“…Patellae were also classified based on the dimensions of the articular facets. In the present study, it was found that the Type B patella was the most prevalent, which is in support of previous observations by Fucentese et al [14]. The patellar height is of fundamental importance for patellofemoral complaints, operations involving knee arthroplasty, anterior cruciate ligament or proximal tibial osteotomy [15].…”

“…Numerous variations in the size and shape of the patella exist (Williams et al, 2005). As described by Fucentese et al (2006), Wiberg (2005 defined three types of patellae according to the articular surfaces (Fucentese et al, 2006). In Type 1, the medial and lateral articular surfaces are concave and equal to each other.…”

“…The patella may have different shapes, some of which are correlated to patellar instability (Williams et al, 2005). Previous studies argue that morphological differences such as a narrow medial articular surface of the patella play a role in the pathogenesis of certain pathologies (Biedert and Albrecht, 2006;Fucentese et al, 2006;Teichtahl et al, 2007).…”

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.

“…In these patients, AKP is the result of patellar maltracking, PF impingement and subsequent increased PF pressures or cartilaginous lesions [13]. The importance of extensor mechanism deficiency, lower-limb malalignment and soft-tissue imbalance has been studied extensively, but the most persistent anatomic findings in patients with PF disorders are trochlear dysplasia and patella alta [14][15][16]. Trochlear dysplasia is a developmental condition in which the distal femur loses its normal concave shape and turns to an abnormal flat or even convex geometry.…”

Purpose The purpose of the present epidemiologic study is to record the radiographic presence of trochlear dysplasia and patella alta in patients who undergo anterior cruciate ligament (ACL) reconstruction as a potential underlying factor for postoperative anterior knee pain (AKP). Methods All consecutive cases of skeletally-mature ACLdeficient knees that would undergo ACL reconstruction in three different hospitals were prospectively included during a six-month period. Inclusion criteria were acute and subacute ACL injury with no previous ipsilateral knee operation. Patients with chronic ACL tears, prior-to-ACL-injury history of patellar instability or other PF disorders were excluded from the study. Results A total of 299 knees were included (mean age 32± ten years). Forty-four (14.7 %) knees had a positive 'crossing sign' in the lateral X-rays and 255 (85.3 %) had no sign of trochlear dysplasia (p<0.01). Among the cases with trochlear dysplasia, 41 (93 %) had type A trochlear dysplasia with the presence only of the 'crossing sign' and three (7 %) had type C trochlear dysplasia. Patellar height results included a mean Caton-Deschamps index of 1.0± 0.14 (0.5-1.4). Twenty (6.6 %) knees had an index of less than 0.8, and two (0.6 %) knees had an index less than 0.6. In contrast, 15 (5.0 %) knees had an abnormal value of more than 1.2, indicating patella alta. ConclusionsThe most important finding of the study is the increased prevalence of trochlear dysplasia and patella alta in patients with ACL injury, when compared to the incidence of trochlear dysplasia and patella alta in the general population in the literature. This finding could sound as an alert of a possible additional risk factor for post-operative anterior knee pain after ACL reconstruction.
