Abstract
Computer-aided surgery (CAS) aims not to replace the surgeon but to assist him in difficult areas. The cost of the system means it has to produce markedly improved clinical results. CAS gained acceptance in neurosurgery.
In knee surgery, CAS has improved the accuracy of tibiofemoral alignment and bone cuts. It has also helped deal with problems such as soft tissue balancing.
This report of our experiences looks at intra-articular and extra-articular forces around the knee, the use of spacer blocks, surgical techniques and results.
