One procedure that a knee specialist may use to treat a bad knee, is to talk to their patient about having their knee replaced. After so much therapy and medication, sometimes the knee just does not recover, and a replacement option is recommended. However, replacing the knee is more than just simply swapping out one knee for another, but also involves a special bone cement. Just like the kind of cement used in construction, this special bone cement will help hold the new knee in place, but there is another option that can accomplish the same goal, but does not rely on bone cement.

Knee Replacements Using Cement and the Non-Cement Option
As of right now, then it comes to knee replacement, more often than not, the bone cement is used, and a knee specialist will tell their patients that the cement has a solid reputation and can last for at least two to three decades. However, there are many factors that have to be in place in order for the cement to work, and some of the factors include things like weight, activity level, and whether or not the cement sets the way it is supposed to. Here is more information on both the cement and non-cement option for knee replacement:
- Cemented fixation: In a normal knee, there are four main ligaments that surround and protect the knee, but during a knee replacement, all of those are too damaged to hold the knee properly, which is where the bone cement comes in. The cement will cure in place, but there can still be circumstances for it to not hold correctly such as the way the knee moves, and the stresses that are placed on the knee. If the stresses are too much, then the cement will not hold the knee in place, and the replacement will start to become loose, which will lead to other problems such as the bone being affected.
- Non-cemented fixation: The newer knee implants now have a way for the implant to be held in place without cement, but the implant will attach to the bone. The implant will be covered with the natural bone in the body, but it does require a much longer healing time. However, despite the longer time it takes to heal, the success rate is pretty much the same as it is for the cemented option, and right now comparison studies are being conducted to see which the better choice is, but both have helped people with chronic knee problems.
Cement is used in construction work to help hold things in place, but who knew that a substance just like it can also be used in the medical field. When a knee specialist talks to a patient about knee replacement, they will mention a special bone cement that can be used to help a replaced knee recover. The cement will hold the replacement knee in place while it heals, but there is also a non-cement option that will allow the natural bone in the body to grow over it over a certain amount of time. Though no matter with option is used, the cement or non-cement option, a person will get a new knee that will allow them to move around like they once were able to.
