How many degrees should you be able to bend your knee?

How many degrees should you be able to bend your knee?

A fully bent knee will max out at about a full range of motion of 135° degrees of flexion. As a general rule, a knee flexion of about 125° will allow you to carry out most normal activities. For daily living, a minimum flexion of around 105°-110° is required.

What degree should your knee bend after knee replacement?

Within 7 to 10 days after your knee replacement, you should be able to get your knee entirely straight/full extension (Fig. 1) (no space between the back of your knee and the table) and you should be able to bend/flex your knee to at least 90 degrees (Fig. 2). 90 degrees is the same thing as a right angle.

What’s the normal range of motion for a bent knee?

A fully bent knee will max out at about (full range of motion) at approximately 135 degrees. As a general rule, having knee flexion, or a knee bend, of 125 degrees will allow you to carry out most normal activities. According to my literature review ( study 1 and 2 ), the range of flexion required to do daily activities is as follows:

Is there a maximum bend after knee replacement?

There is always the risk of more surgery or lifelong joint problems so take preparation and recovery seriously. Be optimistic and be prepared to work hard during recovery. Be patient, your maximum knee bend after surgery will return, and may even improve.

What happens when you can’t bend your knee?

Besides pain and difficulty running / walking, this is often the most alarming change for people. To go from having ~120 degrees knee flexion (roughly heel to butt) to only ~90 degrees constitutes a very large percentage change in ability. While one often loses some knee extension (straightening) too, they may only lose 5-10 degrees.

What should your knee movement be after a knee replacement?

Normal motion after knee replacement is defined as the ability to get within 5 degrees of a straight knee and the ability to bend the knee back to 90 degrees. Most knee replacements have movement ranging from 0 degrees to 110 degrees or more.
