Proponents of minimally invasive total knee arthroplasty (TKA) state accelerated patient recovery and increased patient satisfaction as advantages. However, retractors state a greater incidence of iatrogenic nerve injury, implant mal-positioning and increased rates of revision. This study compares the clinical and radiological outcomes of minimally invasive and conventional exposure TKA using a meta-analysis. A search of published and unpublished literature was performed. Eighteen studies including 1582 TKAs were reviewed: 822 minimally invasive versus 760 conventional exposure TKAs. The findings of this study suggest that whilst incision length was significantly smaller in MIS (p=0.001), and flexion range of motion was significantly greater following MIS (p=0.01), there was no statistically significant differences in all other clinical or radiological outcomes between MIS or conventional approach TKA surgery (p>0.05).
微创全膝关节置换术（TKA）的支持者称其优点是患者恢复加快且满意度提高。然而，牵开器使用者则指出医源性神经损伤、植入物位置不当的发生率更高以及翻修率增加。本研究采用荟萃分析比较微创和传统暴露式TKA的临床和放射学结果。对已发表和未发表的文献进行了检索。共纳入18项研究，涉及1582例TKA：822例微创TKA与760例传统暴露式TKA。本研究结果表明，虽然微创组的切口长度显著更小（p = 0.001），且术后微创组的屈曲活动范围显著更大（p = 0.01），但微创或传统入路TKA手术在所有其他临床或放射学结果方面均无统计学显著差异（p>0.05）。
