Conditions

1.To compare the results of femoral component rotation between MA (Mechanical alignment) and rKA (Restricted kinematic alignment) surgery immediately after bilateral knee replacement surgery at Rajavithi Hospital. 2.To study the performance of the prosthetic knee (VAS, KOOS, FJS, ED 5Q 5L) by comparing MA (Mechanical alignment) and rKA (Restricted kinematic alignment) surgery in bilateral knee replacement surgery at Rajavithi Hospital at 3 and 6 months postoperatively and follow-up.
