That is what I have always believed (it might even have been you that told me!!)

During TPLO and TTA surgery, the osteotomy often goes right through this feature and on the few occasions I have looked, there has been a well circumscribed area of something looking and feeling like hyaline cartilage.

Let us know what the repeat biochemistry says. Alk phos has a bone isoenzyme.

Thank you

A normal, if inconsistent, finding. Sometimes can look so perfect it resembles a drill tunnel for a novel CCL procedure! Must represent a bony void and is at the convergence of the ossification centres of the proximal tibia. The changes in the stifle are consistent with the clinical diagnosis of CCL failure. Popliteal node visible and normal size.

I'd run that biochemistry again fasted before reading too much into it. If it's still not right then fair enough may be worth thinking about some follow-up testing of some sort.

I don't see anything that makes me think myeloma here.

Put into google images : "cruciate dog xray" and you get a reassuring number of pictures looking similar to this I think.

Always hardest with you own pets. Most recently I sedated my nervous rescue cat with medetomidine/butorphanol SC using an insulin needle at home (almost getting scrabbed in the process) before I was brave enough to microchip. I don't remember ever having such difficulty and taking such an approach with anyone else's cat. Oh, and I was so flustered I forgot to vaccinate him at the same time and still haven't gotten up the courage to tackle that - highly irrational.

The owner is me! I wondered the same but tend to see the worst when my pets are concerned. Myeloma and doing electrophoresis were also thoughts.

my screen's not the best (face-saving comment in case I'm totally wrong!), but I just see a cruciate here.

The radiolucnet hole punch on lateral in top of tibia cranially is a common finding I think - don't ask me eactly what, but somethiong to do with 3 separate ossification centres meeting there and a little bit in middle staying bit more cartilagenous perhaps?

Perhaps wait for another opinion before telling this to owner though in case I'm way off!

PS - I would repeat the biochemistry before thinking about it more - something smells fishy about those results, perhaps the Albumin of 39?
