Make My Knee Great Again T-Shirt

BEFORE stretching produces the best results.

Here's why: Scar tissue (fibrin) behaves differently at different temperatures. When tissue is cold, stretching creates micro-tears that trigger your body to produce MORE scar tissue. When tissue is warm, it becomes pliable and releases permanently.

Use Vozdic for 15-20 minutes before your PT exercises or stretching routine. The deep heat elevates tissue temperature so your stretches actually produce lasting gains instead of triggering the repair response.

Many users also apply it immediately after PT to flush swelling before it triggers overnight stiffness.

This is one of the most frustrating parts of knee recovery—and it has a biological explanation.

When you push hard during PT, your nervous system can interpret the aggressive movement as a threat. It responds by "splinting"—clamping the muscles around your knee to protect the joint. This happens automatically while you sleep, when your conscious mind can't override it.

Vozdic helps by calming the nervous system before and after stretching. The combination of heat, gentle vibration, and compression sends "safe" signals that reduce the protective response. Users consistently report that their morning flexion stays much closer to their night-before numbers.

Yes. Vozdic is non-invasive and uses gentle heat, vibration, and compression—the same therapeutic modalities recommended by physical therapists for post-surgical recovery.

Important timing note: Most surgeons recommend waiting until your incision is fully healed (typically 2-3 weeks post-op) before using any device on the surgical area. Always check with your surgeon or PT before starting.

Once cleared, many post-TKR users find Vozdic especially helpful for:

• Warming tissue before PT exercises
• Reducing swelling after sessions
• Managing the "tight band" sensation
• Preventing overnight regression

Heating pads only warm the surface. Vozdic delivers deep infrared heat that penetrates to the joint level where scar tissue actually lives.

Massage guns use aggressive percussion designed for large muscle groups. They're often too intense for the sensitive tissue around the knee and can actually trigger protective responses that increase stiffness.

Vozdic combines three modalities specifically calibrated for joint recovery:

• Deep infrared heat — elevates tissue temperature 3-4°C to soften fibrin
• Low-frequency vibration — sends calming signals to the nervous system
• Adjustable compression — supports the joint and helps flush swelling

The combination matters. Heat alone helps. Compression alone helps. But together, they address both the mechanical (tissue temperature) and neurological (protection response) factors that cause overnight regression.

Most users notice a difference in overnight retention within the first few sessions—specifically, they lose fewer degrees between evening and morning.

Typical timeline:

• Days 1-3: Knee feels looser after use; stretching meets less resistance
• Week 1: Morning flexion stays closer to night-before numbers
• Weeks 2-4: Gains begin stacking instead of resetting
• Weeks 4-8: Measurable progress toward flexion goals

Results depend on consistency. Users who apply Vozdic before every stretch session see faster progress than occasional users. The key is making tissue preparation part of your daily routine, not just an occasional add-on.

We can't make medical promises—that decision is between you and your surgeon.

What we can say: Many users have reported hitting their flexion goals and canceling scheduled MUA procedures after consistent Vozdic use. The mechanism makes sense—if you can break the cycle of overnight regression and actually stack your gains, you're more likely to hit the numbers your surgeon needs to see.

If you're approaching a potential MUA decision, Vozdic offers a low-risk option to try first. With our 90-day guarantee, you can test whether improved tissue preparation helps you hit your goals before committing to another procedure.

90 days, completely risk-free.

Use Vozdic for up to 90 days. If you don't see improvement in your overnight retention, your flexion progress, or your overall knee comfort—email us at support@vozdic.com for a full refund.

We offer this guarantee because the mechanism works. Warming tissue before stretching produces better results than stretching cold. Flushing swelling prevents the triggers that cause regression. These aren't theories—they're basic tissue physics that physical therapists have known for decades.

The only way to know if it works for YOUR knee is to try it. We've removed all the risk so you can find out.
