T

he patellofemoral joint (PFJ) is an anatomical area that is most often involved in the pathological process, mainly in people of a young age group. In order to be able to assess pathological changes in the PFS at all stages of patellar tracking from the flexion position to the position of the maximum possible extension of the knee joint in the radiology department 2 of the University clinical hospital 1 (Sechenov University). A method for diagnosing pathology of the patellofemoral joint was developed and put into practice using functional MSCT (fMSCT).

Purpose. To evaluate the possibilities of functional multispiral computed tomography (fMSCT) in the diagnosis of PFJ pathologies.

Materials and methods. A total of 67 patients aged 18 to 59 years with suspected pathology of the PFS, including lateral patellofemoral instability and hyperpression of the lateral facet of the patella, were examined. All patients underwent knee joint examination using fMSCT on an Aquilion ONE 640 tomograph (Canon, Japan).

The results and discussion. When analyzing the results of fMSCT, the following data were obtained: 77.6% of patients (n=52) had patellar lateroposition, 71.6% (n=48) had hyperpression of the lateral facet of varying degrees, 14.9% of patients (n=10) had patellar medialization, high patellar location was noted in 25.3% of patients (n=17). In 47.7% of patients (n=32), degenerative-dystrophic changes in PFJ were visualized. As a result of the analysis of fMSCT data in 67 patients (100%) with clinical signs of PFS pathology in 40% of patients (n=27), orthopedic traumatologists subsequently changed the tactics of surgical treatment – arthroscopic lateral patella release was performed. Thus, functional MSCT of the knee joint allows for a full-fledged examination of patients with suspected PFS pathology and obtaining detailed diagnostic information about the state of anatomical structures of the patellofemoral joint, which is necessary for more accurate planning of surgical intervention.

Conclusion. fMSCT of the knee joint is a new, modern method of radiological diagnostics, which has high diagnostic capabilities in detecting pathologies of the PFJ, including verification of facet hyperpression, lateroposition and medialization of the patella and makes it possible to determine the most optimal patient management tactics, which in turn helps to improve the results of surgical treatment.
