Abstract
Objective:
Following total knee arthroplasty (TKA), the ability to weight bear symmetrically during the sit-to-stand (STS) task provides important information regarding altered movement patterns. Despite this, comprehensive recovery curves and validity data for STS weight-bearing symmetry (WBS) are lacking in the TKA population. Our study aimed to (i)develop recovery curves with reference ranges, (ii) identify the correlates of standard and constrained STS WBS, and (iii) evaluate their predictive validity with gait speed.
Design:
We performed a retrospective longitudinal study of 706 patients with primary unilateral TKA. Monthly, for 4 months post-surgery, STS WBS, knee pain, knee range-of-motion, quadriceps strength, and gait speed were quantified.
Results:
Standard and constrained STS WBS measures improved nonlinearly over time. Standard STS (sSTS) WBS was most strongly associated with bilateral quadriceps strength whilst constrained STS (cSTS) WBS was most strongly associated with ipsilateral quadriceps strength. Knee range-of-motion and contralateral knee pain were additional correlates. Both sSTS and cSTS WBS were independently and nonlinearly associated with gait speed in multivariable models.
Conclusion:
Our study provided recovery curves and validity data to support routine clinical measurement of STS WBS in TKA. Our results also indicate that cSTS may promote greater use of the operated limb than sSTS.
