Dr. John Diana is a leading provider of joint replacement surgery in the Bay Area. Specializing in hip and knee replacements, Dr. Diana performs over 600 joint replacement surgeries each year and teaches anterior hip replacement techniques as well as MAKO robotic knee replacement procedures to surgeons from all over the U.S. and Asia.
For the knee, Dr. Diana performs: robotically-assisted total knee replacement, robotically-assisted partial knee replacement, computer navigated knee replacement, quadriceps-sparing minimally invasive knee replacement, and revision knee replacement surgery.
For the hip, Dr. Diana performs Birmingham hip resurfacing arthroplasty, direct anterior hip replacement surgery, and revision hip replacement surgery.
Committed to providing the highest technology available improving outcomes for patients, Dr. Diana supports MAKO robotic knee replacement procedures and robotic technology. Throughout the country, he teaches labs for surgeons to learn this technology. Robotic technology has the ability to improve surgical planning, offer additional tools to assess alignment, yield quantitative information to enhance ligament balance, and lessen the incidence of soft tissue injury.
Using the Direct Anterior Approach hip replacement (DAA) for over 10 years and for most of his surgeries, Dr. Diana developed extensive experience allowing his patients to enjoy the amazing benefits of this surgery. Specifically, anterior approach hip replacement can:
- Result in enhanced stability, allowing no “hip precautions” in the postoperative period usually instituted with posterior approach replacement techniques
- Allow the surgeon to take intraoperative x-rays to improve the accuracy of position of the components
- Decrease time spent using assistive devices postoperatively such as a walker/cane
- Offer a muscle-sparing path to enter the hip joint without disconnecting any deep tendons
- Eliminate the need for special items like elevated toilet seats and reaching tools postoperatively
The non-profit organization ProPublica has recognized Dr. Diana for his high quality and exceedingly low adjusted complication rate for hip replacement in the region. He is also listed in the 2018 Sonoma Magazine as a “Top Doc.”
Dr. Diana’s Adusted Complication Rate Chart for hip replacements is as follows:

I have always had a very active life style and was growing increasingly frustrated when painful and undependable knees forced me to restrict my activities…
