Postural sway in single-limb and bilateral quiet standing after unilateral total knee arthroplasty

Highlights • 30% of subjects with TKA were unable to perform 20 s single-limb stance on any leg. • Single-limb postural sway was similar in all subjects able to stand on one leg. • Ability to stand on one leg did not affect postural sway in bilateral standing. • Older age, higher BMI, and quadriceps...

Zusammenfassung:	Highlights • 30% of subjects with TKA were unable to perform 20 s single-limb stance on any leg. • Single-limb postural sway was similar in all subjects able to stand on one leg. • Ability to stand on one leg did not affect postural sway in bilateral standing. • Older age, higher BMI, and quadriceps weakness predicted failure to stand on one leg. • Physical capacity rather than TKA appears to predict ability to stand on one leg.
