Objective The objective of this study was to determine the correlations between objective performance-based physical function, self-reported physical function, quality of life, and gait function at 1 month after unilateral total knee arthroplasty (TKA).

Design Cross-sectional data from 195 patients who underwent unilateral primary TKA were analyzed. The isometric knee extensor and flexor strength of both knees, gait parameters, 6 minute walk test (6MWT), timed up-and-go (TUG) test, timed stair climbing test (SCT), knee flexion and extension range of motion (ROM) of surgical knee, Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) pain, stiffness, and functional levels, EuroQol five-dimensions (EQ-5D) questionnaire and visual analog scale (VAS) for knee pain were assessed.

Results In bivariate analyses, both postoperative gait speed and gait endurance hadsignificant positive correlations with postoperative peak torque (PT) of the extensor and flexor of both knees, cadence, stride length, and significant negative correlation with TUG, SCT-ascent, SCT-descent, VAS, WOMAC pain, stiffness, and function levels.In the linear regression analyses, postoperative PT of the extensors of both knees and VAS for knee pain were factors correlated with postoperative gait speed and gait endurance.

Conclusion Quadriceps muscle strength of both knees and knee pain were important factors correlated with gait function early after TKA.
