Clinical Trial Summary

This study titled "Does Personalised Soft Tissue Balance Data Improve Outcomes in Patients Undergoing Medially Stabilised Arthroplasty? A Prospective, Randomised Study Investigating the Clinical Utility of the NextAR navigation system (NextAR)" is a randomised, single blinded, prospective cohort study with the primary aim determine the clinical utility of the NextAR system data in providing soft tissue balance patterns to enable prosthesis implants to resemble more native knee alignment.


Clinical Trial Description

This study titled "Does Personalised Soft Tissue Balance Data Improve Outcomes in Patients Undergoing Medially Stabilised Arthroplasty? A Prospective, Randomised Study Investigating the Clinical Utility of the NextAR navigation system (NextAR)" is a randomised, single blinded, prospective cohort study with the primary aim determine the clinical utility of the NextAR system data in providing soft tissue balance patterns to enable prosthesis implants to resemble more native knee alignment. The aims of this study are: - To determine the clinical utility of the NextAR system data in providing soft tissue balance patterns to enable prosthesis implants to resemble more native knee alignment - To determine whether NextAR system data contributes to improving patient outcomes and knee kinematics following TKR surgery, by providing greater flexion range that is equivalent to native knee motion. - To assess clinical outcomes measured by standardised assessments, including radiographic evidence, the Forgotten Joint Score (FJS), the Oxford Knee Score (OKS), International Knee Documentation Committee (IKDC) and European Quality of Life Five Dimensions - Five Levels (EQ5D-5L) questionnaires. - Determining the kinematics of the replaced knee as measured by 3D gait analysis. According to study protocol, clinical evaluation is performed preoperatively and postoperatively at 6 weeks, 6 months, 1, and 2 years with the use of the Forgotten Joint Score (FJS), Oxford Knee Score (OKS), International Knee Documentation Committee (IKDC) and European Quality of Life Five Dimensions - Five Levels (EQ5D-5L). CT scan is performed preoperatively and at 6-weeks after surgery, while X-ray assessment is performed at baseline and at the 1-year follow up. ;
