Patello-femoral joint mechanics and pathology. 2. Chondromalacia patellae.

Two distinct lesions affect the articular cartilage of the patella. Surface degeneration occurs particularly on the odd facet; it is age dependent, often present in youth and it becomes more frequent with increasing age. It probably does not occasion patello-femoral pain in youth, but may predispose to degenerative arthritis in that joint in later years and is regarded as a consequence of habit...

Accuracy of Patellofemoral Kinematics Using Multi-plane 3d Shape Registration as a Precursor to Patellofemoral Joint Contact Mechanics

INTRODUCTION Patellofemoral pain syndrome (PFPS) is a debilitating knee impairment and one of the most common causes of orthopaedic related physician visits each year [1] in the general as well as athletic populations. Despite highly concentrated research efforts, the etiology of the pain is not fully understood. Patellofemoral (PF) pain has been demonstrated to be associated with altered PF jo...

Joint hypermobility in patients with chondromalacia patellae.

The relationship between joint mobility and chondromalacia patellae was reported in a prospective study. A total of 115 patients with chondromalacia patellae were compared with 110 healthy individuals without chondromalacia patellae, matched for age and sex, who served as a control group. The degree of joint mobility was scored on a scale of 0-9. The number of individuals with hypermobile joint...

The patellofemoral joint: from dysplasia to dislocation

Patellofemoral dysplasia is a major predisposing factor for instability of the patellofemoral joint. However, there is no consensus as to whether patellofemoral dysplasia is genetic in origin, caused by imbalanced forces producing maltracking and remodelling of the trochlea during infancy and growth, or due to other unknown and unexplored factors.The biomechanical effects of patellofemoral dysp...
