It is very important to do everything that your doctor and physical therapist tell you to do including your exercises!  Using both a Knee CPM and doing your recommended exercises will enhance your recovery while also reducing your pain and swelling.

Many doctors recommend using your Knee CPM machine at night to avoid waking up with a stiff, immobile knee in the morning. Usually, you can set your machine to 30 or 40 degrees of motion, lower the speed and still have a very restful night with less pain and swelling.  Use your knee CPM machine during the day at the end range of motion for flexion/extension levels and increase the speed. You never want to feel pain with the Knee CPM machine. If you do, decrease the range of motion until you no longer feel the pain. Your goal is to feel a light stretch at the end range of motion points. This will help reduce pain and swelling while increasing your range of motion.


In the event we are out of the Spectra model, we will substitute with another anatomical knee CPM like the Chattanooga K1 or KLC Flexmate K500.


We Accept Medicare for Total Knee Replacements!

    Superb customer service and helpful machines post-op

    Posted by Unknown on 11th Sep 2019

    I underwent bilateral hip arthroscopy in 2019 and I rented two knee CPM machines from Medcom. Post-op the knee CPM machines are helping me rehab my hips while I sleep. The knee CPM machines also help me sleep because they reduce my back discomfort, while sleeping on my back, by gently and subtly oscillating between extending and flexing my lumbar discs. The knee CPM machines have the additional benefit of reducing the risk of blood clots post-op, whereas iflatable pneumatic compression devices reduce the risk of blood clots but do not give some of the other benefits of the knee CPM machines, which are jump-starting rehabilitation and reducing the risk of scar tissue formation in soft tissue perforated to reach the hip joint intra-operatively. The knee CPM machines post-op make sense in light of the physician assistant that instructed my caretaker to move my legs and hips, during some the post-op period, almost exactly as the knee CPM machines do. My caretaker no longer needed to do this for me as I would get over seven hours of essentially the same movement every day, via the knee CPM machines. The surgeon instructed me to avoid hip external rotation and hip extension for several weeks post-op. This is easy to follow at least when I sleep because the knee CPM machines keep my hip from externally rotating (as long as I properly orient the knee CPM machine and pad the lower leg support with some rolled up t-shirts to better secure my lower leg), and I can precisely dial in the end range-of-motion of the CPM machines to stay well clear of hip extension. The rehab instructions indicate that I should use an upright stationary bicycle everyday, as early as the night of surgery, and for several weeks thereafter, and while a CPM machine causes passive hip and knee movement, clearly the rehab protocol encourages some hip and knee movement early in the rehab period. I'd like to share some information that helped me when renting knee CPM machines. I'm glad that I rented the CPM a few days before surgery because this gave me a chance to experiment with adjusting, and learning to use, the CPM machines while I was more mobile, and in less pain, than I would be that first night post-op. If you are generally not very flexible or if you have gotten cramps then I suggest stretching your calves before using the CPM machines. If you want to better secure your legs, make available some t-shirts (or sweatshirts or sweatpants) that you don't mind rolling up to stuff between your leg and the included fabric support layer, and that you don't mind possibly rolling about any surface that produces discomfort while you use the CPM machine. If you will use two knee CPM machines simultaneously, then have a stiff and preferable thin cushion available to place between the knee CPM machines. This will prevent the knee CPM machines from banging into each other. The knee CPM machines arrived impeccably clean, as did the padding on which I rest my legs. I found that the two gentlemen that helped me in the rental process were knowledgeable, attentive listeners, professional, and extremely polite. They patiently answered all questions clearly and made the entire process quite easy.

    Glad my hip surgeon prescribed this post surgery!

    Posted by Sue in Georgia on 20th Aug 2017

    This Spectra CPM was easy to use and helped me so much after my hip surgery! Being able to set the range of motion degrees and increase them incrementally as I could tolerate benefited me in my recovery. MedCom made deliveries very easy.

    The machine worked great. I rented it for a friend. Four weeks after surgery her knee was stiff and therapy was not helping. The machine was amazing. She got almost full motion in the three weeks she had the machine.
