OBJECTIVE To present the diagnostic and clinical features of a ganglion cyst located on the posterior cruciate ligament and create awareness amongst clinicians of this uncommon diagnosis. CLINICAL FEATURES A 24-year old woman complaining of intermittent left knee pain brought on by an increase in mileage during her training for a half-marathon. A diagnosis of mild chondromalacia patella and a...

To measure the patellar height the ratio of the articular length of the patella to the height of the lower pole of the articular cartilage above the tibial plateau is measured on a lateral radiography of the knee, flexed beyond 30 degrees. Normal values lie between 0-54 and 1-06. The subluxing patella is at the upper end of the normal range, but, in chondromalacia, the male patellae were lower ...

Background & Aims: Chondromalacia patella is one of the chronic dysfunctions of the patella femoral joint which is the most common anterior knee syndrome especially among the youth. Muscle weakness and proprioception deficit are the subsequent problems of this dysfunction. Thus, the aim of this study was the investigation and comparison of the effects of vibration training and resistive exercis...

Dorsal defect of the patella (DDP) is a well-documented yet infrequently observed osteolytic lesion on the superolateral aspect of the patella, primarily occurring in the second and third decades of life. The plain radiographic appearance of DDP is typically a round radiolucent lesion with a peripheral sclerotic margin. On a magnetic resonance imaging (MRI) fluid-sensitive series, DDP is demons...

A simple procedure of using a Smillie knife to release the lateral patellar retinaculum and the capsule in the unstable patella syndrome is described. The syndrome includes recurrent dislocation, recurrent subluxation and acute dislocation of the patella. Arthroscopy, to exclude any other pathology such as chondromalacia patellae, is performed before proceeding to closed lateral release. The re...

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 pa...

BACKGROUND Patella alta and patella baja are important conditions underlying a predisposition to many joint diseases, including patellar luxation and patellar chondromalacia of the articular cartilage. The frequencies of patella alta and patella baja have not yet been determined. The objectives of this study were to determine the frequency of patella alta and to determine reference values to th...

Six boys with fragmentation of the proximal pole of the patella are reported; the condition was bilateral in one. Four of the six presented with symptoms of Osgood-Schlatter's disease or Larsen-Johansson disease of the same or of the contralateral knee, but they had no symptoms or signs relating to the proximal pole of the patella; one also had features suggesting minimal chondromalacia patella...
