Cartilage Injury after Patellar Dislocation Surgery and Evaluation of the Effect of Platelet-Rich Plasma Treatment by Algebraic Reconstruction Techniques Based MRI

The study focused on the application value of Algebraic Reconstruction Techniques (ART) based magnetic resonance imaging (MRI) in the diagnosis of cartilage injury in patients with patellar dislocation, as well as the treatment effect of platelet-rich plasma (PRP). 50 patients with patellar dislocation admitted to the hospital were selected as the research subjects, and they were randomly divided into the experimental group (lateral retinaculum plasty and PRP treatment) and the control group (lateral retinaculum plasty), with 25 cases in each group. The ART-based MRI technology was used to judge the recovery of patients after surgery and analyze the differences in clinical data between the two groups. The results showed that the running speed under ART algorithm was significantly faster than the traditional Joseph algorithm and Siddon algorithm, and the image reconstruction effect was better. The visual analog scale (VAS) scores of preoperative and postoperative pain and the Hospital for Special Surgery (HSS) score in the experimental group were better than those of the control group ( ). In conclusion, the ART-based MRI technology can clearly show cartilage injury and the PRP treatment can effectively relieve postoperative pain, with reliable curative effects and simple operations.
