The ten minute video shows the essential steps of a cemented total knee replacement. The key to long term success of knee arthroplasty is a combination of proper soft tissue balances, along with precise bone cuts. The following should be the aims.
1, Adequate soft tissue releases are done to ensure that you have a  neutral to valgus knee with no flexion deformity before beginning the first bone cut.
2, The distal femoral cut should be in five to six degrees Valgus, in relation to the long axis of the joint.
3, The upper tibial cut should be neutral or up to two degrees Varus, with a three degree posterior slope.
4, The cut surface of distal femur should exactly match the inner surface of the implant.
5, The flexion, extension and mid flexion gaps should be equal.
6, Proper cementation.
7, Precise patellar tracking after implantation, with or without patellar replacement.
