Opinions differ on the effects of excision of the patella. Good results were reported by Blodgett and Fairchild (1936), by Dobbie and Ryerson (1942) and by Horowitz and Lambert (1946). Indeed Brooke (1937) stated that the function of the knee was better than the normal after removal of the patella, and that the patella was not morphologically an integral part of the quadriceps tendon. These opi...

Objectives: Meniscal ramp lesions describe a specific injury to the meniscocapsular junction at posterior horn of medial meniscus. The are strongly associated with anterior cruciate ligament (ACL) injuries and may affect biomechanical stability knee if left untreated. Despite increasing rates ACL reconstructions performed in adolescents each year, prevalence risk factors for this patient popula...

Stress fractures of the patella occurring in athletes are quite rare and only 23 cases have been introduced in English literatures. Stress fractures of the patella are classified into two types: transverse and longitudinal. They are mostly seen in the distal one-third of the patella on a plain lateral radiograph. We present here a 16-year-old female basketball player with a stress fracture of t...

    Background: Abnormal patellar height is associated with anterior knee pain and several conditions that affect the patellofemoral joint. The aim of this study was to 1) report the incidence of patella alta and patella baja and 2) investigate whether the normal limits of the Insall-Salvati ratio is applicable in adult Middle-Easterners. Methods: A radiographic review of the lateral radiograph...

Abstract Background Whether vastus medialis obliquus atrophy exists in patients with patellofemoral pain syndrome and whether the amount of differs between lateralis muscles remain unknown. Materials From June 2016 to March 2019, 61 were retrospectively included study group, an age-, sex-, body mass index-matched cohort normal knees was randomly selected as control group. All enrolled subjects ...

INTRODUCTION Nail patella syndrome is a rare autosomal dominant hereditary condition, with an incidence of 22 per million in the United Kingdom. The syndrome's most common features include iliac horns, hypoplastic patella and nail dysplasia. CASE PRESENTATION We report the case of a 26-year-old Caucasian man with nail patella syndrome who sustained a fracture of his right hypoplastic patella ...

UNLABELLED The achievement of a well-balanced total knee arthroplasty is necessary for long-term success. We hypothesize that the dislocation of the patella during surgery affects the distribution of loads in the medial and lateral compartments. Intraoperative load sensors were used to record medial and lateral compartment loads in 56 well-balanced TKAs. Loads were recorded in full extension, r...

A cross-sectional analysis was performed to evaluate associations of polymorphisms in the vitamin D receptor (VDR), delta-aminolevulinic acid dehydratase (ALAD), and endothelial nitric oxide synthase (eNOS) genes with patella lead concentrations in 652 lead workers in the Republic of Korea. There was a wide range of patella lead (from below detection limit to 946 microg Pb/g bone mineral), with...

65 RADIOLOGIC TECHNOLOGY September/October 2006, Vol. 78/No. 1 Knee pain is a common reason for patient visits to a physician office. Cluette suggests common causes of knee pain, including arthritis, ligament injuries, cartilage injuries, meniscal tears, patellar tendonitis, chondromalacia patella, Bakers cyst, bursitis, Osgood-Schlatter disease, osteochondritis dissecans and gout. Certainly th...
