Comparison Between Velys J&J Robotic-assisted and Cori S&N Robotic-assisted Total Knee Arthroplasty

This randomised controlled trial will include patients with end-stage osteoarthritis of the knee undergoing primary TKR. Patients meeting the criteria that consent to be in the study will be randomised at a ratio of 1:1 to either Velys J\&J robotic-assisted or Cori S\&N robotic-assisted TKR. The primary objective will assess pre- and postoperative HKA angle, CPAK and range of motion using goniometer to compare two groups.The secondary objectives are to compare patient expectation, functional ability, quality of life using functional 48-point Oxford Knee Score and Forgotten joint score.
