Surgery is the last quiet conversation between a body and the person who will carry it forward.

For seventeen years, my practice has been built on a stubborn idea: that orthopaedic surgery is not a transaction, and that a knee is not a knee. It belongs to the violinist who needs to crouch, the parent on the floor with their child, the runner whose Sunday is a pilgrimage.

I will not operate on a patient whose problem can be answered by movement, time, or honesty. When surgery is the right answer, it is approached the way a luthier approaches a violin — with patience, planning and a respect for what was working before.

High volume in a small set of operations is, in our view, the fastest path to good outcomes. Tap a region.
