LP is Luxating Patella, when the knee cap keeps sliding off and on. When it slides off and won't go back on, then it's a grade 4 and surgery is needed. My Zada had surgery when she wasn't limping and I found out by the orthopedic Doctor who operated on her for a torn ligament, that the first surgery wasn't done right. The groove the knee cap sits on wasn't made deeper, so the knee cap was also slipping again. He said if they are not limping, then don't fix it. My Azrael has grade 3 but never limps. She's had it ever since I got her at 5 months old. Most go thru their entire life without needing surgery. |
