Item 2.02 RESULTS OF OPERATIONS AND FINANCIAL CONDITION

     On April 24, 2008, Zimmer Holdings, Inc. (the “Registrant”) reported its results of operations for the quarter ended March 31, 2008. The Registrant’s earnings release is attached as Exhibit 99.1 and the information set forth therein is incorporated herein by reference and constitutes a part of this report.

     The earnings release attached as Exhibit 99.1 includes two types of non-GAAP financial measures. The first type consists of operating performance measures that have been adjusted to exclude certain expenses. The Registrant has presented adjusted net earnings and adjusted diluted EPS for the first quarter 2008 and full year 2008 projected adjusted diluted EPS to exclude the impact of acquisition, integration and other related expenses. The second type of non-GAAP financial measure consists of sales information reported on a constant currency basis which has been calculated by translating actual current and prior-period sales at the same predetermined exchange rate. The translated results are then used to determine year-over-year percentage increases or decreases that exclude the effect of changes in foreign currency exchange rates. These non-GAAP financial measures may not be comparable to similar measures reported by other companies.

     Management believes that the presentation of these non-GAAP financial measures allows investors to more easily compare the Registrant’s performance on a period to period basis. It also aids investors in understanding the operating results of the Registrant absent the specific acquisition-related items detailed above. However, these measures should be considered in addition to, and not as a substitute for, or superior to, other measures prepared in accordance with GAAP.

     All of the non-GAAP financial measures are reconciled to the most directly comparable GAAP financial measure in the press release.

     The Registrant is furnishing the information contained in this report, including the Exhibit, pursuant to Item 2.02 of Form 8-K promulgated by the Securities and Exchange Commission (the “SEC”). This information shall not be deemed to be “filed” with the SEC or incorporated by reference into any other filing with the SEC. By filing this report on Form 8-K and furnishing this information, the Registrant makes no admission as to the materiality of any information in this report, including the Exhibit.
