BACKGROUND The various measurements of patellar tilting failed to isolate patellar tilting from the confounding effect of its neighboring bone rotation (femoral and tibial rotation) in people sustaining patellofemoral pain (PFPS). Abnormal motions of the tibia and the femur are believed to have an effect on patellofemoral mechanics and therefore PFPS. The current work is to explore the various ...

The patellofemoral joint, the anterior compartment of knee, undergoes earliest degenerative changes throughout life and joint morphology is great importance in appearance pain knee chondromalacia patella. Chondromalacia patella a progressive disease with change normal structure, formation minor or major defects cartilage itself represents significant socioeconomic problem because it occurs youn...

Dear Sir, I would like to report an interesting case of a two-year old, female, spayed Bengal cat with a lesion similar to osteochondritis dissecans (OCD) of the medial femoral condyle with concurrent distal femoral varus, medial patella luxation and hip dysplasia. The cat was presented with an intermittent, mild left hindlimb lameness, which the owner reported to be associated with an audible ...

Fractures of the patella in children and adolescents are rare injuries with particular characteristics. The aim of this study was an analysis of epidemiology, treatment strategy and outcome of this injury. Between 1992 and 2006 all fractures of the patella in patients with an age 5 16 years were included in a case control study. Besides outcome analysis using the modified HSS knee score, radiol...

INTRODUCTION Fracture of the patella, after harvesting the central third of the patellar tendon for a bone-tendon-bone autograft, is a rare complication. MATERIAL AND METHODS We made 1714 reconstructions of the anterior cruciate ligament of the knee using bone-patellar tendon-bone technique, and 7 patients had fracture of the patella (0.42%). The fracture was immediately recognized in the pat...

Purpose: To compare various values in computed tomography (CT) scanning between patella dislocation patients and health controls, to define the difference between the two groups, and to determine the rate of patellofemoral anatomical deformities in patients, providing relevant evidence for the appropriate treatment. Method: 100 health controls and 100 patients with patella dislocation from 2005...

Patellar issues need to be carefully addressed during any revision TKA and the surgeon often faces the question of what to do with the patella at the time of revision. The choice of treatment is often made by balancing what is technically feasible with the risk of potential complications and takes into account the reason for the revision, the type of implant (i.e., metal-backing or all-polyethy...

Paediatric patella fractures are uncommon, accounting for less than 1% of all paediatric fractures. This case report describes a previously undocumented patella fracture in a child, with a clear mechanism of injury. We present a case of a previously healthy 14-year-old boy who fell directly onto his right knee after coming off his pushbike. He sustained an isolated fracture involving the articu...

BACKGROUND Attempts to relate patellar cartilage involvement to anterior knee pain (AKP) have yielded conflicting results. We determined whether the condition of the cartilage of the patella at the time of knee replacement, as assessed by the OARSI score, correlates with postsurgical AKP. PATIENTS AND METHODS We prospectively studied 100 patients undergoing knee arthroplasty. At surgery, we p...

The diagnosis of sex and age-at-death from the adult human skeleton is very important in the field of physical and forensic anthropology for the identification of a human body. Three studies of the diagnosis of the patella reporting an accuracy of approximately 85% have been published; however there is no study about diagnosis of the age-at-death on the basis of morphology of the patella. The p...
