Dr. Palmer’s practice offers a full array of hip and knee replacement procedures, from primary replacement to complex revision. For primary total hip arthroplasty, Dr. Palmer focuses exclusively on the anterior approach.  He believes the minimally invasive nature of the anterior approach allows patients a quicker recovery and no restrictions after surgery.  For revision hip arthroplasty, he is trained to perform all approaches to the hip to be able to address the problem most effectively.  

Dr. Palmer offers a full spectrum of ligament-preserving and substituting total knee replacement techniques, including unicompartmental knee arthroplasty.  As a specialist, Dr. Palmer is trained to understand the fine details of knee reconstruction, and prefers manual techniques during knee replacement.  However, Dr. Palmer is trained to perform robotic-assisted knee replacements using the Blue Belt NavioTM Surgical System. 

In addition, Dr. Palmer performs joint preservation procedures such as hip and knee arthroscopy when patients may not require a joint replacement.

“I am proud to be a part of OrthoNeuro, which I believe is uniquely positioned in Central Ohio to provide not only high quality but comprehensive musculoskeletal care through many sub-specialties. My sub-specialty training in hip and knee preservation, replacement and reconstruction allows me to provide a customized surgical or non-surgical treatment strategy to my patients.
