Summary

This trial will compare the clinical and radiological results of patients undergoing total knee replacement surgery according to the type of prosthesis used. It is anticipated that the bicruciate-retaining prosthesis will result in better function of the operated knee than the posterior-stabilized prosthesis.

Who is the study for?
This trial is for people under 70 with severe knee osteoarthritis needing a total knee replacement, who have failed conservative treatments. They must be able to fully extend the knee within 10 degrees and bend it past 90 degrees, have intact cruciate ligaments, less than 10 degrees of knee malalignment, and be capable of undergoing an EOS exam.
What is being tested?
The study compares two types of total knee replacements: bicruciate-retaining (2C) that keeps both cruciate ligaments versus posterior-stabilized (PS), which does not. It's a randomized controlled trial where patients are assigned by chance using sealed envelopes to determine if one results in better function.
What are the potential side effects?
While specific side effects aren't listed here, typical risks include pain at the surgery site, infection, blood clots or deep vein thrombosis (DVT), stiffness or difficulty moving the joint as expected after surgery.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: bicruciate-retaining total knee arthroplastyExperimental Treatment1 Intervention
The prosthesis is minimally constrained and allows the preservation of both cruciate ligaments. All implants are cemented.
Group II: posterior-stabilized total knee arthroplastyActive Control1 Intervention
The prosthesis requires the excision of both cruciate ligaments
