Evaluation of the Tissue Response to a Knee Hemiarthroplasty

摘要

The UniSpacer Knee System is an implant that can be used for the treatment of osteoarthritis of the medial compartment of the knee with no resection of the articulating tissues. Concern has been raised as to whether the implant adversely affects the tissues articulating against it. While our study indicates that osteoarthritis is present, there is no evidence to support that a foreign body reaction has been elicited. Further research is needed to evaluate the potential biochemical and immune responses.
