Want to get some input please! Who has gone through 2 TPLO's on the same dog, how were the results and healing time? Worried my 8yr old female may have finally hurt her other knee after 7yrs from the first repair, so upset. She has also bad arthritis in the hock on her leg that had the TPLO before. We manage with lots of therapy and drugs when needed. Any input is appreciated, thank you!
