Knee replacement surgery, also known as knee arthroplasty, is a surgical procedure to resurface a knee damaged by arthritis or injury. Metal and plastic parts are used to cap the ends of the bones that form the knee joint, along with the kneecap.

The surgery has become one of the most successful procedures in all of medicine, with over 90% of patients experiencing significant pain relief and improved mobility.

Types of Knee Replacement

There are several types of knee replacement procedures. Total knee replacement involves replacing both sides of the knee joint. Partial knee replacement involves replacing only one side.

Comparison of Knee Replacement Types

Type	Duration	Recovery	Success Rate
Total Replacement	1-2 hours	3-6 months	95%
Partial Replacement	1 hour	4-6 weeks	90%
Revision Surgery	2-3 hours	6-12 months	85%

The Procedure

During the surgery, the surgeon makes an incision over the knee, moves the kneecap aside, and removes the damaged joint surfaces. The artificial joint is then attached using bone cement or a press-fit technique.

Knee replacement surgery has transformed millions of lives, allowing patients to return to activities they thought were no longer possible.

ℹ️Key Takeaway

Most patients can begin walking with assistance within 24 hours of surgery. Physical therapy is crucial for optimal recovery and should begin immediately.
