Restoration of the Joint Line Configuration Reproduces Native Mid-Flexion Biomechanics after Total Knee Arthroplasty: A Matched-Pair Cadaveric Study

Article Orthopedics

Kinematically aligned total knee arthroplasty restores more native medial collateral ligament strain than mechanically aligned total knee arthroplasty

Dohyung Lim et al.

Summary: KA TKA was found to restore a more native amount and distribution of MCL strain compared to MA TKA. This suggests that KA TKA may lead to better performance and more normal knee sensations for patients.

A comparison of utilization and short-term complications of technology-assisted versus conventional total knee arthroplasty

Trevor Simcox et al.

Summary: The utilization of technology-assisted total knee arthroplasty (TA-TKA) remains low among orthopedic surgeons. Compared with unassisted TKA (U-TKA), TA-TKA yielded improved perioperative and 30-day outcomes. However, the benefits and drawbacks of TA-TKA should be considered when choosing the surgical technique and technology for each patient.

Posterior stabilized total knee arthroplasty reproduces natural joint laxity compared to normal in kinematically aligned total knee arthroplasty: a matched pair cadaveric study

In Jun Koh et al.

Summary: The study found that after kinematic aligned total knee arthroplasty, using a posterior-stabilizing prosthesis can restore femoral rollback and soft tissue tension, similar to the effect of cruciate-retaining prosthesis.

Can Noise in the Feedback Improve the Performance of a Control System?

Maide Bucolo et al.

Summary: In linear control systems, the use of feedback loops can limit the bandwidth of the controlled system due to noise present in the feedback. To overcome this limitation, the concept of stochastic resonance can be utilized by introducing a simple nonlinearity in the controller to improve signal-to-noise ratio when tracking small-amplitude signals.

Comparative Study of Pinless Navigation System versus Conventional Instrumentation in Total Knee Arthroplasty

Prashant Pawar et al.

Summary: This study compared the functional and radiological outcomes of pinless navigation (PNA) total knee arthroplasty (TKA) performed using iAssist with conventional instrumented (CIN) TKA. The results showed no significant differences in mechanical axis alignment and component positioning between the two groups, but the PNA group had longer surgical time and fewer complications.

Comparison of post-operative three-dimensional and two-dimensional evaluation of component position for total knee arthroplasty

Osamu Tanifuji et al.

Summary: The study demonstrates that the difference in post-operative component alignment between 3D and 2D evaluation is significantly higher, highlighting the need for using the same co-ordinates' system for accurate assessment of post-operative component position.

Sensor-Assisted Total Knee Arthroplasty: A Narrative Review

Cheol Hee Park et al.

Summary: Wireless intraoperative load sensors have shown potential benefits in total knee arthroplasty, but further research is needed to determine their clinical advantages. Understanding load-sensing technology is crucial for the successful implementation of this new TKA technique.
