Key takeaways:
- Results showed volumetric scores may provide a more comprehensive rotator cuff evaluation vs. Goutallier scores.
- Goutallier scores had high correlation with volumetric scores in evaluation of the supraspinatus.
WASHINGTON — Results presented here showed that volumetric scores may provide a more comprehensive evaluation of the entire rotator cuff unit than Goutallier scores.
“Although considered the gold standard in evaluation of rotator cuff pathology, the Goutallier scores had a negligible correlation with preoperative functional disability,” Mikalyn T. DeFoor, MD, said in her presentation at the American Orthopaedic Society for Sports Medicine Annual Meeting. “Yet, on the contrary, there were several volumetric scores that more strongly correlated with preoperative functional disability, which suggests that our novel 3D MRI-based volumetric assessment may provide a more comprehensive evaluation of the entirety of the rotator cuff unit.”
DeFoor and colleagues identified 82 patients (average age, 55 years; 33% women) who underwent arthroscopic rotator cuff repair and collected data on patients’ Goutallier scores and volumetric scores, as well as preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) physical function and pain interference scores. Volumetric scores incorporated muscle size score, relative contribution score and fat infiltration score.
“The purpose of our study was to describe the correlation between Goutallier and our volumetric scores in evaluation of the supraspinatus, as well as to characterize the overall health of the rotator cuff unit through volumetric analysis, with the overall goal of comparing Goutallier scores to our volumetric scores in their ability to predict preoperative functional disability,” DeFoor said.
Results showed that Goutallier scores had a negligible correlation with preoperative functional disability, defined by PROMIS physical function and pain interference scores, according to DeFoor. However, DeFoor said several volumetric scores were moderate predictors of preoperative functional disability.
In addition, she noted a moderate/strong correlation with fat infiltration and a strong negative correlation with both muscle size and relative volume contribution between Goutallier scores and volumetric scores in the evaluation of the supraspinatus.
“Again, when looking at just the supraspinatus, the relative volume contribution score was the strongest correlation with the Goutallier scores,” DeFoor said.
