About this trial

This is an interventional treatment trial for Osteoarthritis, Knee

Eligibility Criteria

50 Years - 70 Years (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • patients undergoing total knee replacement surgery for primary osteoarthritis
  • no previous open major surgery in the joint ( e.g. osteotomy)
  • unilateral operative treatment, with no plans for surgical treatment of the contralateral knee in the near future
  • patients living in the local hospital district (Pirkanmaa Hospital District)

5. Study Description

Brief Summary
The present randomized controlled trial is designed to compare one novel total knee replacement (TKR) design and two conventional TKR designs in terms of functional outcome. 80 patients will be randomized in each of the three arms (240 altogether).
Detailed Description
The study will compare the short-term functional outcome (at 2 years) of TKR performed with a novel TKR design (Persona , Zimmer, Warsaw, IN, USA) against TKRs performed with two conventional designs (PFC, DePuy, Warsaw, IN, USA and Nexgen, Zimmer, Warsaw, IN, USA).

Interventional Study Model
Parallel Assignment
Model Description
Patients will be recruited from Coxa outpatient clinic according to inclusion and exclusion criteria. The participating orthopedic surgeons will recruit patients along their out-patient work. The indications for the surgical treatment in the study will follow the routine clinical guidelines of the hospital. When TKR surgery is decided, the eligible patients will be informed and those willing to participate will be randomized into one of the three implant groups.
Masking
ParticipantCare ProviderOutcomes Assessor
Masking Description
Patients will be operated upon using the implant allocated in randomization. Participants are blinded to the implant design used for their operation. Staff at the ward is also blinded. And the physiotherapists conducting the follow-up visits (at 2-3 months, 1 year and 2 years, i.e. the outcome assessors) are also blinded to the allocation.
