Understanding Knee Replacement Surgery
It’s essential to understand how long does knee replacement last before proceeding with the surgery.
When arthritis or injury severely damages the knee, an artificial joint can offer a new lease on life. This procedure, known medically as arthroplasty, aims to restore mobility and eliminate pain.
What is Knee Replacement?
Knee replacement surgery involves removing a damaged or diseased joint. Surgeons implant an artificial prosthesis made from metal and plastic components. This artificial joint mimics the natural hinge action of your knee.
The smooth articular cartilage that cushions your bones can wear down over time. When it’s gone, bone grinds on bone, causing significant discomfort. Arthroplasty replaces these worn surfaces to create smooth movement again.
Types of Knee Replacement Procedures
Not all procedures are the same. The two main surgical approaches are:
- Total Knee Replacement (TKR): This common surgery replaces both sides of the knee joint.
- Partial Knee Replacement (PKR): This option focuses on only one damaged compartment of the joint.
The knee joint itself is a complex hinge connecting your thigh bone (femur) to your shin bone (tibia). Understanding these options helps you have an informed discussion with your orthopedic specialist about the best path forward.
Overview of Knee Replacement Durability
Research shows that how long does knee replacement last varies widely among individuals.
Durability statistics for knee implants have evolved significantly over the past few decades. We now have a clearer picture of what patients can realistically expect from their prosthetic joint.
