🐾 “My dog needs a TPLO after tearing their cruciate ligament”… but what does that actually mean?
If your dog has suddenly started limping on a back leg, there’s a good chance their cranial cruciate ligament may be the culprit.
This ligament is exactly the same as the ACL in humans, helping to stabilise the knee joint. But in dogs, it often doesn’t tear from one dramatic injury — instead, it gradually weakens over time until it finally gives way.
The result?
Pain, limping, difficulty getting up, and if left untreated, arthritis in the joint.
That’s where TPLO surgery comes in.
Now, TPLO sounds complicated (and honestly, it is!), but the goal is actually pretty simple:
👉 to make the knee stable again so your dog can move comfortably.
During the surgery:
🐶 The top of the shin bone is carefully cut
🐶 The bone is rotated to change the angle of the knee
🐶 A metal plate is placed to hold everything securely in position
This changes the mechanics of the knee so the damaged ligament is no longer needed for stability.
It’s amazing to think that by changing the angle of the bone, we can help dogs get back to doing what they do best — running, playing, and enjoying life pain free 💙
Because TPLO is a specialised orthopaedic surgery, choosing an experienced surgeon is really important.
At SHVC, we’re fortunate to be able to offer specialist orthopaedic surgery in-house, as well as referral to a specialist hospital in Sydney, so together we can create the best plan for you and your pet.
Our beautiful patient here, Scout, is currently recovering from her TPLO procedure and as you can see, she is walking comfortably and is her happy and bouncy self again!
🐾 If your dog is limping or you have questions about cruciate injuries, we’re always here to help.
