Summary
Total knee arthroplasty (TKA) improved gait speed, stride length, and reduced knee pain in patients with knee osteoarthritis (KOA). AI-powered gait analysis effectively quantifies these early postoperative improvements, demonstrating enhanced limb support and coordinated movement.
Area of Science:
- Orthopedic Surgery
- Biomechanical Engineering
- Artificial Intelligence in Healthcare
Context:
- Knee osteoarthritis (KOA) significantly impairs mobility and quality of life.
- Total knee arthroplasty (TKA) is a common surgical intervention for advanced KOA.
- Early postoperative gait assessment is crucial for understanding recovery and optimizing outcomes.
Purpose:
- To investigate early postoperative gait characteristics and clinical outcomes following TKA.
- To evaluate the effectiveness of AI-based gait analysis in quantifying TKA-related changes.
- To correlate gait parameters with clinical improvements in KOA patients post-TKA.
Summary:
- 26 KOA patients underwent TKA, with gait analyzed pre- and post-operatively (6 weeks) using AI (OpenPose).
- Significant improvements were observed in WOMAC scores (pain/function) and KSS.
- Gait speed, stride length, and frequency increased, while lower limb support time and active knee flexion angle decreased post-TKA.
Impact:
- AI-driven gait analysis provides a safe and effective method for quantitative assessment of TKA recovery.
- TKA effectively alleviates knee pain and enhances lower limb function and support.
- Post-TKA patients exhibit improved gait parameters and more coordinated lower limb movement.
