Research & Publications

Research Summary

Dr. Freiberg participates in basic research and clinical studies that are related to the long-term durability of hip and knee replacements. His areas of focus include material testing and development related to bearing surfaces, mechanisms of wear, and modulating bone ingrowth.

Dr. Freiberg utilizes specialized robotics systems to study the kinematics of unicondylar and total knee replacements with special emphasis on maximizing range of motion. In other studies, Dr. Freiberg's team uses wear simulators to evaluate new materials and potential failure mechanisms. His other studies include new methods of minimally invasive and computer assisted arthroplasty of the hip and knee.
