Abstract

Sixtythree juvenile patients range 8–16 years with an OCD of the knee or the talus underwent arthroscopy after MRI In 54/9 out of 63 cases 15/3 T MR scanners were used The OCD stage was classified according the staging criteria of Dipaola et al Arthroscopic findings were compared with MRI reports in each patientFrom the 63 juvenile patients MRI/arthroscopy revealed a stage I OCD in 4/19 patients stage II in 31/22 patients stage III in 22/9 patients and stage IV in 6/6 patients No osteochondral pathology was evident in arthroscopy in seven out of 63 patients The overall accuracy of preoperative MRI in staging an OCD lesion of the knee or the talus was 413  In 33 out of 63 patients 524  arthroscopy revealed a lower OCD stage than in the preoperative MRI grading and in four out of 63 cases 64  the intraoperative arthroscopic grading was worse than in preoperative MRI prior to surgery The utilization of the 3 T MRI provided a correct diagnosis with 444 Even with today’s modern MRI scanners it is not possible to predict an accurate OCD stage in children The children’s orthopaedist should not solely rely on the MRI when it comes to the decision to further conservative or surgical treatment of a juvenile OCD but rather should take surgical therapy in consideration within persisting symptoms despite a low OCD stage provided by MRI
