Tightness after joint replacement surgery usually goes away in about two months, depending on the individual’s physical condition and recovery. Tightness in the affected area after joint replacement surgery is mainly due to scarring after surgery. Scar tissue is generally less elastic, so it will feel tight when stretching. After systematic rehabilitation, the tightness will be fully recovered within two months. After the joint replacement surgery, the scar will be slowly stretched and then plasticized and softened, and the sensation will slowly disappear. For some patients who have difficulty in exercising, they can go to a specialized rehabilitation department for rehabilitation treatment. If you have any discomfort after the joint replacement surgery, you should have a follow-up consultation in time, and do not blindly use medication to avoid aggravation of the condition.
