The normal capsular pattern described as plantar flexion greater than dorsiflexion is observed in which joint?

• A. Subtalar joint
• B. Midtarsal joint
• C. Talocrural joint
• D. Hip joint

Answer: (C)

The main idea is how a joint’s capsular pattern reveals which joint is affected. For the ankle, specifically the talocrural joint, the normal capsular pattern has plantarflexion limited more than dorsiflexion. This means when stiffness or inflammation binds the joint capsule, you’ll notice a greater loss of the ability to point the toes downward than to pull the foot up toward the shin. The talocrural joint is the primary hinge between the tibia, fibula, and talus that enables these motions, so this pattern points to that joint. Other joints mentioned have different patterns, so their ROM loss wouldn’t follow the same plantarflexion-to-dorsiflexion priority.
