探讨老年人行膝关节超声检查的意义

Discussion on the Signifi cance of Knee Joint Ultrasonography for Senior Citizens

目的探讨应用超声检查评价老年人膝关节软骨退行性变(退变)的临床意义。方法对北京市和平里街道安德路社区60岁以上的老年人,随机抽取233例(男102例,女131例)行膝关节超声检查,观察436个膝关节股骨髁间沟内侧斜面、髁间沟外侧斜面及髁间沟关节面软骨并分析、总结受检者软骨状况。结果 436个膝关节中,发生软骨退变381个(临床原发性膝骨关节炎(KOA)组205个,临床非KOA组176个),软骨退变率87.39%。临床KOA组,股骨髁间沟内侧斜面、外侧斜面及髁间沟软骨厚度测量值分别为(0.98±0.44)mm、(1.16±0.51)mm、(1.71±0.55)mm;临床非KOA组分别为(1.53±0.40)mm、(1.64±0.40)mm、(2.05±0.42)mm。结论超声检查对评价老年膝关节软骨退变状况具有一定的临床意义。

Objective To investigate the clinical significance of ultrasonography for senior citizens with degenerative knee cartilage problems. Methods Among senior patients who were 〉 60 years old and living inthe Ande Road Community （Hepingli Street, Beijing）, 233 cases were randomly selected （Male： 102 cases; Female： 131 cases） and underwent knee joint ultrasonography. Then, observation of ultrasonograms obtained from 436 knee joints was made including the inner, outer sloping surfaces and the articular cartilage of the femoral intercondylar groove. Based on the observation results, analysis and summaries were further made concerning the patients＇ cartilage conditions. Results In this study, 381 degenerative knee cartilages out of 436 knee joints were found with the degeneration rate accounting for 87.39% and could be divided into two groups according to their clinical features： 205 cases in KOA （Knee Osteoarthritis） Group and 176 in Non-KOA Group. The inner, outer sloping surfaces and the articular cartilage of the femoral intercondylar groove were measured as （0.98±0.44）mm, （1.16±0.51） mm, （1.71±0.55） mm in KOA Group versus （1.53±0.40） mm, （1.64±0.40） mm, （2.05±0.42） mm in Non- KOA Group respectively. Conclusion Ultrasonography is of certain clinical significance in evaluation of degenerative knee cartilage problems for senior citizens.
