We had one knee done this year and it was $1900. The surgeon is well known and board certified, and does many of these types of surgies. It included one night hosp stay, follow up check-ups and any pre-op tests. The initial consult was an additional $120.00 (I think). Good luck with your baby. Ours was done pretty much as soon as it manifested itself and it was a grade 3. The surgeon says that Hot Rod should not develop arthritis in that knee.
