It's been a tough summer for robotic orthopedics specialist MAKO Surgical (Nasdaq: MAKO). The stock plunged headlong when the company reported soft results in the first quarter. Management poured salt on that fresh wound in July by pre-announcing another weak slate of results, and shares crashed again. MAKO blamed a spate of delayed sales for this particular miss but didn't back that statement up with strong guidance for the third quarter, so I took the stock off my list of bullish CAPScalls.

Today's 10% overnight share-price jump might make you think that everything is all right, but if so, you're not looking hard enough. Current prices just under $13 per share remain a far cry from the $25 seen in early July, not to mention $40 back in May. The wheels are coming off this bandwagon.

Analysts adjusted their targets en masse based on MAKO's mid-quarter update, and the company managed to beat the lowered earnings consensus in last night's complete second-quarter report. MAKO reported a non-GAAP net loss of $0.20 per share, one penny better than the updated Street view. Sales, of course, landed exactly where everyone expected them to at $23.7 million.

This stock used to be a concentrated growth potion. Year-over-year sales growth of 27% might seem like an intact growth story, but that's drastically lower than last Quarter's 51% revenue jump -- which in turn was a disappointment on the heels of even faster increases.

CEO Maurice Ferre remains undaunted, pointing us toward the growth potential he sees for the next five to 10 years. In his defense, MAKO may be bleeding cash but has the debt-free balance sheet to reach for the stars just a little while longer. The question is, can MAKO restart its stalled growth engines before the financial safety net breaks down?

To overcome the sudden slack in the growth line, MAKO hired an as-yet unidentified executive from fellow robotic surgery specialist Intuitive Surgical (Nasdaq: ISRG) and is working him hard in meetings with interested hospitals. I prefer investing directly in Intuitive Surgical's proven operations rather than hoping that its success will rub off on MAKO's operations.
