Since you indicated the weight used for seated VS lying, i’m willing to guess that the lying is with your home gym machine? 99% of the time those are trash (plate loaded leg extension/curl type of machine?), it may be the reason why it bothers your knees (support, pad, rotation point, strength curve really bad, etc etc). Do you have any issue with a “real” lying curl machine?
