I am looking into the possibility of having a meniscus transplantation for my left knee. When I had the meniscus removed I was on crutches for about a week and no real exercises. Can I expect the same with this operation?

Meniscal transplantation is a fairly new operation. Studies comparing the results using different rehab programs haven't been reported. There's no clear agreement on the best approach at this point.

In general you can expect some restrictions in motion and weight bearing until healing has taken place. This may take two to three months. Details of your rehab may vary depending on whether or not you have any other repairs done at the same time. Many patients with a torn meniscus also have a ruptured anterior cruciate ligament (ACL).

Motion is important after ACL repair to prevent scar tissue and adhesions from forming. Too much motion can disrupt the meniscal graft. Your doctor may prescribe a hinged knee brace for the first six weeks. The brace can be used to control how much weight and shear is put on the graft.

Patients can return to light work in about a week. Strenuous work can be resumed three to four months after the operation. Low-impact activities begin at eight weeks. Running is allowed after four to five months. Light sports are okay but high speed, high-impact activities are not allowed even after rehab is done.
