Clinical trial of a new knee replacement implant published
Completed
January 26, 2024
Arthroplasty Research team published the results of a trial look at an enhanced fixation version of a tibial (shinbone) implant during knee replacement compared to a standard tibial implant.
“The new implant design includes “pockets” in the bottom of the tibial component for better bonding to bone cement, “ according to Dr. Christiaan Righolt, Director of Clinical Research at Concordia.
“We used radiostereometric analysis (radiostereometric-analysis-and-clinical-outcomes) to compare the stability of these implants and showed that both performed well; the implants barely moved during the first two years of use” he said.
This typically means there is a low long-term risk of painful loosening for the patients using these implants.
- Impact: This shows the new design performs as well as the old design
- PROMs were similar between both groups, this includes satisfaction, pain, and functional improvements.
- Study size: 50 patients
- Study location: Between Winnipeg and London, ON
- Study duration: Followed patients for 2 years.
- Principal Investigator, Dr. Thomas R. Turgeon.
The team thanks everyone who participated in this study with us.
