Outcome Measures

Primary Outcomes (9)

  • Patient reported outcome measures

    The following patient reported outcome measures will be evaluated: Knee Injury and Osteoarthritis outcome score. The score is a percentage score from 0 to 100, 0 representing extreme problems and 100 representing no problems.

    Preoperative

  • Patient reported outcome measures

    The following patient reported outcome measures will be evaluated: Knee Society Score. The score is a percentage score from 0 to 100, 0 representing extreme problems and 100 representing no problems.

    Preoperative

  • Patient reported outcome measures

    The following patient reported outcome measures will be evaluated: EuroQoL. The score is a percentage score from 0 to 100, 0 representing extreme problems and 100 representing no problems.

    Preoperative

  • Patient reported outcome measures

    The following patient reported outcome measures will be evaluated: Pain Catastrophizing Scale. The score is a percentage score from 0 to 52, 0 representing no problems and 52 representing extreme problems.

    Preoperative

  • Change in patient reported outcome measures

    The change for the following patient reported outcome measures will be evaluated (compared to preoperatively): Forgotten Joint Score. The score is a percentage score from 0 to 100, 0 representing extreme problems and 100 representing no problems.

    Postoperatively at 6 weeks, 6 months, 1 year and 2 years.

  • Change in patient reported outcome measures
