MAKOplasty Knee and Hip Replacement


Revolutionary knee resurfacing and hip replacement technology

Thanks to cutting-edge, surgeon-controlled robotic technology, adult patients considering knee or hip replacement have a minimally-invasive option for treatment that allows for a return to full activity as quickly as possible.

MAKOplasty is a surgical procedure for partial knee or total hip replacement performed using the RIO Robotic Arm Interactive Orthopedic System, which allows the performing surgeon to place an implant exactly, and achieve repeatable results time after time.

Partial Knee Resurfacing

MAKOplasty Partial Knee Resurfacing is a treatment option for adults living with early to mid-stage osteoarthritis that has not yet progressed to all three compartments of the knee. It is less invasive than traditional total knee surgery. A pre-surgical plan is created based on a CT scan of the patient’s own knee, and the surgeon uses the robotic arm during surgery to resurface the diseased portion of the knee, sparing healthy bone and surrounding tissue for a more natural feeling knee. An implant is then secured in the joint to allow the knee to move smoothly again. 

Total Hip Replacement

During MAKOplasty Total Hip Replacement surgery, RIO provides both visualization of the joint and biomechanical data to guide the bone preparation and implant positioning to exactly match the pre-surgical plan. After first preparing the femur (thighbone), the surgeon uses the robotic arm to accurately ream and shape the acetabulum socket in the hip, and then implant the cup at the correct depth and orientation. The surgeon then implants the femoral implant.  MAKOplasty offers the confidence of more accurate cup placement and accurate leg length restoration.

Patient Experience

MAKOplasty typically results in a hospital stay ranging from 1-3 days.  Patients are often able to return to walking a few days following discharge, and able to drive a car within two weeks.  Full function returns shortly thereafter.

David T. Stamer, MD, FAAOS
Orthopaedic Surgeon

Board certified in orthopaedic surgery, Dr. Stamer has been in practice in the Mid-Hudson Valley since 1994. He enjoys both the non-surgical and surgical treatment of most orthopaedic conditions and injuries, including knee and shoulder arthroscopy, fracture care and hip and knee replacement surgery, with a special interest in robotic assisted partial knee and total hip replacement.

Dr. Stamer on MidHudson Regional Hospital: “In all my years as an orthopaedic surgeon, MidHudson Regional Hospital has traditionally been the main center for excellence in the mid-Hudson Valley for both emergency and elective surgery. Their commitment to providing patients access to the latest technology is why I choose to perform my total hip and partial knee replacement surgeries there.”
