Abstract
48 knees that underwent of TKA with OA diagnosis as an RCT with prospective plan divided double blind in two groups of patelloplasty & boney medialization And sham group with regular patelloplasty. We followed them for a year and 3 times clinical and x-Ray checking, immediately after surgery and in 3 months and 12 months post surgery. In term of clinical finding they looked the same but in radiography, patellar medialization had superior manifestations. Although is seems that is too soon to talk about mid or long term results of this procedure, but to be sure about positioning of patella in x-Ray looks better.
