Summary: Nonunited fractures of the femoral shaft and distal femur can be successfully treated with stabilization, but for difficult cases, a pedicled medial femoral condyle (MFC) bone flap can provide vascularized autograft. This technique has gained widespread adoption and can be particularly helpful in low-resource environments or when microsurgical anastomosis is not possible.

Summary: This study examined the relationship between distal femoral morphology and noncontact ACL rupture and the differences between DR and MRI in evaluating distal femoral morphology. The findings showed that a decreased LFCI is associated with an ACL rupture, and both DR and MRI measurements can effectively predict the risk of ACL rupture.

Summary: Sex determination is a synthesis of many molecular events that drives a community of cells towards a coordinated tissue fate, even without inherited genetic determinants. Recent studies suggest that epigenetic regulation and temperature can play a significant role in initiating and stabilizing the sex determination pathway. Investigations should focus on cellular processes that can synthesize multiple inputs and drive a coordinated response, rather than a singular regulator of sex determination.

Summary: This retrospective case-control study investigated the association between LFCR measured by MRI and the risk of noncontact ACL injury. The results showed that increased LFCR was related to an increased risk of noncontact ACL injury. LFCR and LTH were identified as sensitive risk factors for noncontact ACL injury, which can help clinicians identify individuals prone to ACL injury and implement prevention and intervention measures.

Summary: This study explores the links between mechanisms of transitions in sex determination and sex chromosome evolution by studying the rare species Carinascincus ocellatus and its relative Liopholis whitii. Unique and conserved regions of the Y chromosome were identified among different populations of C. ocellatus, with no evidence of sex chromosome homology between C. ocellatus and L. whitii, indicating independent evolutionary origins. The study also discusses sex chromosome homology within the subfamily Lygosominae and proposes connections between sex chromosome evolution, sex determination transitions, and karyotype evolution.

Summary: This study aimed to determine whether the lateral femoral condyle is hypoplastic in genu valgum by evaluating the severity of the coronal deformity. The results showed no significant differences in mAPCL, lAPCL, mCT, lCT, mPCH, or lPCH across different mechanical-axis groups. VCA, aLDFA, DFT, and mCV/lCV differed significantly, with smaller VCA and aLDFA when valgus exceeded 10 degrees. In conclusion, genu valgum does not seem to be associated with hypoplasia of the lateral condyle.

Summary: Wildlife exhibits various sex-determination systems, with both sex chromosomes and environmental temperatures playing a role in individual sexual development. Amphibians and reptiles are becoming important for studying the causes and consequences of this variability, and we have created a comprehensive database called HerpSexDet, featuring data on genetic and temperature-dependent sex determination, as well as reports on sex reversal for 192 amphibian and 697 reptile species. This database enables comparative studies on the evolution of sex determination and its effects on species traits and conservation status, and aids in identifying species for future research on environmentally driven sex reversal.

Summary: The genetics of sex determination in Drosophila melanogaster has a rich history intertwined with the foundation of the Genetics discipline. By studying the sex determination mechanisms in fruit flies and other insect species, evolutionary patterns of sex-determining pathways have been revealed, along with the significant link between scientific research and technological advances.

Summary: Fractures of the proximal tibia can be treated by filling the bone void using techniques such as iliac autograft, allograft, or synthetic bone graft substitutes. In this study, a minimally invasive technique was used to harvest bone graft from the distal femur, which was then used to fill the void in proximal tibial fractures. The results showed successful incorporation of the bone graft into the tibia, good healing at the harvest site, and no complications.

Summary: This study establishes Hydractinia as a reliable non-bilaterian model system for the study of sex determination and the evolution of sex chromosomes. By generating a linkage map and utilizing deep sequencing, the researchers found pseudoautosomal and non-recombining regions on the X and Y chromosomes of Hydractinia. They also identified genes in the non-recombining region that are specifically expressed in the male gonad. Additionally, the study observed enhanced recombination rates in the female genome and determined that Hydractinia has a haploid chromosome number of n = 15.

Summary: This study reviewed previous research on the anatomy and biomechanics of the sacroiliac joint (SIJ), finding that there is limited movement in the SIJ but also significant pelvic incidence (PI) changes. The minimum and maximum movement angles for the SIJ were found to be 0.01 degrees and 2.27 degrees respectively, while PI changes ranged from 0 to 9 degrees. Further study on SIJ movement and PI changes from a biomechanical perspective is recommended for a better understanding.

Summary: The study found that vastus medialis (VM) impairment in knee joints undergoing total knee arthroplasty (TKA) may increase the risk of posterior dislocation of the tibia. The altered muscle distribution can lead to changes in joint reaction forces and moments, potentially causing instability and functional issues.

Summary: In this study, we analyzed the relationship between femoral tunnel length, graft bending angle, and stress with respect to tunnel entry position and ASR during ACLR surgery. Results showed that ASR did not affect femoral tunnel length, with smaller ASR leading to higher graft bending angle and larger ASR causing greater stress in the graft.

Summary: This study investigated the isometricity of the fovea ulnaris during forearm rotation in vivo. Three-dimensional reconstruction models of wrist CT images were used to analyze the position of the ulnar head and rotation center. The results showed that the fovea ulnaris is not consistently isometric during forearm rotation, with the rotation center shifting ulnarly with increasing translation of the ulnar head or forearm rotation.

Summary: The effect of medial meniscus posterior root (MMPR) repair during opening-wedge high tibial osteotomy (OWHTO) in terms of contact pressure (CP) and contact area (CA) was investigated using human cadaveric knee specimens. Repairing the torn MMPR decreased CP and increased CA, regardless of whether OWHTO was performed. The biomechanical advantage of repairing torn MMPR is maintained, irrespective of the degree of correction during OWHTO.

Summary: The study demonstrates that kinematically aligned total knee arthroplasty (KA TKA) better reproduces native knee biomechanics during mid-flexion compared to mechanically aligned total knee arthroplasty (MA TKA). Restoration of the joint line after KA TKA effectively replicates the native mid-flexion rollback and medial collateral ligament (MCL) strain, resulting in superior outcomes and more natural knee sensations for patients.
