Wish I had experience u could benefit from but this is a perfect application for AI. With enough data, a well written piece of diagnostic software could identify those characteristics delineating which patients benefit and those that are unlikely to benefit. I would not be surprised to find the same characteristics in knee and hip patients. One would hope that Mayo or Cleveland is accumulating said data so patients rely upon something more than hope and their doctor's best guess.

Ask your doc for any available study results. Regards.
