Randomized Controlled TrialAccuracy of different navigation systems for femoral and tibial implantation in total knee arthroplasty: a randomised comparative study.
It remains to be established whether optical computed tomography (CT)-free and acceleration-based navigation systems differ in terms of implantation accuracy and clinical outcomes for total knee arthroplasty. This randomised prospective study compared the implantation accuracy of these two navigation systems in total knee arthroplasty. ⋯ In the tibial sagittal plane, there was a significant difference in the implantation accuracy, but its difference did not affect the clinical outcomes. Both navigation systems have clinically acceptable implantation accuracy.

Multicenter StudyImpact of intra-operative predictive ligament balance on post-operative balance and patient outcome in TKA: a prospective multicenter study.
New technologies exist which may assist surgeons to better predict final intra-operative joint balance. Our objectives were to compare the impact of (1) a predictive digital joint tensioning tool on intra-operative joint balance; and (2) joint balance and flexion joint laxity on patient-reported outcomes. ⋯ Use of a predictive joint tensioning tool improved the final balance in TKA. Improved outcomes were found in balanced knees; however, this improvement did not achieve the MCID, suggesting further studies may be required to define optimal balance targets. Limiting medial and lateral flexion laxity resulted in an increased likelihood of achieving the Patient Acceptable Symptom State for KOOS Pain.

ReviewVirtual and augmented reality for surgical training and simulation in knee arthroplasty.
Immersive virtual reality (IVR), augmented reality and mixed reality form a spectrum of extended reality technology integration that has gained popularity in orthopaedics recently. This review article examines the role of extended reality technologies in knee arthroplasty. ⋯ Extended reality technologies have a myriad of potential applications in orthopaedic surgery. Further research is needed to evaluate the cost-effectiveness of its incorporation into training programmes.
