How long does a knee implant last?

Despite its high performance, an artificial joint is never equivalent to a healthy natural joint. In the scientific literature, the average risk of a replacement operation is given as a maximum of 1% per implantation year. Thus, many prostheses even last a lifetime. Causes for premature loosening of the artificial joint are, for example

  • Bone quality
  • Accompanying diseases
  • Accompanying factors such as overweight
  • Too much or wrong load
  • Infections
  • Broken bones
  • Pain
What diagnostic procedures are available?

X-ray image (stationary)

The irradiation of body parts with X-rays is shown in images called radiographs or x-rays. Magnetic Resonance Imaging (MRI) MRI is an imaging procedure without radiation exposure that is used to visualize the structures and functions of tissues and organs.

Computer tomography (CT)

Computed tomography is a procedure for the layer-by-layer imaging of bone structures based on X-rays. The examination can be performed quickly and is very precise.


Can one react allergic to a prothesis?

Please inform your doctor in advance about any allergies you may have. He will inform you about risks and alternatives. However, there are now very good material alternatives for potential allergy sufferers. Please also remember to bring your allergy passport and mention existing reactions to medication or latex.


Which form of anesthesia is suitable?

As a rule, admission to the hospital takes place the day before the planned operation. Usually your personal data will then be requested and you will be assigned to the ward and room. An anesthesiologist will then discuss the planned anesthesia with you. Today, artificial knee joints are used both under general anesthesia and with the help of spinal anesthesia.

Spinal anesthesia (partial anesthesia)

In this procedure, an anaesthetic is injected at the level of the lumbar spine to numb the lower half of the body.

General anesthesia (general anesthesia)

In general anesthesia the patient is put into an artificial sleep. Both the consciousness of the patient and his pain sensation are switched off.

What does “minimally invasive” mean?

Today, various minimally invasive procedures are available for knee joint implantation. The aim here is to use as little soft tissue as possible and to avoid damaging it. The advantages of a minimally invasive operation are

  • Faster rehabilitation
  • Reduced pain
  • Hardly any blood loss during surgery
  • No muscle injury or separation



What risk can occur?

In Germany alone, more than 160,000 knee prostheses are implanted annually. This makes the operation one of the most well-known treatment methods. However, as with all operations, knee joint implantation also involves risks. This includes, for example:

  • Vascular/nerve damage
  • Infections
  • Leg length difference with, if necessary, compensation of the opposite side
  • Broken bones
  • Thrombosis
  • Calcifications in the musculature
  • Loosening of implant components
  • Wear and material overload
  • Restricted range of motion
  • Pain
  • Incompatibilities



When do follow-up appointments take place after the operation?

In consultation with your doctor, this should be done twice at 6-month intervals in the first year and once every two years thereafter. Please bring your last X-ray and the implant passport with you. Every follow-up check should be entered in the patient passport. This way you always have an overview. The regular check-ups allow possible complications to be detected very early. If severe pain suddenly occurs, the treating physician must be consulted immediately.

Exercise and sports are not to be avoided in the first 6 months, but there are a few points to consider. After consultation/agreement with your doctor you can start using start with sports. Sports with high stress on the artificial joint (ball sports, as well as sports where there is a higher risk of falling) are less suitable. Cycling and especially e-biking is not recommended until a complete ability to react is restored. Extreme overloading leads to increased stress and wear on the prosthesis and reduces the life expectancy of an artificial joint. Ultimately, this can lead to premature loosening.
