Knee replacement, also known as knee arthroplasty, is a surgical procedure where the damaged or diseased parts of the knee joint are replaced with artificial parts. The goal of knee replacement is to relieve pain and restore function in severely diseased knee joints.
When is Knee Replacement Needed?
Knee replacement is typically considered when conservative treatments such as medication, physical therapy, and use of assistive devices like canes have not helped relieve the pain. Conditions that might lead to a knee replacement include osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis.
Types of Knee Replacement Surgeries
There are two main types of knee replacement surgeries: total knee replacement (TKR) and partial knee replacement (PKR). In a TKR, the entire knee joint is replaced, while in a PKR, only one part of the knee is replaced.
The Knee Replacement Procedure
During the procedure, the surgeon removes the damaged bone and cartilage from your thighbone, shinbone, and kneecap, and replaces it with an artificial joint made of metal alloys, high-grade plastics, and polymers.
Recovery After Knee Replacement
Recovery after knee replacement surgery involves a combination of physical therapy, pain management, and gradual return to activities. Most people are able to resume normal activities within 6 weeks to 3 months after surgery.
Risks and Complications
Like any surgery, knee replacement has potential risks and complications. These can include infection, blood clots, implant problems, and continued knee pain. It’s important to discuss these risks with your doctor before the surgery.
Conclusion
Knee replacement surgery can significantly improve quality of life for individuals with severe knee pain or stiffness. By understanding the procedure, its benefits, and potential risks, you can make an informed decision about whether it’s the right option for you.
