Knee Replacement Forum

I current have a medial partial knee replacement in my left knee and a lateral partial knee replacement in my right leg. The medial side of my right knee is becoming painful and I have recently consulted with the orthopedic surgeon that has been responsible for the past two surgeries described. He has suggested a medial partial be place in the right knee alongside the existing lateral partial in the right knee (two partials in one knee).  

I have pursued a second professional option which strongly opposed two partials in one knee and stated I should only consider a total knee replacement as my next step. He further stated that partial knee surgeries make it much more difficult to perform a total knee replacement because the end of the bones are now altered making conventional locating and fixturing points are nonfunctional.

I’m unable to find any information on two partials in one knee and I realize this is an unconventional surgery but biomechanically, invasively and general recovery seems to me to be advantaged. The original surgeon has done a fine job by me and did tell me this was an unconventional surgical technique. He stated he a successful performed this particular surgery on 25 patients with positive results. 

All opinions, statements and / or recommendations would be appreciated.
