Every patient is different, and individual results will vary. There are risks and recovery times associated with surgery. Individual results and activity levels after surgery vary and depend on many factors including age, weight and prior activity level. There are risks and recovery times associated with surgery and there are certain individuals who should not undergo surgery. Only a physician can tell you if this product and associated procedure are right for you and your unique circumstances. Please consult with a physician for complete information regarding benefits, risks and possible outcomes.

If you’re dealing with severe knee pain from osteoarthritis, rheumatoid arthritis, or traumatic arthritis, knee replacement surgery might be the right solution. When other treatments like physical therapy or injections stop working, it’s time to consider a total knee replacement.
Not at all! While knee replacement is commonly associated with older patients, younger individuals with less advanced arthritis often experience better outcomes. If your knee pain is holding you back, it’s never too early to explore your options.
Before surgery, it’s important to get your body and home ready. Eat healthily, stay active, and make your living space knee-friendly by installing safety rails, clearing trip hazards, and preparing meals in advance. Your surgeon will give you a full list of tips and tricks to make your recovery smooth.
During surgery, the damaged parts of your knee are replaced with artificial components made of metal and plastic. These parts are designed to mimic the movement of a natural knee, helping you move without pain post-surgery.
After surgery, you’ll follow a rehab plan to help you regain strength and mobility. Pain management will be discussed with your surgeon, and most patients return home after a short hospital stay. You’ll be back to doing what you love, pain-free, in no time!
Yes! The decision to undergo knee replacement surgery should involve you and a trusted doctor. It’s not something to rush into, but if you’re experiencing persistent pain and reduced mobility, it might be time to start the conversation with your healthcare provider.
If you’re struggling with severe pain, stiffness, chronic inflammation, or difficulty walking upstairs, and other treatments haven’t worked, it might be time to consider knee replacement surgery. Talk to your doctor about your symptoms to see if it’s the right choice for you.
