Meniscal Allograft Transplantation - Series

Normal Anatomy

There are two cartilage rings in the center of each knee, one on the inside (medial meniscus) and one on the outside (lateral meniscus).

Normal anatomy

Indications

If the meniscus tears are severe that all or nearly all of the meniscus cartilage has to be removed, then a meniscal allograft procedure may be recommended. The new meniscus can help knee pain and possibly prevent future arthritis. The new meniscus is an allograft, a tissue taken from a cadaver.

Indications

Procedure, Part 1

The meniscus transplant is usually performed by using small instruments through tiny incisions (knee arthroscopy). After the surgeon inspects the knee using a tiny camera, tunnels are drilled into the joint.

Procedure, part 1

Procedure, Part 2

The damaged meniscus is removed by using a shaver or other instruments. The meniscal allograft is prepared to fit the joint then inserted through a small incision in the front of the knee. The allograft is sutured and pulled into place.

Procedure, part 2

Procedure, Part 3

Additional sutures are used to secure the meniscal transplant into place. Screws or other devices may be used as well.

Procedure, part 3

Aftercare

The incisions are closed, and a dressing is applied. A decrease in knee pain can be expected in up to 80% of patients after meniscal allograft transplantation.
