Searches of PubMed, Medline and Google Scholar were performed in October 2020 using PRISMA guidelines. Search terms included \u201crobotic\u201d, \u201cknee\u201d and \u201carthroplasty\u201d. The criteria for inclusion were published clinical research articles reporting the learning curve for RATKA and those comparing the component position accuracy, alignment and balancing techniques, functional outcomes, or complications with mTKA. There were 198 articles identified, following full text screening, 16 studies satisfied the inclusion criteria and reported the learning curve of rTKA (\n                    <jats:italic>n<\/jats:italic>\n                    =5), component positioning accuracy (\n                    <jats:italic>n<\/jats:italic>\n                    =6), alignment and balancing techniques (\n                    <jats:italic>n<\/jats:italic>\n                    =7), functional outcomes (\n                    <jats:italic>n<\/jats:italic>\n                    =7), or complications (\n                    <jats:italic>n<\/jats:italic>\n                    =5). Two studies reported the learning curve using CUSUM analysis to establish an inflexion point for proficiency which ranged from 7 to 11 cases and there was no learning curve for component positioning accuracy. The meta\u2010analysis showed a significantly lower difference between planned component position and implanted component position, and the spread was narrower for RATKA compared with the mTKA group (Femur coronal: mean 1.31, 95% confidence interval (CI) 1.08\u20131.55,\n                    <jats:italic>p<\/jats:italic>\n                    &lt;0.00001; Tibia coronal: mean 1.56, 95% CI 1.32\u20131.81,\n                    <jats:italic>p<\/jats:italic>\n                    &lt;0.00001). Three studies reported using different alignment and balancing techniques between mTKA and RATKA, two studies used the same for both group and two studies did not state the methods used in their RATKA groups. RATKA resulted in better Knee Society Score compared to mTKA in the short\u2010to\u2010mid\u2010term follow up (95%CI [\u2212\u20091.23, \u2009\u2212\u20090.51],\n                    <jats:italic>p<\/jats:italic>\n                    =0.004). There was no difference in arthrofibrosis, superficial and deep infection, wound dehiscence, or overall complication rates. RATKA demonstrated improved accuracy of component positioning and patient\u2010reported outcomes. The learning curve of RATKA for operating time was between 7 and 11 cases. Future well\u2010powered studies on RATKAs should report on the knee alignment and balancing techniques utilised to enable better comparisons on which techniques maximise patient outcomes.\n
