I've had both hernia repair and hip replacement and I'm VERY glad I didn't watch surgery videos before either procedure. Some things are best left to the imagination, and both were generally beyond my imagination thankfully. In each case I was given very good drugs and appreciated it!
And as others have said, sleeping in a recliner does make things quite a bit easier - for hernia and especially hip replacement. The "getting into" part of a bed isn't too uncomfortable but the "getting out" part can be very memorable - and it's a memory that doesn't fade quickly.
