knee replacement problems after years


Knee replacement, which doctors call knee arthroplasty, has become very popular these days.

Sometimes a surgeon may require a complete arthroplasty, and sometimes a partial knee arthroplasty is needed.

Will knee arthroplasty cause you problems in the future?

How long does an artificial knee joint last and what complication can it cause in the following years of surgery?

Knee replacement or knee arthroplasty:

In this common surgery, metal or plastic prostheses are used and these prostheses replace the kneecap or part of your knee joint.


The surgeon makes an incision about 20 cm long on the skin of your knee, observes the knee closely and removes the damaged parts from the knee, now replaces them with a prosthetic prosthesis.


What is the material of prostheses in knee replacement?

  • Metal alloys
  • Plastic
  • and standard polymers


The type, material and size of the prosthesis will be determined by your surgeon according to the sex and type of injury and the severity of the knee joint damage and age.

A very important point in determining the type and material of knee prosthesis is the amount of daily activity and job.


The knee prosthesis has a metal part that the orthopedic surgeon will attach to the lower surface of the femur. Bone powder is used to make this connection.

Sometimes it is necessary for the surgeon to flatten a portion of the adjacent bone to fit the prosthesis so that the prosthesis fits snugly. During the operation, your knee is bent and straightened by your surgeon to ensure that the knee joint is easily moved in its range of motion. Now the cut skin is sutured, you are transferred to the ward after recovery and stay in the hospital for one or more days so that you can walk and leave the hospital on your own.


By relieving the short recovery period we mentioned above, you will return to a life without pain.


But can this knee replacement be a problem in the years to come?

Both the type of prosthesis used and the technique of knee replacement surgery, as well as the general health and underlying diseases of the individual, play a role in determining the problems and complications of future years of knee arthroplasty.


Doctors believe that if you use the prosthesis properly, your prosthesis will last fifteen to twenty-five years.


Proper use means that you do not sit on two or four knees and do not put too much pressure on your knee prosthesis.

All of the above behaviors can shorten the life of your knee prosthesis, because plastic or metal knee prostheses are not as durable as a normal knee joint and will wear out over time.


What should we pay attention to in order to maintain the durability and efficiency of your knee prosthesis?

To maintain the durability and efficiency of your knee prosthesis, pay attention to the following points:

  • Do not forget the annual meetings to visit your surgeon.
  • Do not jump on your knees, do not walk on uneven surfaces, do not wear perfectly flat shoes or heels with more than one inch.
  • Avoid gaining weight.
  • To strengthen the supporting muscles of the knee, such as the quadriceps and hamstrings, be sure to do standard exercises daily.
  • Do not go up and down stairs.
  • Do not do strenuous exercise.
  • It is best to use a cane or walker, especially in the first few weeks.
  • It is recommended that you avoid running, cycling and driving long distances for the first few months after surgery.


Knee arthroplasty is one of the most successful surgeries in medicine. Ninety percent of people recover completely after surgery and about ten percent need reoperation.


What makes knee arthroplasty surgery unsuccessful?

The following points can make surgery unsuccessful:

  • Lack of surgeon skills
  • Failure to comply with sterilization conditions during surgery
  • Performing surgery on people who do not have the right conditions to undergo surgery, such as people who are prone to infection or delayed wound healing, or people with diabetes
  • Non-observance of health points and medical recommendations by the person after discharge
  • Non-follow-up of physiotherapy courses by the operated person
