ABSTRACT
Despite careful preoperative and intraoperative sizing of lateral menisci in recipient
knees, size mismatches between allografts and recipient menisci are often encountered.
To minimize size mismatches during the transplantation of smaller than expected lateral
meniscal allografts, we devised a modified keyhole technique by dividing the central
bone bridge into 2 bony fragments. The fragments are attached to the anterior and
posterior horns. In the event of mismatch, the anterior bony fragment is moved anteriorly
in the keyhole tunnel. Although the technique of meniscal transplantation is technically
demanding, the central bone bridge can be divided without difficulty. The described
technique is considered a useful alternative method during lateral meniscal transplantation.
