ARTHROCARE REPORTS FOURTH QUARTER AND

ANNUAL 2009 FINANCIAL RESULTS

Austin, Texas — March 15, 2010 — ArthroCare Corp. (NASDAQ: ARTC), a leader in developing state-of-the-art, minimally invasive surgical products, announced its financial results for the fourth quarter and year ended December 31, 2009 as follows:

FOURTH QUARTER 2009

·Fourth quarter 2009 total revenue of $92.5 million

·Product margin of 71.0 percent

·Operating income of $10.7 million

·Net income applicable to common stockholders of $7.1 million, or $0.21 per diluted share

FULL YEAR 2009

·Total 2009 revenue of $331.6 million

·Product margin of 70.5 percent

·Operating loss $0.7 million

·Net loss applicable to common stockholders of $33.8 million, or ($1.26) per share

·Repaid outstanding credit agreement

“We finished 2009 with a satisfying fourth quarter, which included good revenue development, improved product margin and better profitability.  The performance of our core Sports Medicine and ENT businesses was solid.  Our focus now is to deliver on our 2010 performance targets, which includes a commitment to growth, profitability, and cash flow improvements,” noted David Fitzgerald, President and Chief Executive Officer.

REVENUE

Total revenue for the fourth quarter of 2009 was $92.5 million, compared to $80.7 million for the fourth quarter of 2008.  Product sales increased in both the Sports Medicine and ENT businesses. Royalty revenue for the fourth quarter of 2009 included a lump sum $2.5 million royalty settlement received.

Total revenue for 2009 was $331.6 million, compared to $317.7 million for 2008.  Product sales increased in both the Sports Medicine and ENT businesses. Royalty revenue for 2009 was

comparatively higher than in 2008 and was impacted by lump sum settlements received in both 2009 and 2008 of $2.5 million and $1.9 million, respectively.

Product sales were affected by changes in foreign exchange rates used to translate foreign currency sales from international markets to the Company’s U.S. dollar reporting currency.  These changes in exchange rates increased the U.S. dollar reported value of International product sales by $2.0 million for the fourth quarter of 2009 and decreased the U.S. dollar reported value of International product sales by $5.0 million for the year ended December 31, 2009 when compared to the same periods of 2008.

PRODUCT MARGIN

Product margin was 71.0 percent and 63.8 percent for the fourth quarters of 2009 and 2008, respectively.  Product margin was 70.5 percent and 68.7 percent for the year ended December 31, 2009 and 2008, respectively.  Product margin in the fourth quarter of 2008 was negatively impacted by higher excess and obsolescence reserves recorded in 2008 to reduce the carrying value of inventory, partially offset by higher royalties costs incurred in 2009 due to the arbitration ruling involving Gyrus and Ethicon.

INCOME (LOSS) FROM OPERATIONS

Income from operations for the fourth quarter of 2009 was $10.7 million compared to a loss from operations of $28.7 million for the same period in 2008. The improvement in operating results was the result of higher revenue combined with improved gross product margin and lower operating expenses. The loss from operations in the fourth quarter of 2008 includes an $18.9 million goodwill impairment charge recorded related to the Company’s Spine business as well as an additional $4.4 million in investigation and restatement related expenses above what was incurred in the fourth quarter of 2009.

For 2009, the Company had a loss from operations of $0.7 million compared to a loss from operations of $34.0 million for the full year 2008. The improvement in operating results was the result of higher revenue combined with improved gross product margin and lower operating expenses. Operating expenses for 2008 included an $18.9 million impairment charge for goodwill related to the Company’s Spine business and $15.1 million accrued in connection with the panel’s final order in the arbitration matter involving Gyrus and Ethicon.

NET INCOME (LOSS) APPLICABLE TO COMMON STOCKHOLDERS

In the three and twelve months ended December 31, 2009, the Company recorded charges of $0.8 million and $28.0 million, respectively, related to its Series A Redeemable Convertible 3% Preferred Stock issued on September 1, 2009. After these charges, fourth quarter 2009 net income applicable to common stockholders was $7.1 million, or $0.21 per diluted share, compared to a net loss of $29.2 million, or ($1.10) per share, for the fourth quarter of 2008.

For the year ended December 31, 2009, the net loss applicable to common stockholders was $33.8 million, or ($1.26) per share, compared to a loss for the year ended December 31, 2008 of $35.0 million, or ($1.32) per share.

BALANCE SHEET

Cash, cash equivalents, restricted cash equivalents, and investments increased $19.4 million to $57.4 million as of December 31, 2009 from $38.0 million at December 31, 2008.

Cash flows provided by operating activities for the year ended December 31, 2009 was $19.5 million compared to $32.0 million for the year ended December 31, 2008.  Operating cash flow in 2009 was impacted by investigation and restatement related costs, the payment of the settlement related to the arbitration matter with Gyrus and Ethicon referenced above, and insurance settlement payments. The Company continues to focus on working capital efficiency, process improvements, and cash conversion, which has had a favorable impact on cash flows from operations in 2009. Inventory balances decreased approximately $7.8 million, or 13.8 percent, from December 31, 2008.

REVISION OF PRIOR PERIOD FINANCIAL STATEMENTS

During the fourth quarter of 2009, the Company identified an error related to returns of consigned Sports Medicine inventory that were originally processed and recorded in 2008 and an error related to the translation of foreign currencies into U.S. dollars for certain subsidiaries.  The Company assessed the materiality of these errors for the year ended December 31, 2008 and concluded that the errors were not material to the year ended December 31, 2008. However, the Company concluded that the errors were material to the year ended December 31, 2009, principally because the errors would have overstated the growth rate of our Sports Medicine business unit for the three-month period ended December 31, 2009 when compared to the same period in 2008. Thus, the 2008 financial statements filed with the 2009 Form 10-K, have been revised to correct for these immaterial errors. The corrections resulted in a $3.6 million increase in Sports Medicine product sales in the Americas, a $3.6 million increase in gross profit, a $3.9 million increase in foreign exchange loss and a $0.1 million increase to income tax benefit, resulting in a $0.3 million increase to net loss ($0.01 per share) in the consolidated statement of operations for the year ended December 31, 2008. Associated adjustments were also made to the consolidated balance sheet for the year ended December 31, 2008 and on the consolidated statement of cash flows for the year ended December 31, 2008. All 2008 financial information contained in this release has been revised to correct these immaterial errors.

ArthroCare will hold a conference call with the financial community to present these results at 8:30 a.m. ET/5:30 a.m. PT on Tuesday, March 16, 2010. A live and on-demand webcast of the call will be available on ArthroCare’s Web site at www.arthrocare.com.  A telephonic replay of the conference call can be accessed by dialing 800-633-8284 and entering pass code number 21463178.  The replay will remain available through March 30, 2010.
