Knee Care

A knee plan built around your anatomy and your goals

From injections and bracing to Mako robotic-assisted partial and total knee replacement.

Options at Every Stage

The full range of knee care

  • Diagnostics — X-ray, CT, and MRI to understand exactly what is causing your pain
  • Non-surgical care — cortisone, gel, and PRP injections; bracing and knee sleeves; physical therapy
  • Partial knee replacement — replace only the worn compartment, preserve your ligaments
  • Total knee replacement — Mako robotic-assisted, quadriceps-sparing, kinematically aligned
  • Revision knee replacement — for knees replaced years ago that have worn or loosened

Dr. MacNeille's Technique

Robotic precision. A kinematic, natural-feeling knee.

Quadriceps-Sparing

Midvastus approach

Instead of cutting the quadriceps tendon, Dr. MacNeille works between muscle fibers — studies show earlier leg control, less early pain, and faster discharge.

Kinematic Alignment

The knee you were born with

Rather than forcing every knee to an artificial average, your implant is aligned to your natural anatomy and ligament tension — the goal is a knee you forget about.

Mako Robotics

Within a millimeter of plan

Published studies show over 91% of Mako bone cuts land within 1 mm of the plan — accuracy that supports balanced ligaments and a natural feel.

What a Knee Replacement Does

From worn joint to new joint

Arthritis wears through the cartilage that lets your knee glide. A knee replacement resurfaces the worn joint — only one compartment for a partial, or the whole surface for a total knee.

An arthritic knee. The cartilage is worn through to bare bone — the source of pain, swelling, and stiffness.

After knee replacement. The worn surfaces are replaced so the joint glides smoothly again.
3D illustration of a partial knee replacement resurfacing only the inner compartment of the knee
Partial knee replacement. When arthritis is limited to one compartment, only that surface is replaced — your ligaments and the rest of the joint are preserved.
