  • the condition of the knee joint
  • the patientâs age and activity level

In cases where the damage from arthritis is minimal, and/or if the patient does not have a very active lifestyle, nonsurgical treatments by be tried, including:

  • physical therapy
  • , such as ibuprofen
  • weight loss to reduce pressure on the knee

How Do I Know If I Need Knee Replacement Surgery

You may need surgery if:

  • Your knees are stiff and swollen.
  • There is pain throughout the day, even at rest.
  • Walking, getting up or climbing stairs is difficult and painful.
  • Medication and therapy do not offer enough relief.
  • Knee cartilage is so damaged and worn away that you are walking “bone on bone,” in which the bones of the joint are scraping together.

This is an excellent knee replacement surgery video for those that want to see the real thing. It shows how the surgery is carried out, the steps taken by the surgeon to ensure the minimal amount of bone is removed, the accurate placement of the prosthesis and all the steps taken to prevent infection.

The actual surgery takes approximately two hours, but this video summarizes it down to around ten minutes. You get to see all the different stages of the surgery, as well as how they select the correct size implants.

BEWARE: This is a graphic video – the 20 second introduction with the slightly scary sounding music makes that very clear. It is not for the feint hearted! But it really is a great video for those who want to see exactly what is going to happen.

How Long Is It Before I Can Walk After A Knee Replacement

Most patients progress to a straight cane, walker or crutches within two or three days after surgery. As the days progress, the distance and frequency of walking will increase.

Patients are usually able to drive a car within three to six weeks after surgery and resume most other normal activities by or before six weeks. Complete recuperation and return to full strength and mobility may take four months or more. However, in many cases, patients are significantly more mobile one month after surgery than they were before they had their knee replacement

How Is A Total Knee Replacement Performed

First, the orthopedic surgeon makes an incision in the knee and moves the patella to the side. If are any bone spurs are present, as sometimes occurs in osteoarthritis, they will be removed.

Next, the two menisci between the femur and tibia are removed, as are the anterior cruciate ligament and, in some cases, the posterior cruciate ligament . In some types of knee replacement, the PCL is retained.

During the main phase of the operation, the surgeon cuts and remove cartilage and some bone from the upper part of the tibia and lower sections of the femur. The femoral sections removed are two knobby protuberances called the femoral condyles. The tibia and femur are then be capped with metal implants to create new surfaces for the joint. The surface of the femoral component mimics the shape of the original femoral condyles. If the kneecap has also degraded, the surface on its underside may also be cut away and replaced with a polyethylene implant.

Finally, the various layers of tissue are repaired with dissolvable sutures and the skin incision is closed with sutures or surgical staples. A bandage will be wrapped around the knee and the patient is be taken to recovery.

In some cases, the orthopedic surgeon may employ robotic technologies during the operation. “” rel=”nofollow”> robotic-assisted, knee replacement.)

Ial Knee Replacement Overview

Artificial Knee Replacement

A is also known as unicompartmental knee arthroplasty or unicondylar knee arthroplasty. In this surgery, damaged cartilage and bone are removed and replaced only in one diseased compartment of the knee. This differs from a total knee replacement, in which bone and cartilage from the entire joint are replaced.

Partial knee replacement is suitable for people who experience arthritis only in one compartment of the knee joint, rather than throughout the joint. It can also provide relief from pain and stiffness in some people who have medical conditions that make them poor candidates for total knee replacement surgery.

Not All Hospitals Achieve The Same Results

Animated Knee Replacement Surgery Video

This animated version from Matrix Orthopedics shows an overview of what happens during the different stages of total knee replacement surgery.

It is great way to see what happens but without being too graphic – a good place to start! The video lasts approximately two minutes and there is no sound.

There are a couple of things to note about the surgery shown here. Firstly, it does not show the removal of the cruciate ligaments, but this happens as part of the initial preparations of the bones.

Secondly, it shows the back of the kneecap being replaced, but this is only done if there is patellofemoral arthritis. In cases where there is minimal wear and tear of the kneecap, an implant may not be required. The surgeon will simply remove any osteophytes on the back of the kneecap to leave a smooth and friction free surface.

How Long Does A Knee Replacement Last

Knee replacement implants are expected to function for at least 15 to 20 years in 85% to 90% of patients. However, the implants do not last forever.

After a period of 15 to 20 years, general wear and tear may loosen the implant. Depending on the patient, this may cause no symptoms, or it may cause any of the following:

  • knee instability

When these symptoms arise, orthopedic surgeons recommend having to replace the original implant. Infection, especially, requires a prompt revision surgery. Infection after knee replacement surgery is rare, but a knee replacement implant cannot defend itself from infection if bacteria are introduced to the body. Learn more about the at HSS.

The selection of knee replacement prosthesis design and materials depends on each individual patient. The main implant components are made of metal â usually titanium or chrome-cobalt alloys. The implants are fixated in place either with a cement bonding agent or by osseointegration, in which a porous metal stem extends into the tibia and the patient’s natural bone grows into it. A plastic platform or spacer will be inserted between the tibial and femoral implant surfaces. The spacer is made of polyethylene.

Most femoral components are made of metal alloys or metal-ceramic alloys . The patellar component is plastic . The tibial insert component is also plastic . The tibial tray component can be made of the following materials:

Knee Replacement Recovery Time And Recuperation

Total knee replacement surgery generally takes about 60 to 90 minutes, but you should expect to be in the operating room for over two hours. Rehabilitation will begin within 24 hours of surgery.

The physical therapist will assist you in the following activities:

  • sitting at bedside with your feet on the floor
  • transferring in and out of bed safely
  • walking with the aid of a device
  • climbing stairs with aid of a device

What Is Knee Replacement Surgery

Knee replacement is where portions of the bones that form the knee joint are removed and replaced with artificial implants. It is performed primarily to relieve knee pain and stiffness caused by .
