Clinical results of unicondylar knee arthroplasty can be improved by combining minimally invasive surgical techniques with computer-assisted navigation, according to results reported in the literature. The surgeons surveyed 23 patients who underwent a minimally invasive procedure and 15 patients who underwent a minimally invasive procedure with the use of computer-assisted navigation. The surgeons performed both minimally invasive surgical implantations using the Accuris unicondylar knee arthroplasty (onlay technique; Smith & Nephew, Memphis, Tenn) and the BrainLAB VectorVision uni-knee-system (Brain LAB, Inc, Westchester, Ill). Reported results showed significant improvement of the mechanical leg axis after a minimally invasive surgical procedure (range: 5.23 degrees-0.77 degrees) and a computer-assisted operation (range: 4.18 degrees-0.54 degrees). No significant change of slope and average angle of the implant in relation to the longitudinal tibial axis was reported. The study attempts to show that computer navigation used in minimally invasive unicondylar knee arthroplasty can improve positioning and axis calibration.
根据文献报道的结果，单髁膝关节置换术的临床效果可通过将微创外科技术与计算机辅助导航相结合来改善。外科医生调查了23例行微创手术的患者和15例行使用计算机辅助导航的微创手术的患者。外科医生使用Accuris单髁膝关节置换术（覆盖技术；Smith&Nephew，田纳西州孟菲斯）和BrainLAB VectorVision单膝系统（Brain LAB公司，伊利诺伊州韦斯特切斯特）进行了两种微创手术植入。报告结果显示，微创手术（范围：5.23度 - 0.77度）和计算机辅助手术（范围：4.18度 - 0.54度）后机械腿轴有显著改善。未报告植入物相对于胫骨纵轴的斜率和平均角度有显著变化。该研究试图表明，在微创单髁膝关节置换术中使用计算机导航可改善定位和轴线校准。
