Dr. Rhett MacNeille combines Mako robotic precision with muscle-sparing surgical techniques — so most patients walk within hours and recover in their own home, not a hospital bed.


Dr. MacNeille is a fellowship-trained total joint replacement surgeon at the Orthopaedic Institute of Southern Illinois, focused exclusively on disorders of the hip and knee — from arthritis care and injections to robotic joint replacement and complex revisions.
Every treatment ladder starts with an accurate diagnosis and every reasonable non-surgical option — surgery is the last rung, not the first.

Mako robotic-assisted, through a quadriceps-sparing midvastus approach, personalized for a natural, kinematic knee.
Knee care
Mako robotic accuracy with a minimally invasive direct superior approach — often with no hip precautions after surgery.
Hip care
When only one compartment is worn, replacing just that part preserves healthy bone and ligaments for a faster recovery.

How they workAlso offering revision hip & knee replacement for joints replaced years ago that have worn or loosened.
Every robotic joint replacement starts with a 3D model of your anatomy. The Mako robotic arm helps execute that plan within a millimeter — for accurate alignment, balanced ligaments, and a joint that feels natural.
Quadriceps-sparing midvastus approach for knees. Direct superior approach for hips — IT band untouched, key stabilizers preserved, and for most patients, no hip precautions.
Multimodal pain control, aspirin-based blood clot prevention, and therapy that starts right away. Most surgery-center patients walk within hours and sleep in their own bed that night.
Watch patients up and walking — some just 10 hours after surgery — and see how Mako robotics plans your joint replacement from your own CT scan.
