Tendon separation surgery is tendon adhesion release surgery, how long it takes to recover after the surgery depends on the degree of adhesion and the number and amplitude of rehabilitation exercises, generally 1~3 months. After the tendon separation surgery, there is no need to fixate the tendon with plaster or brace. Generally, you can start to exercise the finger or wrist flexion and extension after 1~2 days, and then you can gradually increase the number of activities, but the speed should not be too fast, so as not to avoid the local hemorrhage and swelling, or hemorrhage. Generally speaking, 4 to 6 weeks of rehabilitation is needed after adhesion release surgery, and 1 to 3 months of recovery after suture removal with physical rehabilitation therapy. Uninterrupted postoperative exercise and effective rehabilitation measures are conducive to the recovery of hand function, and it is recommended that they be performed under the guidance of a doctor, not without authorization.
