Outcome Measures

Primary Outcomes (1)

  • Changes in patients reported outcome measures - Oxford Knee Score (OKS)

    To explore differences between outcome in patients treated with use of with Nexgen and Persona prosthesis. Results range from 0 to 48, with higher scores corresponding to better outcomes.

    baseline (preoperatively) and 6-months postoperatively

Secondary Outcomes (18)

  • Changes in patients reported outcome measures - Oxford Knee Score (OKS)

    1 week and 6-8 weeks post-operatively

  • Changes in patients reported outcomes - Oxford Knee Score Activity & Participation Questionnaire (OKS_APQ)

    1 week, 6-8 weeks and 6 months post- operatively

  • Changes in patients reported outcomes - EuroQol (EQ- 5D-5L)

    1 week, 6-8 weeks and 6 months post- operatively

  • Changes in patients reported outcomes - Forgotten Joint Score (FJS)

    6-8 weeks and 6 months post-operatively

  • Changes in patients reported outcomes - UCLA (University of California) score

    6-8 weeks and 6 months post-operatively

  • +13 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Listed for a primary total knee replacement (TKR) at the Orthopaedic and Rehabilitation Department Medical University of Warsaw
  • Indication for the TKR is primary osteoarthritis of the knee joint involving one or more compartments
  • Aged 18 or over
  • Patient willing to provide full informed consent to the trial

You may not qualify if:

  • Listed for a single-stage bilateral TKR procedure
  • Severe symptoms in the contralateral knee so as to require staged bilateral knee replacements within 6 months of the primary procedure
  • Fixed flexion deformity of 15 degrees or greater who will require excessive resection of the distal femur
  • Clinically assessed uncorrectable varus/valgus deformity of 15 degrees or greater
  • Any co-morbidity which, in the opinion of the investigator, is severe enough to present an unacceptable risk to the patient's safety
  • Inflammatory arthritis
  • Previous septic arthritis in the affected knee joint
  • Previous surgery to the collateral ligaments of the affected knee
  • A contralateral total knee replacement that has been implanted less than one year from the date of consultation
  • A contralateral total knee replacement that is severely painful
  • Patients on warfarin or novel oral anticoagulants (NOACs)
  • Will not be resident in the catchment area for at least 6 months post-surgery
  • Undertaking the surgery as a private patient
  • Patients who, in the opinion of the clinical staff, do not have capacity to consent
  • Patients who are pregnant
  • +1 more criteria
