After a complete recovery from knee replacement surgery, many people experience significant, even total, pain relief, as well as improvements in quality of life and psychological well-being. Many individuals can walk without a limp or a cane, even if they needed an assistive device before surgery.
Some people are able to enjoy more vigorous activities after surgery. However, implanting an artificial knee joint cannot restore knee function to the level people had when they were healthy. Excessive stress and weight placed upon an artificial knee joint can have a negative impact on the overall durability of the knee and cause swelling and pain. Therefore people who are contemplating knee replacement surgery should discuss their goals and expectations with their orthopedic surgeon.
