Patella tilt post TKA

My colleague Dr gnanavel has just come out with a paper  that a patellar tilt of more than 10 degrees might be associated with poor out come in TKA when patella specific scores are used to predict the outcome. He suggested that it would  be advisable  to use patellar specific scores in all future studies investigating the ever controversial patella in TKA. So consider merchants or skyline view and melbourne scores to asses anterior knee pain which is ever present if you ask for it in 10 to 30 percent of individuals.
