Carlos Rodriguez-Merchan, MD, PhD 1  \n1 Department of Orthopedic Surgery, La Paz University Hospital, Madrid, Spain  \nI  \nt has been reported that robotic arm-assisted arthroplasty ensures optimal implant position.1-3 In 2023, Poursalehian et al. reported a bibliometric  \nanalysis of publications on total knee arthroplasty (TKA) in the journal Archives of Bone and Joint Surgery, covering the period from 2018 to 2022. One of the hotspots in TKA research mentioned by the aforementioned authors in their article was robotic-assisted TKA (RA-TKA) .4  \nAccording to Khan et al, RA-TKA is foreseen to make up more than 70 % of all TKAs carried out in the USA by 2030.5 In this study two national databases (Nationwide Inpatient Database and National Ambulatory Surgery Service Database) from 2012 to 2020 were examined for conventional TKA (C-TKA) and RA-TKA utilizing ICD-10 and CPT codes. The use of RA-TKA increased from 0.01% in 2008 to 8.5% in 2020. It is expected that by 2030, RA-TKA will account for 70.1% of the 2,631,972 TKAs performed. CTKA had statistically significant higher rates of mechanical (1.8% vs. 0.7%), non-mechanical (30.1% vs. 24.9%), and infectious (1.8% vs. 0.7%) complications than RA-TKA. In addition, the lengthof stay(LOS) inpatients undergoing RATKA was shorter than inpatients undergoing C-TKA (1.9vs. 2.8 days, statistically significant difference) . However, the results of this study should be interpreted with caution, as it was retrospective, based on administrative codes that could lead to misclassifications, and did not include outpatient data prior to 2018.5  \nIt is currently still unknown whether the medium- and long-term results of RA-TKAare superior to those ofC-TKA. Therefore, the purpose of this Editorial has been to identify articles published in PubMed between January 1, 2025, and August 28, 2025, using the keywords “Robotic-assisted TKA 2025.” A total of 168 articles were found, of which only five were ultimately analyzed because they were considered tobe of the greatest interest in relation to the title of this Editorial.5-9  \nIn a systematic review and meta-analysis that included all reported randomized controlled trials (RCTs) from inception to August 2024, Mostafa et al. reported that RATKA achieved better mechanical alignment accuracy than C-TKA, but did not yield better short- to medium-term functional results. Besides, RA-TKA required longer  \nsurgical times. These authors also stated that the clinical benefits and cost-effectiveness of RA-TKA needed further assessment, particularly in long-term studies.6 However, this systematic review and meta-analysis has significant limitations. One of these is that it was quite difficult to compare studies due to the heterogeneity in the outcome measurement parameters and follow-up periods. The lack of long-term results in most studies did not allow fora correct assessment of the possible long-term benefits of the improved alignment provided by RA-TKA. In addition, the rapid evolution of robotic technology means that some previous studies may not have reflected the capabilities of current systems. For all these reasons, I agree with Mostafa et al. that the decision to use RA-TKA should be made with caution, taking into account its cost, the necessary learning curve, and the needs of each surgical team and institution. Future studies should focus on the long-term results of RA-TKA, its potential costeffectiveness, and its possible benefits in complex cases or revision surgeries.6  \nChen et al. found that C-TKA was non-inferior to RA-TKA at both short-term and long-term follow-up regarding implant survival, adverse events, and postoperative pain scores, while RA-TKA showed subtle improvements in functional outcome measures. In this systematic review and meta-analysis, Chen et al. found that at ten years postoperatively, survivorship rates in the C-TKA were 97%","cbCail1gp4dJ7C1G","https://ap.wps.com/l/cbCail1gp4dJ7C1G","pdf",552158,"English","# Robotic-assisted vs conventional TKA: evidence overview\n## Trends, databases, and early outcomes\n## Systematic reviews, meta-analyses, and limitations\n## Implant survival, revisions, and revision-risk considerations","[{\"question\":\"What is the main comparison focus between RA-TKA and C-TKA in this editorial?\",\"answer\":\"The editorial compares robotic-assisted total knee arthroplasty with conventional total knee arthroplasty in terms of implant positioning/alignment, complications, length of stay, functional outcomes, and long-term survival or revision-related endpoints.\"},{\"question\":\"What concerns affect how confidently the early database findings can be interpreted?\",\"answer\":\"The editorial notes that the key analysis is retrospective, based on administrative codes that may cause misclassification, and that outpatient data before 2018 were not included, so results should be interpreted with caution.\"},{\"question\":\"Why does the editorial recommend caution when deciding to use RA-TKA?\",\"answer\":\"It highlights remaining uncertainty about medium- to long-term superiority, limitations such as heterogeneity in outcome measures and follow-up durations, rapid robotic technology evolution, and the need to weigh cost and the learning curve for each surgical team and institution.\"}]","Robotic-assisted Total Knee Arthroplasty versus Conventional Total Knee Arthroplasty - Editorial | PDF",1790729720]
