Knee replacement surgery (knee arthroplasty) replaces damaged, arthritic parts of the knee joint with artificial implants to relieve pain, correct deformity and restore mobility. At Noida Orthopedic Clinic, Dr. Amit Aggrawal performs total and partial knee replacement using modern, minimally invasive techniques so you can walk comfortably again — often within days of surgery.

Knee replacement is usually advised when knee pain from osteoarthritis, rheumatoid arthritis, or old injury limits everyday activities — walking, climbing stairs, sitting cross-legged or sleeping — and medicines, physiotherapy and injections no longer help. Typical signs include persistent knee pain, bow-leg or knock-knee deformity, grinding sensations, and stiffness that restricts bending.

In total knee replacement, all three compartments of the knee are resurfaced with implants. In partial (unicompartmental) knee replacement, only the damaged compartment is replaced — preserving healthy bone and ligaments, with a more natural feel and faster recovery. After a detailed clinical and X-ray evaluation, Dr. Amit Aggrawal recommends the option best suited to your age, activity level and degree of arthritis.

Most patients stand and walk with support within 24–48 hours of surgery. A structured physiotherapy program restores bending, strength and balance over 4–6 weeks. Most people return to routine activities in 6–8 weeks and to low-impact sports like cycling and swimming within 3–4 months. Modern implants typically last 15–20 years or more.
