Interesting Case
Luxating Patellas -

“Murphy” Goodrich is a 2 ˝ year old, male, neutered, Pug. Murphy presented for limping on both hind limbs with the left hind limb more affected than the right.

Upon a thorough orthopedic exam Murphy was found to have problems with both his kneecaps. Murphy was diagnosed with what we call medial luxating patellas.

This is a condition in which the kneecap (patella) moves out of its normal position and luxates to the inside (medial side) of the leg. Luxating patellas are more common in smaller breed dogs, but can occur in larger breed dogs as well. Any age dog can be affected. The kneecap can be displaced to the outside or the inside of the leg, however, the inside is much more common. There are several different anatomical abnormalities of the hind limb which contribute to this problem.

The diagnosis is based on physical exam findings. Medial patellar luxation may be treated conservatively or surgically depending on severity.

Both of Murphy’s hind limbs were affected and both were surgically repaired at the same time.

After surgery the prognosis is good for return to normal limb function.
