Knee Practice Test 2026 – Complete Exam Preparation

The term for the infolds of synovial membrane in the knee is "plica." Plicae are folds or pleats of the synovial membrane that can be found within the joint cavity. They are a normal anatomical variation and play a role in the functioning of the knee joint. Their presence can help to increase the surface area of the synovial membrane, which is beneficial for producing synovial fluid and facilitating joint nutrition and lubrication.

In contrast, the meniscus refers to the crescent-shaped cartilage structures that provide cushioning and stability to the knee, as well as aiding in weight distribution. The capsule refers to the fibrous structure that encases the knee joint, while articular cartilage is the smooth tissue covering the ends of bones within the joint, enabling smooth movement and reducing friction. Each of these structures serves important but distinct functions in the knee, underscoring the unique role that plicae play in relation to the synovial membrane.
