After knee meniscus repair, knee joint cleaning surgery, etc., you can bend the knee for foot soaking; if the knee anterior cruciate ligament reconstruction surgery is not recommended to bend the knee for foot soaking at an early stage. 1. Knee meniscus repair surgery: such as knee meniscoplasty, partial meniscectomy or knee meniscus suture surgery, you can bend your knees to soak your feet during the postoperative recovery period. The main point is that postoperative foot soaking with the knee bent generally does not affect the recovery of the postoperative meniscus. 2. Knee joint cleaning surgery: such as knee joint free body, cartilage damage, synovial hyperplasia of the knee joint, etc., in the knee joint lesion tissue cleaning surgery, you can also be soaking feet. Foot soaking after knee joint cleaning surgery for this kind of disease generally does not affect the prognosis. 3. Knee arthroscopic anterior cruciate ligament reconstruction: this kind of minimally invasive knee surgery needs to maintain the joint state of 0~20° for a certain period of time after the surgery, therefore, it is not possible to bend the knee to soak the feet and other activities in the early period after the surgery. Whether or not you can soak your feet after minimally invasive knee surgery is mainly based on the disease and the surgeon’s recommendation.
