If the doctor recommends to have the meniscus arthroscopy repaired make it clear to the doctor if the meniscus is not repairable do not remove it unless the doctor has consent first.
If they removed the meniscus now he will be bone on bone and that's where all hell breaks loose. You think he's in pain now, ha ha I can tell you from personal experience the pain from a torn meniscus is ice cream compared to being bone on bone.
There are alternative treatment now that I wish were around when I had my knee replacement.
