Translated title:
Study of the patellofemoral joint of the elite athlete
Patellar instability averts the individual from sports’ participation and discourages efforts for a higher level of athletic performance. Acute patellar dislocation (PD) in younger patients is associated with increased number and severity of underlying abnormal anatomic factors of the patellofemoral joint (PFJ), which predispose to patellar instability. In these patients the amount of load to dislocate the patella is significantly lower compared with the general asymptomatic population with more or less normal PFJ anatomy. On the other hand, PD is extremely rare in elite athletes, in spite of repetitive high stresses imposed on the PFJ over long periods of time. This study hypothesized, that elite athletes present unique PFJ anatomy, which might be different from the PFJ anatomy of the average population, in favor of patellar stability in elite athletes. PFJ indices, such as the Insall-Salvati ratio, the sulcus angle, the sulcus depth, the lateral trochlear inclination, the trochlear facet asymmetry and the TT-TG distance of elite athletes differed significantly between elite athletes and the general healthy population, indicating increased stability of the PFJ of elite athletes. No difference was found for other indices of patellar instability, such as the patellar tilt, the congruence angle and the patellotrochlear index. This study supports that the increased PFJ stability of elite athletes is, at least in some part, attributed to better PFJ characteristics compared to the general population. Nevertheless, it should always be kept in mind, that except of perfect PFJ anatomy, neuromuscular coordination between the core and the limbs, along with the determination of the individual to be the best are required to achieve elite athletic performance.
