Summary: The aim of this research is to develop a low-cost autonomous system for robotic-assisted knee arthroplasty, with a novel image-free registration process to eliminate the need for radioactive scans. The system was tested on artificial tibia bones and compared to the Mako and BlueBelt systems, showing smaller mean and maximum errors.

Summary: This study evaluated the mid-term survivorship and patient-reported outcomes of robotic-assisted lateral unicompartmental knee arthroplasty (UKA). The results demonstrated high survivorship and excellent patient satisfaction with robotic-assisted lateral UKA, even in patients who did not meet classic indications.

Summary: The study found that robotic-assisted UKA has a lower revision rate compared to conventional UKA in short-term follow-up. There was no difference in the general complications rate between both groups. No specific complications due to the robotic-assisted system were observed.

Summary: This study investigated the feasibility of using pinless navigation for tibial component implantation in unicompartmental knee arthroplasty. The results showed that the pinless navigation technique and the conventional technique achieved similar results in positioning the tibial component, with negligible differences in surgical time.

Summary: Robotic assisted unicompartmental knee arthroplasty (RAUKA) is a successful approach that improves implant positioning accuracy, minimizes soft tissue injury, and enhances patient outcomes. This review provides an overview of the historical development, features of the robotic arm and navigation systems, and characteristics of contemporary RAUKA. It also compares conventional unicompartmental arthroplasty with RAUKA and discusses current challenges and future advancements in the field.

Summary: This retrospective study compared the outcomes of robotic-arm-assisted unicompartmental knee arthroplasty (RUKA) and conventional unicompartmental knee arthroplasty (CUKA). The study found that RUKA had better accuracy in component positioning and bone anatomical alignment, but longer surgical time and greater blood loss. However, there were no significant differences in the clinical outcomes of the two procedures.

Summary: This study retrospectively examined the relationship between pre-operative and postoperative alignment in robotic unicompartmental knee arthroplasty (UKA) and patient-reported outcome measures. The results showed that there was no significant difference in KOOS-JR change for patients with different degrees of deformity correction, and the degree of correction did not predict MCID achievement.

Summary: This study aimed to assess the feasibility of a micro-invasive bi-compartmental knee arthroplasty using both arthroscopic and robotic technologies. The procedure was successfully performed on cadaveric specimens, and promising intraoperative and postoperative results were obtained. Further clinical prospective studies are needed to confirm the feasibility and clinical outcomes of this surgery.

Summary: Accurate positioning of prosthetic components is crucial for successful medial unicompartmental knee arthroplasty (mUKA). This study evaluated the use of femoral CT-based landmarks for setting tibial rotation in image-based robotic-assisted mUKA and found that it reliably achieved congruent knee kinematics with minimal deviations. The mean tibia component rotation relative to the femoral landmark was +0.24 degrees.

Summary: In young patients with isolated medial compartment arthritis, the conversion rates to total knee arthroplasty are higher with unicompartmental knee arthroplasty (UKA) compared to proximal tibial osteotomy (PTO). However, the overall reoperation rate is higher with PTO, primarily due to complications and revision procedures. Overall survivorship is acceptable for both procedures.

Summary: This study compared the facility costs of robotic-assisted unicompartmental knee arthroplasty (RA-UKA) and conventional unicompartmental knee arthroplasty (UKA) using time-driven activity-based costing. The results showed that, despite the longer operative time, RA-UKA had lower overall facility costs.

Summary: Patient knowledge regarding robotic-assisted total knee arthroplasty (RA-TKA) is limited, and there is room for improvement in patient awareness and acceptance of this technology. Surgeon preference is associated with patients' attitudes and willingness towards robotic assistance.

Summary: This study aimed to assess the return to sport rate in patients who underwent CT-based robotic-assisted unicompartmental knee arthroplasty (RA-UKA) and evaluate the clinical performance and association between patients' sport activity levels and Patient Reported Outcome Measures after surgery. The study found that patients who participated in sports had higher activity levels and satisfaction after surgery.

Summary: The study found that patients who underwent knee arthroscopy within two years prior to unicompartmental knee arthroplasty (UKA) were more likely to experience UKA failure from aseptic loosening and require conversion to total knee arthroplasty (TKA) within two years post-UKA. Further research is needed to better understand this association, but clinicians should be cautious when performing knee arthroscopy in patients who may be indicated for future UKA.

Summary: The study found that over 50% of knee surgeons in the UK, Australia, and New Zealand perform less than 5% of UKA procedures yearly. Additionally, the majority of experienced knee surgeons are not meeting the recommended minimum thresholds, suggesting that these thresholds may not be feasible for most knee surgeons. Further research is needed to understand the reasons behind this.
