Effectiveness of the Journey Total Knee Arthroplasty Versus Two Standard of Care Total Knee Arthroplasty Prostheses

Comparative Effectiveness of the Journey Total Knee Arthroplasty Relative to Two Standard of Care Total Knee Arthroplasty Prostheses: A Randomized Controlled Trial

The purpose of the study is to determine if knee replacement performed using Journey II implant is different from two other standard-of-care knee replacements using Stryker and Zimmer in terms of knee movements and forces, walking patterns, pain, and function after surgery.

Study Overview

• Status: Recruiting
• Conditions: Osteoarthritis, Knee
• Intervention / Treatment: Device: Journey II; Device: Stryker; Device: Zimmer

Detailed Description

Background

Osteoarthritis is the most prevalent form of arthritis, with weight-bearing joints, particularly the knee commonly affected. Osteoarthritis is a leading cause of mobility disability and is associated with functional loss in adults. Total knee arthroplasty (TKA) is cost-effective and successful for those with end-stage knee osteoarthritis. In 2016/17, about 67,169 TKAs were performed in Canada, an increase of 16% since 2012/13.

Justification

TKA aims to improve joint mechanics as well as knee pain and function. Patients indicate that their primary expectations following TKA are improved pain and walking ability. Most TKA implants are fixed bearing (such as Stryker and Zimmer) with no movement of the implant with knee motion. The Journey II TKA has a medial pivot function that may improve patient outcomes further, by replicating meniscal function. However, this has not yet been proven as it would require more specific measurement of knee kinetics and kinematics such as we propose here.

The outcome of this study will provide information about knee pain, movements (kinematics) and forces (kinetics) and walking patterns after TKA using different implants. Through this study, we should be able to inform future research on rehabilitation protocols to alter knee movements after TKA, while enhancing patients' function and quality of life.

Hypotheses

Primary Hypothesis: We hypothesize that TKA performed using the Smith and Nephew Richards (SNR) Journey II TKA system will be superior to standard TKA prostheses (Stryker Triathlon Total Knee System and Zimmer Persona® The Personalized Knee) in terms of knee biomechanics (knee kinematics and kinetics) and spatio-temporal gait parameters at 1-year post-TKA using the Computer-Assisted Rehabilitation ENvironment (CAREN).

Secondary Hypothesis: We hypothesize that the Smith and Nephew Richards (SNR) Journey II TKA will provide increased improvement from preoperative levels in pain and function in comparison to standard TKA prostheses.

Objectives

Primary Objective: The primary objective of this randomized, comparative trial is to demonstrate that TKA performed using the Smith and Nephew Richards (SNR) Journey II TKA system is superior to standard TKA prostheses (Stryker Triathlon Total Knee System and Zimmer Persona® The Personalized Knee) in terms of knee biomechanics (knee kinematics and kinetics) and spatio-temporal gait parameters at 1-year post-TKA using the Computer-Assisted Rehabilitation ENvironment (CAREN). We will evaluate these parameters for level treadmill walking.

Secondary Objective: The secondary objective of this study will be to demonstrate that the Smith and Nephew Richards (SNR) Journey II TKA provides increased improvement from preoperative levels in pain and function in comparison to standard TKA prostheses. The new Knee Society Clinical Rating Scores (KSCRS) will be calculated preoperatively and at 1 year and 2 years postoperatively with the potential for longer-term follow-up. Patient questionnaires will be assessed preoperatively and at each postoperative interval.

Study Design: A prospective, randomized, post-market, comparative design will be employed.

Participants: A total of 60 participants will be enrolled in this study. Twenty (20) participants will receive the Journey II TKA System. Forty (40) participants will receive standard TKA: 20 will receive the Stryker Triathlon Total Knee System and 20 will receive Zimmer Persona® The Personalized Knee, which are commonly used in this zone.

Randomization: This study will utilize a computer-generated 1:1 randomization scheme. The randomization schedule will be maintained and controlled by Collaborative Orthopaedic REsearch (CORe) at the University of Alberta. The investigators and research associates will not have access to this schedule. When an eligible patient meets the criteria for inclusion in the study and signs the informed consent form, the research associate will open a sequentially-numbered envelope that contains the group allocation. Baseline gait evaluation will be completed for randomized patients. Any deviation from the assigned treatment group will be reported as a deviation from the protocol. Participants deviating from the randomization assignment will continue to be followed, and data collected will be reported as per intention to treat principles.

Estimated Study Duration: The enrollment period is estimated to last a maximum of 18 to 24 months. Participants will be evaluated per the evaluation schedule until the 2 year follow-up time point (secondary objective). It is possible that the study will be extended to longer-term follow-up to evaluate long-term performance.

Pre-operative visit

During the preoperative visit, patients who are possible candidates for this study will be screened to determine if they meet the inclusion/exclusion criteria. If the patient is a candidate, the investigator will propose participation in the study to the patient, and the patient will be given a consent-to-contact form by the investigator. If the patient consents to be contacted, the research associate would contact the patient to provide more details about the study. If the patient is willing to proceed with the study, an approved informed consent form must be signed by the patient prior to participating in any study related activities.

Once the patient has consented to participate in the study, preoperative data will be collected including: demographics, medical history, preoperative gait analysis and functional evaluation (KSCRS), EQ-5D - a standardized instrument that measures health-related quality of life, UCLA activity-level rating (UCLA), knee injury and osteoarthritis outcome score (KOOS), and the Forgotten Joint Score.

Follow-up visits

Gait analysis and patient-reported outcomes (PRO) data will be collected at the following postoperative intervals: 1-year (gait and PRO), 2 years (PRO) and potentially during longer-term follow-up (PRO).
