After the drainage tube is removed (about two or three days), the patient is encouraged to get out of bed, practice walking with a walker or crutches, and start bedside rehab exercises, and can be discharged from the hospital about seven days after surgery. The total artificial knee can be shortened to about five days. If the joint is fixed by porous fixation or hydroxyapatite spraying, a walker or crutches are usually used for six weeks to three months after surgery to reduce the weight bearing on the joint so that the bone can grow into the porous surface of the artificial joint and create a strong bond. With bone cement fixation of the artificial joint, the limb can be weight-bearing immediately after surgery, shortening the duration of crutch use and often eliminating crutches in about two weeks. In general, daily activities return to normal three months after surgery. Occasionally, patients may still feel slight swelling or numbness in the limb, but as long as there is no increase in pain or inflammation, there is no need to pay much attention to it, as it will gradually get better with time.
