Study Overview
Brief Summary
The purpose of this clinical trial is to understand the application value of the Orthopedic Joint Surgery Navigation System in assisting surgeons to accurately place prosthetic components in adult knee replacement surgery. It will also confirm its effectiveness and safety in clinical application.
Detailed Description
The purpose of this clinical trial is to understand the application value of the Orthopedic Joint Surgery Navigation System in assisting surgeons to accurately place prosthetic components in adult knee replacement surgery. It will also confirm its effectiveness and safety in clinical application. The main questions it aims to answer are:
Does the Orthopedic Joint Surgery Navigation System improve the accuracy of prosthetic component placement in knee replacement surgery? Is the Orthopedic Joint Surgery Navigation System superior to traditional total knee replacement What medical problems do participants encounter when taking medication ABC? Researchers will compare the Orthopedic Joint Surgery Navigation System with traditional total knee replacement surgery (using a "four-in-one" osteotomy guide) to see if the Orthopedic Joint Surgery Navigation System is superior to traditional total knee replacement in terms of prosthesis three-dimensional position, force alignment, patient satisfaction, functional scores, complications, etc.
Participants will:
End-stage knee osteoarthritis patients receive total knee replacement with the Orthopedic Joint Surgery Navigation System or traditional total knee replacement surgery Visit the clinic for examination and testing every 3 months Record their imaging data, satisfaction, functional scores, complications, etc.

Arms & Interventions
Robot-assisted total knee arthroplasty
Using an orthopedic joint surgery navigation system to assist total knee replacement
Intervention: Robot-assisted surgery (Procedure)
Conventional total knee arthroplasty
Using a conventional 4-in-1 osteotomy guide for total knee replacement
Intervention: Conventional total knee arthroplasty (Procedure)
Outcomes
Primary Outcomes
Postoperative patient satisfaction
Time Frame: Month 1, Month 3, Month 6, Month 12, Month 24
Use a questionnaire to investigate patients' satisfaction with their knee joint after surgery
Forgotten Joint Scores
Time Frame: Month 1, Month 3, Month 6, Month 12, Month 24
The Forgotten Joint Score (FJS) is a validated patient-reported outcome measure (PROM) tool designed to assess artificial prosthesis awareness during daily activities following total knee arthroplasty.The total score is 100 points. The higher the score, the better the degree of forgetfulness of the artificial joint.
WOMAC score
Time Frame: Month 1, Month 3, Month 6, Month 12, Month 24
Use WOMAC scoring scale to assess the condition of the knee joint. The WOMAC score consists of 24 items with a total score of 100. The higher the score, the more severe the limitation of joint function.
Knee Society Score
Time Frame: Month 1, Month 3, Month 6, Month 12, Month 24
The KSS score was assessed using the American Knee Society scoring criteria.The full score is 100 points. The higher the score, the better the patient's knee function.
Secondary Outcomes
- SF-12(Month 1, Month 3, Month 6, Month 12, Month 24)
- visual analogue scale score(Month 1, Month 3, Month 6, Month 12, Month 24)
- Range of motion(Month 1, Month 3, Month 6, Month 12, Month 24)
- Hip-knee-ankle angle(postoperative Day 1-3)
- Complication(Month 1, Month 3, Month 6, Month 12, Month 24)
