The Achilles tendon is the largest and strongest tendon in the human body, capable of withstanding forces twelve times a human's body weight. It is essential for locomotion enabling efficient walking, running, and jumping. Acute tendon rupture is a debilitating injury that often requires prolonged rehabilitation. It triggers a complex healing cascade progressing through overlapping inflammatory, proliferative, and remodeling phases over months. However, tissue often forms fibrotic scars, leaving the tendon susceptible to adhesions and re-rupture. Even after surgical repair, the tendon may heal in an elongated, less stiff state. Additionally, the calf muscles frequently undergo atrophy and fatty degeneration. These structural changes in the muscle tendon unit lead to persistent plantarflexion weakness and reduced push off strength, making full functional restoration a significant challenge. This research paper examines evidence based rehabilitation strategies to enhance tendon healing and functional recovery. Early controlled mechanical loading and mobilization have been shown to promote tendon maturation and reduce re-rupture risk. Muscle preservation therapies can help with disuse atrophy. Adjunctive biological treatments, such as platelet rich plasma injections, have been explored to accelerate the healing process, though clinical outcomes remain inconclusive. By integrating insight from the biology of tendon repair and muscle protection, this research paper aims to inform more effective post rupture rehabilitation protocols that safely minimize re-injury risk and optimize functional recovery.
