1. How long does it take to feel results?
Most users report noticeable pain relief within the first 1-2 weeks of daily use. However, everyone's body is different. Some people feel improvement after their very first session, while others may take 3-4 weeks to experience significant change. We recommend using FlexKnee Relief™ for 15-30 minutes daily for at least 30 days to give your knees the consistent therapy they need to heal properly. Remember, you're backed by our 60-Day Money-Back Guarantee, so you have plenty of time to experience the benefits risk-free.
2. Will this actually work for MY type of knee pain?
FlexKnee Relief™ is designed to help with the most common types of chronic knee pain, including osteoarthritis, general stiffness and inflammation, pain from old injuries or overuse, muscle tension around the knee, and post-surgical recovery support. If your knee pain is caused by poor circulation, inflammation, or muscle fatigue (which accounts for the vast majority of chronic knee pain cases), this device can help. However, if you have severe structural damage, acute injuries, or specific medical conditions, we recommend consulting with your healthcare provider before use.
3. Is it difficult to use? I'm not tech-savvy.
Not at all! FlexKnee Relief™ was specifically designed with simplicity in mind. There's just one power button and easy controls to adjust heat and massage intensity—no complicated apps, no confusing menus, just straightforward operation. Our user manual includes large print with step-by-step pictures, and most people master it in under 60 seconds. If you can use a TV remote, you can use FlexKnee Relief™. We've intentionally kept it simple so you can focus on feeling better, not figuring out technology.
4. What if it doesn't fit my knee?
The adjustable wraparound design fits knee circumferences from 12" to 22", which covers 99% of adults regardless of size. The flexible, medical-grade material contours to your unique knee shape, ensuring full therapeutic contact and comfort. The straps are easy to adjust and secure with strong Velcro, so you can customize the fit to be snug but never restrictive. If for any reason the fit isn't right for you, you're protected by our 60-Day Money-Back Guarantee—simply return it for a full refund.
5. How is this different from heating pads, braces, or other massagers I've tried?
Great question—this is what makes FlexKnee Relief™ unique. Regular heating pads provide passive warmth but don't actively improve circulation or reduce inflammation. Knee braces offer support but do nothing to heal the underlying tissue. Generic massagers might feel good temporarily but lack the targeted thermal therapy needed for deep joint relief. FlexKnee Relief™ combines both heat AND rhythmic compression massage in one device, which actively pumps fresh blood through your knee joint, flushes out inflammatory compounds, and delivers healing oxygen and nutrients exactly where you need it. It's the combination of these two therapies working together that makes it so much more effective than anything you've tried before.
6. What if it doesn't work for me?
That's exactly why we offer our 60-Day Money-Back Guarantee. We want you to try FlexKnee Relief™ completely risk-free in your own home, on your own knees, in your own daily life. Use it for a full 60 days—if your knees aren't feeling noticeably better, if you're not moving easier and enjoying more of life, simply return it for a complete refund. No hoops to jump through, no restocking fees, no questions asked. You have absolutely nothing to lose except the pain that's been holding you back. We're that confident it will work for you, just like it has for over 50,000 others.
All OrthaPür™ orders are processed within 24–48 hours and delivered in 5–7 business days across the U.S., with tracking included so you can follow your package every step of the way.
Each order ships in a secure, branded poly mailer to ensure your insoles arrive in perfect condition.
We also back every purchase with a 60-day money-back guarantee—try OrthaPür™ risk-free, and if you’re not completely satisfied, simply contact us for an easy return and full refund.
As seen in
Your Doctor Told You to "Live With It." Here's Why That's Dead Wrong.
Chronic knee pain isn't a life sentence, it's a circulation problem that nobody's fixing. While you're masking symptoms with pills and braces, your joints are starving for blood flow. Without it, inflammation festers. Stiffness deepens. And every day, the damage compounds. There's a better way.
The Dirty Truth About Why Nothing's Worked So Far
Pain pills numb the ache but leave the root cause untouched. Braces might stabilize your knee, but they can't heal inflamed tissue or pump fresh oxygen where you need it most. Physical therapy works if you have the time, money, and willpower to keep showing up. Most people don't. That's why 50,000+ frustrated knee pain sufferers have turned to a solution doctors rarely mention.

Born from Desperation: A Physical Therapist's Mission to Save Her Father
Sarah Chen spent 20 years helping patients recover. But when her own father faced knee replacement surgery at 68, she couldn't accept it. She reverse-engineered the recovery tech used by NBA trainers and Olympic athletes into something anyone could afford. Her father canceled his surgery six weeks later. Now thousands are avoiding the operating table—using nothing but 15 minutes a day in their living room.

"Not gonna lie, I thought this was gonna be another waste of money. I've bought so many braces and heating pads that did NOTHING. But my daughter convinced me to try it. I use it every night while watching Jeopardy and my knees actually feel better in the morning. Like, noticeably better. The stiffness is almost gone. Wish I'd found this years ago tbh 🙏"
"Grandma of 4 here and knee pain was stopping me from getting on the floor with my babies. Started using FlexKnee Relief 3 weeks ago and yesterday I sat cross-legged playing blocks for 45 minutes. When I stood up WITHOUT PAIN I literally started crying. My daughter asked what was wrong and I said 'nothing's wrong everything's finally RIGHT.' Best investment I've made all year đź’™"

Frequently Asked Questions
Find answers to common questions about our products, shipping, returns, and more.
If you have a pacemaker, defibrillator, or any other implanted electrical device, please consult with your healthcare provider before using FlexKnee Relief™. While the device uses gentle heat and air compression (not electrical stimulation to your body), it's always best to get clearance from your doctor when you have any implanted medical devices. The same applies if you're pregnant, have circulation disorders, or are currently undergoing treatment for any serious medical condition. Your safety is our priority, and we want to ensure this device is appropriate for your specific situation.
FlexKnee Relief™ provides approximately 3-5 full therapy sessions (15-30 minutes each) on a single charge, depending on your heat and massage intensity settings. Higher settings will use more power, while lower settings extend battery life. The device charges fully in about 2-3 hours using the included USB cable, and you can plug it into any standard USB port, wall adapter, or power bank. Many users charge it overnight and use it 1-2 times daily without any issues. The rechargeable battery is designed to last for years of regular use.
FlexKnee Relief™ may be eligible for reimbursement through your Health Savings Account (HSA) or Flexible Spending Account (FSA), as it's a therapeutic medical device designed for pain relief and recovery. We recommend checking with your HSA/FSA administrator, as policies vary by provider. While we don't bill insurance directly, some customers have successfully submitted receipts for reimbursement. We provide detailed receipts with product descriptions that you can use when filing for reimbursement. As always, consult with your benefits administrator to understand your specific coverage.
FlexKnee Relief™ is designed as a single-knee device, meaning you'll use it on one knee at a time during each 15-30 minute session. Many users with bilateral knee pain (pain in both knees) treat one knee in the morning and the other in the evening, or do back-to-back sessions. If you need to treat both knees regularly and want the convenience of simultaneous therapy, we offer a bundle discount where you can purchase two devices at a reduced price. This is also popular with couples who both experience knee pain—they can each have their own device.
We stand behind FlexKnee Relief™ with a 60-Day Money-Back Guarantee. If you're not completely satisfied with your results within 60 days of purchase, simply contact our customer service team to initiate a return. We'll provide you with a prepaid return label (for US customers), and once we receive the device back, we'll issue a full refund—no questions asked, no restocking fees, no hassle. We want you to try this risk-free because we're confident it will make a real difference in your life. Your satisfaction is 100% guaranteed.
FlexKnee Relief™ uses similar therapeutic principles to what physical therapists employ—targeted heat therapy and compression to improve circulation and reduce inflammation. The key difference is convenience and cost. Physical therapy sessions typically cost $75-$150 each, require appointments, travel time, and multiple visits per week. With FlexKnee Relief™, you get unlimited therapy sessions from the comfort of your home for a one-time investment. Many of our customers use it as a complement to physical therapy (speeding up their recovery) or as an ongoing maintenance tool after PT ends. While it doesn't replace hands-on manual therapy or supervised exercises, it provides consistent, professional-grade thermal compression therapy whenever you need it.
FlexKnee Relief™ comes with two layers of protection. First, you have our 60-Day Money-Back Guarantee—if you don't love it, return it for a full refund within 60 days of purchase. Second, the device is covered by a 1-Year Manufacturer's Warranty against defects in materials and workmanship. If anything goes wrong with the device due to manufacturing issues within the first year, we'll replace it at no charge. This doesn't cover damage from misuse or accidents, but it does give you peace of mind that you're investing in a quality product built to last. Our customer service team is always here to help if you experience any issues.
"I rarely write reviews but this thing deserves one. I've had knee pain for 6+ years and tried EVERYTHING. My doctor wanted to do surgery. I got FlexKnee Relief 5 weeks ago and honestly... I can't believe the difference. I'm walking my dog again without limping. No more popping ibuprofen like candy. Feels like I got 10 years back."
