“…This study is also in line with the one presented by Figueroa et al [ 8 ]who focused on the reliability in reproducing the planned cuts with a robotic-arm system that incorporates robotic placement of the cutting jigs. In their study Figueroa et al [ 8 ] presented 173 TKA performed with an imageless passive robotic TKA. They compared intraoperative recorded cuts with postoperative CT scans for each case.…”

Purpose Over the last decade, robotic TKA gained popularity for improving the accuracy of implant positioning and reducing outliers in limb alignment comparing to conventional jig-based TKA. Hypothesis of this study was that this newly designed robotically assisted system will achieve a high level of accuracy for bone resection. Purpose of the study was to evaluate the accuracy of the system. Methods For this study, 75 knees in 75 patients were operated using a new, robotic system (ROSA ® Knee System; Zimmer Biomet, Warsaw, IN) with a Posterior Stabilized Total Knee Arthroplasty (Persona ® Knee System). The planned, validated and measured angles and cuts for the distal and posterior femur, for the proximal tibia and for the final coronal alignment on long standing x-rays were compared. Results A statistically significant difference was found only between the average planned and the average validated angle for femoral flexion, tibial coronal axis, medial and lateral cuts; the average difference was in any case below 1 mm or under 1 degree with SD < 1. No statistical difference was found between planned validated and measured cuts. Average difference between planned HKA and measured was 1.2 ± 1.1. No statistically significant difference was found. Conclusions The results of this study demonstrated that using this new surgical robot in total knee arthroplasty it is possible to perform accurate bone cuts and to achieve the planned angles and resections.

“…Currently, few studies have been published on the accuracy of intraoperatively measured component position in robotic-assisted TKA surgery. A study by Figueroa et al (2019) 4 analyzed intraoperatively reported position in the OMNIBotics robotic-assisted knee replacement (Corin, Tampa, FL), and compared this with postoperative CT. The results of this study found that a majority of intraoperative measurements were !2 degrees, with results ranging from 75% (tibial sagittal plane) to 97% (femoral sagittal plane).…”

Robotic-assisted technology in total knee arthroplasty (TKA) aims to increase implantation accuracy, with real-time data being used to estimate intraoperative component alignment. Postoperatively, Perth computed tomography (CT) protocol is a valid measurement technique in determining both femoral and tibial component alignments. The aim of this study was to evaluate the accuracy of intraoperative component alignment by robotic-assisted TKA through CT validation. A total of 33 patients underwent TKA using the MAKO robotic-assisted TKA system. Intraoperative measurements of both femoral and tibial component placements, as well as limb alignment as determined by the MAKO software were recorded. Independent postoperative Perth CT protocol was obtained (n = 29) and compared with intraoperative values. Mean absolute difference between intraoperative and postoperative measurements for the femoral component were 1.17 degrees (1.10) in the coronal plane, 1.79 degrees (1.12) in the sagittal plane, and 1.90 degrees (1.88) in the transverse plane. Mean absolute difference between intraoperative and postoperative measurements for the tibial component were 1.03 degrees (0.76) in the coronal plane and 1.78 degrees (1.20) in the sagittal plane. Mean absolute difference of limb alignment was 1.29 degrees (1.25), with 93.10% of measurements ≤3 degrees of postoperative CT measurements. Overall, intraoperatively measured component alignment as estimated by the MAKO robotic-assisted TKA system is comparable to CT-based measurements.

“…RATKA systems enable surgical resections by either constraining the saw to a specified anatomic plane during the resection [10,12,15e17], positioning a resection guide relative to the bone similar to previous CAS systems [13,14,18,19], or positioning a burring tool during milling of the resection surface [10,20]. All these approaches have proven efficacious for improving resection accuracy.…”
