Many doctors recommend using your knee CPM at night to avoid waking up with a stiff immobile knee in the morning. Usually, you can set your machine to 40 or 50 degrees of flexion and still have a very restful night with less pain and swelling.

Use your CPM during the day at higher flexion levels to reduce pain and swelling while increasing your range of motion.

Remember: It is very important to do everything that your doctor and physical therapist tell you to do including your exercises.

Using a Knee CPM and doing your recommended exercises will help improve your recovery while also reducing your pain and swelling.
