What is the primary function of the KAFO drop ring lock?

Explanation:
The main idea is that the KAFO drop ring lock is designed to hold the knee in full extension for stability during the stance phase of gait. The mechanism drops into place to block knee flexion, keeping the knee straight so the user can weight-bear safely and prevent buckling. When a unlock is needed for sitting or for the swing phase, the ring is released to allow knee flexion again. It doesn’t affect the ankle, so it doesn’t lock or position the ankle in dorsiflexion, and it doesn’t control knee rotation.
