Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Vanguard with KneeAlign 2

Having total knee arthroplasty surgery with the use of a navigation system KneeAlign 2.

Group Type ACTIVE_COMPARATOR

KneeAlign 2

Intervention Type DEVICE

Patients suffering non-severe varus deformity Osteoarthritis will be enrolled and randomly assigned into one of two treatment groups. Patients in investigational group will be treated with total knee arthroplasty and the accelerometer-based navigational device. Patients in control group will be treated with total knee arthroplasty with conventional instrumentation.

Vanguard without KneeAlign 2

Having total knee arthroplasty surgery with the use of conventional surgical instruments, and without a navigation system KneeAlign 2.

Group Type NO_INTERVENTION

No interventions assigned to this group
