“…It is widely acknowledged that the importance of a thorough knowledge of the patella and patellar ligament in modern surgical procedures is increasing (Baldwin and House, 2005;Yoo et al, 2007). A recently proposed method, which predicts the gender of unknown skeletal remains by discriminate function analysis of the patella has received much recognition (Introna et al, 1998;Scheuer, 2002;Mahfouz et al, 2007). Many research groups measured and analyzed certain parameters for this purpose: maximum height, maximum width, maximum thickness, height of articular facet, and medial and lateral articular facet breadth.…”

“…Many research groups measured and analyzed certain parameters for this purpose: maximum height, maximum width, maximum thickness, height of articular facet, and medial and lateral articular facet breadth. These simple measurements, combined with a gendering accuracy of 83.77%, would make this morphometric approach useful in forensic medicine and anthropology (Introna et al, 1998;Scheuer, 2002;Mahfouz et al, 2007).…”

“…In addition, morphological and morphometric features of certain bones display gender differences (Introna et al, 1998;Scheuer, 2002;Mahfouz et al, 2007). Both the patella and patellar ligament have been analyzed in adults and have been found to exhibit such differences (Grelsamer and Meadows, 1992;Miller et al, 1996;Introna et al, 1998;Biedert and Albrecht, 2006;Yoo et al, 2007;Mahfouz et al, 2007).…”

These data are essential for a full understanding of knee biomechanics and may be relevant to forensic science and anthropology as well (Kemkes-Grottenthaler, 2005;Mahfouz et al, 2007).…”

The morphometry of patella and patellar ligament during the fetal period

et al. 2010

This study aims to determine the development and morphology of the patella and patellar tendon and to obtain morphometric data about these structures during the fetal period. One hundred five human fetuses (55 males and 50 females) aged 9-40 weeks were used in this study. Fetuses were divided into four groups between gestational weeks; Group I (9-12 weeks), Group II (13-25 weeks), Group III (26-37 weeks), and Group IV (38-40 weeks). The patella and patellar ligament were exposed via anatomical dissection; the dimensions (length, width, thickness) and the width of the lateral and medial articular surfaces of the patella, and the length and width of the patellar ligament, were measured using a Vernier's caliper. No significant differences were observed between genders or sides for any of the parameters (P > 0.05), and a significant correlation was found between gestational age and all parameters (P < 0.001). All parameters of the patella and patellar ligament were found to be different statistically between trimesters (P < 0.05). This study reveals the development, morphological changes, and the morphometric measurements of the patella and patellar ligament during the fetal period. We hope that the present results can be useful for future studies.

“…Kemkes-Grottenthaler (2005) also used the same method on 82 samples and gained 85% average accuracy (when sample size was not taken into consideration) [5]. Mahfouz and his co-workers (2007) used nonlinear classification methods on 228 samples and gained 90.9% overall accuracy [6]. Akhlaghi and his co-workers (2010) using 113 patellae from the fresh cadavers of Iranian population found the highest average accuracy of 92.9% [2].…”

Abstract:Recently a method which estimates the sex of unknown skeletal remains by discriminant functional analysis (DFA) of the patella bone has received much recognition. DFA equation on patella bone is available for South Italian population, Iranian population, Thai population, archeological sample of prehistoric period and also for South Africans of European ancestry. The aim of this study was to derive discriminant functional equation for sex determination from measurements of patella bones in North Indian population The authors have analyzed 31 skeletons (19 males and 12 females) of both sides from the collection in the Department of Anatomy, Post Graduate Institute of Medical Sciences, Rohtak. Seven measurements for both the sides were taken on 62 patella bones of males (19) and females (12). Parameters measured were maximum length, maximum width, maximum thickness, maximum height and width of external and internal articular facets. These measurements were used to determine sex by using discriminant functional analysis. The results of this study exclusively based on patellar dimensions can determine the sex of North Indian population when other long bones, skull and pelvis bones are not available or after major accidental deaths when long ones get fragmented. This discriminant function carried out by statistical analysis will be the future method for sex determination which needs basic data for this bone from their own population.

Sex Determination of Remains

Diagnosis of sex from the skeleton, when the genitalia are no longer visible, can be performed with good degrees of accuracy only on adult bones and is based mainly on the macroscopic observation of cranium and pelvis shape. In the cranium, areas such as the glabella, orbital margin, zygomatic arch, mastoid processes, nuchal crest, and the mandible are usually considered. Analysis of pelvic morphology usually shows a higher precision, in particular, observation of the sciatic notch and the subpubic angle. However, the size of many bones (such as the head of the radius, femur, and humerus) may also be useful in sexing and several regression equations have been developed for this specific function. DNA analysis also can be performed; however, it has higher costs and limits related to degradation and contamination.
