Which structure is a ligament located inside the joint capsule?

• A. Extracapsular ligament
• B. Capsular ligament
• C. Periarticular ligament
• D. Intracapsular ligament

Answer: (D)

Inside a joint, ligaments can lie inside or outside the capsule. When a ligament crosses within the joint capsule and the synovial cavity, it’s called an intracapsular ligament. These ligaments help stabilize the bones from within the joint itself, and a classic example is the ACL or PCL in the knee. The other terms describe ligaments outside or around the capsule: extracapsular ligaments lie outside the capsule, periarticular ligaments are around the joint, and capsular ligaments are thickened parts of the capsule itself rather than separate structures crossing the joint. So the ligament located inside the joint capsule is intracapsular.
