Question

multiple choice question

the joint capsule of the knee encloses which aspects of the knee joint?

lateral and posterior
anterior, lateral, and posterior
anterior and posterior

Explanation:

Analyze knee joint capsule anatomy

The knee joint is a complex synovial joint. Its articular capsule (joint capsule) is unique because it is incomplete. It does not form a continuous, uniform sleeve around the entire joint. Specifically, the capsule is absent on the anterior aspect of the knee. Instead, the anterior region is covered and protected by the patella and the patellar ligament/quadriceps tendon.

Determine enclosed aspects

Because the anterior aspect lacks a true fibrous capsule, the joint capsule only encloses the lateral, medial, and posterior aspects of the knee joint. Looking at the provided options:

• "Lateral and posterior" correctly identifies the regions where the capsule is present.
• "Anterior, lateral, and posterior" is incorrect because the anterior aspect is not enclosed by the capsule.
• "Anterior and posterior" is incorrect for the same reason.

Therefore, the joint capsule of the knee encloses only the lateral and posterior aspects of the joint.

Answer:

• (A) Lateral and posterior (Correct answer)
• (B) Anterior, lateral, and posterior
• (C) Anterior and posterior
