How long do joint replacements usually last?

One of the most frequently asked questions after prosthesis surgery is the lifespan of the prosthesis. Knee and hip prostheses generally have a lifespan of 25–35 years. However, this duration may vary depending on personal factors.

The patient’s age, body weight, physical activity level and post-surgical care are the main factors affecting the lifespan of the prosthesis. In younger and more active patients, the lifespan of the prosthesis may be shorter, whereas in older and less active individuals, the prosthesis may last longer.

What affects implant lifespan?

Among the most common reasons for prosthesis replacement, wear and loosening are the most important factors that shorten the lifespan of the prosthesis. Several personal and surgical factors influence how long a joint replacement continues to function well:

  • Age at surgery and the demands placed on the implant
  • Body weight and overall metabolic health
  • Physical activity level and the type of regular exercise
  • Material properties of the prosthesis and surgical technique
  • Post-surgical care and adherence to medical advice

Signs your implant should be checked

Immediate consultation with a doctor is crucial if there is any pain, swelling or restriction of movement in the prosthetic joint. Regular medical check-ups and X-rays are important for monitoring the condition of the prosthesis and detecting potential problems early.

  • Pain, swelling or warmth around the joint
  • New stiffness or restriction of movement
  • Difficulty walking or completing daily activities
  • Any sudden change in how the joint feels or functions

How to protect your joint replacement

To prolong the lifespan of the prosthesis, it is important to follow the doctor’s recommendations, have regular check-ups and avoid excessive physical activity. While the lifespan of prostheses can be extended with new-generation materials and surgical techniques, it may still be necessary to replace the prosthesis after a certain period of time.

  • Keep the wound area clean in the early postoperative period
  • Follow infection-prevention advice from your care team
  • Avoid heavy lifting and excessive physical activity in daily life
  • Maintain weight control to reduce pressure on the prosthesis
  • Attend regular medical check-ups and imaging as advised
