Zimmer Holdings Inc. today said its profit shrank 30 percent in the third quarter due to one-time costs and a loss on interest.

The Warsaw, Ind.-based orthopedic implant maker reported a profit of $149.9 million, or 70 cents per share, down from $214.7 million, or 95 cents per share, in the same period a year earlier.

Excluding special items, profit in the latest quarter was 88 cents per share. According to Thomson Reuters, analysts expected profit of 86 cents per share.

“We are pleased that our sales momentum continued to build in the third quarter as we achieved year-over-year constant currency growth in revenues in each of our three geographic segments,” said David Dvorak, Zimmer President and CEO. “Further, we believe we are stabilizing our core knee and hip franchises and establishing a solid foundation for future growth.”

Revenue increased 2 percent, to $975.6 million from $952.2 million as sales of devices used in reconstructive knee surgeries increased. Analysts estimated $953.8 million in revenue.

Zimmer also reported a loss of $4.2 million on interest and other items, compared with a profit of $28.2 million in the year-ago quarter.

Zimmer backed its full-year outlook for profit of $3.85 to $4 per share, with revenue rising 1 to 3 percent excluding the effects of foreign currency exchange rates. The forecast implies revenue of $4.16 billion to $4.24 billion.
