Abington Memorial Hospital Among First in the Region Offering MAKOplasty® Partial Knee Resurfacing

Minimally invasive procedure for early to mid-stage osteoarthritis may provide quicker recovery and more natural feeling knee post-surgery

ABINGTON, PA (February 16, 2015) – Abington Health’s Orthopaedic and Spine Institute announced today that it is now offering MAKOplasty® partial knee resurfacing, at Abington Memorial Hospital.  This minimally-invasive treatment option is for adults living with early to mid-stage osteoarthritis which has not yet progressed to all three compartments of the knee.

MAKOplasty is less invasive than traditional total knee surgery and is performed using RIO,® a highly advanced, surgeon-controlled robotic arm system. Abington Memorial Hospital is one of the first hospitals in the region to acquire this orthopaedic robot.

MAKOplasty potentially offers the following benefits as compared to total knee surgery:

  • Reduced pain
  • Minimal hospitalization
  • More rapid recovery
  • Less implant wear and loosening
  • Smaller scar
  • Better motion and a more natural feeling knee

“MAKOplasty allows us to treat patients with knee osteoarthritis at earlier stages and with greater precision, said Andrew Star, M.D., medical director, Abington Health's Orthopaedic & Spine Institute. “Because it is less invasive and preserves more of the patient’s natural knee, the goal is for patients to have relief from their pain, gain back their knee motion and return to their daily activities.”

The RIO® system enables the surgeon to complete a patient specific pre-surgical plan that details the technique for bone preparation and customized implant positioning using a pre-operative CT scan of the patient’s own knee.  During the procedure, the system creates a three-dimensional, virtual view of the patient’s bone surface and correlates the image to the pre-programmed surgical plan.  As the surgeon uses the robotic arm, its tactile, auditory and visual feedback limits the bone preparation to the diseased areas and provides for real time adjustments and more optimal implant positioning and placement for each individual patient.  

“Precision is key in planning and performing partial knee surgeries,” said Star. “A good outcome requires that the implants be aligned and positioned just right.”  Obtaining this technology is a natural progression of a 13-year commitment facilitating minimally invasive joint surgery.

The opportunity for early intervention is important as osteoarthritis is the most common form of arthritis and a leading cause of disability worldwide, according to the American Academy of Orthopaedic Surgeons.  Candidates for this surgery are usually active adults between the ages of 45 and 65 years old.  Since healthy bone is preserved, patients who undergo the partial replacement may be able to delay total knee replacement until later in life, should it become necessary.

A long-standing leader in minimally invasive procedures, the Orthopaedic and Spine Institute consistently assesses its programs’ processes and offerings to ensure that the very best patient experience is at the center of every decision, said Star. As a result, our patient satisfaction scores are 97 percent for our joint replacement program.
