Outcome Measures

Primary Outcomes (4)

  • Postoperative patient satisfaction

    Use a questionnaire to investigate patients' satisfaction with their knee joint after surgery

    Month 1, Month 3, Month 6, Month 12, Month 24

  • Forgotten Joint Scores

    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.

    Month 1, Month 3, Month 6, Month 12, Month 24

  • WOMAC score

    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.

    Month 1, Month 3, Month 6, Month 12, Month 24

  • Knee Society Score

    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.

    Month 1, Month 3, Month 6, Month 12, Month 24

Secondary Outcomes (5)

  • 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

Other Outcomes (4)

  • mLDFA

    preoperative Day 1-3, postoperative Day 1-3

  • mMPTA

    preoperative Day 1-3, postoperative Day 1-3

  • Femoral prosthesis flexion angle (α angle)

    preoperative Day 1-3, postoperative Day 1-3

  • +1 more other outcomes

Study Arms (2)

EXPERIMENTAL

Using an orthopedic joint surgery navigation system to assist total knee replacement

Procedure: Robot-assisted surgery

ACTIVE COMPARATOR

Using a conventional 4-in-1 osteotomy guide for total knee replacement

Procedure: Conventional total knee arthroplasty

Interventions

Orthopedic surgeons perform total knee arthroplasty using an orthopedic joint surgery navigation system

Robot-assisted total knee arthroplasty

Orthopedic surgeons perform total knee arthroplasty using a 4 in 1 osteotomy guide
