What are the different types of below the knee prosthetics?

Below Knee Prosthesis

  • The Preparatory Prosthesis.
  • The Patella-Tendon Weight-bearing Prosthesis (PTB)
  • Total-Surface Bearing Prosthesis.
  • A Joint-Corset Prosthesis.

What is prosthetic knee joint?

A prosthesis is a device designed to replace a missing part of the body, or to make a part of the body work better. The metal prosthetic device in knee joint replacement surgery replaces cartilage and bone which is damaged from disease or aging.

How many types of prosthetic legs are there?

Types of lower-limb prostheses “There are over 200 different prosthetic feet and 75 different prosthetic knees on the world market,” Dr. Uustal says.

How do prosthetic knees bend?

Hydraulic and pneumatic knees allow adjustment of walking speed by the use of hydraulics (either liquid or air) within the knee. As a person’s walking speed increases or decreases, the hydraulics adjust to control the speed at which the shin of the prosthesis swings forward and bends backward.

How many hours a day can you wear a prosthetic leg?

Wear the prosthesis for a maximum of 2 hours, with up to 1/2 hour of that standing and/or walking. These amounts are maximums, and need not all be done at once. Examine the limb after every hour of wearing, and/or after every 15 minutes of standing or walking.

What is a polycentric knee?

Product description. It is a polycentric prosthetic knee joint, which mimics the movement of a normal knee joint while walking. At the same time, it provides stability during the weight-bearing phase to ensure the person can walk with their artificial limb without falling.

How does a polycentric knee work?

Polycentric knees are suitable for a wide range of amputees. A standard polycentric knee has a simple mechanical swing control that provides an optimal single walking speed; however, many polycentric knees incorporate fluid (pneumatic or hydraulic) swing control to permit variable walking speeds.

Are prosthetic legs painful?

Phantom limb pain, or pain that seems to come from the amputated limb, is a very real problem that you may face after an amputation. “About 80% of people with amputations experience phantom limb pain that has no clear cause, although pain in the limb before amputation may be a risk factor,” says Keszler.

Can a double amputee walk again?

Any amputation is life-altering, but people with bilateral above-knee amputations face a particularly complicated process of physical and emotional rehabilitation. The long-term goal is usually being able to walk again with prosthetic legs.

Can you wear a prosthetic leg all day?

Overdoing it and not following the schedule and instructions from your prosthetist can result in pain and possible injury. Once you have completed the wearing schedule, you can wear the prosthesis all day, but never at night while sleeping. Will I need a wheelchair or crutches?

Can prosthetic legs bend at the knee?

When weight is placed on the prosthesis, the knee will not bend until the weight is displaced. This system functions as a constant-friction knee during leg swing but is held in extension by a braking mechanism as weight is applied during stance phase. This knee is a common choice for older or less active amputees.

What are the best knee implants?

Titanium and its alloy Titanium Cobalt are both used in best knee replacement implant. It has the same properties as Chromium, as well as being more elastic, which is favorable for the bone which surrounds the implant.

What are the different knee replacement options?

There are three main types of a total knee replacement: non-constrained, semi-constrained, and constrained. The most common knee replacement surgery is a non-constrained replacement, a form of total replacement.

What is the best knee replacement implant?

For most knee replacements, a custom implant tailored to each patient is the best option. The company that makes these is Conformis (www.conformis.com). This technology is the best design today.

What are the different types of knee replacement procedures?

Types of knee replacement approaches Traditional surgery. Minimally invasive surgery. Computer-assisted surgery (CAS) Increasingly, surgeons are also turning to computer-assisted methods for both TKRs and PKRs involving both traditional and minimally invasive procedures.
