目的 调查髌骨运动轨迹的异常改变与髌骨软化症之间是否存在相关性.方法 收集2006年3月至2008年12月在我院临床诊断为髌骨软化症的患者60例,共计79侧膝关节,摄屈膝30°轴位片及侧位片,进行髌骨高度、髌骨指数、髌骨厚度、适应角、髌股关节指数、外侧髌骨角、髌骨倾斜角、股沟角、髌骨外侧偏移率测量,并与对照组(60例膝关节无症状的志愿者)相应数据进行比较.同时进行主成分分析,得出相关性方程.结果 髌骨软化组股沟角、髌股关节指数、外侧髌骨角、髌骨倾斜角与对照组比较,差异均有统计学意义[(137°±6°)比(132°±4°),P ＜0.05；(1.05±0.23)比(1.49±0.22),P＜0.01；(7.6°±2.4°)比(5.3°±2.3°),P＜0.05；(10.8°±2.7°)比(14.6°±3.3°),P＜0.01],主成分分析显示反映髌骨轨迹异常改变的9个指标中第一主成分有5个指标,它们反映髌骨软化症患病程度的系数依次为髌股关节指数、外侧髌骨角、髌骨指数、股沟角和髌骨高度.结论 髌股关节对合关系及髌骨运动轨迹的异常改变与髌骨软化症存在密切相关性,髌骨在屈膝30°位时更易向外侧脱位,对临床上怀疑髌骨软化症的患者应行屈膝30°位轴位片及侧位片拍摄,以便早期作出诊断,及时给予治疗.
目的 調查髕骨運動軌跡的異常改變與髕骨軟化癥之間是否存在相關性.方法 收集2006年3月至2008年12月在我院臨床診斷為髕骨軟化癥的患者60例,共計79側膝關節,攝屈膝30°軸位片及側位片,進行髕骨高度、髕骨指數、髕骨厚度、適應角、髕股關節指數、外側髕骨角、髕骨傾斜角、股溝角、髕骨外側偏移率測量,併與對照組(60例膝關節無癥狀的誌願者)相應數據進行比較.同時進行主成分分析,得齣相關性方程.結果 髕骨軟化組股溝角、髕股關節指數、外側髕骨角、髕骨傾斜角與對照組比較,差異均有統計學意義[(137°±6°)比(132°±4°),P ＜0.05；(1.05±0.23)比(1.49±0.22),P＜0.01；(7.6°±2.4°)比(5.3°±2.3°),P＜0.05；(10.8°±2.7°)比(14.6°±3.3°),P＜0.01],主成分分析顯示反映髕骨軌跡異常改變的9箇指標中第一主成分有5箇指標,它們反映髕骨軟化癥患病程度的繫數依次為髕股關節指數、外側髕骨角、髕骨指數、股溝角和髕骨高度.結論 髕股關節對閤關繫及髕骨運動軌跡的異常改變與髕骨軟化癥存在密切相關性,髕骨在屈膝30°位時更易嚮外側脫位,對臨床上懷疑髕骨軟化癥的患者應行屈膝30°位軸位片及側位片拍攝,以便早期作齣診斷,及時給予治療.

Objective To investigate the correlation between patella maltracking and chondromalacia of patella.Methods Sixty patients (79 knees)with chondromalacia of patella were collected from March 2006 to December 2008,and 60 volunteers without any symptom of knee joint were enrolled in this study.All of 120 cases were taken axial and lateral X-ray radiographies with knees flexing at 30 degree.Parameters (patella height,patella index,patella thickness,adaptation angle,patellofemoral joint index,lateral patella angle,angle of patella crab,condyles intergroove angle of femur and the rate of lateral patella excursion)were measured and analyzed.Results There were significant differences between chondromalacia of patella group and control group in condyles intergroove angle of femur,patellofemoral joint index,lateral patella angle and angle of patella crab[(137° ± 6°)vs (132° ± 4°),P＜0.05;(1.05 ±0.23)vs (1.49 ±0.22),P＜0.01;(7.6° ±2.4°)vs (5.3° ±2.3°),P＜0.05;(10.8° ± 2.7°)vs (14.6° ± 3.3 °),P ＜ 0.01].Patellofemoral joint index,lateral patella angle,patella index,condyles intergroove angle of femur and patella height contained in first principal component,which showed the abnormal changes of patella maltracking and the severity of chondromalacia of patella.Conclusions There is a close correlation between chondromalacia of patella and patellofemoral joint apposition.Patella is much easier to dislocate to lateral when the knee is flexing at 30 degree.Patients should take axial and lateral X-ray radiographies with knees flexing at 30 degree to make correct diagnosis and treatment.
