Bone Scanning for the Evaluation of Knee Prosthesis

Abstract

Twenty-six knees were scanned after total replacement to evaluate the relationship between bone scan, pain, the presence of a radiolucent line at the bone-cement interface and loosening. A radiolucent line was often accompanied by an increased uptake over the affected condyle, but there was no significant relationship with pain or loosening.

Key words:

• knee arthroplasty
• radioisotope scanning
• radiolucent line
