Serial ultrasonographic imaging can predict failure after meniscus allograft transplantation.

US assessments of meniscus allografts at 6 months after transplantation can effectively determine risk for short-term failure. Abnormal meniscus echogenicity, persistent localised effusion and extrusion with weightbearing were associated with 8-15 times higher odds for failure, which occurred at a median of 20 months post-transplantation.
