Eshnazarov, MD; Jong-Keun Seon, MD, PhD, Associate Professor; Eun-Kyoo Song, MD, PhD, Professor Chonnam National University Hwasun Hospital, 322 Seoyang-ro Hwasun-eup. <...> The purpose of this prospective study was to compare radiological outcomes after total knee arthroplasty (TKA) with or without patellar resurfacing in patients with grade IV osteoarthritis on patellofemoral joint. <...> Material and methods. 123 cases with Kellgren–Lawrence grade IV osteoarthritis on patellofemoral joint were enrolled for this study. <...> At the operating room, they were randomly assigned to undergo patella resurfacing (62 cases) or patella retention (61 cases). <...> Preoperative and postoperative radiological outcomes (mechanical femorotibial angle, patellar tilt and congruence angles) were evaluated and compared between two groups. <...> Preoperative radiological measures shows not significant difference between patellar tilt (P = 0.13), mechanical femorotibial angles (P = 0.62) and congruence angle (P = 0.37). <...> Despite the difference performed methods of surgery, postoperative radiological assessment outcomes between two groups were almost identical Patellar tilt (P = 0,47), mechanical femorotibial angles (P = 0.34) and congruence angle (P >0.05). <...> Obtained almost the same satisfactory radiological outcomes after patella resurfacing and retention groups after total knee replacement allows us to conclude that, primary TKA without patella resurfacing is a good treatment option in patients with high grade osteoarthritis of the patellofemoral joint. <...> Vestnik Rentgenologii i Radiologii (Journal of Roentgenology and Radiology, Russian journal). 2016; 97 (1): 28–32 (in Russ.). <...> DOI: 10.20862/0042-4676-2016-971-28-32 For correspondence: Kamolhuja E. <...>
