I am not sure how the incline would impact on your knees other than the load to straighten the leg which is borne by the quadriceps muscle. Since those muscles wrap around and stabilize the knee through the patella tendon there may develop some muscle soreness. Nothing about the incline should have any impact on the underlying ligaments which hold the joint together. Since the belt pulls the leg to the rear the hamstring which curls the leg has a very limited involvement, straightening the leg involves the quads and the glutes. Increasing the incline should have not increase the impact when you place the foot down on the belt. It is analogous walking uphill which impacts the quadriceps almost exclusively.

I recommend investigating and learning about learning about kinesology which explains how which muscle does what and when. With this knowledge you can determine what is happening when you do a certain movement.

I have knee problems and my Orthopedic surgeon told me to NOT walk or run with an incline on the treadmill. I will put the incline on a .5 but that is it.

68,

I would vary the incline from time to time allowing for different muscles to be targeted. Incline is great for hamstring development but with exercise the goal in balance between opposing muscle groups, therefore, dropping it to 1-2% for a few sessions.

I wish you well!

While using the incline does involve some bending of the knee, using the incline is a great way of increasing the intensity of your workout, without increase the speed and associated impact.

Hi,

I usually walk on the treadmill on a 10% incline, between 30 - 60 minutes, is this bad for the knees?
