The scruffy, out-of-control hairdo on this 10-pound female pooch was perhaps the first thing you would have noticed. The second thing you would likely have noticed is that she walked strangely. Her left hind leg didn’t do much. It mostly just dangled.
Veterinarians were alerted to her unusual gait and she was examined. Her leg was palpated and manipulated in various ways to evaluate whether there were broken bones, disrupted ligaments, pain, or nerve damage.
It was quickly determined that the issue was with her knee. Small dogs tend to have patellas (kneecaps) that luxate, known as MPL for Medial Patellar Luxation, which means that the patellas move out of their normal place and cause the dog to have an awkward and possibly uncomfortable gait. MPLs are graded on a scale of 1 to 4 with 4 being the most severe.
This dog’s leg was very strange. While the patella was indeed severely luxated – a grade 4 – there was also another component. Her leg felt very flaccid. Dr. Ostermann performed a drawer test on the dog and determined that she had ruptured one of her cruciate ligaments in her knee (analogous to an ACL tear in humans).
With such a severely affected leg, there was a question as to whether the leg would even be worth saving. To answer that question, the veterinarians at the San Jose Animal Care Center (SJACC) contacted specialty practice veterinarians at SAGE Centers and asked for their recommendation.
