Meniscal injuries are among the most common knee injuries and result in over 1 million surgeries a year in the US. Menisci have limited repair capability and injury results in pain, swelling, mechanical instability, and increased risk for osteoarthritis. Currently the only treatment for whole meniscal replacement are cadaveric allograft transplantations, which are limited in supply, carry a risk of disease transmission, and can have size matching issues. Additionally, the meniscus requires an attachment into bone, an enthesis, to function properly. The strength of this attachment is correlated with patient recovery and is necessary for a full meniscus replacement.

We have developed an anatomically correct high density collagen meniscus and are currently investigating and the use of chemical and mechanical stimulation to improve the organization of collagen and mechanical properties of tissue engineered menisci and enthesis.
