Knee Joint Biomechanics and Neuromuscular Control During Gait Before and After Total Knee Arthroplasty are Sex-specific

摘要

The future of total knee arthroplasly (TKA) surgery will involve planning that incorporates more patient specific characteristics. Despite known biological, morphological, and functional differences between men and women, there has been little investigation into knee joint biomechanical and neuromuscular differences between men and women with osteoarthritis, and none that have examined sex specific biomechanical and neuromuscular responses to TKA surgery. The objective of this study was to examine sex associated differences in knee kinematics, kinetics and neuromuscular patterns during gait before and after TKA. Fifty two patients with end-stage knee OA (28 women, 24 men) underwent gait and neuromuscular analysis within the week prior to and one year after surgery. A number of sex-specific differences were identified which suggest a different manifestation of end-stage knee OA between the sexes. (C) 2014 Elsevier Inc. All rights reserved.
