Patellarluxation is a complex disease and all cases are unik but 90% I handle easy Checking patellar grow. Most cases dont need deepening but if they do I prefer wedge osteotomy in the realy small dogs less than 5 kg and blockresektion in larger dogs.

When the creast breaks I have to fix it with pin and tension band wire Always fabella to patellasutur that holds the patella in the right position during healing CCl rupture in small dogs and cats I still do one monofil nylonsuture around both fabellas and thrue a hole in the tibial creast 1/27/2017 NOVOS FORUM 28 JANUARY 2017 7
