Summary: This study evaluated the accuracy of an accelerometer-based navigation system for tibial resection during total knee arthroplasty. The results showed that the system did not improve the accuracy of the tibial cut compared to the conventional technique, but it restored the tibial slope.

Summary: The precision of bony resections during total knee arthroplasty (TKA) using different computer-assisted technologies was compared. A retrospective review was conducted on patients who underwent TKA using an imageless accelerometer-based handheld navigation system or computed tomography-based large-console surgical robot. The study found a small but statistically significant difference in the precision of the distal femoral resection between the handheld and robotic groups, but this may not be clinically significant. There were no significant differences in the precision of the tibial resection or overall precision between the groups.

Summary: This study analyzed the long-term survival rate and clinical outcomes of a NexGen LPS knee system and investigated the effect of component alignment parameters on clinical scores and patient satisfaction. The results showed that the NexGen LPS-Flex knee system had a satisfactory implant survival rate of 95.1% in 13.2 years, and the fixed bearing design had favorable results. On X-ray evaluations, the presence of two or more outlier components in the same knee led to a deterioration in patient satisfaction and clinical outcomes.

Summary: The number of Total knee arthroplasty (TKA) procedures is expected to increase significantly in the United States. Traditional TKA procedures have limitations in restoring full knee function, leading to patient dissatisfaction. Kinematic alignment (KA) can restore the natural knee anatomy but may increase implant stress and risk of complications. Restricted kinematic alignment (rKA) techniques can improve patient outcomes. Personalized Alignment (TM) is an advanced version of rKA that uses robotic assistance to recreate patient anatomy and improve clinical outcomes.

Summary: The study aimed to determine the major factor contributing to varus osteoarthritic knee and its surgical implications in total knee arthroplasty. The results revealed that proximal tibia deformity was the major contributor to osteoarthritic varus knee alignment, suggesting that correction should primarily be made on the tibia during the surgery.

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: Computer-assisted navigation and robotic-assisted methods in total knee arthroplasty can improve mechanical and component alignment. However, compared to conventional surgery, the advantages of these new technologies in patient-reported outcome measures are not significant, with only a minority of studies reaching clinical significance.

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: 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 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 investigated femoral component alignment in patients undergoing soft tissue-guided, navigated TKA. Results showed that with a mechanically aligned tibial component and tensioned soft tissues, the femoral component was placed at an average of 1.7 degrees varus in the coronal plane, aligning with the preoperative distal femoral joint line. Satisfactory knee function and excellent pain relief were demonstrated postoperatively based on KOOS and KSS scores.

Summary: A new robotic-assisted total knee arthroplasty system was compared to conventional TKA in terms of short-term effects and clinical outcomes. The robotic-assisted system showed better alignment and lower rate of malalignment compared to conventional techniques. The effectiveness of the system varied depending on the severity of preoperative lower extremity alignment deviations.

Summary: This study aimed to investigate the relationship between acute changes in the systemic inflammatory response (SIR) and thiamine and magnesium dependent enzyme activity in patients undergoing elective knee arthroplasty. The findings showed that pre-operatively TDP and magnesium concentrations were normal, but post-operatively TDP concentrations increased while magnesium concentrations decreased. Thiamine and magnesium could be potentially modifiable therapeutic targets to modulate the host inflammatory response.

Summary: This study investigates the prevalence and causes of graft impingement during ACL reconstruction surgery. The results show that impingement requiring repair occurs in a significant number of cases. The tunnel position does not correlate with the amount of impingement. The size of the intercondylar notch is associated with the degree of impingement.

Summary: This systematic review with meta-analysis demonstrates that ACL repair with internal bracing is a safe technique for the treatment of proximal ruptures, with a failure rate of 10.4%. Subjective scores and clinical laxity testing also showed satisfactory results. Therefore, ACL repair with internal bracing should be considered as an alternative to ACL reconstruction for acute proximal tears, offering the potential benefits of retained native tissue and proprioception, while avoiding the need for graft harvest.

Summary: This systematic review compares the precision of component positioning, patient-reported outcome measures, complications, survivorship, cost-effectiveness, and learning curves between MAKO robotic arm-assisted unicompartmental knee arthroplasty (RAUKA) and manual medial unicompartmental knee arthroplasty (mUKA). The review found that MAKO RAUKA has better precision in implant positioning, but no improvement in patient-reported outcome measures. In addition, MAKO RAUKA is shown to be cost-effective, but this is related to the volume of surgeries.

Summary: This study compares the ten-year revision rates and patient-reported outcome measures of electromagnetically (EM) navigated and conventional total knee arthroplasty. The results show that there is no difference in revision rates or clinical outcomes between the two methods after ten years of follow-up. Patients who received EM navigated surgery had better outcomes at 3 months post-operatively, but the outcomes were equivalent between the two interventions from 1 to 10 years post-operatively.

A retrospective cohort multicenter study was conducted, analyzing a case series of HTO's performed by four surgeons over a 14-year period. The results showed comparable survivorship at five and ten year follow-up, with an association found between age and larger corrections requiring bone graft.

Summary: The prevalence of disabling conditions is increasing globally, and the limited workforce cannot deliver intensive rehabilitation. Technology provides tools for self-rehabilitation but access is limited due to barriers such as cost and poor design. A new centre has been established to develop accessible rehabilitation technology through a co-creation model, currently undergoing testing with stroke survivors, with the potential to revolutionize the way rehabilitation is delivered.
