Table 2 Outcomes in robotic-assisted UKA

From: Robotic-assisted unicompartmental knee arthroplasty: a review

Studies System Level of evidence Main findings
Kayani et al. [49] 2019 Mako III rUKA was associated with reduced postoperative pain, decreased opiate analgesia requirements, improved early functional rehabilitation, and shorter time to hospital discharge compared with conventional UKA.
Wong et al. [16] 2019 Mako III rUKA was not superior to conventional UKA in terms of functional scores, while was associated with longer operative time and cost and lower survivorship at short-term follow-up of 2 years.
Dretakis et al. [10] 2019 Mako III rUKA significantly improved range of motion and coronal plane alignment.
Gilmour et al. [13] 2018 Mako II More active patients may benefit from rUKA.
Canetti et al. [51] 2018 Navio III Robotic-assisted lateral UKA reduced the time to return to sports at pre-symptomatic levels when compared with conventional surgical technique (4.2 ± 1.8 months vs. 10.5 ± 6.7 months), with a comparable rate of return to sports (100% vs. 94%).
Blyth et al. [36] 2017 Mako II Robotic arm-assisted surgery resulted in lower median pain scores than those observed in the manual UKA group from the first postoperative day to week 8 postoperatively.
Marcovigi et al. [71] 2017 Mako III rUKA provided an improvement in terms of both clinical and technical results, and a low risk of postoperative complications.
Plate et al. [49] 2017 Mako IV Obesity had no effect on rUKA at a minimum follow-up of 24 months.
Hansen et al. [45] 2014 Mako III Robotic guidance did little to change clinical or radiographic outcomes, and average operative time was longer with an average of 20 min (p = 0.010).
