Medical implants have long been used in the body when joints or other body parts are no longer able to function properly on their own. This can be from damage to the body part from repetitive motion or natural wear and tear throughout the years. Replacement implants can be made from a variety of materials, including plastics, ceramics, or metal alloys. An alloy is a combination of two or more metals. The purpose of combining the metals is that they can be less expensive, and when combined, some metal alloys become much stronger than the individual metals used.
There are different scenarios for when implants should be used, and implants can be temporary or permanent. Permanent implants are generally used in surgeries for the hips or knees when the joints have given out due to age. Prior to using an implant, an orthopedic surgeon will first examine and determine how extensive the damage is and what needs to be replaced. Things such as weight, age, activity level, and overall health will be assessed and will help determine what type of implant to use.
How Implants Work
During the surgery, an implant is often secured to the existing bone by using an acrylic cement. When an implant is needed for a permanent solution, metal alloy implants are typically the best solution. Not only can an alloy last longer, but alloys have a durability that no plastic or ceramic can match.
Traditionally, titanium has been used for making implants and has been for years. The material is lightweight, corrosion resistant, non-toxic, and the human body won’t reject it. These qualities have all made titanium and titanium alloy practical for use in implants. However, there is another, more durable alloy that can be used: cobalt-chrome (CoCr). Cobalt-chrome is a very hard material that is stronger than titanium. The high strength makes it ultra-durable for orthopedic implants in bones and joints, primarily for femoral knee replacements because of the high forces that are put on the knee joint. Due to the strength of CoCr, it can last longer and provide more strength than titanium.
