Knee replacement surgery, also known as knee arthroplasty, is a medical procedure where a damaged or deteriorated knee joint is replaced with an artificial implant. This surgery is designed to restore mobility, reduce pain, and improve overall knee function.
Who Needs Knee Replacement Surgery?
This procedure is typically recommended for patients experiencing:
Severe osteoarthritis or rheumatoid arthritis
Chronic knee pain that limits daily activities
Stiffness and swelling that does not improve with medication or therapy
Knee deformities (such as bowing or instability)
How Does Knee Replacement Work?
During the surgery, the damaged bone and cartilage are removed and replaced with a metal and plastic prosthesis that mimics the natural knee joint. The procedure involves:
Precision removal of damaged joint surfaces.
Placement of the artificial implant for smooth movement.
Securing the prosthesis for long-term stability.
Advancements in Knee Replacement Surgery
Modern techniques have improved recovery and success rates, including:
Minimally invasive surgery (smaller incisions, faster healing)
Undergo physical therapy to regain strength and flexibility.
Experience full recovery in 6–12 weeks, with continued improvement over months.
Benefits of Knee Replacement Surgery
Significant pain relief
Restored mobility and flexibility
Improved quality of life
Long-lasting results (15–20 years for most implants)
