This study performed a health care utilization analysis between robotic arm assisted total knee arthroplasty (rTKA) and manual total knee arthroplasty (mTKA) techniques. Specifically, we compared (1) index costs and (2) discharge dispositions, as well as (3) 30-day (4) 60-day, and (5) 90-day (a) episode-of-care costs, (b) postoperative health care utilization, and (c) readmissions. The 100% Medicare Standard Analytical Files were used for rTKAs and mTKAs performed between January 1, 2016, and March 31, 2017. Based on strict inclusion–exclusion criteria and 1:5 propensity score matching, 519 rTKA and 2,595 mTKA patients were analyzed. Total episode payments, health care utilization, and readmissions, at 30-, 60-, and 90-day time points were compared using generalized linear model, binomial regression, log link, Mann–Whitney, and Pearson's chi-square tests. The rTKA versus mTKA cohort average total episode payment was US$17,768 versus US$19,899 (p < 0.0001) at 30 days, US$18,174 versus US$20,492 (p < 0.0001) at 60 days, and US$18,568 versus US$20,960 (p < 0.0001) at 90 days. At 30 days, 47% fewer rTKA patients utilized skilled nursing facility (SNF) services (13.5 vs. 25.4%; p < 0.0001) and had lower SNF costs at 30 days (US$6,416 vs. US$7,732; p = 0.0040), 60 days (US$6,678 vs. US$7,901, p = 0.0072), and 90 days (US$7,201 vs. US$7,947, p = 0.0230). rTKA patients also utilized fewer home health visits and costs at each time point (p < 0.05). Additionally, 31.3% fewer rTKA patients utilized emergency room services at 30 days postoperatively and had 90-day readmissions (5.20 vs. 7.75%; p = 0.0423). rTKA is associated with lower 30-, 60-, and 90-day postoperative costs and health care utilization. These results are of marked importance given the emphasis to contain and reduce health care costs and provide initial economic insights into rTKA with promising results.

“…Angeles activity level in Mako THA than those for manual THA, at a minimum of one-year follow-up [20]. Perets et al followed 162 patients undergoing rTHA and reported reduced pain, increased patient satisfaction, and improved functional outcomes as assessed using HHS and Forgotten Joint Score at a minimum two years follow-up [21]. To our knowledge, the present study is one of few to compare outcomes between rTHA and nTHA.…”

Background The purpose of this study was to compare the clinical outcomes of total hip arthroplasty (THA) using computer navigation systems (nTHA) and those of robotic arm-assisted THA (rTHA).Methods Thirty prospective subjects who underwent rTHA were clinically compared with 30 subjects who underwent nTHA. Clinical data (the surgical time, intraoperative blood loss, length of hospital stay, pain severity, number of days to independent walking, and Harris Hip Score (HHS) at discharge) and radiographic parameters (the inclination and anteversion angles) were statistically compared between the two groups. Results The surgical time, number of days to independent walking, and postoperative pain were significantly reduced in the rTHA group than in the nTHA group. The rTHA group showed a significantly higher postoperative HHS than did the nTHA group. No statistically significant difference was observed in radiographic parameters between the groups.Conclusion The surgical time, postoperative pain, and number of days to independent walking were significantly shorter, and the HHS at discharge was significantly higher in the rTHA group than in the nTHA group. Thus, as compared to nTHA, rTHA improved early clinical outcomes.

“…Robotic‐arm assisted technology has been shown to recreate the head center, offset and leg length more accurately when compared to manual technique. In a few published studies, robotic THA has been associated with improved patient reported outcomes, decreased dislocation rates, and high forgotten joint scores. However, these data have been on cohorts of patients with primary osteoarthritis of the hip.…”

Background: There is a lack of data concerning the use of robotic devices in more complex total hip arthroplasty (THA) cases, such as hip dysplasia, ankylosing spondylolysis, and post-traumatic arthritis.Case Presentation: This case study presented three cases in which the Mako robotic device was used to help accurately implement the surgical plan. The operations went smoothly. The position and angle of the acetabular shells were placed as planned without any complications related to the operation. Postoperative Harris Hip Scores were good in two patients and poor in the patient with ankylosing spondylitis. Robotic-arm assisted surgery may be considered for complex THA cases in order to optimize the accuracy of the reconstruction, especially in the absence of conventional boney landmarks.

Robot‐assisted total hip arthroplasty: Clinical outcomes and complication rate

Abstract: Robotic-arm-assisted THA demonstrates favourable short-term outcomes and does not result in a higher complication rate compared to non-robotic THA as reported by the literature.
