Describe the ligament attachments around the knee joints in the lower limb.
Understand the Problem
The question is asking for a description of the ligament attachments surrounding the knee joints in the lower limb. This involves identifying the major ligaments in the knee and their points of attachment to the bones involved in the knee joint.
Answer
Key knee ligaments are MCL, LCL, ACL, and PCL. They connect the femur to tibia and fibula, stabilizing the knee joint.
The main ligaments around the knee include the medial collateral ligament (MCL), lateral collateral ligament (LCL), anterior cruciate ligament (ACL), and posterior cruciate ligament (PCL). The MCL connects the femur to the tibia on the inner side, and the LCL connects the femur to the fibula on the outer side. The ACL and PCL cross each other inside the knee, stabilizing the knee joint during movement.

The main ligaments around the knee include the medial collateral ligament (MCL), lateral collateral ligament (LCL), anterior cruciate ligament (ACL), and posterior cruciate ligament (PCL). The MCL connects the femur to the tibia on the inner side, and the LCL connects the femur to the fibula on the outer side. The ACL and PCL cross each other inside the knee, stabilizing the knee joint during movement.
More Information
The knee is one of the most complex joints, supported by several ligaments that maintain its stability. These ligaments are crucial for activities like running, jumping, and squatting.
Tips
A common mistake is confusing the MCL and LCL with the ACL and PCL. Remember, the collateral ligaments are on the sides of the knee, while the cruciate ligaments are inside the knee.
