Board certified by the American Board of Orthopaedic Surgery, Dr. Kaper is a Fellow of the American Academy of Orthopaedic Surgery and a member of the American Association of Hip & Knee Surgeons, Western Orthopaedic Association, and Arizona Medical Association. Dr. Kaper serves as a Clinical Assistant Professor at Midwestern University, Arizona College of Osteopathic Medicine in Glendale, AZ.  Dr. Kaper is also the author of numerous peer-reviewed journal articles as well as a regular presenter at scientific and medical conferences.  As part of his commitment to the advancement of orthopaedic surgery, he is a frequent faculty teacher at national orthopaedic meetings- educating other orthopaedic surgeons in the techniques of Direct Anterior total hip replacement and robotic assisted partial and total knee replacement.

In addition, he is the founder and chairman of the board for Operation Walk International, a 501(c)3 non-for-profit charitable organization.  This organization is dedicated to providing free hip and knee replacement surgery to patients in underdeveloped countries.  Since 2007, Dr. Kaper and his team has traveled to both Antigua, Guatemala and Cuenca, Ecuador- where they have performed over 500 free hip and knee replacement surgeries for  the native population.  Ongoing challenges with developmental hip dysplasia in Ecuador have created the need for highly specialized hip reconstructive surgeries that Dr. Kaper and his team perform with what is known as femoral shortening osteotomies- surgeries that can dramatically change the patient’s ability to walk and live.
