Do I need a CPM device after knee surgery?
After knee surgery, for example after a knee replacement or cruciate ligament surgery, early mobilization of the joint is crucial. Movement helps prevent adhesions, reduce swelling, and support wound healing. This is exactly where a motorized CPM device after knee surgery comes into play.
A motorized CPM device, also called a CPM device (Continuous passive motion) and often known in Switzerland by the term "Kinetec," moves your knee joint passively and continuously. This means that your muscles do not have to work actively. The device performs the movement gently and in a controlled manner.
This is a major advantage, especially in the first days and weeks after surgery. Pain and swelling often make active exercises difficult. The CPM device still enables regular and continuous joint movement.
What studies show about CPM therapy
Many scientific studies have examined how CPM therapy affects recovery after knee surgery. Overall, the results show a clear picture: early and regular movement of the knee joint can support rehabilitation and improve mobility more quickly.
Patients benefit particularly from the fact that the joint is moved early and regularly, even when active exercises are still difficult. This can reduce the risk of adhesions in the joint and keep the knee mobile.
Large scientific reviews also show that CPM therapy can improve early mobility of the knee joint and, in many cases, helps avoid additional surgeries.
Many specialists therefore recommend starting CPM therapy as early as possible after surgery and using it regularly. It is particularly effective in combination with physiotherapy.
The passive movement provided by the device complements the active exercises from physiotherapy and thus supports the entire healing process.

ARTROMOT and Kinetec: devices in use
In Switzerland, devices from the brands ARTROMOT and Kinetec are frequently used. One common model is, for example, the ARTROMOT K1 Classic, which is also used by WINTER Medizintechnik AG.
The outstanding quality and reliability make the ARTROMOT K1 one of the best rental devices for the knee joint.
These CPM devices allow precise adjustment of the knee joint's range of motion.
Typical features of these devices:
Motorized and continuous joint movement (CPM)
Individual adjustment of flexion and extension angles from approximately minus 10 to 120 degrees
Adjustment of movement speed
Option for short pauses at the end points of the movement
Easy operation at home
Quiet motor for everyday use
The ARTROMOT K1 Classic is designed to be especially user-friendly and is very easy to operate compared with many other devices.
Correct and individually tailored setup by specialist staff is very important. Only when the flexion and extension angles are precisely matched to your body measurements and the healing process can CPM therapy achieve its full effect.
CPM therapy and physiotherapy: how the two work together
The CPM device does not replace physiotherapy. It complements it.
During physiotherapy, you actively train strength, coordination, and mobility. The CPM device also moves the joint passively, including during the times between therapy sessions.
Many specialists recommend a combination of both methods:
CPM therapy several times a day, usually 3 to 6 times for 30 to 60 minutes each, as early as possible after surgery
Regular physiotherapy for active strengthening and improvement of mobility
Regular medical checkups of the healing process
