Pat Campbell, PhD

Professor
Director, Implant Retrieval Laboratory
The J. Vernon Luck, Sr, MD Orthopaedic Research Center

Dr. Campbell is the Director of the Implant Retrieval Laboratory of the JVL Orthopaedic Research Center, located at Orthopaedic Institute for Children in downtown LA. She has focused her research on the implant retrieval analysis of joint arthroplasties, with particular emphasis on the biological factors that affect the clinical performance of implants, histological scoring of periprosthetic tissues, and the evaluation of prosthetic joint fixation. More recently, she has conducted implant retrieval studies on retrieved megaprosthesis implants used for limb salvage operations frequently done in pediatric oncology patients. In addition, the clinical evaluation of lumbar and cervical disc replacements and the histology of tissue reactions associated with these devices have become a new area of study.
