Sound familiar?
- You've quietly given up things — the long walks, the second round, the trip — and called it "slowing down."
- You plan your day around how much your knee has left in it.
- You've had the X-ray, heard "bone-on-bone," tried the injections, and you're wondering what's actually next.
If that's you, keep reading. The rest of this page walks you through exactly what our surgeons would tell you in the exam room — no appointment required, no pressure attached.
Do I need a knee replacement?
A total knee replacement resurfaces the worn ends of the knee with metal and medical-grade plastic, relieving bone-on-bone arthritis pain that no longer responds to other treatment. It's the right move only after the simpler ones are used up — and about a third of the people who ask us this question hear "not yet."
The path most knees actually take
- Symptoms
The knee starts negotiating
Aching after activity becomes aching during it, then at rest, then at night. Stairs, kneeling, and the first steps of the morning get loud.
- Diagnosis
An X-ray tells the truth
Standing X-rays show the cartilage gap; "bone-on-bone" means the cushion is gone in at least one part of the joint.
- First moves
Everything short of surgery
Activity changes, strengthening with our therapy team, anti-inflammatories, injections. Done right, these buy some knees years — and we do them right, in-house.
- The line
When surgery becomes appropriate
Pain that interrupts sleep, life shrinking despite conservative care, bone-on-bone imaging, and a patient who's decided the trade no longer works. All four, honestly assessed.
- The surgery
What actually happens
About two hours. Most of ours are robotic-assisted — a CT scan builds a 3D plan and the robot helps your surgeon place the implant to the millimeter. The surgeon does the surgery; the robot does the measuring. Many patients go home the same day from our own surgery center.
- Recovery
Walking day one, life by spring
Steps the day of surgery. Therapy with our own team — same building, same chart. Driving and errands around weeks 4–6, golf swings by month 3, full speed for most by month 6. Full week-by-week timeline below.
Why patients choose Sterling Ridge for this
Twenty-one years in Montgomery County. Fellowship-trained joint surgeons who do this every week, a surgery center of our own at Woodforest — where the facility costs run meaningfully below a hospital stay — and a 38-person rehab team that starts your recovery down the hall from the operating room. One team, one chart, one plan, from "should I?" to "look what I did."
And the part that matters most: we'll tell you if the answer is no. About a third of consults leave without a surgery date — with a real plan instead. That honesty is why the other two-thirds trust us with the yes.
What does it cost?
The question everyone Googles at midnight and almost nobody answers. Nationally, an in-network knee replacement bills between $30,000 and $60,000 — most of it facility and implant costs. What you pay depends on your insurance and where the surgery happens, and both work in your favor here: we're in-network with major plans (Aetna, Blue Cross Blue Shield, Cigna, Medicare, United Healthcare), and our outpatient center typically carries meaningfully lower facility costs than a hospital. Our team verifies your benefits and gives you a real estimate before you decide anything.
The proof
One of our own surgeons, Dr. Bill Hayes, has been through it: he had a knee replacement, filmed it, and rehabbed it with the same team that will rehab you. When someone on your care team can describe the second week of recovery from memory, the conversation is different.
The week-by-week recovery timeline
- Day 0–1
Up and moving
Most patients stand and take steps the day of surgery. Many go home the same day.
- Weeks 1–2
Protect and activate
Home exercises, swelling control, first in-clinic therapy visits. The walker starts collecting dust.
- Weeks 3–6
Range and strength
Bending milestones, strength work, walking without support. This is where showing up to therapy pays.
- Months 2–3
Back to life
Driving, errands, golf swings on the range. Most patients say they wish they'd done it sooner.
- Month 6+
The comeback
Full activity for most patients — and modern implants commonly last 15–20+ years.
Common questions
How long does a knee replacement last?
Modern implants commonly last 15–20 years or more; registry data shows a large majority still functioning at 20 years. Full answer →
When can I drive again?
Most patients: weeks 4–6 — sooner for a left knee with an automatic. The real gates are being off narcotics and passing the emergency-stop test. Full answer →
Am I too young — or too old?
There's no magic age; there's a magic question — how much life is the knee costing you? We replace knees for patients in their 40s and their 80s. Health, not birthday, drives the decision.
Do I have to stay in a hospital?
Increasingly, no. Qualified patients have surgery at our outpatient center at Woodforest and sleep in their own bed that night. Your surgeon will tell you honestly which setting is right for you.
What if I've already had a replacement that's failing?
Revision surgery is its own specialty, and we perform it — including complex cases. Bring your records; we'll tell you what's possible.
Dr. Flowers replaced my knee today. Everything was flawless from beginning to end.— Chris Ryman · Google review · knee replacement
Patients come to us from across the county — Conroe and Lake Conroe, Willis, Magnolia, The Woodlands, and Spring — because the surgeon, the surgery center, and rehab share one campus.
