Knee replacement surgeries are common procedures for people who suffer from chronic knee pain due to arthritis or injury. This surgical intervention provides relief and restores their functionality, allowing people to return to their daily activities. But one of the most common questions asked by people undergoing this procedure is: how long do knee replacements last? Before addressing this question, it's essential to understand what a knee replacement is and how long it lasts.
A knee replacement, also known as knee arthroplasty, is a surgical procedure where the damaged part of the knee joint is replaced with artificial parts made of metal and plastic materials. During the surgery, the orthopedic surgeon removes the damaged parts of the thigh bone, shinbone, and kneecap to replace them with the artificial components. The artificial parts mimic the natural function of the knee, helping people to regain their mobility and reduce pain in the affected area.
The longevity of knee replacements depends on various factors, including the patient's age, activity level, weight, and medical condition. Generally, knee replacements can last up to 15-20 years, but not everyone experiences the same results. Factors such as heavy physical activity, obesity, infection, and abnormal alignment of the leg may cause accelerated wear and tear of the artificial components, leading to the need for a revision surgery. Therefore, it's essential to take care of the knee after the surgery and follow the orthopedic surgeon's postoperative instructions to ensure the longevity of the new implant.
One way to extend the lifespan of knee replacements is to maintain a healthy weight and remain physically active with low-impact exercises like swimming, walking, and cycling. These activities help build muscle strength around the knee joint, reducing the stress on the implant. Additionally, avoiding high-impact activities such as running or jumping can also help prolong the longevity of knee replacements.
It's also crucial to detect and treat any potential infection in the knee immediately after surgery since infections can cause severe damage and shorten the lifespan of the implant. Regular medical checkups and X-rays are necessary to ensure that the knee implants are in good condition. If any problems or changes are detected early, the orthopedic surgeon can take the necessary steps to prevent further damage and increase the lifespan of the knee replacement.
In conclusion, knee replacements can last up to 15-20 years, but the lifespan may vary depending on the individual's health status, lifestyle, and other factors. To ensure a long-lasting knee replacement, it's essential to maintain a healthy lifestyle, avoid high-impact activities, detect and treat any infection or abnormalities early, and attend regular medical checkups. If you're considering knee replacement surgery or have undergone one, it's crucial to follow the orthopedic surgeon's instructions and take care of your knee to restore your mobility and improve your quality of life.
