Tendon adhesion is easy to occur after flexor tendon rupture, and tendon release can be carried out 3 months after operation. Exercise actively under the guidance of a doctor 24 hours after operation and cooperate with rehabilitation treatment. Obvious scars can be treated by plastic surgery, and the effect is generally good about 1 year after operation, but if the function is affected, the operation can be carried out 3-6 months in advance.
