Meniscus transplant, also known as meniscal transplant or meniscal allograft transplantation, refers to the surgical procedure of replacing a damaged or removed meniscus with healthy meniscus tissue from a donor. Another synonym for meniscus transplant is meniscus replacement surgery. Sometimes, the term meniscus repair surgery may also be used to describe a similar procedure that involves stitching the damaged meniscus together to promote healing. Other related terms include arthroscopy, which is a minimally invasive technique for diagnosing and treating joint problems, and knee replacement, which involves replacing the entire joint with an artificial implant. The goal of meniscus transplant is to reduce pain and improve joint function in patients with knee injuries or degenerative conditions.
