MAKO Surgical Corp. Showcases Pioneering MAKOplasty(R) Treatment Options for
Total Hip Replacement and Partial Knee Resurfacing Surgeries at AAOS 2013
Annual Meeting

Innovative Procedure Uses Robotic Arm Tactile Technology to Assist Surgeons in
Achieving a New Level of Accuracy

CHICAGO, March 18, 2013 (GLOBE NEWSWIRE) -- MAKO Surgical Corp. (Nasdaq:MAKO),
the leader in robotic arm assisted partial knee and total hip arthroplasty
worldwide, today announced that it will showcase its MAKOplasty^® Total Hip
Arthroplasty (THA) and Partial Knee Resurfacing applications at the American
Academy of Orthopaedic Surgeons 2013 Annual Meeting (AAOS), March 20-23 at
McCormick Place in Chicago. During the meeting, orthopedic surgeons will
deliver presentations and provide hands-on demonstrations in MAKO's booth

MAKOplasty THA is the company's latest application for its RIO^® Robotic Arm
Interactive Orthopedic System, which will be highlighted by the company during
the meeting. The RIO system overcomes limitations of conventional arthroplasty
surgeries by providing auditory, visual and tactile guidance that, when
integrated with the touch and feel of the surgeon's skilled hand, provides
consistently reproducible precision in total hip and partial knee surgeries.
MAKO's robotic arm assisted THA may result in a reduction in complications
associated with conventional hip replacement surgery.

"With total hip replacement using MAKO robotic-arm assistance, I am a better
surgeon because I perform 95 percent of my operations with the implants always
in the correct position," said Lawrence Dorr, M.D., clinical professor of
orthopedics at Keck School of Medicine at University of Southern California in
Los Angeles. "This is better than the Harvard data, which showed 47 percent of
the implants in the correct position^1. Even in my own practice, the MAKO
robotic-arm assistance provides me with greater precision compared to when I
perform the hip replacement using my experience only. Every patient who comes
to me expects me to give him or her a precise operation. My consistent results
allow me to fulfill the trust the patient puts in me," said Dr. Dorr.

"Knowing I have an accurate hip reconstruction gives me confidence I have
minimized the risks for impingement and its consequent complications of
dislocation, pain and accelerated wear. I also believe I have optimized the
chance for durability of the hip replacement of 30 years," continued Dr. Dorr.

Hip replacement with MAKO's robotic-arm assistance builds upon the proven
benefits of MAKOplasty Partial Knee Resurfacing, developed as an advanced
treatment option designed to relieve pain for adults living with early to
mid-stage osteoarthritis that has not yet spread to all three compartments of
the knee. The use of the RIO system in MAKOplasty partial knee resurfacing
leads to implant component placement that is two to three times more accurate
than manual techniques^2. Studies also show that patients with bicompartmental
MAKOplasty have improved function over those with total knee replacement
surgery, and that these MAKOplasty patients demonstrate better post-operative
range of motion and quadriceps strength compared to total knee arthroplasty^3.

"The MAKOplasty procedure with the RIO system for THA and partial knee
resurfacing not only improves accuracy and reproducibility in surgery, it
improves my patients' recovery," said Robert C. Marchand, M.D., a partner at
South County Orthopedics in Wakefield, R.I., and one of the presenters in
MAKO's booth during the AAOS 2013 Annual Meeting. "With partial knee
resurfacing for example, I am able to use the RIO system to create an
anatomical model of the patient's knee and develop a patient specific plan for
optimal implant positioning based on the patient's individual anatomy. The RIO
provides feedback and guidance, thereby preventing me from removing bone form
outside the specified plan, and it allows for accurate implant placement. Our
patients recover more quickly compared to conventional techniques and their
post-operative range of motion is improved as well."

Additional studies describing the clinical success using MAKO's RIO system and
its RESTORIS^® family of implants when performing MAKOplasty procedures are
beginning to appear in peer-reviewed journals, and a body of growing clinical
data continues to be presented at academic meetings worldwide. In a recent
oral presentation of a multi-center trial, the authors presented key results
regarding the accuracy of robotic arm cup placement in total hip procedures,
and reported 87 percent were positioned in an acceptable range. This compares
favorably to data from a recently published Massachusetts General Hospital
(MGH) study, which evaluated 1,823 hips receiving manual total hip
arthroplasty, which reported 47 percent of cups were placed in an acceptable
rage. Mal-positioning of acetabular cups in conventional hip replacement
surgery may lead to impingement and implant wear that can cause dislocation^4.
Nearly 300,000 primary hip replacement surgeries are performed annually in the
United States using conventional technique.

Another multi-center study of MAKOplasty partial knee cases using RESTORIS MCK
onlay medial unicompartmental implants, found very low two year post-operative
revision rates of 0.4 percent, compared to two year revision rates reported at
4.0 percent and 4.4 percent respectively in the Swedish and Australian

As of December 31, 2012, approximately 23,000 MAKOplasty procedures have been
performed worldwide.
