FORT LAUDERDALE, Fla., May 7, 2013 (GLOBE NEWSWIRE) -- MAKO Surgical Corp.
(Nasdaq:MAKO), a medical device company that markets its RIO® Robotic Arm
Interactive Orthopedic surgical platform, MAKOplasty® joint specific
applications and proprietary RESTORIS® implants that together enable
orthopedic surgeons to consistently, reproducibly and precisely treat patient
specific osteoarthritic disease, today announced its operating results for the
quarter ended March 31, 2013.

Recent Business Developments

RIO Systems – Five RIO systems were sold during the first quarter to domestic
customers. These five RIO systems bring MAKO's worldwide commercial installed
base of RIO systems to 161 systems and domestic commercial installed base to
156 systems as of March 31, 2013.At the end of the quarter, MAKO had 154
MAKOplasty sites worldwide. In addition, the revenue associated with two
previously deferred international commercial system sales was recognized in
the first quarter as all revenue recognition criteria were satisfied. Six
MAKOplasty THA applications were sold, five of which were sold with the
domestic RIO systems sales during the quarter and one of which was sold as an
upgrade to an existing customer with a knee-only commercial system. As of
March 31, 2013, 102 RIO systems, or 63% of the worldwide commercial installed
base, have the MAKOplasty THA application.

MAKOplasty Procedure Volume – During the first quarter, 2,988 MAKOplasty
procedures were performed, of which 2,861 were performed at domestic sites. Of
the 2,988 procedures, 467 were THA procedures. The 2,988 MAKOplasty procedures
performed represent a 3% increase over the procedures performed in the fourth
quarter of 2012 and a 30% increase over the procedures performed in the first
quarter of 2012. The average monthly utilization per site was 6.6 procedures
during the first quarter of 2013. Through March 31, 2013, approximately 26,000
procedures had been performed since the first procedure in June 2006.

Clinical Research and Marketing – At the 2013 American Academy of Orthopedic
Surgeons in March 2013, Dr. Mark Blyth presented the initial results of the
first 100 patients from the prospective, single center, randomized controlled
trial (RCT) performed at the Glasgow Royal Infirmary with the University
ofStrathclyde. The RCT compares the MAKOplasty unicompartmental knee
arthroplasty performed with MAKO's RESTORIS MCK implants to manually placed
Biomet Oxford® implants. MAKOplasty resulted in significantly lower
post-operative pain from day one to eight weeks post-op and it took eight
weeks for Oxford patients to reach the lower pain levels that MAKOplasty
patients were already reporting after six days. MAKOplasty also demonstrated
higher accuracy in all dimensions measured, with statistically significant
differences in four of the six dimensions. Finally, a significantly higher
percentage of MAKOplasty patients had "Excellent" American Knee Society Scores
at three months.

Patent Infringement Actions – On April 16, 2013, MAKO agreed to settle all
patent infringement actions against Stanmore Implants Worldwide Limited and
affiliated entities. Under a confidential settlement agreement and an asset
purchase agreement between the parties, in exchange for a cash payment to
Stanmore, MAKO withdrew all legal actions against Stanmore and received
Stanmore's robotic business assets and related intellectual property, as well
as Stanmore's agreement to withdraw from robotics.

"The first quarter is typically a slower quarter for MAKO, and our first
quarter results were in line with our expectations," said Maurice R. Ferré,
M.D., President and Chief Executive Officer of MAKO. "The initial results of
our programs designed to drive utilization and system sales are encouraging,
and I remain confident in our outlook for 2013."

2013 First Quarter Financial Review

Revenue was $24.8 million in the first quarter of 2013 compared to $19.6
million in the first quarter of 2012, representing a 26% increase. The
increase in revenue was primarily attributable to the recognition of revenue
of 2,988 MAKOplasty procedures performed, which represents a 30% increase over
the procedures performed in the first quarter of 2012, and an increase in
system revenue and service revenue.

Gross profit for the first quarter of 2013 was $18.3 million compared to a
gross profit of $14.2 million in the same period in 2012. Gross margin for the
first quarter of 2013 was 74%, consisting of a 75% margin on procedure
revenue, a 63% margin on RIO system revenue and an 87% margin on service
revenue.

Operating expenses were $27.2 million in the first quarter of 2013 compared to
$25.9 million in the first quarter of 2012. The increase in operating expenses
was primarily due to an increase in sales, marketing and operations costs
associated with the commercialization of the RIO system, MAKOplasty
applications and RESTORIS implant systems; and an increase in general and
administrative costs as MAKO continued to build infrastructure to support
growth.

Net loss for the three months ended March 31, 2013 was $9.6 million, or
$(0.21) per basic and diluted share, based on average basic and diluted shares
outstanding of 46.8 million. Included in net loss for the first quarter of
2013 was anon-cash and non-operating expense of $661,000 associated with the
change in fair value of a derivative asset related to a credit facility
agreement. This compares to a net loss for the same period in 2012 of $11.7
million, or $(0.28) per basic and diluted share, based on average basic and
diluted shares outstanding of 41.7 million.

Cash, cash equivalents and available-for-sale investments were $71.0 million
as of March 31, 2013 compared to $73.3 million as of December 31, 2012. As of
March 31, 2013, no amounts have been drawn under the credit facility agreement
with affiliates of Deerfield Management Company, L.P.

Outlook

MAKO's 2013 annual guidance of 45 to 48 RIO systems sold and 13,500 to 14,500
MAKOplasty procedures performed remains unchanged.
