Preparing patients for a knee replacement: the procedures

By PeekMed on September, 29 2016

A knee replacement will be performed when the knee is severely damaged mostly caused by arthritis or injury. It works when it becomes hard for the patient to do daily activities such as climbing stairs or simply walking.

If a medicine or using walking supports stop working, a knee surgery needs to be consider.

A joint replacement is a safe and effective surgery to relieve pain and correct leg deformity.

You need to explain to your patient the procedures that you will be taken and that a knee replacement (mostly known as arthroplasty) requires four basic steps:

1. Preparing the bone. The cartilage surfaces, at the ends of femur and tibia, are removed along with a volume of underlying bone;
2. Position the metal implants. The removed cartilage and the bone are both replaced with metal components that reconstruct the surface of the joint. It’s supposed that you “press-fit” the metal components into the bone;
3. Resurface the patella. Depending on the case, you may not need to perform this step, but if you do, the undersurface of the patella (most known ad kneecap) is cut and reformed with a plastic button;
4. Insert a spacer. A medical-grade plastic is introduced between the metal components and create a smooth gliding surface.

However, a choice on having a knee replacement should be a cooperative decision between you and the patient.

There are a number of reasons who benefit people with knee related problems, to have a knee surgery.

There are no age or weight that can lead for a total knee replacement. Approvals for this type of surgery are calculated on the patient’s pain and difficulties.

On the operation room, the patient needs to be into either general or epidural anesthesia, then a  cut is made in the front of the knee and it so it begins the four basic procedures.

You may ask your patient to see their primary doctor so you can have access to their general health before the surgery. They will be able to identify any previous problems which may interfere with the surgery. If the patient has more extensive health problems an intensive evaluation may be crucial before the surgery. To help plan the procedure you may also need to ask for some pre-operative tests such as blood tests or an electrocardiogram.

If the results show that your patient is in general healthy, they may be performed as an outpatient, which means that they don’t need to spend the night or the day at the hospital and can return home right away.

It is also important to know if your patient takes any medication. They may need to stop days before the surgery.

A total knee replacement should last between 15 and 20 years. However it is likely for your patient to still have some difficulties walking or bending your knee and this can be difficult because of the scar.

There is a Knee Congress taking place in Viseu (Portugal) on 2016 October 1st organized by the Portuguese Society of Arthroscopy and Traumatology, where professionals in the field will present their views on surgery procedures to the knee. It might be interesting for you to attend.

The recovery for this kind of surgery depends on the gravity of the knee damage. It is important for your patient to keep on going to the doctor’s appointments so they keep follow up on their surgery.
