SUMMARY — THE REDUCTIONThis review examines whether meniscus allografts truly integrate biologically, noting revascularization is shown only in animals, time-zero biomechanics are adequate with graft sizing within 10% and bone plug fixation, and fresh versus frozen type does not matter.
Abstract, as published

» After transplantation revascularization does occur although data are only available for animal models.» The time zero biomechanics, that is, the biomechanical properties at the time of transplant, of a meniscus allograft transplantation appear to appropriately mimic the original so long as the graft is sized correctly within 10% of the original and bone plug fixation is used.» Allograft type, that is, fresh vs. frozen, does not appear to affect the integration of the allograft.
