An Analysis of Potential Sex Differences in Knee Osteoarthritis

This pilot study will use tissues and fluids that are normally discarded during the course of total knee replacement surgery to investigate potential sex differences in knee osteoarthritis. Basic clinical demographic information will be obtained as well as preoperative functional and pain assessment scores, functional tests, and pressure pain threshold measurement. The purpose of the study will be to investigate if any sex differences can be identified in these tissues and to investigate if there appears to be any relationship between these differences and functional scores and tests.
