Dr. said my wife has a knee contusion from her fall 2 months ago and she still can not walk with out a walker?

Her leg feels wobble when she tries to stand on it. She is going to physical theropy 2 times a week. Is this normal not being able to walk after a knee contusion. She is 56yrs old 5' 7" and only weights 125 and was very active before the fall if that helps any.Dr. said my wife has a knee contusion from her fall 2 months ago and she still can not walk with out a walker?
Nope, not normal for a simple contusion (which basically means bruise). Does she have arthritis or osteoporosis? Did the doc have an MRI done? If not, she probably needs to have one. If I were you, I'd request a referal to an orthopaedic specialist. Again, 2 months on a walker after a contusion is not normal! Good luck!
