Materials needed

For this activity you’ll need:

1. The worksheet for this activity (either opened in a PDF viewer on a desktop/tablet computer or printed out).

2. One of the following versions of the knee kit:
   • Minimal muscle set knee kit
   • Full muscle set knee kit

   Be sure that your knee kit has the Iliotibial (IT) tract/band attached; this is one of the ligaments you will knock out. You do not need any of the muscles for this activity. If your knee kit has muscles attached, remove all the muscles. You can leave the patella to hang from the patellar ligament or you can remove the patella by unscrewing the screw behind the patellar ligament using the Allen wrench. If your knee kit doesn't look like one of the kits in the image above, follow these instructions for assembling or disassembling your kit.
   

While this activity can be done with the Mini version of the Knee Kit, be aware that the IT tract is a significant stabilizer of the knee. Since the Mini version of the Knee Kit does not include an IT tract, your results will not include its contributions. If you're doing this activity without an IT tract, it's best to assume that any conclusions you draw are for a knee in which the IT tract is already damaged or without taking into account its contributions.

3. The Allen wrench and ruler from your kit (if your kit has two Allen wrenches, you'll need the larger one).
