One of the Most Common Knee Injuries Is the Tearing

question 30

Multiple Choice

One of the most common knee injuries is the tearing of the anterior cruciate ligament (ACL) . How would an injury like this affect the function of the knee?

• A)Ligaments attach muscle to bone, so tearing of the ligament would mean that the knee muscles would no longer be able to cause the joint to bend.
• B)Ligaments lubricate the cartilage in a joint, and tearing the ligament would let the lubricant leak out. This would cause bones in the knee to grind against each other, making it painful to bend the knee.
• C)Ligaments hold the bones of the knee in the proper orientation. Tearing the ligament could disrupt the alignment of the knee, making the knee difficult to bend.
• D)Ligaments are the muscles that surround a joint. Muscle tears can be painful, but they heal quickly and they usually do not affect knee function.
