Dr. John O’Shea specializes in disorders of the knee, which allows him to treat all age groups with a variety of conditions from athletic injuries to arthritic conditions. These treatments include knee arthroscopy, ACL & ligament reconstruction, knee replacement surgery, and kneecap realignment. He also performs a type of partial knee replacement called KineMatch® Patello-Femoral Replacement (PFR).
As an orthopedic surgeon, he enjoys returning people back to their active lifestyles using both conservative and surgical approaches. When surgery is not the best option, Dr. O’Shea appreciates situations when he is able to improve someone’s knee condition with a nonoperative, conservative approach.
Outside of work, he enjoys hiking, swimming, cooking, music, guitar, and spending time with his family.
