Functional Impact at 12 Months Post-op of Posterior Cruciate Ligament Conservation During Robotic-assisted Surgery (MAKO) for Total Knee Replacement.

Evaluation of the Functional Impact at 12 Months Post-op of Posterior Cruciate Ligament Conservation During Robotic-assisted Surgery (MAKO) for Total Knee Replacement. A Randomized, Single-blind, Multicenter, Controlled Superiority Study.

Sponsor

Centre Hospitalier Universitaire de Nīmes

Enrollment

300 participants

Start Date

Oct 10, 2025

Study Type

INTERVENTIONAL

Conditions

Knee Arthroplasty, Total

Summary

Studies have been made on the best way to do knee surgery and whether to conserve the posterior cruciate ligament or not during total knee prosthesis insertion is still under debate. However, most of these studies were made before the introduction of robotic knee surgery. It seems timely to do a study comparing these two surgical techniques: preservation versus removal of the posterior cruciate ligament in knee arthroplasty

Eligibility
