There are differences between the techniques for medial and lateral meniscal transplantation as a result of the characteristics of the anatomic attachment sites.
The lateral meniscus, with the anterior and posterior horns atached to a central bone slot, provides the most ideal transplant. The normal physiological hoop stress is maintained becuase the attachment sites and circumference tension relations are not disturbed. Careful sizing is necessary to locate the central bone slot in the host in the correct cornonal distance (lateral to medial) so that the meniscus body is adjacent to the peripheral edge of the tibial plateau and does not overhang at the tibial margin. A common mistake is not to adequately place the anterior horn attachment far enough medially to establish the correct weight-bearing position of the anterior horn.
This video covers additional surgical pearls to Dr. Noyes' VJO video on medial meniscal transplantion.
