We had treated 3 athletes after surgical repair of Achilles tendon rupture according to a functional rehabilitation protocol. We measured the range of motion of ankle joint, pain intensity by visual analogue scale (VAS) score, the difference of calf circumference between normal and affected side, strength of dorsiflexor and plantarflexor of ankle before and after rehabilitation. The range of motion, VAS score, calf circumference, strength of dorsiflexor and plantarflexor of the affected ankle were improved after rehabilitation. There were no re-ruptures. All three patients returned to the sports activities after about 5 months. The comprehensive rehabilitation after surgical repair of Achilles tendon rupture was necessary for successful return to the sports activities. (J Korean Acad Rehab Med 2006; 30: 528-533)
