An anatomo-functional implant positioning technique with robotic assistance for primary TKA allows the restoration of the native knee alignment and a natural functional ligament pattern, with a faster recovery at 6 months compared to an adjusted mechanical technique

Sebastien Parratte et al.

Summary: The study compared ligament balancing, TKA alignment, implant positioning, and patellar tracking between the AFIP and aMA techniques in total knee arthroplasty. The results showed that the AFIP technique restored physiological ligament balance and had equivalent clinical outcomes compared to the aMA technique at 12 months.

A new robotically assisted technique can improve outcomes of total knee arthroplasty comparing to an imageless navigation system

Fabio Mancino et al.

Summary: This study compared the 1-year clinical outcomes of a new imageless robotically assisted technique with an imageless navigated procedure in total knee arthroplasty. The results showed that the imageless robotic assisted surgery was associated with longer operative time but better pain perception and improved range of motion compared to the imageless navigated surgery.

Higher satisfaction after total knee arthroplasty using restricted inverse kinematic alignment compared to adjusted mechanical alignment

Philip Winnock de Grave et al.

Summary: The purpose of this study was to compare the clinical outcomes of restricted inverse kinematic alignment (iKA) and adjusted mechanical alignment (aMA) techniques in robotic-assisted total knee arthroplasty (TKA). The results showed similar clinical outcomes between the two techniques at a 12-month follow-up, but the restricted iKA technique had better satisfaction and achieved higher OKS and satisfaction thresholds.

Elliot Sappey-Marinier et al.

Summary: This study compared clinical and radiological outcomes of kinematic alignment (KA) and mechanical alignment (MA) with a posterior-stabilized (PS) total knee arthroplasty (TKA) using a post-cam system. The results showed a higher risk of tibial implant loosening with KA compared to MA in short-term follow-up, suggesting caution in TKA design selection when performing KA.

Intraoperative pressure sensors improve soft-tissue balance but not clinical outcomes in total knee arthroplasty: a multicentre randomized controlled trial

S. J. MacDessi et al.

Summary: The aim of this study was to determine whether using intraoperative pressure sensors to achieve soft-tissue balance was more effective than manual balancing in improving outcomes in total knee arthroplasty (TKA). The study found that despite improved quantitative soft-tissue balance, there were no significant differences in clinical or functional outcomes two years after TKA.

Arithmetic hip-knee-ankle angle and stressed hip-knee-ankle angle: equivalent methods for estimating constitutional lower limb alignment in kinematically aligned total knee arthroplasty

Payam Tarassoli et al.

Summary: This study compared the arithmetic HKA and stressed HKA measurements using radiographs and computer-assisted navigation, and found no significant difference between the two methods. These findings further support the use of the preoperative arithmetic method and the intraoperative stressed HKA technique in restoring constitutional lower limb alignment in KA TKA.

The Impact of Surgeon Variability on Patient-Reported Outcome Measures, Length of Stay, Discharge Disposition, and 90-Day Readmission in TKA

SaTia T. Sinclair et al.

Summary: The study found a significant association between surgeons and 1-year patient-reported outcome measures, length of stay, discharge disposition, and 90-day readmission after total knee arthroplasty (TKA). Surgeon-related factors may play a stronger role in these outcomes than patient characteristics, suggesting variability among surgeons in terms of patient outcomes.

Clinical and Patient-Reported Outcomes of Medial Stabilized Versus Non-Medial Stabilized Prostheses in Total Knee Arthroplasty: A Systematic Review and Meta-Analysis

Reece Tso et al.

Summary: This systematic review and meta-analysis compared the outcomes of medial stabilized total knee arthroplasty (TKA) with non-medial stabilized TKAs. Results showed statistically significant differences in the FJS, ROM, and OKS between the groups, but these differences were not clinically significant. Future research using patient-reported outcome measures like the FJS is recommended.

Restricted Kinematic Alignment, the Fundamentals, and Clinical Applications

Pascal-Andre Vendittoli et al.

Summary: The rKA technique aims to reproduce the constitutional knee anatomy of the patient within a safe range, with principles including lower limb coronal orientation, joint line orientation, preservation/restoration of soft tissues tension/laxities, prioritization of femoral anatomy preservation, and selection of the pivot point for anatomical adjustment. An algorithm is used to facilitate decision-making and guide the stepwise surgical technique.

Specific case consideration for implanting TKA with the Kinematic Alignment technique

Charles Riviere et al.

Summary: While the majority of TKA cases can be performed with standard KA technique, there are specific situations where complex KA TKA cases may be more challenging and surgical technique adaptations are necessary to ensure good clinical outcomes. The proposed classification system aims to address six specific issues to improve the reliability of prosthetic implantation, enhance inter-surgeon communication, and benefit the teaching of the KA technique. This classification system is not exhaustive and will be further refined over time.

Using standard X-ray images to create 3D digital bone models and patient-matched guides for aiding implant positioning and sizing in total knee arthroplasty

Vincent Masse et al.

Summary: X-Atlas (TM) is a new imaging technology that creates 3D bone models using standard X-rays, allowing for accurate personalized surgical planning and prediction of implant size. Studies demonstrated the high accuracy of X-Atlas (TM) in reconstructing bone models, as well as the superior positioning accuracy of PSI guides compared to conventional instruments. Additionally, X-Atlas (TM) was able to predict implant sizing effectively, potentially improving surgical efficiency.
