Our legs carry all our body weight every time we perform any physical activity, especially while we are standing. The skeletal system of our legs is divided as the following;
- Femur, also called the thigh bone.
- Tibia, which is the leg bone.
- Patella, which joins femur and tibia with a hinged joint.
It is very important to take great care for the knee, as it provides flexibility for the legs, which allows us to carry out various activities. An injury to the knee causes severe pain and inability to use the legs for any day-to-day work. These injuries can be caused by direct blows to the kneecap and can also be damaged internally if stretched or twisted more than the hinge joint is capable to tolerate. When the injuries go to the point of doing physical damage to the adjacent bones, the need arises to go for knee replacement surgery.
Today, various sorts of joint replacement surgeries have become very common, as surgery provides a permanent solution to the problem and knee replacement surgery is no expectation today.
If there is a chance that the bones will grow, plastic or metal replacements are used instead of the joint, which is also called prosthesis. There are diverse conditions in which knee replacement surgery is opted for.
- Unrestricted implant takes place when prosthesis is not connected to anything. It is based on the ligaments and muscles around the knee to establish itself.
- Semi-limited implant is considered when the surgeon removes the ligaments of inner knee if he feels that this would provide more stability.
- Constraint implant is generally not the first choice. This implant contains the entire mechanism of knee joint made and replaced artificially and is performed if the knee is badly damaged.
Once you have had knee replacement surgery, there are a lot of precautions and exercises involved to keep the knee functioning properly, because the body has to adapt to the new artificial things inserted inside.
There may also be complications such as infection, blood clotting, loosening or stiffness of the joint while the body is adapting after surgery. This can cause some discomfort, followed by pain, but it indicates that the body is getting accustomed to the implants and the discomfort soon disappears. Within some span of time, the body will start to function as naturally as it can, but precautions must be taken no matter how comfortable the patient feels.
To conclude and answering to the question posed in the title, we can confidently say that knee replacement surgery is 100% safe option if you have to opt for it.
