Phase 4

Completed

• Conditions: Advanced knee osteoarthritis treatment; total knee arthroplasty; gradually reducing radius; multi-radius femoral component; functional outcomes

• Registration Number: TCTR20221030001
• Lead Sponsor: Faculty of Medicine, Chiang Mai University

Brief Summary

The KOOS score at 6 months postoperatively showed each subscale of symptom 85 vs 85, pain 87 vs 85, activity of daily living 80 vs 81, sport 70 vs 68, and quality of life 81 vs 83 for GR vs MR). The KOOS at 12 months showed subscale of symptom 90 vs 89, pain 90 vs 88, activity of daily living 84 vs 84, sport 80 vs 78, and quality of life 91 vs 90 for GR vs MR). The GR prosthesis design gave more knee motions than did the MR prostheses (34.67 vs 23.67, p 0.001) at 12 months postoperatively.
