Loss of Muscle Strength Prior to Knee Replacement: A Question of Anatomic Cross ‐Sectional Area or Specific Strength?

ConclusionPrior to knee replacement, a significant reduction in knee extensor strength appears to occur in women through 2 mechanisms: one driven by pain (loss of specific strength) and one independent of pain (loss of muscle anatomic cross‐sectional area). Men who underwent knee replacement showed significantly reduced levels of extensor anatomic cross‐sectional area, but not significantly lower strength or specific strength.
