MAKO Surgical's (UNKNOWN:UNKNOWN) Q1 results show a smaller loss. For the quarter, revenue was $24.8 million, a notable rise from the $19.6 million in the same period the previous year. The company managed to thin its net loss, which came in at $9.6 million ($0.21 per diluted share) from Q1 2012's shortfall of $11.7 million ($0.28).

MAKO Surgical made most its money by selling five of its Robotic Arm Interactive Orthopedic platforms and reaping the revenue from nearly 3,000 of its MAKOplasty orthopedic surgery procedures.

Analysts had been expecting revenue of $24.4 million and a per-share loss of $0.19.

The company also reiterated its prior guidance. It still expects to sell 45 to 48 RIO Systems this year and anticipates that 13,500-14,500 MAKOplasty procedures will be performed.
