The purpose of this study was to assess the effects of acute joint
effusion on balance in patients with knee osteoarthritis.
DESIGN: Forty-four
female subjects with painful knee osteoarthritis participated in this
single-blind, randomized, controlled clinical trial. All subjects were randomly
assigned to either the injection or the control group. A volume of 20 ml of
normal saline was injected into the knee joint cavity of the test subjects, who
performed static and dynamic balance tests twice before and after joint infusion.
The subjects in the control group performed the same tests without joint
infusion. The outcome variables for static measurement were the mean speeds
(millimeter per second) of the movement of the center of pressure in the
mediolateral and anteroposterior directions and the mean velocity moment (square
millimeter per second) with both eyes opened and eyes closed conditions. For
dynamic measurement, time (second) and distance (millimeter) of the center of
pressure were used. RESULTS: Significant interaction of the balance-test
variables (mean speeds, velocity moment, time, and distance) between the groups
and time (P > 0.05) was not found. There were no significant differences between
the groups in any of the balance-test variables (P > 0.05). CONCLUSIONS: This
study showed that acute joint effusion has no effect on static or dynamic
postural sway in patients with knee osteoarthritis.
