Between April 2018 and April 2020, a total of 61 patients with single\u2010level lumbar degenerative spondylolisthesis and treated with robot\u2010assisted OLIF (28 cases, 16 females, 12 males, mean age 50.4\u2009years) or robot\u2010assisted Mis\u2010TLIF (33 cases, 18 females, 15 males, mean age 53.6\u2009years) were enrolled and evaluated. All the pedicle screws were implanted percutaneously assisted by the TiRobot system. Surgical data included the operation time, blood loss, and length of postoperative hospital stay. The clinical and functional outcomes included Oswestry Disability Index (ODI), Visual Analog scores (VAS) for back and leg pain, complication, and patient's satisfaction. Radiographic outcomes include pedicle screw accuracy, fusion status, and disc height. These data were collected before surgery, at 1\u2009week, 3\u2009months, 6\u2009months, and 12\u2009months postoperatively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were no significantly different results in preoperative measurement between the two groups. There was significantly less blood loss (142.4 \u00b1\u200989.4 <jats:italic>vs<\/jats:italic> 291.5 \u00b1\u200972.3\u2009mL, <jats:italic>P<\/jats:italic> &lt;\u20090.01), shorter hospital stays (3.2 \u00b1\u20091.8 <jats:italic>vs<\/jats:italic> 4.2 \u00b1\u20092.5\u2009days, <jats:italic>P<\/jats:italic> &lt;\u20090.01), and longer operative time (164.9 \u00b1\u200956.0 <jats:italic>vs<\/jats:italic> 121.5 \u00b1\u200948.2 min, <jats:italic>P<\/jats:italic> &lt;\u20090.01) in OLIF group compared with Mis\u2010TLIF group. The postoperative VAS scores and ODI scores in both groups were significantly improved compared with preoperative data (<jats:italic>P<\/jats:italic> &lt;\u20090.05). VAS scores for back pain were significantly lower in OLIF group than Mis\u2010TLIF group at 1\u2009week (2.8 \u00b1\u20091.2 <jats:italic>vs<\/jats:italic> 3.5 \u00b1\u20091.6, <jats:italic>P<\/jats:italic> &lt;\u20090.05) and 3\u2009months postoperatively (1.6 \u00b1\u20091.0 <jats:italic>vs<\/jats:italic> 2.1 \u00b1\u20091.1, <jats:italic>P<\/jats:italic> &lt;\u20090.05), but there was no significant difference at further follow\u2010ups. ODI score was also significantly lower in OLIF group than Mis\u2010TLIF group at 3\u2009months postoperatively (22.3 \u00b1\u200910.0 <jats:italic>vs<\/jats:italic> 26.1 \u00b1\u200912.8, <jats:italic>P<\/jats:italic> &lt;\u20090.05). There was no significant difference in the proportion of clinically acceptable screws between the two groups (97.3% <jats:italic>vs<\/jats:italic> 96.2%, <jats:italic>P<\/jats:italic> =\u20090.90). At 1\u2009year, the OLIF group had a higher interbody fusion rate compared with Mis\u2010TLIF group (96.0% <jats:italic>vs<\/jats:italic> 87%, <jats:italic>P<\/jats:italic> &lt;\u20090.01). Disc height was significantly higher in the OLIF group than Mis\u2010TLIF group (12.4 \u00b1\u20093.2 <jats:italic>vs<\/jats:italic> 11.2 \u00b1\u20091.3\u2009mm, <jats:italic>P<\/jats:italic> &lt;\u20090.01).
