“…13,14 While literature on the efficacy of robotic-assisted knee arthroplasty exists, these studies often focus on specific physical parameters of the procedure. [15][16][17] There remains a paucity of literature addressing the general trends of robotic-assisted knee arthroplasty procedures.…”

Recent technological advancements have led to the utilization of robotic-assisted knee arthroplasty (raKA) in the operating room. Methods: All patients who underwent knee arthroplasty from 2009 to 2013 in NYS SPARCS were reviewed. raKAs and non-raKAs were compared for utilization and institutional trends. Results: Robotic-assistance increased by 500%. 80% of raKAs were performed in teaching hospitals. The trend increase was greater in teaching hospitals. Blood transfusion rates differed between raKA and non-raKA (6.6% vs. 10.9%, p < 0.001). Conclusion: raKA utilization increased in NYS, moreso within teaching hospitals. raKA transfusion rates were lower but higher in teaching hospitals, potentially related to learning curve.

“…Since no ligament release is performed in UKA, a precise osteotomy could result in preservation of the appropriate ligament balance. Several previous studies have reported that navigation- and robotic-assisted UKAs improve the accuracy and survival following surgery 26 , 27 . To improve osteotomy accuracy and for achieving appropriate ligament balance, a widespread use of navigation- and robotic-assisted UKAs may be important.…”

We analyzed the implantation effects on cruciate ligament force in unicompartmental knee arthroplasty (UKA) and determined whether kinematics is associated with the cruciate ligament force. We examined 16 patients (17 knees) undergoing medial UKA. Under fluoroscopy, each participant performed a deep knee bend before and after UKA. A two-dimensional/three-dimensional registration technique was employed to measure tibiofemoral kinematics. Forces in the anteromedial and posterolateral bundles of both the anterior cruciate ligament (aACL and pACL) and the anterolateral and posteromedial bundles of the posterior cruciate ligament (aPCL and pPCL) during knee flexion were analyzed pre- and post-UKA. Correlations between changes in kinematics and ligament forces post-UKA were also analyzed. Preoperatively, the aACL forces were highly correlated with anteroposterior (AP) translation of the lateral condyles (Correlation coefficient [r] = 0.59). The pPCL forces were highly correlated with the varus–valgus angulation (r = − 0.57). However, postoperatively, the PCL forces in both bundles were highly correlated with the AP translation of the medial femoral condyle (aPCL: r = 0.62, pPCL: r = 0.60). The ACL and PCL forces of the knees post-UKA were larger than those of the knees pre-UKA. Kinematic changes were significantly correlated with the cruciate ligament force changes.

“…[24][25][26][27] To improve the accuracy of prosthetic implantation, surgical instruments have been constantly improved, and the navigation system has been clinically applied. 10,12,13 However, clinical applications are dependent on the surgeon's perception and experience in identifying anatomical landmarks, which may be relatively ambiguous and subject to errors. The high cost and complexity of the navigation system also limits its practical application.…”

“…The high cost and complexity of the navigation system also limits its practical application. 10,13,17 PSI based on either magnetic resonance imaging (MRI) or CT scans was recently introduced to TKA and proven to aid in not only improving prosthesis position but also decreasing Table 2 Proportion of radiographic parameter outliers in the patient-specific instrumentation and conventional instrumentation groups…”

“…To improve the accuracy of prosthesis implantation and assist UKA, the use of robots and navigational systems has been reported. [10][11][12][13] However, they present a long learning curve, long surgical times, high cost, and tracker bias. 3,14 Recently, a technological tool that has received significant attention is patient-specific instrumentation (PSI) for knee arthroplasty, [15][16][17] but there is a scarcity of literature documenting the use of PSI in UKA.…”

The purpose of this study is to develop and validate a novel patient-specific navigational template for unicompartmental knee arthroplasty (UKA). A total of 120 patients who underwent UKA were randomized and divided into the conventional method and navigational template groups. In the navigational template group, patient-specific navigational templates were designed and used intraoperatively to assist 60 patients with UKA. Information on operation time and blood loss was recorded by an independent operating room nurse. After surgery, the positions of the prostheses were evaluated using X-rays. All navigation templates were found to fit its corresponding biomodel appropriately without any free movement. The navigational template exhibited significantly better accuracy than the conventional method. Statistically significant differences in the femoral prosthesis flip angle, femoral prosthesis flexion angle, and tibial plateau varus and valgus angle were observed between the two groups (p = 0.022, 0.042, 0.043, respectively). In addition, the mean operation time was statistically and significantly lower in the navigational template group than in the conventional group (p = 0.035). This study introduces a novel navigational template to UKA, the accuracy of which is proven by clinical operation. This is a Level III, therapeutic study.
