Study Arms (2)

NexGen

ACTIVE COMPARATOR

Patients undergoing total knee replacement for treatment of primary knee ostearthritis with use of Zimmer Biomet NexGen prosthesis

Procedure: Total knee replacementDiagnostic Test: BiomechanicsDevice: NexGen Ps or Bioimplanti K-MOD implant

K-Mod

ACTIVE COMPARATOR

Patients undergoing total knee replacement for treatment of primary knee ostearthritis with use of Bioimplanti K-MOD prosthesis

Procedure: Total knee replacementDiagnostic Test: BiomechanicsDevice: NexGen Ps or Bioimplanti K-MOD implant

Interventions

Participant will undergo total knee replacement performed via anterior parapatellar approach with either Posterior-stabilized or retaining cruciate-retaining with dynamic congruence implant

K-ModNexGen
BiomechanicsDIAGNOSTIC_TEST

Participants will be asked to perform biomechanical assesment before and following surgery at baseline, 6-8 weeks and 6-months postoperatively

K-ModNexGen

Participant are randomly allocated to receive one of the NexGen PS or Biomplanti K-MOD total knee implant for treatment of end-stage knee osteoarthritis.

K-ModNexGen
