Surgery on the Windward side

For patients in Kailua, Kāne‘ohe, Waimānalo, and up the Windward coast, Adventist Health Castle offers hospital-based hip and knee replacement minutes from home — which matters more than people expect. Early recovery is easier when family can visit without a Pali commute, and follow-up logistics stop competing with your healing. Robotic-assisted knee replacement is available here too — at Castle, Dr. Morton uses the CORI system, which builds its plan in the operating room rather than from a CT scan beforehand — and qualified hip and knee patients can go home the same day.

Venue is a decision, not a default

Dr. Morton operates at more than one O‘ahu hospital precisely so geography can serve the patient: same-day robotic knee replacement and complex work at Queen's, and community-hospital settings like Castle when they fit your case and coverage. Revision surgery is done at both hospitals: at Queen's for most patients and at Castle for some. Clinic visits happen at Ala Moana or Kunia, with telehealth filling gaps for busy Windward schedules.

Frequently asked questions

Can Windward patients do everything on their side of the island?
Surgery can happen at Castle; clinic visits currently use the Ala Moana or Kunia offices plus telehealth. Many Windward patients pair video follow-ups with a single clinic visit to keep driving minimal.
Does insurance affect which hospital I can use?
Sometimes — networks and facility contracts vary by plan. The office checks your benefits and tells you which venues your plan supports before anything is scheduled.

Take the first step toward moving without pain
