Modern knee replacements generally work well and are very durable. Failure rate is very low and most of them will last 20 years. However, there is a small failure rate and a revision of the old knee replacement may eventually be required.
Failure is usually associated with pain, which gradually gets worse. It is therefore essential that you see your surgeon if you have persisting pain after a knee replacement.
Causes of failure include: aseptic loosening (gradual wear and loosening), infection, improper positioning or alignment of prosthesis leading to early loosening, fractures around the knee replacement.Revision of knee replacement is specialist surgery requiring great skill and experience on part of your surgeon. Results are very satisfactory, as modern revision implants have been very thoughtfully designed. Unfortunately, revision surgery is very expensive and can cost the patient two to three times that of their primary knee replacement surgery. Therefore, getting your knee replacement right the first time from a good surgeon is essential to prevent later problems.
