When To Get Knee Replacement?

Determining when to transition from conservative treatments to total knee arthroplasty is a pivotal decision for anyone suffering from chronic joint pain. Board-certified orthopaedic surgeon Dr. Cory Calendine of the Bone and Joint Institute of Tennessee emphasizes that while knee replacement is an elective procedure, it is highly effective for those whose quality of life is restricted by osteoarthritis. Key indicators that it may be time for surgery include persistent pain that interferes with daily mobility, a lack of relief from non-invasive options like injections or physical therapy, and having a solid postoperative support system in place. Discover the essential questions to ask yourself—and your surgeon—to decide if robotic-assisted knee reconstruction is the right step for your joint health.

Knee replacement, or ‘knee arthroplasty’, is an advanced orthopedic surgery that has helped thousands of people regain their movements and experience dramatic pain relief. Arthritis is common. Most people manage to deal with it as they get older. So when to get knee replacement? The problem is neither life-threatening nor limb-threatening, so it is considered an “elective” surgery, but it is very effective at offering patients joint pain relief and return to an active lifestyle.

How do I know when to get knee replacement?

There is no single answer suitable for every patient. Knee replacement is a very personal decision, in which case the benefits and risks need to be considered. Before deciding on a knee replacement, there are some questions to ask yourself.

Are you physically eligible for the procedure? Do you have knee pain due to arthritis? Most people undergoing knee arthroplasty suffer from osteoarthritis due to years of wear of the cartilage (which softens the tips of the bones and provides lubrication against friction). When cartilage is damaged, the bones rub against each other painfully, creating osteophytes that can further impede smooth joint movement. Total knee arthroplasty removes damaged bone and cartilage and replaces the joint with a prosthesis that behaves like a natural knee.

Have you tried conservative treatment? There are many treatments for arthritis available. It ranges from very conservative applications such as heat and cold applications to medications and injections of corticosteroids. Many people find relief with these treatments. Before considering surgery, it makes sense to see if one of these less-invasive treatments is effective for joint symptom relief.

Will your life improve after knee replacement? Age is not an important factor in the success of knee replacement, but there are some cases in which the patient is in experiencing pain that interferes with mobility and daily activity. If knee replacement does not offer major improvement in your quality of life, it may not be worth the risk and cost. If joint pain is severe, mobility is restricted, constant, and arthritis is the only cause, it may be time for a knee replacement.

Can you afford to have a knee replacement? The cost to you as a patient is not only the cost of the procedure, but also the time spent during recovery. Depending on your type of work, you may go be out for 6 to 12 weeks before returning to work with your new knee. In addition to financial concerns, there are risks associated with any surgery. It is important to carefully discuss possible short-term pain and other risks (such as infections and blood clots) with your surgeon.

Is your overall health good? The risk of complications and the unlikely possibility that a patient is not satisfied with the outcome of the surgery is closely linked to other pre-existing health conditions. Some of these that can increase complications include obesity, diabetes, chronic pain from other conditions, and depression. Your surgeon will tell you about these seemingly irrelevant conditions that can reduce the success rate of knee replacements and complicate a relatively safe knee replacement procedure.

Do you have support? It’s scary to give up control over the time it takes to recover from major surgery. Is there a support system at home or in your community? It is important prior to any joint replacement surgery to have a postoperative plan in place that includes a plan for assistance with driving and getting-around immediately following your procedure. Knee replacement surgeries are increasingly being done as outpatient or same-day surgeries, allowing patient to return home to the comfort of their own bed much sooner. Shortened hospital stays have made it even more important to have a structured support system when returning home.

FREQUENTLY ASKED QUESTIONS

Common Questions From Readers

What is the most common reason for needing a knee replacement?
The most frequent cause is osteoarthritis, a degenerative condition where the protective cartilage on the ends of the bones wears away. This results in painful bone-on-bone friction and the development of osteophytes (bone spurs), which can significantly impede smooth joint movement and daily activity.
Yes, it is standard practice to explore conservative treatments first. Options range from simple heat and cold applications to medications and corticosteroid injections. Surgery is typically recommended only when these less-invasive methods no longer provide adequate symptom relief.
Age is not the most important factor in the success of the procedure. Instead, Dr. Calendine focuses on your quality of life and physical eligibility. If joint pain is severe, constant, and restricts your ability to perform daily tasks, surgery may be a viable option regardless of age, provided your overall health is good.
Recovery is a significant investment of time. Depending on the physical demands of your job, you may need to plan for 6 to 12 weeks of recovery before returning to work. It is also essential to have a postoperative plan for assistance with driving and household tasks immediately following the procedure.
Yes, your overall health is closely linked to surgical outcomes. Pre-existing conditions such as obesity, diabetes, and chronic pain from other sources can increase the risk of complications or impact patient satisfaction. Dr. Calendine will review your medical history to ensure you are optimized for a safe and successful procedure.
