Meniscus allograft transplantation: indications, techniques and outcomes

Abstract

New indications for meniscal allograft transplantation (MAT) are being added, but the general expert opinion is that it is still a procedure reserved for symptomatic meniscal loss.

Lateral MAT has better clinical outcomes and less failure risk compared to medial MAT.

Ideal conditions (low-grade chondral lesions) make MAT a more survivable and successful procedure.

Meniscal extrusion after MAT is common and does not seem to alter results.

Midterm survivorship of a MAT is reported to be 85–90%, while long-term survivorship decreases to 50–70% depending on chondral status and concomitant procedures.

Even if the procedure is a success, there are high possibilities of not being able to resume sports activities.
