What knee arthritis is, why it develops, how it is treated, and when knee replacement may become the right option.
Understanding your arthritis is the first step toward making the right treatment decisions. My goal is to help you understand what is happening inside your knee, what treatments are available, and when surgery may become the right choice. These are the same conversations I have with patients every day in clinic.
This is one of the most common questions I hear in clinic.
Many people assume there is a certain age or a certain X-ray that tells us it is time for surgery. In reality, neither one makes the decision for us.
Instead, I ask a much simpler question:
"How much is your knee affecting your life?"
Some patients have severe arthritis on X-rays but very little pain. Others have more moderate arthritis yet struggle to sleep, walk, travel, work, exercise, or enjoy time with family.
Before recommending surgery, we usually try appropriate nonsurgical treatments. These may include physical therapy, weight loss when appropriate, activity modification, anti-inflammatory medications, bracing, and injections.
These treatments do not regrow cartilage, but they can provide meaningful pain relief and improve function.
Eventually, however, the patches may stop working. At that point, knee replacement becomes the most reliable treatment because it addresses the damaged joint surfaces rather than only managing the symptoms.
The goal is not to create a perfect knee. The goal is to give you a dependable knee that allows you to return to the activities that matter most.
Do not let your X-rays decide when it is time. Let your quality of life help make the decision.
Many patients worry that they will miss their opportunity to have a knee replacement.
Fortunately, that usually is not the case. Unlike a broken bone or a torn tendon, knee arthritis rarely requires emergency surgery.
However, as arthritis worsens, many people become less active because walking and exercise hurt.
Over time, reduced activity can lead to:
These changes do not prevent a successful knee replacement, but they may make recovery more challenging.
The larger cost of waiting is often the time patients lose avoiding vacations, family activities, exercise, golf, hobbies, or ordinary daily tasks because of pain.
If knee pain consistently limits your life despite appropriate treatment, it may be time to discuss surgery.
Do not wait until you cannot walk. Recovery is often easier when you still have reasonable strength and mobility.
There is no single minimum age for knee replacement.
Some younger patients develop severe arthritis after an injury, previous surgery, deformity, or years of joint damage. Others develop arthritis primarily through aging and genetics.
Modern knee replacements are durable, but a younger patient has more years and potentially more activity to place on the implant. That means younger patients have a greater lifetime possibility of needing another operation in the future.
For that reason, we usually try reasonable nonsurgical treatments before recommending surgery in a younger patient.
However, when arthritis is severe, treatments are no longer helping, and pain is significantly affecting quality of life, age alone should not prevent someone from considering knee replacement.
We do not treat birth certificates. We treat people.
Many healthy patients in their 80s and even their 90s recover very well after knee replacement.
Before recommending surgery, we evaluate your overall health, heart and lung function, medical conditions, medications, mobility, support system, and ability to participate in recovery.
A healthy and active older patient may recover more easily than a younger patient with several poorly controlled medical conditions.
For many older adults, reducing knee pain can help preserve independence, improve balance, maintain walking ability, and make everyday activities safer.
The decision should be individualized rather than based only on age.
Your health and independence matter more than the number on your birthday.
Cartilage is remarkable tissue.
It creates an extremely smooth, low-friction surface while also helping absorb forces with every step.
Once a large amount of cartilage has been lost, the body has very limited ability to replace it.
Many products and treatments claim to regrow cartilage or reverse arthritis. At this time, no injection, supplement, stem-cell treatment, medication, or exercise program has been proven to reliably restore normal cartilage throughout an advanced arthritic knee.
That does not mean nothing can be done.
Arthritis symptoms can often be managed for years with:
When these treatments no longer provide enough relief, knee replacement resurfaces the damaged portions of the joint with smooth metal and plastic components.
We cannot make worn cartilage new again, but we can often help you remain active and comfortable for years before surgery becomes necessary.
I often explain knee arthritis using a road analogy.
When you are young, the road is freshly paved. The cartilage covering the bones is extremely smooth and helps the joint move with very little friction.
Over time, that road begins to wear.
For some people, it is primarily the result of decades of use and genetics. For others, previous injuries, fractures, meniscus damage, ligament injuries, joint alignment, excess body weight, inflammation, or previous surgery may contribute.
As the smooth cartilage becomes thinner, rough areas begin to develop. Those rough areas gradually become larger, much like potholes forming in a road.
Those potholes represent osteoarthritis.
As arthritis progresses, the knee may become painful, swollen, stiff, less flexible, and more difficult to use during everyday activities.
Knee arthritis usually develops from years of accumulated wear rather than one bad day.
Every knee is different. If knee pain is limiting your life, schedule an appointment to discuss your symptoms and treatment options with Dr. Jadye Kee.
