Brief summary

The purpose of this study is to determine whether a computer navigational unit can improve operating time and consistency during Knee arthroplasty when compared to knee arthroplasty without a computer navigational unit.

Detailed description

The ability to use a computerized navigational unit during knee arthroplasty can be a major benefit to surgeons that perform a small amount of knee arthroplasties. Navigational assistance can decrease surgery and anesthesia time as well as decreasing variation in posterior tibial slope and improved range of motion.
