Summary: This study conducted cutting experiments on fresh bovine bones and simulated bones to investigate the impact of different saw blade shapes on cutting forces. Based on the findings, a blade design was proposed to suppress chip clogging, which successfully reduced cutting forces and maintained stable cutting performance.

Summary: This study reviewed the early results of using image-free robotic-assisted technology in knee arthroplasty. It found that robotic-assisted TKA achieved better lower limb alignment outcomes compared to conventional surgery, with similar functional recovery. However, robotic-assisted surgery required a longer implantation time but shorter hospital stay.

Summary: Current assessment methods for knee osteoarthritis (OA) lack comprehensive information to accurately predict outcomes. In this study, deep learning (DL) risk assessment models were developed using baseline knee MRI to predict the progression of knee OA to total knee replacement (TKR) over a 108-month follow-up period. DL models using MRI showed higher diagnostic performance than traditional models using clinical risk factors or knee radiographs. The ensemble DL models combining MRI and radiograph data achieved the highest AUCs, indicating superior predictive ability.

Summary: This study compared the accuracy of achieving proper lower limb alignment and component positions after total knee replacement (TKR) with image-free and image-based robotic-assisted TKR. The results showed that there were significant differences between the two robotic systems in the alignment of the femoral and tibial components. The image-free system was more varus, while the image-based system was more valgus in the coronal alignment. The image-based system also had a larger deviation from the planned posterior slope in the sagittal alignment of the tibial component.

Summary: Cracks are one of the most fatal faults of rotating blades, and the blade tip timing technique can be used to detect cracks early and ensure the safe operation of gas turbines. This article proposes a method of crack detection using BTT data, which can effectively diagnose cracks by studying parameters such as blade frequency, amplitude, and interblade distance.

Summary: The technical differences between simultaneous and staged total knee arthroplasties (TKAs) can affect the clinical and radiographic outcomes. The study found that the second knee in simultaneous TKAs had a higher risk of establishing the mechanical axis outside neutral compared to staged TKAs. Staged TKAs had an increased risk of deep venous thrombosis. There were no significant differences in perioperative complications and range of motion between the two procedures.

Summary: This study assessed the bone cuts accuracy of a total knee arthroplasty system with an active robotic arm and found that the system achieved accurate bone cuts regardless of the surgeon's experience level. Although biases were observed, especially in femoral proximal-distal and tibial anterior-posterior positions, overall error values were below acceptable thresholds.

Summary: The study compared the efficacy and accuracy of robotic-arm system, patient-specific instrumentation (PSI), and conventional total knee arthroplasty (TKA). Results showed that robotic-arm-assisted TKA had the least intraoperative bleeding but the longest operation time. In terms of postoperative radiographic results, both the robotic-arm system and PSI group had better angles compared to the conventional group. However, there were no significant differences in functional scores among the three groups. Therefore, the robotic-arm system offers a more minimally invasive and accurate approach to TKA.

Summary: The study found that robotic-assisted total knee arthroplasty (R-TKA) and manual total knee arthroplasty (M-TKA) have similar effects on improving patient-reported outcomes, with R-TKA potentially offering some early benefits in single-surgeon comparison. Variables such as surgical technique, implant fixation, and outcome measurement responsiveness are important factors to consider in future studies.

Summary: In an effort to increase patient satisfaction with total knee arthroplasty (TKA), surgeons are gradually moving away from traditional neutral mechanical alignment (MA) towards individualized alignment techniques. This review discusses the differences in alignment techniques for TKA, the concept of knee phenotypes, and comparative studies between MA and individualized alignment. It also provides guidance for surgeons on incorporating individualized alignment into their practice. Alignment and implant positioning are now central to TKA, and a more personalized approach is being explored by surgeons.

Summary: The study aimed to compare the outcomes of patients who underwent different sequences of ipsilateral total hip arthroplasty (THA) and total knee arthroplasty (TKA). Results showed that patients achieved similar favorable outcomes in clinical scores and survivorship regardless of the sequence of surgeries. Total joint arthroplasty can be performed safely with excellent outcomes in patients with a history of prior ipsilateral THA or TKA.

Summary: This meta-analysis compared patient reported outcome measures, infection, readmission, revision, deep vein thrombosis (DVT), and mortality rates of outpatient versus inpatient TKA. The outpatient group showed higher Oxford knee scores, while the inpatient group had higher rates of revision, mortality, and DVT. However, no significant differences were found in readmission and infection rates between the two groups. Further high quality clinical trials are needed to draw a reliable conclusion.

Summary: Surgeons with higher medial UKA usage have lower UKA revision rates but higher TKA revision rates. Overall, surgeons performing 1-5% UKA had the lowest TKA and combined UKA + TKA revision rates. However, there was no significant difference in OKS scores between different UKA usage groups.
