Popis: Objective: In patellar tendinosis the evidence suggests that degeneration may involve central, medial or lateral portions of the patellar tendon. There are few studies that have attempted to establish the basis of spread of the lesion distally or the occurrence of more extensive degeneration involving the main body of the tendon, distal or proximal to the bone–tendon junctions in symptomatic tendons. Furthermore, previous studies suggest that damage to the mid-part of the tendon would be more likely in older (36+ year olds) and heavier individuals. This study set out to determine the effect of age and weight on the occurrence of mid tendon degeneration. Methods: Magnetic resonance images of 41 knees from 34 patients were analysed using increased thickness to indicate damage. All patients presented with a selection of symptoms associated with this condition. The thickness of the tendon in proximal, middle and distal thirds was measured and the percentage of the tendon damage was calculated. Information concerning: gender; age; weight; height; duration of symptoms; sporting activities and whether there was a history of trauma was recorded from the patients files. Results: The most frequent area to be affected was the proximal third of the patellar tendon, the middle third was involved in 25% of cases. Patients with mid tendon degeneration were not found to be significantly older (36+ year olds) or heavier. Conclusions: It appears that in this sample patellar tendinosis does not increase in occurrence with age/weight but is more common in younger individuals; however this only applies to overuse injuries. Analysis of our demographic data suggested that as an overuse syndrome, patellar tendinosis is predominant in young males, and that trauma is a significant causative factor.
