Abstract:
Acute Achilles tendon rupture (AATR) is one of the most common sport injuries in clinical practice, which is usually treated surgically or non-surgically. Regardless of treatment choice, early weight bearing should be encouraged to promote tendon healing. After ruptured Achilles tendon is healed, permanent defects in the biomechanical function of the patients′ affected lower limbs are found and performance in running, jumping, and competitive sports is affected, which may be due to a decrease in the flexion strength of the ankle as a result of tendon elongation following the repair of an Achilles tendon. The methods for evaluating tendon elongation can be divided into indirect measurement and direct measurement. Achilles tendon resting angle (ATRA) is the most commonly used and reliable indirect measurement index, while ultrasound and MRI are commonly used for direct measurement. However, there is no recommended "gold standard" at present. Among the potential influencing factors of tendon elongation, the choice of surgical or non-surgical treatment, different tendon suturing methods and start time of weight bearing have attracted attention and are still controversial. The authors reviewed the research progress of tendon elongation's effects on lower limb biomechanics, evaluation of tendon elongation, and factors affecting tendon elongation so as to provide reference for clinical diagnosis and treatment as well as related researches.
