- W1509207788 abstract "Objective: Since patellar replacement in total knee prostheses is a topic of controversy, we proposed to quantify the morbidity of patellar substitution. Experimental design: A retrospective study of patellar component failures (reoperations for patellar problems alone) in a series in which patellar replacement was performed systematically. Materials and methods: Three hundred thirty-five arthroplasties of different designs were implanted by the same surgeon or under his direct supervision. The mean follow-up was 7.3 years. Results: There were 7 failures of the patellar component (2.08%): 2 subdislocations, 3 patellar fractures, 1 implant dissociation, and 1 peripatellar fibrosis. The surgical interventions performed were proximal realignment of the subdislocation, patellectomy for fractures and implant dissociation, and removal of fibrous tissue in the case of peripatellar fibrosis. The failure rate did not show any statistically significant relation with the prosthesis model (Chi square; p = 0.15) or underlying diagnosis (Chi square; p = 0.64). Conclusions: Considering the low complication rate and the clinical and biomechanical advantages of the procedure, systematic patellar replacement using a meticulous technique in total knee prostheses should not be overlooked." @default.
