Question

If a lateral-to-medial load is applied to the foot, a counteracting moment is produced at the knee joint in a lateral-medial plane, which stretches the lateral collateral ligament and the cruciate ligaments. Estimate the moment produced by cruciate ligaments to that produced by the lateral collateral ligament. Use the force-deflection characteristics of the ligaments in your solution.

Explanation / Answer

Yes, the solution provided for this question is correct. As the moment equations are already given in the problem by taking the ratio we can get the solution. As the cruciate ligaments and lateral collateral ligament are having their own different stiffness so for calculating the force we need to find the deflection of the ligaments so that there will be less variables in the final answer and for finding the deflection the trignometric method can be used. So the final answer is correct.
