You can safely use an electric knee massager for 15–30 minutes per session, once or twice a day. Most devices have an auto shut-off to prevent overuse. Avoid using it for longer than 30 minutes at a time, and if you have knee injuries or medical conditions, check with your doctor first.

An electric knee massager is generally safe, but using it too long or too often can sometimes cause skin irritation, redness, or mild discomfort. Some people may feel temporary soreness after the first few uses. If you have knee injuries, implants, or medical conditions, it’s best to check with a doctor before regular use to stay safe.

A knee massager works by combining vibration, air compression, and sometimes heat therapy to soothe sore muscles, improve blood circulation, and reduce stiffness or pain around the knee joint. Regular use can help with relaxation and support recovery after exercise.

Knee massagers are generally designed for adults, but they may not be suitable for children or older adults with certain health conditions. It’s always best to check with a doctor before use to ensure safety.
