Implants are made of metal alloys, ceramic material, or strong plastic parts. Up to three bone surfaces may be replaced in a total knee replacement: The lower end of the femur. The metal femoral component curves around the end of the femur (thighbone).
What is the best material for knee replacement?
The metals used in artificial knees are alloys of cobalt-chromium and titanium. The bearing portion of the joint is made of a high-grade, wear-resistant plastic. The metal-plastic bearing combination is the most common type used in knee replacement implants worldwide.
What is the best knee replacement for an active person?
Proper PCL funtion is also essential for athletic movements such as jumping, pivoting and quick stopping and starting. As opposed to the ACL, the PCL does not necessarily have to be removed in knee replacement surgery. Implant designs that preserve the PCL are called Posterior Cruciate Ligament Retaining implants.
What kind of knee replacements are there?
The four main types of knee replacement surgery are:
- total knee replacement.
- unicompartmental (partial) knee replacement.
- kneecap replacement (patellofemoral arthroplasty)
- complex or revision knee replacement.
What is the newest procedure for knee replacement?
Minimally invasive total knee replacement is a variation of this approach. The surgeon uses a shorter incision and a different, less-invasive technique to expose the joint—with the goal of reducing postoperative pain and speeding recovery.
What is the newest technology in knee replacement?
“The cementless knee replacement, which is FDA-approved for use with a robotic system, combines two of the most recent knee replacement advancements into one high tech procedure that aims to benefit patients.”
What happens if you don’t get a knee replacement?
risk of deformities developing inside and outside the joint. risk of muscles, ligaments and other structures becoming weak and losing function. increased pain / inability to manage pain. increased disability/lack of mobility.
How long does a titanium knee replacement last?

What is the alternative to knee replacement surgery?
Regenerative Stem Cell Therapy
Stem cell knee therapy is becoming a popular alternative to knee replacement surgery. Through a method known as autologous transplantation, the cells are extracted from the patient’s bone marrow or fatty tissue, processed, and immediately injected into the damaged knee.
What happens if you don’t do physical therapy after knee surgery?
Decreased blood flow to the area can negatively affect healing at the surgical site. Muscles can weaken and atrophy if they go too long without use. Not learning or relearning proper movement can put stress on the knees.
Is stem cell better than knee replacement?
When you choose stem cell therapy as an alternative for knee replacement, however, most of those risks evaporate. The biggest risk you’ll face is the risk of infection, but that’s extremely rare because the procedure is minimally invasive. The benefits of stem cell treatment for knees, on the other hand, are huge.
