摘要
The objective of this retrospective review of 466 patients was to document changes in limb length, leg length discrepancy (LLD), height, weight, and body mass index (BMI) 1 year after TKA and the patterns of height, weight, and BMI during 5 years. To determine change patterns over 5 years, the data of 291 patients were analyzed and compared with those of age and gender-matched normal subjects. Limb length, height, and weight increased, BMI remained unchanged, and LLD decreased 1 year after TKA. The bilateral group had a greater height increase and lower rate of LLD. Preoperative mechanical tibiofemoral angle was related to limb length increase, and patients with a smaller preoperative BMI showed more weight gain. During the 5 years, weight and BMI at I year were maintained, but height diminished, while the healthy population showed a decreasing trend in weight. (C) 2013 Elsevier Inc. All rights reserved.
