Replace the
knee. Keep the
trength.
Robotic-assisted total knee replacement, planned from your CT scan and executed with sub-millimeter precision. Paired with a quadriceps-sparing technique that preserves the tendon you rely on for stairs, walking, and getting up out of a chair.

Why robotic
precision matters here.
Knee replacement is the most successful operation in orthopedic surgery — but outcomes depend heavily on implant alignment, soft-tissue balance, and how well the implant fits each patient’s anatomy. That’s exactly what robotic assistance is built to optimize.
Before surgery, a CT scan is converted into a personalized 3D model of your knee. From that model, we build a surgical plan that’s specific to your anatomy — implant size, position, alignment, and soft-tissue balance — and we can adjust it intraoperatively based on how your knee actually behaves under tension.
During surgery, the Mako robotic arm enforces that plan. Bone cuts are made within a fraction of a millimeter of the planned position. The implant fits because the bone was prepared to fit it — not the other way around.
This is not autonomous robotic surgery. The surgeon controls every motion. The robot enforces a plan and prevents the kind of small alignment errors that compound into long-term wear.
— What you gain from robotic assistance
01
Personalized to your anatomy
A surgical plan built from your CT, not a template.
02
Better implant alignment
Sub-millimeter accuracy in bone cuts and implant positioning.
03
Real-time soft-tissue balance
The plan adjusts to how your ligaments behave during surgery.
04
Less soft-tissue trauma
Cleaner cuts and a tighter cutting envelope mean less collateral disruption \u2014 patients typically report less early postoperative pain and use fewer opioids in the first weeks.
The quadriceps stays intact.
Traditional knee replacement cuts through the quadriceps tendon to expose the joint. That tendon then has to heal — which is why traditional recovery takes months and stairs feel difficult for far too long. The quadriceps-sparing approach goes around the tendon, not through it.

The implant:
Triathlon.
The Triathlon Knee System is the most widely used total knee implant in the world, with more than two decades of clinical data behind it. Its geometry is designed to replicate the natural motion of the knee — particularly through the deep flexion required for stairs, squatting, and getting in and out of a car.

Recovery,
week by week.
Every patient is different, but here’s the typical arc. Quad-sparing technique combined with robotic precision tends to shorten what used to be a six-month recovery into something much closer to six weeks for the heavy lifting.
DAY 0
Surgery & walking
Procedure takes about 90 minutes. Most patients stand and take a few steps within hours of waking up in recovery.
DAY 1
Home or one night
Many patients go home the same day. Others stay one night. Walking with assistive device, climbing stairs supervised.
WEEK 1–2
Range of motion & PT
Physical therapy starts immediately. Goals are bend, straighten, walk steadily. Most patients transition off walker to a cane in this window.
WEEK 3–6
Stairs & daily life
Because the quad tendon was preserved, stairs come back faster than with a traditional approach. Desk work resumes, walking distances grow.
WEEK 6–12
Strength & activity
Range of motion continues to improve. Patients return to walking long distances, light hiking, biking, and recreational activity.
— LONG TERM
A knee built to last
Modern implants placed with robotic precision are designed for 20+ years of use. Most patients return to the activities they want — and forget they have a replacement.

Frequently asked
questions.
The questions patients ask most often when considering knee replacement. If yours isn’t here, bring it to your consultation.
How is robotic knee replacement different from traditional?
In a traditional knee replacement, bone cuts are guided by physical jigs and the surgeon’s visual judgment. In a robotic-assisted procedure, the cuts are guided by a personalized 3D plan and executed by a robotic arm within a fraction of a millimeter. The surgeon is still in full control — the robot enforces the plan.
Should I have a partial or a total knee?
No. The Mako robotic arm doesn’t operate autonomously. Every motion is controlled by the surgeon. The system enforces the surgical plan — it prevents the kind of small alignment errors that can compound over years — but the operation itself is still surgeon-led from start to finish.
Will I be in the hospital overnight?
No. The Mako robotic arm doesn’t operate autonomously. Every motion is controlled by the surgeon. The system enforces the surgical plan — it prevents the kind of small alignment errors that can compound over years — but the operation itself is still surgeon-led from start to finish.
When can I drive again?
No. The Mako robotic arm doesn’t operate autonomously. Every motion is controlled by the surgeon. The system enforces the surgical plan — it prevents the kind of small alignment errors that can compound over years — but the operation itself is still surgeon-led from start to finish.
How long does the implant last?
No. The Mako robotic arm doesn’t operate autonomously. Every motion is controlled by the surgeon. The system enforces the surgical plan — it prevents the kind of small alignment errors that can compound over years — but the operation itself is still surgeon-led from start to finish.
What activities can I do afterward?
No. The Mako robotic arm doesn’t operate autonomously. Every motion is controlled by the surgeon. The system enforces the surgical plan — it prevents the kind of small alignment errors that can compound over years — but the operation itself is still surgeon-led from start to finish.
