Knee Surg Sports Traumatol Arthrosc. 2014 Mar;22(3):509-16. doi: 10.1007/s00167-012-2281-2. Epub 2012 Nov 3.69 patients undergoing primary TKA for unilateral knee osteoarthritis were randomized to undergo the procedure using either mobile or fixed bearings, with the purpose of comparing incidence of anterior knee pain between groups at a mean of 7.9 years post-surgery.
