What is cranial cruciate ligament (CCL) disease?
The cranial cruciate ligament stabilizes the knee, much like the ACL in people. In dogs it usually weakens over time and then tears, causing hind-limb lameness and pain. Surgery such as a TPLO stabilizes the knee, but the muscles around it weaken quickly while it heals, and arthritis can still develop over time.
Signs to watch for
- Limping or holding up a back leg
- Sitting with one leg kicked out to the side
- Trouble rising, jumping or using stairs
- Thinner muscle on the affected thigh
How rehab helps
- Controls pain and swelling in the first weeks after surgery
- Encourages early, correct use of the leg
- Rebuilds thigh muscle and restores knee motion
- Guides a safe return to full activity and helps protect the other knee
What to expect in rehab for TPLO & CCL surgery
Rehab usually begins within days of surgery with pain control, gentle range-of-motion work and short, controlled leash walks. Over the following weeks, exercises progress to build strength and balance as the bone heals, and your surgeon's recheck X-rays guide when more activity is safe. Most dogs work toward a gradual return to normal activity over several months. Because arthritis can still develop in the knee later in life, we can also help manage long-term joint comfort.
