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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| WOMAC score | 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. |
| Postoperative patient satisfaction | 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 | 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. |
| Knee Society Score | 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
| Measure | Time frame | Description |
|---|---|---|
| Complication | Month 1, Month 3, Month 6, Month 12, Month 24 | Record the patient's postoperative complications. For example, Persistent pain, fracture, superficial local infection, infection, thromboembolism. |
| Range of motion | Month 1, Month 3, Month 6, Month 12, Month 24 | Physical examination to assess the knee's range of motion |
| SF-12 | Month 1, Month 3, Month 6, Month 12, Month 24 | The health status of patients was assessed using the SF-12 health-related quality of life scale. The higher the score, the better the quality of life. |
| visual analogue scale score | Month 1, Month 3, Month 6, Month 12, Month 24 | Visual analogue scale (VAS) for pain assessment。0 means no pain, 10 means the most painful, the higher the value, the higher the pain level of the patient |
| Hip-knee-ankle angle | postoperative Day 1-3 | Measuring Hip-knee-ankle angle in radiology |
Other
| Measure | Time frame | Description |
|---|---|---|
| mLDFA | preoperative Day 1-3, postoperative Day 1-3 | the lateral angle between the mechanical axis of the femur and the tangent of the distal end of the femoral prosthesis. The target value is 90°. \>90° is varus, and \<90° is valgus. Varus or valgus exceeding 3° is defined as femoral prosthesis position deviation. |
| Tibial posterior tilt angle (β angle): | preoperative Day 1-3, postoperative Day 1-3 | on the standard lateral knee X-ray, the angle between the anatomical axis of the tibia and the lower surface of the tibial prosthesis. |
| Femoral prosthesis flexion angle (α angle) | preoperative Day 1-3, postoperative Day 1-3 | on the standard lateral knee X-ray, the angle between the anatomical axis of the distal femur and the vertical line of the distal femoral prosthesis |
| mMPTA | preoperative Day 1-3, postoperative Day 1-3 | medial angle between the mechanical axis of the tibia and the tangent of the tibial prosthesis, the target value is 90°, \<90° is varus, \>90° is valgus, and valgus exceeding 3° is defined as tibial prosthesis position deviation |
