Summary: The KJLO after TKA is strongly influenced by the distance between the feet, with KJLO changing by 3.7 degrees per 100 mm. Standardization of the distance between the feet is necessary for reproducible assessment of KJLO after TKA.

Summary: This study compared the hip-knee-ankle (HKA) angle values obtained on X-ray images (LSRs) before and after total knee arthroplasty (TKA) with those obtained during computer-assisted surgery (CAS). The results showed that LSRs overestimate deformity before TKA compared to CAS, and the two methods are not comparable after surgery.

Summary: In this study, a deep neural network was used to accurately predict the correct anatomical side of the knee in radiographs, achieving an accuracy of 99.8% and 99.9% in the internal and external validation cohorts, respectively.

Summary: The purpose of this study was to determine levels of quality for long leg standing radiographs (LSR) by quantifying and correlating the patella position and fibular head superimposition. The study found that a correct LSR should have a patella that is centered and facing forward, as well as a fibula head superimposition (FHS) with a ratio of 1/5 compared to the tibia. This study is the first to define quantitative metrics based on LSR analysis.

Summary: This study introduces a radiolucent X-ray grid for intraoperative alignment assessment and compares its reliability with long-standing radiographs. The results show a high correlation between the X-ray grid method and radiographs, suggesting the X-ray grid method is more reliable.

Summary: This study aimed to investigate the relationship between knee flexion (KF) in the standing position and the severity of spinal deformity and knee osteoarthritis. The results showed that compensatory changes due to spinopelvic malalignment, not knee osteoarthritis alone, mainly affected KF in the standing position. This provides important insights into the development mechanism of knee osteoarthritis.

Summary: In this study of end-stage ankle osteoarthritis patients, it was found that there are differences in measuring the tibiotalar angle (TTA) using the mechanical axis of the lower limb (MAL) and the anatomical axis of the tibia (AAT), with the difference strongly correlated with the MAL-MAT angle. The use of long leg radiographs to measure coronal plane ankle joint alignment, especially in cases with proximal deformity, is recommended for more accurate results.

Summary: This study aimed to assess the accuracy and reliability of standing lateral lumbar radiographs for measuring spinopelvic parameters, compared with whole-spine EOS (R) images. The results showed good measurement agreement between the two imaging methods and excellent reliability for observer's measurements.

Summary: The study demonstrates that the femorotibial angle can be used to evaluate lower limb alignment on limited non-weight-bearing short knee radiographs. For varus knees, measurements on NWB SKRs showed the best correlation with the hip-knee-ankle angle, while for neutral and valgus knees, NWB SKR measurements were insufficient for reliable calculation and quantification of coronal alignment of the lower limb.

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.
