Explanation:

Identify the biomechanical process

Using the Screw-Home Mechanism knowledge point
The question asks what structures become twisted and taut when locking the knee. Locking the knee (full extension) involves a crucial biomechanical rotation of the femur on the tibia.

Analyze structural changes during extension

Using the Knee Joint Anatomy knowledge point
During the final degrees of knee extension, the femur rotates medially on the tibia (or the tibia rotates laterally on the femur if non-weight-bearing) to "lock" the joint. This rotation twists the cruciate ligaments (specifically the anterior and posterior cruciate ligaments) and pulls them taut, stabilizing the joint in full extension.

Evaluate the visible options

The visible options are "Menisci" and "Tendons". The correct anatomical answer to this standard question is the ligaments (specifically the cruciate ligaments). Since the options are cut off, we identify "Ligaments" as the correct choice that would complete this multiple-choice question.

Answer:

• Menisci
• Tendons
• Ligaments (Correct answer)
