ITEM 1. SECURITY AND ISSUES

This statement on Schedule 13D (this "Statement") relates to the Common Stock, par value $.01 per share (the "Common Stock"), of DJO Incorporated, a Delaware corporation (the "Issuer" or the "Company"), the principal executive offices of which are located at 1430 Decision Street, Vista, California 92081.

ITEM 2. IDENTITY AND BACKGROUND

(a) This statement is being filed on behalf of (i) MMI Investments, L.P., a Delaware limited partnership ("MMI Investments") and (ii) MCM Capital Management, LLC, a Delaware limited liability company that is the sole general partner of MMI Investments ("MCM"). MMI Investments and MCM are herein together sometimes called the "Reporting Persons". Set forth on Schedule I, annexed to this Statement and incorporated herein by reference, is the name, business address and present principal occupation or employment, and the name and address of any corporation or other organization in which such occupation or employment is conducted, of each voting member (each of whom is also an executive officer) of MCM as of the date hereof.

(b) The business address of both of the Reporting Persons is 1370 Avenue of the Americas, New York, New York 10019.

(c) MMI Investments is engaged primarily in the business of investing in publicly traded securities. MCM is the sole general partner of MMI Investments and its principal business is investing in publicly traded securities.

(d) Neither of the Reporting Persons nor, to each Reporting Person's knowledge, any individual listed on Schedule I, is required to disclose legal proceedings pursuant to Item 2(d) of Schedule 13D.

(e) Neither of the Reporting Persons nor, to each Reporting Person's knowledge, any individual listed on Schedule I, is required to disclose legal proceedings pursuant to Item 2(e) of Schedule 13D.

(f) To each Reporting Person's knowledge, each of the individuals identified on Schedule I is a citizen of the United States.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

The total purchase price of the 2,212,900 shares of Common Stock (the “Shares”) purchased by MMI Investments was $82,813,445; the source of funds is a combination of MMI's working capital and margin loans. These margin loans were obtained from Bear, Stearns & Co. Inc. and Merrill Lynch & Co. under customary terms and conditions. The entire principal amount of such margin loans remains outstanding as of the date of this Statement.

- Page 5 of 12 -

ITEM 4. PURPOSE OF TRANSACTION

MMI Investments purchased the Shares as part of its investment activities. The Reporting Persons intend to review and evaluate the investment by MMI Investments in the Common Stock of the Issuer on an ongoing basis and may, depending upon their evaluation of the business and prospects of the Issuer, or such other considerations as they may deem relevant, determine to increase, decrease, or dispose of MMI Investments' holdings of Common Stock. As a part of such review and evaluation, the Reporting Persons may communicate with the Issuer's management, directors and other shareholders.

In order to retain its flexibility to determine to increase MMI Investments’ holdings of Common Stock to more than 10% of the outstanding Common Stock of the Issuer, MMI Investments intends to notify the Issuer of its intention to file in the near future a Notification and Report Form under the Hart Scott Rodino Antitrust Improvements Act of 1976, as amended ("HSR Act") and request early termination of the waiting period pursuant to the HSR Act. Upon such filing, the filing of the Issuer’s responsive filing, and the expiration or early termination of the waiting period, the Reporting Persons would be permitted under the HSR Act to purchase additional shares of Common Stock such that the Reporting Persons would hold up to $500 million (subject to adjustment from time to time in accordance with the HSR Act, with the current threshold being $597.9 million) in total market value of Common Stock at the time of such purchase. However, MMI Investments does not currently intend to purchase Common Stock of the Issuer if, as a result of the purchase, it would own more than 14.9% of the outstanding Common Stock (which would have represented a market value of approximately $137 million based on the number of shares outstanding at May 8, 2007 and the closing price on June 21, 2007).

Other than as described in this Item 4, neither Reporting Person, nor, to the knowledge of each Reporting Person, any individuals listed on Schedule I, has any current plan or proposal that relates to or would result in any of the transactions or other matters specified in clauses (a) through (j) of Item 4 of Schedule 13D; provided that the Reporting Persons reserve the right to develop such plans or proposals.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

(a)-(b) Based on 23,557,221 shares of Common Stock outstanding as of May 8, 2007, as reported in the Issuer's Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2007 filed with the SEC on May 10, 2007, the Shares owned by MMI Investments represent approximately 9.4% of the outstanding Common Stock. MMI Investments has the sole power to direct the vote and disposition of such Shares on the date of this Statement. However, by virtue of being the general partner of MMI Investments, MCM may be deemed to be the beneficial owner of the Shares owned by MMI Investments and to have sole power over the voting and disposition of such Shares as a result of its having the sole power to make voting and disposition decisions on behalf of MMI Investments with respect to such Shares.

Except for the Shares owned by MMI Investments, as of the date hereof, neither MCM nor, to MMI Investments' and MCM's knowledge, any of the persons listed on Schedule I, owns any Common Stock of the Issuer or has any right to acquire, directly or indirectly, any beneficial ownership of other Common Stock of the Issuer.

(c) Except for the open market purchases of Common Stock by MMI Investments set forth in Schedule II attached hereto and incorporated herein by reference, there have been no transactions with respect to the Common Stock during the past 60 days by MMI Investments, MCM, or, to either Reporting Person's knowledge, any of the persons listed on Schedule I.

(d) No person other than MMI Investments is known to either Reporting Person to have the right to receive or the power to direct the receipt of dividends from or the proceeds from the sale of, any of the Shares referred to in Item 5(a) above.

(e) Not applicable.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS, OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER

By virtue of being the general partner of MMI Investments, MCM may be deemed to be the beneficial owner of the Shares of the Issuer owned by MMI Investments. Other than as described in Item 3 of this Statement (and the Joint Filing Agreement filed as an Exhibit to this Statement), there are no contracts, arrangements or understandings between the Reporting Persons or between either of the Reporting Persons and any other person with respect to any securities of the Issuer.
