After a patient has a tendon injury, after correct treatment, there is no clear and uniform clinical time, because different parts of the tendon injury, the healing time is not the same, for example, the patient has a partial injury of the Achilles tendon of the heel, and took conservative treatment, giving the external application of creams to invigorate blood circulation and eliminate blood stasis, and at the same time, external fixation fixed, generally in the treatment of 6 weeks or so can be recovered. If the same patient has a complete rupture of the Achilles tendon in the foot, surgical treatment, under epidural anesthesia for incision and exploration, Achilles tendon anastomosis, usually need 7-8 weeks after surgery to gradually heal. If the patient has a closed partial injury to the flexor tendon in the finger area and is immobilized with a finger plate, gradual healing usually takes 4-5 weeks after treatment. Therefore, the healing time is different for patients with different tendon injuries.
