Quadriceps muscle force magnitude and control in the knee scheduled for arthroplasty versus the contralateral knee: A cross-sectional study in patients with end-stage osteoarthritis

Key Points

• Quadriceps muscle force is significantly different between knees scheduled for arthroplasty and the contralateral knee, indicating imbalances during movement.
• The study observed that patients with end-stage osteoarthritis exhibit less control over muscle force in the affected knee compared to the healthy knee.
• Cross-sectional analysis compared quadriceps strength and control in knees from individuals with severe osteoarthritis undergoing arthroplasty.
• These findings highlight the importance of assessing muscle force before surgery for better rehabilitation strategies post-arthroplasty.
