Abstract
[Purpose] This study examined the relationships of physical function and trunk functional evaluation before and after total knee arthroplasty (TKA). [Subjects] Thirty total knee arthroplasty patients. [Methods] The Trunk Righting Test (TRT) and knee extensor strength, single stepladder position time, step test (ST), Timed up and go test (TUG), 5-times chair-standing test (SS-5), 30-s chair-standing test (CS-30) were conducted. [Results] Significant correlations were found between the pre-TKA operated side TRT and post-TKA TUG, and between post-TKA operated side TRT and TUG, CS-30, SS-5, and post-TKA operated side ST. [Conclusion] Pre-TKA operated side TRT and post-TKA TUG are related, and post-TKA operated side TRT is associated with most post-operative physical functions.
