Receiving a referral letter to see a patient with patellofemoral syndrome causes a feeling of heart-sink in most orthopaedic surgeons. It predicts an unhappy patient, a prolonged clinic appointment, and an unsatisfactory outcome. Especially as a reliable operation is an unlikely management outcome. Orthopaedic surgeons tend to be mechanically minded and see their main task as correcting abnorma...

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...

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...

This is the first reported case of bilateral sleeve fractures of the patellae in a child with crouch gait. A 12-year-old boy with hereditary spastic paraparesis (HSP), who was found to have mid-stance crouch of 20° on previous gait analysis, presented with pain of gradual onset and limited mobility. There was no history of trauma. Three-dimensional gait analysis showed that extensor mechanism f...

JISAKOS Published Online First: [please include Day Month Year] doi:10.1136/jisakos2016-000095 ABSTRACT Management of the patella during primary total knee arthroplasty remains an unanswered question. Internationally, there is significant variation in the approach to resurfacing with some geographic regions resurfacing almost universally, ...

The appearance and shape of sesamoid bones within a tendon or ligament wrapping around a joint are understood to be influenced by both genetic and epigenetic factors. Ostriches (Struthio camelus) possess two sesamoid patellae (kneecaps), one of which (the distal patella) is unique to their lineage, making them a good model for investigating sesamoid tissue development and evolution. Here we use...

Chondromalacia of the patella is frequently encountered in patients with anterior knee pain. Arthroscopic chondroplasty with perforation of subchondral bone remains a popular treatment alternative in spite of the inferior mechanical properties of the fibrocartilaginous tissue that this procedure is designed to promote. We report a case of cystic degeneration of the patella as a previously unrec...

background: chondromalacia patella is the most common cause of mechanical knee pain in young women. q angle and knee alignment are important clinical parameters for biomechanics of the patellofemoral joint. objective: to identify the prevalence of knee malalignment and to find out if there is a correlation between knee mal alignment and q angle with age at onset of disease. methods: all patient...

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...
