不同膝关节腔注射入路的成功率对比及分析

Comparative analysis of the successful rate of different approach to the knee joint injection

目的比较经不同的穿刺入路行膝关节腔穿刺的成功率和一次进针比例。方法选取行膝关节腔穿刺患者100名,依次间隔1周行髌骨下方入路、髌骨内侧入路、髌骨外侧入路穿刺。比较三种穿刺入路的成功率和一次进针比例。结果髌骨下方入路成功率85%,髌骨内侧入路成功率93%,髌骨外侧入路96%。髌骨外侧入路和内侧入路与髌骨下方入路相比,均具有显著统计学差异(P<0.01)。髌骨下方入路一次进针比例92.94%,髌骨内侧入路59.14%,髌骨外侧入路41.67%。三种穿刺入路间均具有显著统计学差异(P<0.01)。结论膝关节腔穿刺,为提高成功率和避免过高穿刺难度,推荐从髌骨内侧方入路行关节腔穿刺。

Objective To compare the successful rate and difficult level of different ap- proaches of intra-articular injection. Methods 100 patients were recruited and treated with in- tra-articular through inferior approach, medial approach and lateral approach successively. Re- suits Successful rate of inferior approach was 85%, medial approach was 93%, lateral approach was 96%. One-time puncture rate of inferior approach was 92.94%, while that of medial ap- proach was 59.14%, lateral approach was 41.67%. Conclusion To gain higher successful rate and avoid superior puncture difficulty, medial approach of intra-articular injection is recom- mended.
