An application for exhibit space must be received by AAOS, along with full payment of the booth fee. You can pay by credit card, check, or wire transfer. An application is not considered as received until the payment has also arrived, so paying by credit card will be faster.
If your company has never exhibited at AAOS, you must first complete the Company Review Process before you can apply to exhibit. Once you have completed this process, you do not have to complete it again each year. More information can be found here.
