The ankle joint is made up of the tibia, fibula, and talus, and its stability comes from a combination of ligaments, tendons, and muscles. When the ankle is injured, through a fracture or sprain, this stability is compromised, which can limit motion, affect balance, and make weight-bearing difficult. Rehabilitation after injury focuses on restoring strength, mobility, and proper joint function while protecting the ankle from further damage.

Therapists often use braces, supports, or exercises to help the ankle regain strength and control. These tools allow patients to gradually return to daily activities while minimizing the risk of chronic instability. A solid understanding of the ankle’s mechanics and healing process is key for designing devices that provide the right level of support throughout recovery.
