How to Use


Nearly 15 percent of patients who undergo total knee arthroplasty (TKA, or total knee replacement) experience arthrofibrosis – a post-operative complication where excessive scar tissue formation leads to painful and/or restricted knee motion.1 It is impossible for these patients, and other patients with knee arthrofibrosis, to effectively stretch or passively rotate their own knee without assistance. That’s why they need a device that promotes range of motion and stretch in extension to reduce pain and gain function.


Quick Start User Guide


First, open the KneeMD by pressing down on the black buttons and rotate the handle up.


To lock the handles into place,
let go of the black buttons.


Place KneeMD next to your affected leg and set the pads to the proper length.


The black knee pads should sit above and below your affected knee. (Be careful to not place pads directly over incisions or the area of injury.)


Adjust the red ankle pad so that it can be placed directly behind your ankle.


Slowly place your leg into KneeMD.


Keep your arms straight in front you and gently pull the handle toward your chest until you feel the stretch.


Hold the stretch for
30 seconds and repeat.

Use for Various Stages of TKA, Rehabilitation, Knee Recovery and Regular Therapy in Virtually Any Setting

Patient Controlled Stretch

With KneeMD, patients can perform extension stretches while lying down, sitting up or even standing, to stretch the leg and joint in different ways.

Passive Rotation

KneeMD can be used to passively rotate the knee joint through its available range of motion, which is especially beneficial before and after stretching or after a long period of inactivity, such as sitting in an office chair.

Other Stretches

KneeMD can also be used for stretching in a therapy pool, doing hamstring stretches or even performing extension stretches while walking.

Use As A Supplemental Device

In addition to being used to correct range of motion or extension deficits, KneeMD can be used as a supplemental or transitional device from continuous passive motion (CPM) devices.

Amazingly Versatile



Endorsed by world-renowned orthopedic surgeon, Dr. Richard Steadman, founder of the Steadman Hawkins Clinic and Steadman Philippon Research Institute, KneeMD is a knee rehabilitation device which makes it easy for patients to take control of improvements in their range of motion after knee surgery or knee injuries that lead to knee extension deficits.
Using KneeMD, patients can simulate the range of motion and stretch exercises that physical therapists perform during rehabilitation on their own. Physical therapists report using KneeMD on 100% of patients who are recovering from total knee arthroplasty (TKA, or total knee replacement) and anterior cruciate ligament (ACL) surgery, as well as on other patients with knee extension deficits.




What People Are Saying

  • “Patients are allowed full control of the stretching and mobilizing, therefore, they can appropriately adjust the intensity allowing for them to decrease overall guarding.”
    Laurie Griffin, Physical Therapist, Howard Head Sports Medicine
  • It helps me tremendously. I use before every game before I warm up and start activity. Then use after game. It allows my knee to get that extra couple degrees and puts less stress on my leg. My trainers even pack it on all the road trips. I like how convenient it is as well. i know my knee wouldn't be as good as it is now with out it.
    Chris Coughlan, 2009 NL Rookie of the Year
  • “Of all the apparatuses that are presently available to facilitate knee extension, I feel that the (KneeMD) is far and away the best machine to facilitate extension in the clinic as well as in the home….  All of my patients who have (used it) would express the same feeling.”
    Brent Butler, Physical Therapist, Central Utah Clinic
  • “Great tool to give patients to use at home as part of a HEP (home exercise program).”
    Luke O’Brien, Head of Physical Therapy, Howard Head Sports Medicine
  • “KneeMD has helped greatly with my rehab, as I can work on extension for extended periods of time at home and with less pain than (other devices). The ability to control the tension allows me to push harder than when allowing PT’s to manipulate, because I can control the pain.”
    Christy H, Patient, knee surgery with range of motion deficit
  • “[KneeMD is the] most direct way to increase extension.”
    Ray K, Patient, knee surgery with range of motion deficit
