In regards to available treatment options for meniscus tears, here are my thoughts on meniscus transplantation.
Just as we transplant solid organs (i.e. kidneys), some patients are candidates for meniscus transplants. I recently had a 28 year old man who lost most of his lateral meniscus due to a bad injury. Given his age and activity level, he underwent a lateral meniscus transplant. This should alleviate his pain and more importantly, protect his cartilage from early degradation and arthritis.
