Reconstructing a Cow's Knee Lab
Objective: To learn the function of the knee and how its ligaments work to create the movement the knee makes by taking apart the knee and reconstructing it with different materials to replace the ligaments.
Hypothesis: If we replace the cow’s knee tendons with rubber bands then it will work like a new knee because the rubber bands will provide the support, strength, and flexibility it needs.
Safety: Wear gloves while handling the knee, use precaution when using the Drill, and clean the utensils you use and the table you use before and after this lab.
Independent: Cow’s Knee
Dependent: The Quality of the Function of the Cow’s Knee
Control: Fully Fictional Cow Knee
Bit – Philips
1: Gather Supplies
2: Mark areas on the knee with the marker, where the ligament attachment points are for the PCL 3: Drill holes with the Drill bit attachment in the areas that you have marked for the PCL 4: Screw in the screws with the Philips bit attachment into the holes you have drilled 5: Wrap a rubber band around the two screws that will substitute for the PCL 6: Repeat steps 2-5 with the LCL, MCL, and Patellar Ligament
Conclusion: The knee that our lab created was successful in the take of making the movement of the knee, but the quality was not as great as a normal knee. It didn't move as smoothly and had a hard time keeping the knee in place, but as said before it still created the movement of the knee.
