Robotic-assisted revision total knee arthroplasty: a novel surgical technique

Abstract

Background Revision total knee arthroplasty is a challenging procedure. The robotic-assisted system has been shown to enhance the accuracy of preoperative planning and improve reproducibility in primary arthroplasty surgeries. The aim of this paper was to describe the surgical technique for robotic-assisted revision total knee arthroplasty and the potential benefits of this technique. Method This single-centre retrospective study included a total of 19 patients recruited from April 1, 2021 to April 30, 2022. Inclusion criteria were patients who had Mako™ robotic-assisted revision total knee arthroplasty done within the study period with a more than 6 months follow-up. Statistical analysis was done using Microsoft Excel 16.0. Results All 19 patients were followed up for 6 to 18 months. All patients in this study had uneventful recoveries without needing any re-revision surgery when reviewed to date. Conclusion With the development of dedicated revision total knee software, robot-assisted revision TKA can be a promising technique that may improve surgical outcomes by increasing the accuracy of implant placement, and soft tissue protection and achieving a better well-balanced knee.

Robotic-Assisted Conversion of a Failed Medial Unicompartmental Knee Arthroplasty to Total Knee Arthroplasty

“…Indeed, several studies have reported more accurate cuts, component placement, deformity correction, as well as fewer soft tissue complications, and improved patient satisfaction 10,16 . Although there is abundant literature regarding RA primary UKA and TKA, there are limited studies evaluating the use of robotics in revision and conversion TKA [17][18][19] . Kalavrytinos et al first described a case of an 87-year-old woman with a malpositioned UKA with extreme varus deformity who underwent an RA conversion of failed UKA to TKA 14 Intraoperative image showing placement of bone graft on the tibial bone defect after implant removal.…”

Digital orthopedics in the new AI era: from ASIA aspect

“…There are several products that have been widely used in joint replacement worldwide, such as Mako, Rosa, Cori, etc. This trend is expected to continue as more hospitals adopt robot-assisted surgery and as the technology continues to improve [ 17 ]. The integration of AI in surgical procedures not only enhances precision but also reduces the risk of human error, leading to better patient outcomes.…”
