A small tear of the Achilles tendon can heal on its own, while a large tear cannot heal on its own. If a small part of the Achilles tendon is torn, and the extent of the tear is less than 1/3 of the tendon, it can grow back on its own through conservative treatment, immobilization in a cast or a brace, and oral medication such as Bone Marrow Capsules. If the tear is more serious and the Achilles tendon retracts, the Achilles tendon will not be able to grow back on its own because of the poor blood flow in the area, and surgery is needed to repair the Achilles tendon or reconstruct the Achilles tendon. After the surgery, you need to rest in bed and do functional exercises in bed to avoid rupturing the Achilles tendon too soon, and you can recover slowly in about 3 months. Therefore, in case of Achilles tendon rupture, you need to go to the orthopedic department of the hospital in time to clarify the degree of injury, and take conservative treatment or surgical treatment.
