Knee replacement surgery, or knee arthroplasty, involves replacing a damaged or diseased knee joint with an artificial implant to relieve pain and restore function. The procedure typically starts with anesthesia, followed by a surgical incision to access the knee joint. The damaged surfaces of the femur, tibia, and sometimes the patella are removed, and the prosthetic components are carefully implanted to mimic the natural movement of the knee. After the procedure, the incision is closed, and the knee is stabilized with a splint or brace. The benefits of knee replacement surgery are significant, including relief from chronic pain, especially due to osteoarthritis or injury, improved mobility, enhanced quality of life, and better joint stability.
Knee replacements are designed to last many years, often between 15 to 25 years, and they also help correct joint deformities such as bow-leggedness. Recovery typically involves a hospital stay of 1-3 days, followed by pain management and physical therapy to restore movement and strength. Full recovery can take 6 months to a year, during which time patients gradually regain their activity levels.
Physical therapy plays a crucial role in regaining strength, flexibility, and function, and while the knee replacement provides long-term benefits, patients should avoid high-impact activities. Regular follow-up appointments are necessary to monitor the implant’s function. Overall, knee replacement surgery is a highly effective option for those with severe knee pain, offering long-lasting relief and an improved quality of life when followed by proper rehabilitation.
