What is Range of Motion?
Range of Motion (ROM) is a term that physical therapists and other health professionals use to describe how much someone can move one of their joints. This amount of movement can change based on how the tissues (muscles, ligaments, cartilage, fluid) that surround your joint are behaving.
When you ride a bicycle, go for a walk, or kick a soccer ball, there are two main movements your knee performs: you can bend your knee (known as flexion) and straighten your knee (known as extension).
Physical Therapists will often measure your range of motion in degrees, and may compare it to the average amount of movement that most healthy individuals have. Having an optimal range of motion gives your joint a greater chance to be a strong performer in your daily activities.
Why is Range of Motion Important Following My Knee Replacement?
Swelling, weakness, pain, and fear of movement are all common following your knee surgery and may all contribute to less motion in your knee. Your knee will likely feel stiff and be unable to move as much as your uninjured knee. Throughout your recovery, one of your main goals will be to regain as much of your flexion and extension range of motion as possible.
The amount of movement in your knee during your recovery will determine the types of activities you are able to do after surgery! While full knee flexion or bending is not required for all activities, a research study shows that a minimum of 110 degrees of active knee flexion (bending your knee without the help of your therapist) is ideal for walking, climbing stairs, and getting up from sitting to standing.
