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: Functional alignment (FA) is a novel philosophy in total knee arthroplasty (TKA) that respects individual bony and soft tissue phenotypes within defined limits. This paper focuses on describing the rationale and technique of FA in the valgus morphotype using an image-based robotic platform. The principles for valgus phenotype involve personalized pre-operative planning, restoration of native coronal alignment, dynamic sagittal alignment, matching implant sizing, and achieving defined soft tissue laxity through implant manipulation. FA aims to restore constitutional alignment and balance soft tissue laxity by considering individual anatomy and variations within predefined boundaries.

Summary: This retrospective study analyzed the outcomes of kinematic alignment total knee arthroplasty (KA-TKA) in valgus knees and compared them to non-valgus knees. The results showed that KA-TKA was effective in relieving pain and improving function in both groups, with slightly better outcomes in the non-valgus group.

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: This study compares the variation in native joint line in primary total knee arthroplasty (TKA) using neutral mechanical alignment (nMA) versus restricted kinematic alignment (rKA). The results show that nMA technique resulted in larger deviations from the native joint line compared to rKA technique.

Summary: This study compares the outcomes of conventional instrumentation and computer and accelerometer-based navigation tools in primary total knee arthroplasty. The results show that the navigation tools can improve postoperative alignment but do not improve complication rates or patient-reported functional outcomes.

Summary: This study retrospectively evaluated the postoperative outcomes of patients with complex EADs undergoing CAS-assisted constrained TKA, finding that the mechanical axis alignment was satisfactory, with improvements in KSS and range of motion. The use of CAS helped prevent anatomical conflicts and resulted in significant improvements in limb alignment and function postoperatively. No intra- or postoperative complications were reported.

Summary: This study aimed to evaluate postoperative changes in the coronal alignment of the ankle joint in patients undergoing total knee arthroplasty (TKA) for different degrees of knee deformity. The study found that there were significant changes in ankle alignment in the group with a valgus correction of 10 degrees or more. However, regardless of the degree of knee deformity correction, TKA did not result in significant changes in the tibiotalar tilt angle. These findings have important implications for assessing candidates for TKA and considering potential causes of postoperative ankle pain.

Summary: The study aimed to compare the outcomes of patients who underwent different sequences of ipsilateral total hip arthroplasty (THA) and total knee arthroplasty (TKA). Results showed that patients achieved similar favorable outcomes in clinical scores and survivorship regardless of the sequence of surgeries. Total joint arthroplasty can be performed safely with excellent outcomes in patients with a history of prior ipsilateral THA or TKA.

Summary: This study aimed to investigate the relationship between lower limb alignment and soft tissue balance after total knee arthroplasty (TKA). The results showed that the relaxation of soft tissues around the knee joint changed over time after TKA, but this change did not significantly affect the alignment of the lower limbs.

Summary: This study aimed to compare the coronal alignment changes under different posterior tibial slope using two methods of jig fixation. The results showed that with one pin fixation, the osteotomies shifted into varus, while with two pins fixation, the osteotomies shifted into valgus. There were significant differences in coronal alignment between the two fixation methods, and the slope changes affected the coronal alignment.

Summary: This study aimed to determine the predictors of failure to achieve minimal clinical important difference (MCID) for pain and disability in patients with mechanical neck pain (NP) after mechanical diagnosis and therapy (MDT)-based multimodal rehabilitation. The study found that factors such as age, diabetes, osteoporosis, response to repeated movement testing, treatment sessions, and compliance rate were associated with an increased risk of failure to achieve MCID.

Summary: This systematic review and meta-analysis investigated the prevalence of low back pain (LBP) among the Indian population. The results showed that the point prevalence of LBP was 48%, the annual prevalence was 51%, and the lifetime prevalence was 66%. Females, rural population, and elementary workers had the highest prevalence rates. These findings have important implications for policy-making related to the prevention and treatment of LBP in a large part of the global population.
