To investigate value of T2 color maps in assessment of patellar cartilage injury grading.  

62 patients who underwent knee MR and arthroscopic surgery patients were collected, including 32 males and 30 females, aged 30-51 years, mean 40.7 years. GE Company Signa3.0T MR was used. The scan sequence include: FSE-T1WI, FSE-T2WI, FS-FSE-PDWI and T2mapping. T2mapping images were sent to the GE-ADW 4.3 workstation to generate T2 color maps of patellar cartilage. Arthroscopic patellar cartilage grading standards, to explore T2 color maps value of the patellar cartilage grading injury.

T2 color maps showed a uniform blue color levels in normal patellar cartilage and blue levels of normal cartilage contrast with the gray levels joint effusion, which would be helpful to find cartilage defects. In 62 cases of patellar cartilage, 16 cases were diagnosed as normal patellar cartilage in T2 color maps. I-IV grade injury were 17, 11, 10, 7 cases respectively. 14 cases were confirmed as normal patellar cartilage via arthroscopic surgery ，and I-IV grade injury were 18, 10, 10, 8 cases respectively. T2 color maps and arthroscopy in the diagnosis of patellar cartilage damage of varying degrees of correlation coefficient rs = 0.956, P <0.05; the T2 color maps and arthroscopic evaluation of cartilage damage difference test, p> 0.05, T2 color maps and arthroscopic damage to the evaluation of patellar cartilage grading was no significant difference.  

T2 color maps would be reliable in classification of patellar cartilage damage assessment.

T2 color maps can be used to evaluate different grades of patellar cartilage damage，and providing a reference basis for the clinical diagnosis of cartilage damage.
