BACKGROUND: Operative treatment of geriatric @entity174 is challenging and controversial. There are few studies focusing on the clinical features and operative outcomes of @entity174 in the elderly. Hence, this study aimed to investigate the clinical features and operative results of these @entity174 . METHODS: Thirty-three displaced @entity174 in @entity1 >65 years old (mean age: 72.1 years, range: 65-94 years) were treated operatively. We investigated the mechanisms of injury, @entity174 types according to the Schatzker classification, incidences of soft tissue injury, and @entity260 . Clinical and radiographic data were analyzed in 23 @entity1 at the last follow-up. The mean follow-up period was 4.0 years (range: 1-13 years). Twenty-one @entity1 were treated with open reduction and internal fixation and evaluated using the Rasmussen clinical and radiologic scores. Two @entity1 with advanced @entity571 were treated primarily with total knee arthroplasty and assessed using the Japanese Orthopaedic Association score for the @entity626 . RESULTS: Twenty-four @entity1 (72.7%) were injured by low-energy @entity130 such as a simple fall. Four @entity1 had @entity2054 and required fasciotomies. Rasmussen clinical and radiologic scores were satisfactory in 85.7% and 81.0% of @entity1 , respectively. Two @entity1 treated primarily with total knee arthroplasty showed no radiologic abnormality, and their Japanese Orthopaedic Association scores were both 70 points. CONCLUSIONS: @entity174 , although mostly due to low-energy @entity130 , were often accompanied with severe comminution and @entity2054 . Postoperative results of open reduction and internal fixation for this population were relatively good. Therefore, primary total knee arthroplasty should only be considered for well-selected @entity1 .
