An electromyographic investigation ofpatients with subluxation ofthe patella has been carried out on the parts of the extensor apparatus which actively contribute to the alignment of the patella, both before and after the operation to correct this disorder. The electromyographic pictures have revealed a sharp fall in the activity of the vastus medialis, with full recovery to normal values after...

OBJECTIVE Lead exposure in adults is associated with worse cognitive function in cross-sectional and longitudinal studies. Previous studies have mainly examined relations with blood lead or cortical bone lead; few have examined trabecular bone lead. METHODS We performed a cross-sectional analysis of the relations of patella lead and other lead biomarkers with measures of neurobehavioral and p...

INTRODUCTION Isolated traumatic fractures of both Patellae, occurring at the same time, in an otherwise healthy person, are very rare. The Patella, as a subcutaneous and a cancellous bone, is vulnerable to injury. However, simultaneous injury to both Patellae without the involvement of any other bony injuries occurs infrequently, and only a few cases have been reported in the literature. CASE...

Background There is a paucity of data to guide management of the patella in revision total knee arthroplasty (RTKA). The purpose of this study was to review our experience with patellar management in RTKA. Methods We retrospectively reviewed 422 consecutive RTKAs at a minimum of 2 years (mean, 42 months). Patellar management was guided by a classification that considered stability, size, and ...

Background: The incidence of inferior pole fractures of patella is around 5% and the various treatment options include tension band wiring, circumferential wiring, or use of screw 1 . The traditional recommendation for severly comminuted inferior pole fractures is excision of the comminuted pole followed by reattachment of the patellar tendon with transosseous suture to the superior fragment 2 ...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2015-209942 DESCRIPTION Quadriceps tendon (QT) ruptures are uncommon injuries that predominantly affect middle-aged men. Ruptures occur as a result of direct or indirect trauma to the knee with a powerful eccentric contraction of the QT being the most frequent ca...

Isolated osteomyelitis of the patella is a rare condition mainly occurring in the pediatric population. Diagnosis is often delayed as clinical presentation manifests with vague anterior knee pain, sometimes with mild local signs of inflammation but frequently without any local signs at all. While falls on the knee can explain mild knee pain, erythema, swelling and persistent peripatellar pain s...
