What is Knee Replacement Surgery?
Knee replacements are also known as knee arthroplasty. They are surgeries that are usually performed when the person suffers from a particular medical condition called arthritis, or it can also be due to reasons like cartilage defects, ligament tear and major fractures in the area that call for the replacement. It is a procedure to improve or partially and fully remove the surfaces of the knee that reduces the pain, removes inability, and creates durability for the knee in movement and flexibility.
Why Would One Need Knee Surgery?
Other reasons for Knee Surgery?
- Rheumatoid arthritis: The lining of the knee is attacked and destroyed by the body’s immune system.
- Deformities: People with bent legs or “knock-knees” often undergo surgery to restore the position of the knee.
- Knee injuries: When a bone is broken or if there is a tear in the ligament around the knee, resulting in arthritis causing great pain and gradually limits your movements.
Types of Knee Replacement Surgery
- Total Knee Replacement
- Partial Knee Replacement
- Patellofemoral Replacement
- Complex Knee Replacement
- Cartilage Restoration
1. Total Knee Replacement
This is the most common traditional method used by doctors to treat a damaged knee, the surgeon replaces the surfaces of the thigh bone and shin bone that connects to the knee. The total knee replacement after the surgery functions as a natural knee and can be customized enough even to work and fit the body type of every kind in the way you want it respectively. The surgeon performs four-step techniques in this replacement.
- Firstly, the bone and the cartilage are treated and removed,
- The second step is to fit and fix the implants on the area or the bone either attaching it or making it happen certainly.
- The third step is fixing a plastic button below the kneecap,
- Finally, the surgeon inserts and fixes a plastic spacer between the knee and the femur (thigh bone) to accomplish smooth flexibility and functioning of the knee.
Finally, there should be a proper alignment, after which the bone must be carefully fitted for a fair movement.
2. Partial Knee Replacement
The partial knee surgery is applicable and suitable for individuals who have strong knee ligaments to resist the surgery as only the infected and the least part is replaced by protecting most of the natural bone, ligaments, and tissues in place for the rest of the bodily movements and if only one side of your knee, is affected with arthritis this surgery can be performed.
Partial knee replacement can be done through a smaller slit that is required for performing the total knee replacement. The surgeon removes the stiffness in joints called the arthritic and then replaces that area with either metal or plastic.
3. Patellofemoral Replacement
This can be highly effective for people with chronic kneecap arthritis which replaces only the under-surface of the kneecap
4. Complex Knee Replacement
This procedure is required if there is severe arthritis or if there is an existing two or three knee replacement surgeries.
5. Cartilage Restoration
Sometimes when the knee has a distinct injury in this the area it can be replaced with a living cartilage graft or cells which grow into cartilage.
Knee Replacement Surgery: Conclusion
The other approaches include Computer Assisted Surgery and Minimally Invasive Surgery which aren’t a method of surgery but more like an approach, but this is used in modern science because of reliability.
