Everex is a healthcare company founded in 2019 by Dr.Yoon, an orthopedic surgeon who specializes in knee joints.

Our vision is to provide easy, inexpensive, and effective ways to perform knee joint rehabilitation exercises-which are currently very difficult to do at home.

A message from the CEO

The knee joint has a unique structure because it relies heavily on the functions of its surrounding ligaments and muscles in order to stabilize its inherently unstable skeletal structure.

Due to these characteristics, the incidence rate of sports injury to the knee is high, and the knee joint has the highest incidence rate of degenerative arthritis.

Encouragingly, however, recent studies have found the following: strengthening the muscles around the knee joint reduced symptoms of degenerative arthritis, accelerated return to daily life after injury, and reduced symptoms of anterior knee pain syndrome, which are very common among young women.
Working as a full-time orthopedic surgeon for 7 years, I have witnessed firsthand that pain can be relieved by strengthening the muscles around the knee joint, but at the same time, I realized that simply educating the patients to perform these exercises results in very low compliance.
Therefore, we developed the KneeEx solution. The solution comes from the idea that patients should be able to rehabilitate at home without having to worry about time and cost. Also by making rehabilitation a fun experience through KneeEx, there is no doubt that patients’ will have an increased adherence to the rehabilitation treatment.
We hope that KneeEx will help many people that are in need of knee joint rehabilitation.

KneeEx solution



KneeEx is an exercise solution specialized for knee joints. 

it consists of exercise equipment that can perform customized exercised according to individual knee conditions, and a dedicated mobile application that can control and check data

KneeEx - the main Body

The user can adjust the device's resistance level according to the knee condition and desired exercise intensity (the load can be set between 0-10Kg). If the rehabilitation condition requires restrictions on the range of motion of the knee, the user can limit the equipment's range of motion. Also, there are a control monitor and Bluetooth (to connect to the KneeEx mobile app) on the main body that allows the user to control the device and check the exercise data.

KneeWalk - EMS part

The EMS part of the device is a functional electronic stimulation device that increases the exercise efficiency on specific muscles. With EMS, it is possible to maximize the efficiency of muscle movement by applying electrical stimulation to the quadriceps. The EMS is also used to address the imbalance between muscles around the knee joint. A total of 11 muscle stimulation programs are provided for the user-selected based on his/her needs.

Mobile application

The mobiile app recommends optimal exercise programs customized to the user's characteristics  - such
