You need to be careful about putting high stress and pressure on the knee joints. You should be very careful while walking and making odd movements after your knee joint surgery. To avoid putting stress on the knees you can use things such as long-handled showers, sponges, raised toilet seats, chairs or benches at the time of the shower, use sticks while dressing yourself and to grab items from the upper racks, don’t use too much stair climbing, etc.
