Knee replacement surgery, also known as knee arthroplasty, involves removing damaged or worn-out surfaces of the knee joint and replacing them with artificial components. This procedure is typically recommended for patients with severe arthritis or significant knee injury that affects their daily activities and quality of life.

Candidates for knee replacement surgery are usually individuals who suffer from chronic knee pain and stiffness due to osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis. When non-surgical treatments such as medications, physical therapy, and lifestyle changes fail to alleviate symptoms, knee replacement surgery may be considered.

Recovery time varies from patient to patient but generally includes a hospital stay of 3-5 days followed by several weeks of physical therapy. Most patients can resume normal activities within 6-12 weeks, although complete recovery and maximum improvement can take up to a year. Adhering to post-operative care instructions and physical therapy is crucial for a successful recovery.

Like any major surgery, knee replacement surgery carries potential risks, including infection, blood clots, implant loosening, and nerve or blood vessel damage. However, these complications are relatively rare, and the procedure has a high success rate. Your surgeon will discuss these risks with you and take steps to minimize them.

Knee implants typically last between 15-20 years, although some may last longer with proper care and activity modifications. Advances in surgical techniques and materials continue to improve the longevity of knee implants. Regular follow-up appointments with your orthopedic surgeon are essential to monitor the condition of the implant and ensure long-term success.
