PUBLICATIONS

Being actively involved in research and innovation is important to me and allows me to be at the forefront of knee surgery. Below I have separated publications that I have authored into the different fields of knee surgery that may be most relevant to your knee injury or diagnosis.

Abstracts and some articles are available online, but please contact me if you would like full manuscripts.
