Sugaya MRI classification showed no differences between intact rotator cuff repair, partial-thickness retears
Recently published results showed no significant differences in clinical scores between patients with intact rotator cuff repairs or partial-thickness retears as stratified by the Sugaya MRI classification system at 16 weeks, according to results.
At 16 weeks after arthroscopic supraspinatus repair, researchers evaluated 60 patients using the Oxford Shoulder Score, 11-item version of DASH score, VAS for pain, SF-12 health survey, isokinetic strength and MRI. Patients were classified with the Sugaya MRI rotator cuff classification system as having intact repairs (Sugaya grade 1) and partial-thickness retears (Sugaya grades 2 and 3).
Results showed no significant differences in clinical or strength measures between the groups. Researchers noted the DASH score produced a 97% true-positive rate for predicting partial thickness retears. However, it also incorrectly predicted a retear in 90% of patients whose repair was intact, producing a 90% false-positive rate, according to results. Although up to five variables could enhance the ability to discriminate between groups, researchers noted 87% of the partial-retear group and 36% of the intact-repair group were correctly classified. – by Casey Tingle
