Your donation will continue to help us achieve our mission and make a difference to people's lives. You may donate online, by telephone or by mail. Your gift will enable Operation Walk’s team of health care professionals to return patients with disabling joint disease to a more normal lifestyle. Candidates screened for possible Operation Walk surgery are often confined to a wheel chair, crutches or dependent on someone else just to walk a short distance. The gift of a new hip or knee joint from the Operation Walk team can make a significant difference.
