Does acl reconstruction cause pain in hamstring?

No: The repair itself does not cause hamstring pain. The pain is secondary to either weak hams or from hamstring spasm from inflammation in the knee joint.

NO: After acl reconstruction, pain in hamstrings is not common may not be related to acl repair, see your surgeon , you may have a unrelated problem , like vascular insufficiency etc , will do the tests and find out the cause of your hamstring muscle pain.

Indirectly: Most likely you still have quad weakness after your reconstruction. You will still limp with your knee hyperextended when you walk longer periods. You'll have difficulty going down stairs, and you'll have burning down the leg to the calf in the evenings. First, force yourself to stop limping. Second, work diligently on your quads (remember your exercises?) you'll start improving within days!
