cultured for two weeks pre-implantation to preserve cell viability; follow-up averaged 7.2 years.
When planning medial meniscal allograft transplantation, always assess limb alignment on standing radiographs: varus malalignment requires concurrent high tibial osteotomy, as isolated medial MAT in a varus knee carries higher failure risk and axial correction demonstrably improves graft survival.
A patient with very low preoperative pain scores on the modified HSS scale (suggesting severe pain) warrants careful counseling, as this was the one preoperative factor significantly associated with failure.
