Titanium is also highly resistant to corrosion, which means it does not change after being placed in the body, notes BoneSmart. Unlike most other types of metal used in knee replacement surgery, pure titanium does not contain nickel, so it is a good choice for people who are allergic to nickel, according to the Hospital for Special Surgery. It is strong yet lightweight.

Difficulty in giving titanium a smooth, high-polish finish can affect the motion of the joint, notes the Hospital for Special Surgery. Cobalt chrome reaches that finish more easily. Cobalt-chromium alloys and titanium are two of the most popular materials used in knee replacements, notes BoneSmart.

The most significant benefit of knee replacement surgery is pain relief, notes WebMD. Since it removes the diseased tissues that cause pain, it can be successful at curing it. It can also improve joint function in some patients, but this is less reliable. Many patients still experience joint stiffness or weakness after having knee replacement surgery. Patients who follow rehabilitation guidelines are likely to have better outcomes, such as a wider range of motion.
