Why patients choose Dr. Flowers

Dr. Flowers spent years as a licensed physical therapist before medical school, then trained in limb lengthening and complex reconstruction at the Hospital for Special Surgery, the top-ranked orthopedic hospital in the country. He knows what the months after surgery ask of you, and he plans each replacement with that recovery in mind. For patients whose joints are worn but not ready for a new one, he also practices joint preservation.

Hip and knee replacement with Dr. Flowers

Dr. Flowers performs total hip and total knee replacement. He, Dr. Chin and Dr. Gheewala make Sterling Ridge one of the leading joint replacement practices in the Houston area, replacing hips and knees every week.

For the hip, he uses the anterior approach whenever your anatomy allows it. He enters from the front of the hip, between the muscles instead of through them, which is why most patients are up and moving sooner in the first weeks. By a year out, both approaches end up in about the same place, and he will say so when you ask.

For the knee, he is certified on the Mako robotic arm. A CT scan builds the plan before surgery, and the robot keeps the cuts to that plan in the operating room.

Most of his replacements are same-day surgery at the Sterling Ridge / Woodforest Ambulatory Surgical Center on the Woodforest campus in Montgomery, built with Memorial Hermann. Physical therapy and the aquatic therapy pool are on the same campus, so the rehab he cares about starts where the surgery happened.

He sees patients at The Woodlands, Spring and Woodforest offices, Monday through Friday, 8:00 AM to 5:00 PM, and operates at the Sterling Ridge / Woodforest Ambulatory Surgical Center as well as several area hospitals, depending on insurance and medical needs. No referral is needed. Start with the hip replacement hub, the knee replacement hub, or the cost and insurance page.

Patients also ask

Does Dr. Flowers use the anterior approach for hip replacement?

Yes, for most first-time hip replacements. In a 2023 review of 24 randomized trials, it gave about 8 more points of hip function at six weeks and a stay a third of a day shorter, with about 17 extra minutes in surgery and no difference in dislocation, fracture or blood clots (Ang et al., 2023). If your anatomy or past surgery favors another approach, he will explain why.

Is my hip replacement outpatient?

Usually. Most healthy patients go home the same day from the Sterling Ridge / Woodforest Ambulatory Surgical Center. The American Association of Hip and Knee Surgeons calls outpatient joint replacement safe and effective for properly selected patients (AAHKS position statement). Your health, your help at home and the complexity of the case decide it, and Dr. Flowers will tell you which applies to you.

Does he also do knees?

Yes. Dr. Flowers performs total knee replacement, including Mako robotic-assisted knee replacement, and does it every week alongside his hip work. For a knee that is worn but not ready for a new joint, he also offers joint preservation options. The knee replacement hub covers candidacy, cost and recovery.
