Last Monday Kip started acting stiff on his newly repaired right knee. We thought we had just over-exerted him on Sunday evening's exercise walk, so we let him take it easy for a few days.
By Wednesday he was not putting any weight on the leg at all.
We took him back to the specialist on Thursday morning who sedated him to do x-rays. The x-rays showed that his body was rejecting the metal plate and screws that were put in place during his TPLO surgery in January. The screws were "backing out" and had created space between the metal plate and his leg bone where an infection was growing. Luckily the hardware is only there to stabilize the bones until they heal from the original surgery, and the x-rays confirmed that the bones are healed, so they were able to go in and remove the plate and screws.
I mean, really. Could anything else possibly go wrong with this dog?! [Don't answer that.]
They told us that removing the hardware is much less invasive than inserting it, so it shouldn't be as traumatic.
By Friday he was already walking on the leg again. Turns out that not having an infected metal plate in your leg makes it feel better.
Hopefully we are (finally, for real this time) on the road to recovery.
