ORLANDO, Fla. — All-polyethylene fixed-bearing, modular metal-backed fixed-bearing and mobile-bearing total knee arthroplasties showed similar durability, range of motion and function at 10-year follow-up, according to a study presented at the American Academy of Orthopaedic Surgeons Annual Meeting, here.
“We found at 10 years all three groups in this study were reliable, reproducible and durable in alleviating pain and improving function,” Matthew P. Abdel, MD, said.

“Foremost looking at 10-year survivorship free of all cause revision … in the three groups there was no significant differences between them with the rate being approximately 96%,” Abdel said.
He also noted a range of motion of approximately 110° in all three groups with no statistically significant difference, as well as no significant difference in patient function as assessed by the Knee Society Score.
“Finally, we looked at patellar tilt and found no significant difference between the three groups at 10 years,” Abdel said. – by Casey Tingle
