I did my residency at Hermann Hospital, University of Texas. Following that I went to Wrightington, England and did a fellowship in joint replacement with John Charnley. I started my practice in Houston in 1968, initiating joint replacement to this country in the form of hip replacement and subsequent knee replacement. I have been in practice since that time maintaining a significant record with this type of surgery. We have minimized complications using "clean air rooms" and continue this practice to this day.
