研究目的: |
主要目标:测量并评估髌骨骨折术后12个月内髌腱长度的动态演变规律 。 次要目标:(1)量化髌腱短缩量与膝关节屈曲角度(ROM)损失的相关性 ;(2)评估短缩对Lysholm及Kujala功能评分的影响 ;(3)识别导致严重短缩的危险因素(如骨折AO分型、固定方式、制动时长等) 。 |
||||||||||||||||||||||
|
Objectives of Study: |
Primary Objective: To measure and evaluate the dynamic evolution of patellar tendon length within 12 months after internal fixation of patellar fractures. Secondary Objectives: (1) To quantify the correlation between the amount of patellar tendon shortening and the loss of knee flexion angle (ROM). (2) To evaluate the impact of shortening on Lysholm and Kujala functional scores. (3) To identify risk factors leading to severe shortening (e.g., AO fracture classification, fixation method, immobilization duration). |
