My Mom's little girl Izzie was limping alot so they took her to the Specialist in AZ and he confirmed LP - he said Grade III
After surgery, he told my parents that she had already had arthritis set in
They are giving her Cosiquin daily too to help her with that arthritis - she doesn't limp anymore, but my Dad swears she sometimes walks funny ~ who knows....Sometimes we wind up stairs so much we think we see odd things
