Brief Summary

The purpose of this study is to conduct a prospective randomized controlled trial to compare the effects between two surgical procedures in the treatment of varus knee osteoarthritis.The hypothesis was that there would be no difference in mechanical axis correction between two surgical procedures.

Outcome Measures

Primary Outcomes (16)

  • The Visual Analog Scale score

    Assess pain on a scale of 0 (no pain) to 10 (worst possible pain).

    Baseline

  • The Visual Analog Scale score

    Assess pain on a scale of 0 (no pain) to 10 (worst possible pain).

    Postoperative 6 months

    Assess pain on a scale of 0 (no pain) to 10 (worst possible pain).

    Postoperative 12 months

  • The Visual Analog Scale score

    Assess pain on a scale of 0 (no pain) to 10 (worst possible pain).

    Postoperative 18 months

    Items include hip-knee-ankle (HKA), the medioproximal tibial angle(MPTA) and joint line Angle retraction(JLCA)

    Baseline

  • Radiological evaluation

    Items include hip-knee-ankle (HKA), the medioproximal tibial angle(MPTA) and joint line Angle retraction(JLCA)

    Items include hip-knee-ankle (HKA), the medioproximal tibial angle(MPTA) and joint line Angle retraction(JLCA)

    Postoperative 18 months

  • WOMAC

    This score evaluates the structure and function of the knee joint from three aspects of pain, stiffness and physical function, covering the basic symptoms and signs of the whole OA. The lower the score, the better the functional status of the patient.WOMAC score \< 21 is mild, 21 to 48 is moderate, \> 48 is classified as severe.

Model Details: Before initiating the trial, an investigator who was not involved in the study generated a computer-generated randomization list (block length 10, ratio 1:1). Allocation concealment was achieved by using opaque, sealed, sequentially numbered envelopes containing details of group assignment. Assignment occurred after baseline information was recorded. According to preoperative allocation, the patients were given open wedge high tibial osteotomy or closingwedge high tibial osteotomy.For the open wedge high tibial osteotomy group, Those who were randomly assigned to the OWHTO group, OWHTO Surgical procedure will be performed.For the closing wedge high tibial osteotomy group, hose who were randomly assigned to the CWHTO group, CWHTO Surgical procedure will be performed.
