Living with severe knee pain can make even the simplest tasks—like walking, climbing stairs, or getting out of a chair—feel impossible. When conservative treatments like physical therapy and joint injections no longer provide relief, knee replacement surgery offers a proven path to long-term pain relief and restored mobility.

What Is Total Knee Replacement?
Total knee replacement, also called total knee arthroplasty (TKA), is a surgical procedure in which damaged surfaces of the knee joint are replaced with artificial components. It is commonly performed for patients with advanced knee arthritis who have persistent pain, stiffness, deformity or difficulty with daily activities despite appropriate non-surgical treatment.

Recovery After Total Knee Replacement
Every patient heals at a unique pace, but a standard recovery follows these major milestones:
Day 1 | Surgery & Early Mobility The procedure takes 1 to 2 hours. Guided by a physical therapist, you will stand and take your first steps with a walker a few hours after waking up.
Days 2–3 | Discharge Home You will practice moving safely from bed to chair, climbing a few steps, and managing pain with oral medication before being discharged.
Weeks 1–3 | Range of Motion Physical therapy begins to reduce swelling and improve knee bending and straightening. Stitches or clips are removed around Day 14.
Weeks 6–12 | Many patients gradually return to driving, light activities and independent walking during this period, depending on their individual recovery.
Recovery varies from patient to patient depending on age, medical conditions, fitness, pre-operative deformity and the complexity of surgery.
Results of Total Knee Replacement
Total knee replacement can significantly reduce knee pain and improve mobility, knee alignment and the ability to perform everyday activities. The degree of improvement varies between patients depending on the severity of arthritis, deformity, general health, muscle strength and rehabilitation.
