Study 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.Check my eligibility
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.See study design
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

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Does this research project restrict volunteers to those over 55 years old?

"According to the inclusion criteria for this particular trial, eligible patients must be aged 18 to 70. However, there are 39 other trials that cater to those under 18 and 727 clinical trials for patients above 65."

Answered by AI

To whom is this clinical trial open?

"Up to 77 patients that have knee pain, are aged 18-70, and meet the following requirements can participate in this trial: those who are awaiting a total knee replacement and are candidates for a bi-cruciate retaining prosthesis, those with disabling bicompartmental gonarthrosis despite conservative treatment attempts, coronal knee malalignment of 10 degrees or less, adequate preoperative range of motion (maximum flexum of 10 degrees and ability to flex greater than 90 degrees), and those with enough intraoperative knee exposure to allow preservation of both cruciate ligaments."

Answered by AI

Are patients being actively recruited for this experiment right now?

"The clinical trial in question is no longer active, based on the information available fromclinicaltrials.gov. This study was first posted on November 1st, 2011 and was last updated on July 19th, 2022. There are 764 other trials currently underway that are actively recruiting patients."
