What is a Meniscus?

The meniscus is the soft, fibrous shock absorber that rests in the knee between the femur and the tibia. When it is removed, pain and arthritis can develop.

What is Meniscus Allograft Transplantation?

Meniscus allograft transplantation involves taking a meniscus from a cadaver. The meniscus is tested to ensure that it is not contaminated and then frozen. When all of the tests are negative for contamination, it is provided to surgeons for meniscus transplantation. The technique of transplantation involves an arthroscopic outpatient surgery.

What are the Success Rates and Problems?

Success rates are highest in the youngest patients with the healthiest joints of course. However, pain can also be diminished in older patients with arthritis. The most common problem has been partial re-tearing of the transplanted meniscus which has required surgical suturing (repair), and rarely, complete replacement. Rejection of the meniscus has not been seen in our patients and only reported worldwide in a few cases.

What is the Recovery Time and Rehabilitation Program?

• Partial weight-bearing status for 4 weeks

• Most patients will be in a hinged rehab brace locked in full extension for 4 weeks

• No resisted leg extension machines (isotonic or isokinetic).

• No high impact or cutting/twisting activities for at least 4 months post-op.
