Total knee replacement (total knee arthroplasty) is one of the most effective treatment methods for advanced knee arthritis. The primary goal of surgery is to reduce pain and restore knee function by replacing damaged joint surfaces with artificial implants. Millions of knee replacements are successfully performed worldwide each year.

Physical therapy begins in the first days after surgery. In the early period, priorities include regaining knee mobility, quadriceps muscle activation, and edema control. Most patients can walk with assistive devices within 1-2 days after surgery. Hospital stay is typically 2-4 days.

The first 6 weeks after surgery is a critical period for prosthesis stability and tissue healing. Regular adherence to the physical therapy program and performing prescribed exercises at home are essential. Most patients can walk without a cane within 6-12 weeks.

In the long term, patients can comfortably engage in low-impact sports such as walking, swimming, cycling, and golf. High-impact activities such as running, jumping, and heavy contact sports should be avoided. Modern prostheses demonstrate durability of 20-25 years or more with proper use. Regular annual check-ups are important for the long-term longevity of the prosthesis.
