Between January 2012 and May 2012, a total of 60 patients with
bilateral TKA were included in the study. All patients completed
the study. The two groups were similar in terms of their
demographic characteristics (Table 1). A significant improvement
was observed in all the post-treatment evaluation parameters of
the weighted and non-weighted groups compared to those of the
pre-treatment parameters (Table 2). Before the treatment, the HSS
knee score was the only one significant difference between the
weighted and non-weighted exercise groups in (Table 2).
The post-test adjusted means for variables in both the weighted
and non-weighted exercise groups, using the pre-test results for
both groups as the covariate, are listed in Table 3.
