Revision knee replacement, as explained by Bradford S. Waddell, MD, refers to a second surgical procedure performed on a knee joint that has previously undergone replacement. Initially, most knee replacements failed due to wear and tear of the plastic components used in the surgery. However, with the introduction of modern plastics in the early 2000s, the durability of knee replacements has significantly improved, reducing the frequency of failures attributed to worn-out plastic. Revision surgeries can range from simple replacements of the plastic spacer to more complex procedures where all components of the knee replacement must be changed due to loosening or other issues.
Waddell notes that modern knee replacements mainly fail due to loosening of the components, infections, or bone fractures above or below the implant. Despite these challenges, advancements in surgical techniques, anesthesia, and pain management have made revision surgeries less daunting for patients, often resulting in a smoother recovery than their initial surgery.
The establishment of joint replacement registries across various countries has provided valuable data on the longevity and failure rates of knee replacements. According to registry data, there is a 5% chance of needing a second surgery within 20 years of the initial replacement, equating to a 0.25 to 0.5% annual cumulative risk. This information helps in understanding the long-term outcomes and risks associated with knee replacements, which is particularly relevant as the age of patients undergoing knee replacement surgery decreases.
