Prospective analysis identifies preoperative muscle strength as a predictor of functional outcomes following THA, implying its importance in recovery assessment.
Key Points
The aim was to determine how preoperative hip abductor muscle strength predicts functional recovery outcomes post-THA.
Prospective analysis of 184 patients undergoing THA between 2022 and 2023
Linear mixed-effects models assessed the relationship between muscle strength and postoperative outcomes
Outcome measures included HOOS-JR and VR-12 scores at 12-month follow-up.
Greater preoperative hip abductor strength associated with higher HOOS-JR scores (β = 3.58, 95% CI 0.48 to 6.68; P = 0.024)
Increased odds of achieving MCID (OR 9.0 per 5-kg increase; P = 0.044)
Lower odds of not reaching PASS (OR 0.79 per 0.01-unit increase, 95% CI 0.59 to 1.00; P = 0.048)
