T2 mapping of patellar cartilage after single and first-time traumatic lateral patellar dislocation episode

The purpose of the study was to examine short-term consequences of the single and first-time lateral patellar displacement on patellar cartilage quality in teenagers using T2 mapping. The research showed a principal difference in T2 changes between medial and lateral cartilage facet. The medial part usually suffering first after LPD, the absence of T2 changes for the mild group may indicate completed reparative processes, while the decrease in T2 denotes that the reparation is still ongoing. T2 increase in lateral patellar regardless chondromalacia severity indicates secondary damage.
