Hip & Knee Joint Replacement with Dr. Douglas Petraco
If you’re looking for an orthopedic surgeon in Riverhead for ongoing hip or knee pain, Dr. Douglas Petraco offers focused joint replacement care at the Riverhead office at 715 Roanoke Avenue. A board-certified orthopedic surgeon and Fellow of the American Academy of Orthopaedic Surgeons, Dr. Petraco concentrates specifically on hip and knee joint replacement rather than general orthopedics — so you’re seeing a surgeon who performs these procedures routinely.
When to See an Orthopedic Surgeon for Joint Pain
Most hip and knee problems Dr. Petraco treats stem from arthritis that has worn down the joint over time. When pain and stiffness start limiting how you walk, work, or sleep — and conservative measures like activity changes, weight management, physical therapy, or injections no longer help — it’s worth talking with a joint replacement specialist. Dr. Petraco evaluates each joint individually and recommends surgery only when it’s the right step.
Hip Replacement in Riverhead
Dr. Petraco performs total hip replacement for patients whose hip arthritis or joint damage no longer responds to conservative care, including advanced cases involving osteoarthritis or avascular necrosis. He emphasizes mini-incision technique where appropriate, which works through a smaller opening to spare surrounding tissue and support a more comfortable recovery. The goal is straightforward: relieve the pain that’s limiting you and restore stable, natural movement.
Knee Replacement
Dr. Petraco also performs total, partial, and robotic-assisted (MAKOplasty) knee replacement, along with knee arthroscopy. For details on his knee care in Riverhead, see the dedicated Knee Replacement in Riverhead page.

As Medical Director of Precision Care Surgery Center in East Setauket, Dr. Petraco performs ambulatory (same-day) hip and knee replacement. Using advanced anesthesia and minimally invasive technique, many appropriate candidates recover at home the same day rather than staying in a hospital.
