Double Knee Replacement Surgery: What Is It?
A double knee replacement (DKT) is a surgical procedure where both knees are replaced with one joint from another person’s body. A DKT involves two surgeons performing the operation at the same time, which means they will need to have very good skills in their respective fields. The surgeon must be able to perform complex surgeries such as removing bone fragments or repairing torn ligaments and tendons without any problems. They must also be able to do it quickly and safely. If the surgeon cannot perform these tasks well, then the whole procedure could fail and lead to permanent disability.
The second part of the procedure involves attaching new joints to replace those damaged during the first stage of surgery. The doctors will attach nerves, muscles, tendons and other connective tissues so that they can function normally again after having been severed during the initial surgery.
Surgeons usually perform DKT when there is no suitable donor left over from a deceased patient. When someone dies, all the bones in their body are removed and placed into a freezer until they are needed later. Then, surgeons take pieces of tissue and blood vessels taken from the person’s arm or leg and use them to create a new limb using skin grafts or muscle cells taken from elsewhere in the body.
How Is A Double Knee Replacement Done?
The first step in performing a DKT is to make an incision at the front of the knee and carefully removing the damaged cartilage and torn muscles. The surgeon then assesses how much bone needs to be removed from the tibia and femur before attaching a donor joint. During this part of the surgery, it is important to prepare the leg properly so that it receives as much blood as possible.
The second part of the procedure involves attaching the new joint. This is done by cutting the tibia and femur further until a flat surface is created to support the new joint. This means that the leg will be slightly shorter after surgery, but will heal at a faster rate. The surgeon then drills holes into the bones to allow for screws to be installed to hold the new knee together.
The new knee is then attached with screws and tightened appropriately.
Once the new joint has been installed, the surgeon will sew the skin back together and apply bandages. The patient will then have to rest while the new joint heals itself over time. It can take up to a year for full recovery, but most patients can walk with the aid of a crutch after only a few weeks. Physical therapy is recommended to strengthen the muscles in the leg and make sure that the knee is working properly after surgery.
What Are The Potential Risks?
There are various risks associated with DKT and these include:
Incorrect bone length
Damage to blood vessels or nerves around the new joint
Unexpected bleeding complications
Reaction to anesthesia (rare)
Incorrectly sized implants or prosthesis.
As you can see, there are various risks involved in this type of surgery that cannot be eliminated. There is also the possibility that the new joint could wear out quicker than the original one and require surgical replacement.
The surgeon should explain all these risks before you decide to go ahead with the procedure so that you are fully aware of what might happen during and after surgery. You should not feel afraid to ask any questions about the procedure or anything you do not understand. The importance of having this information cannot be overstated because it will help you to make an informed choice about what you want to do.
Is DKT Right For You?
If you have severe knee pain, limited mobility and trouble with day to day activities then a double knee transplant might be the answer you are looking for. DKT offers a great improvement in quality of life and makes many daily activities easier to perform.
However, as with any surgery there are risks involved and you need to make sure that you are in a good mental and physical condition before going ahead with DKT. It is essential that you perform some research about the procedure so that you understand everything fully and can decide whether it is right for you.
If you do decide to have DKT surgery, make sure you choose a highly skilled surgeon who is experienced in this field. You can do this by asking for recommendations or doing some research online to see how other patients have gotten on with a certain doctor. Make sure you are completely honest with your surgeon and only have the surgery if YOU feel ready and able to go through with it. Above all, you should feel positive and excited about the prospect of DKT improving your life in the future.
