Resumo
Objective: The aim of this study, with cadavers, is to evaluate the relationship between the width and length of the lateral patellofemoral ligament (LPFL) and the size of the lateral patellar articular facet (LPAF). Patellofemoral instability is closely re ate to patellar morphology and the lateral retinacular layers. Studies evidence that the wider the lateral patellar facet and the more strained the lateral retinaculum, the greater the tendency for development of pathology in the patellofemoral joint. Methods: 20 knees were dissected in 20 cadavers. The parts were identified according to gender, age, dissected side, length and width of LPFL and width of LPAF In order to carry out the statistical analysis we adopted the significance level of 5% (0.050) and also used Spearman's Coefficient of Rank Correlation. Results: The LPFL presented a mean width of 16.05 millimeters (standard deviation 2.48) and 42.10 millimeters of length (standard deviation 8.84). The width of the LPAF varied from 23 to 37 millimeters (mean 28.1). It was observed that the relationship between the LPAF and LPFL widths is not statistically significant (p=0.271), whereas the relationship between the LPAF width and the LPFL length is statistically significant (p=0.009). Conclusion: The shorter the LPFL the greater the width of the LPAF.
