| 1 | Why total knees fail-A modern perspective review显示文摘Historically, the most common mechanism of total kneearthroplasty(TKA) failures included aseptic loosening, instability and malalignment. As polyethylene production improved, modes of failure from polyethylene wear and subsequent osteolysis became less prevalent. Newer longitudinal studies report that infection has become the primary acute cause of failure with loosening and instability remaining as the overall greatest reasons for revision. Clinical database and worldwide national registries confirm these reports. With an increasing amount of TKA operations performed in the United States, and with focus on value-based healthcare, it is imperative to understand why total knees fail. | Zachary C Lum Alvin K Shieh Lawrence D Dorr | 2018 | World Journal of Orthopedics2018，9，4： | 9 |
