Are You A Candidate For Knee Replacement Surgery?Do you find it hard to perform simple tasks around the house, such as walking up stairs or picking up laundry? Do you suffer from knee pain even when you’re just sitting or lying down? Do you feel stiff and/or have limited mobility? Is your knee deformed? If you answered yes to any of these questions, you may be dealing with the effects of arthritis in the knee – the largest joint in your body – or other conditions that are causing havoc in that area, making you a candidate for surgery.
