Re:   Registration Statement on Form S-8

Ladies and Gentlemen:

We have acted as special counsel to OrthoPediatrics Corp., a Delaware corporation (the “Corporation”), in connection with the Registration Statement on Form S-8 (together with all exhibits thereto, the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”), relating to the registration under the Securities Act of 1933, as amended (the “Securities Act”), of up to 1,629,000 shares (the “Shares”) of common stock, $0.00025 par value per share, of the Corporation, issuable under the OrthoPediatrics Corp. 2024 Incentive Award Plan (the “Plan”).

For purposes of the opinions contained herein, we have examined and relied upon the originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate records, certificates of public officials, and other instruments as we have deemed necessary. As to any facts material to our opinion which we did not independently establish or verify, we have relied upon oral and written representations of officers and representatives of the Corporation and certificates of public officials and officers and representatives of the Corporation. In our examination, we have assumed with respect to all documents examined by us the genuineness of all signatures, the authenticity of all documents submitted to us as originals, and the conformity to the originals of all documents submitted to us as certified, conformed, photostatic, or telefacsimile copies. We also have assumed with respect to all documents examined by us which contained facsimile signatures that such signatures were the original signature of the party and have the same force and effect as an original signature.

Based on and subject to the foregoing, and subject to the qualifications, assumptions, and limitations stated herein, we are of the opinion that the Shares have been duly authorized and, when issued by the Corporation in accordance with the Plan, will be validly issued, fully paid, and nonassessable.

The foregoing opinions are limited to the Federal laws of the United States and the laws of the State of Delaware as in effect on the date hereof, and we are expressing no opinion as to the effect of the laws of any other jurisdiction.
