“…The importance of using knee bones in age estimation is overlooked and less researched compared to other bones such as skull, teeth, and hands bones [25]. A recent review highlighted the importance of establishing a population-specific criterion for chronological estimates of bone age [25]. This research is the first to be conducted in Jordan for estimation of knee bones and it encountered a number of inherited issues that limit the generalizability of study conclusions and the understanding of variations in epiphyseal fusion.…”

Background and Objectives: Bone age determination is a valuable method for forensic and disaster identifications of unknown human remains, as well as for medical and surgical procedural purposes. This retrospective research study aimed to determine the age based on epiphyseal fusion stages and investigate differences related to gender. Materials and Methods: X-rays of the knee were collected from medical imaging centers in hospitals in the south of Jordan and examined by two observers who determined the bone epiphyseal phase of closure for the femur, tibia, and fibula bone ends close to the knee based on a three-stage classification. Results: The main results revealed that females showed earlier epiphyseal union (Stage II) at the lower end of the femur and the upper ends of the tibia and fibula compared to males. In males, the start of complete union (Stage III) at knee bones was seen at the age of 17–18 years, while in females, it was seen at the age of 16–17 years. Additionally, knee bones showed complete union in 100% of males and females in the age groups 21–22 years and 20–21 years, respectively. Although females showed an earlier start and end of epiphyseal complete union than males, analysis of collected data showed no significant age differences between males and females at the three stages of epiphyseal union of the knee bones. Conclusions: Findings of the radiographic analysis of bone epiphyseal fusion at the knee joint are a helpful method for chronological age determination. This study supports the gender and ethnicity variation among different geographical locations. Studies with a high sample number would be needed to validate our findings.

Individuals age differently depending on a multitude of different factors such as lifestyle, medical history and genetics. Often, the global chronological age is not indicative of the true ageing process. An organ-based age estimation would yield a more accurate health state assessment. In this work, we propose a new deep learning architecture for organ-based age estimation based on magnetic resonance images (MRI). The proposed network is a 3D convolutional neural network (CNN) with increased depth and width made possible by the hybrid utilization of inception and fire modules. We apply the proposed framework for the tasks of brain and knee age estimation. Quantitative comparisons against concurrent MR-based regression networks illustrated the superior performance of the proposed work.

The Roche, Wainer, and Thissen (RWT) knee method was designed to assess maturity in living individuals, but is infrequently cited in studies of skeletal measures for legal age thresholds or estimation of age‐at‐death for forensic cases. We implement the RWT method using R scripts and analyze its utility in establishing an age threshold of 18 years. We fit the RWT model and verify its accuracy in estimating skeletal age against results and known age data provided by RWT. We also found the transition distribution for full skeletal maturity. Agreement between the RWT method and our implementation was good, with a maximum deviation of 0.03 years. The modes of transition to full skeletal maturity are 18.37 and 17.16 years for males and females. The corresponding Bayes factors are 5.73 and 1.77, indicating that complete skeletal maturity of the knee does not provide conclusive evidence of attainment of 18 years of age.
