The patella (kneecap) is the largest and best-known of the sesamoid bones, postulated to confer biomechanical advantages including increasing joint leverage and reinforcing the tendon against compression. It has evolved several times independently in amniotes, but despite apparently widespread occurrence in lizards, the patella remains poorly characterised in this group and is, as yet, complete...

The patella (kneecap) exhibits multiple evolutionary origins in birds, mammals, and lizards, and is thought to increase the mechanical advantage of the knee extensor muscles. Despite appreciable interest in the specialized anatomy and locomotion of palaeognathous birds (ratites and relatives), the structure, ontogeny and evolution of the patella in these species remains poorly characterized. Wi...

In this paper, we present a novel visualization approach for the quantitative analysis of knee movement patterns in time-varying data sets. The presented approach has been developed for the analysis of patello-femoral instability, which is a common knee problem, caused by the abnormal movement of the patella (kneecap). Currently, patello-femoral analysis is based on acquisitions performed durin...

This study aims to evaluate the functional outcomes for fixation of transverse patella fracture (TPF) using a transosseous suturing method with non-absorbable polyester suture. A retrospective case series was conducted on 37 patients who underwent open reduction and internal technique suture at Lower Limb Department, Hospital Traumatology Orthopaedics, Ho Chi Minh City, from 1/6/2020 1/6/2022. ...

Patellofemoral pain is characterized by pain behind the kneecap and is often thought to be due to high stress at the patellofemoral joint. While we cannot measure bone stress in vivo, we can visualize bone metabolic activity using (18) F NaF PET/CT, which may be related to bone stress. Our goals were to use (18) F NaF PET/CT to evaluate whether subjects with patellofemoral pain exhibit elevated...
