It is a common belief among many patients that after an artificial hip or knee replacement surgery, after 10-20 years of service life, they will need to undergo a bed of secondary surgery or revision surgery, so for young patients, this means that they will need to undergo several revision surgeries in their lifetime, so many doctors who are not very professional will say to young patients, wait until you reach the age of 50-60 years old before you can have a replacement. So even if a young patient is in so much pain that they can no longer work and their life is greatly affected, then such patients will have to wait another 10-20 years before they can undergo the surgery, and they will undoubtedly spend their young adulthood in pain, so what quality of life is there to speak of? Even if a patient has a joint replacement, the surgeon will tell the patient to save on the use of the joint, the patient is afraid of another revision, and lives carefully, can’t travel or participate in sports for fear of another operation, and the sword of revision is always hanging over their head, affecting their whole life, so will the quality of life of such a patient be high? Can you as a joint surgeon accept this reality? Is there a need for revision after arthroplasty and how difficult it is to operate? Two issues need to be clarified here: one is that the concept of the need for revision after 10-20 years of service life is wrong, which is based on the premise of the use of ordinary polymer polyethylene liners (spacers) in the past, and now the use of ordinary polymer polyethylene liners (spacers) for young patients is becoming less and less, if the use of ceramic-to-ceramic or highly cross-linked polyethylene liners (spacers) may be used for the rest of their lives, so the revision is not The second is that although revision surgery is difficult compared to initial replacement, more than 90% of revisions are not very difficult, and this difficulty is relative and is understood differently by doctors with different experiences. Also particularly difficult revisions are often due to too much osteolysis caused by the wear particles of the plain polyethylene, leading to severe bone defects, so the culprit is still the plain polyethylene, so as long as you don’t use the plain polyethylene liner (spacer) you won’t have as many problems.
