Patellar facet ratio affects knee pain, stair climbing and stair descent after TKA without patellar resurfacing

ConclusionThe findings of this study partly confirm the hypotheses that pain and functional impairments after TKA without patellar resurfacing are associated with patellar shape. No association was revealed between postoperative patellar orientation and function nor pain. Quantitative consideration of patellar congruency could therefore prevent pain and improve function after TKA without patellar resurfacing.Level of evidenceRetrospective study, Level III.
