Replacing a deteriorated, timeworn, or compromised bone with an artificial counterpart is known as knee replacement surgery, or arthroplasty. This intricate procedure entails excising damaged bone and soft tissues from the femur, tibia, and patella, subsequently substituting them with a synthetic joint composed of robust metal alloys and durable polymers.
There are two types of knee replacement:
Total Knee Replacement (TKR): In the total knee replacement process, the complete joint is replaced by an artificial joint. Throughout the complete knee replacement procedure, the top of the thigh bone is removed and replaced by a metal shell. The lower long bone (tibia) was additionally removed and replaced by a metal stem. Knee replacement surgery has its own specific edges and risks.
Partial Knee Replacement (PKR): This procedure is reserved for instances where damage is confined to a single compartment of the knee. PKR involves minimal bone removal and is performed through a smaller incision, rendering it a less invasive alternative to TKR. When the injury or degeneration is localized to a specific region, PKR emerges as a viable option, ensuring a more conservative approach to preserving the knee’s natural integrity.
With any operation, there are some risks as well as some benefits.
In knee replacement surgery, complications are rare but may include:
Knee replacement surgery duration is only one to two hours, and the hospital stay is about 3–6 days.
Knee replacement surgery success rates at India’s best hospitals are 99%.
And the success rate of surgery also depends on the patient’s condition.
