| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Standard knee cutting guides | Active Comparator | Standard cutting guides use traditional instrumentation to determine knee implant positions. During surgery, a rod is placed in the leg bone and the cutting guide is attached to that rod. |
|
| Patient specific cutting guides | Active Comparator | Patient specific cutting guides are custom-made for each patient based on Magnetic Resonance Imaging (MRI). Before surgery, MRI of the knee is done and used to create a cutting guide that is formed to the exact shape of the knee. The patient specific cutting guides have platforms that can be attached to the bone, so the rod does not need to be placed in the leg bone. |
