NCT06033625

Brief Summary

Total knee replacement (TKR) is accepted as treatment of choice for end stage gonarthrosis. It is performed cemented or cementless and although cemented implants were shown to decrease bone density more than cementless fixations there is no evidence-based difference between them in the literature. As far as the investigators are concerned, the effect of cementation on patients' joint perception has never been studied so far.

Outcome Measures

Primary Outcomes (2)

  • Forgotten Joint Score-12 (FJS-12)

    a patient-reported outcome measure intended to determine a patient's ability to "forget" about their affected joint after surgery or treatment and uses a 5-point Likert response format (0, never; 1, almost; 2, seldom; 3,sometimes; and 4, mostly) with high scores indicate good outcome, which means a high degree of "forgetting" the joint

    1 year after index surgery and at the end of 5th year

  • Patient's Joint Perception questionnaire (PJP)

    The PJP is a single question with 5 possible answers, rating from the highest expected result "like a native or natural joint" to the worsening gradually as Artificial joint with no restriction, Artificial joint with minimal restriction, Artificial joint with major restriction and "a non-functional joint"

    1 year after index surgery and at the end of 5th year

Secondary Outcomes (1)

  • Western Ontario and McMaster Universities Arthritis Index (WOMAC)

    1 year after index surgery and at the end of 5th year
