Study Arms (2)
NexGen
ACTIVE COMPARATORPatients undergoing total knee replacement for treatment of primary knee ostearthritis with use of Zimmer Biomet NexGen prosthesis
K-Mod
ACTIVE COMPARATORPatients undergoing total knee replacement for treatment of primary knee ostearthritis with use of Bioimplanti K-MOD prosthesis
Interventions
Participant will undergo total knee replacement performed via anterior parapatellar approach with either Posterior-stabilized or retaining cruciate-retaining with dynamic congruence implant
Participants will be asked to perform biomechanical assesment before and following surgery at baseline, 6-8 weeks and 6-months postoperatively
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.
