Summary

The purpose of this study was to evaluate SANE scores between males and females at the time of their first Quality Movement Assessment (QMA) at 6 months post anterior cruciate ligament reconstruction (ACLR).

Methods

This retrospective study analyzed SANE scores of male and female patients undergoing QMA 6 months and 9 months postoperatively from ACLR. Patient SANE scores were analyzed across leg dominance and sex.

Results

114 patients completed a 6-month post-operative QMA visit. 61.4% (70) were female, age range between 13-55 years. There was no significant difference in SANE scores between males and females 6 months post reconstruction (79.7+10.9 vs. 79.8+13.2, p=0.94). When comparing SANE scores of females who injured their dominant leg vs. non-dominant leg, no significant difference was found. The same comparison made in males found no significant difference in SANE scores. When comparing the group as a whole, there was no significant difference in SANE scores between those who injured their dominant leg vs. non dominant leg. However, when comparing males and females who injured their dominant leg, females had a significantly higher SANE score compared to their male counterparts (84.8+7.8 vs. 79.41+7.5, p=0.04).

47 patients were analyzed during the second QMA visit at 9 months post-surgery. There was no significant difference in SANE scores between males and females 9 months post ACLR (89.4+7.7 vs. 90.2+6.5, p=0.70). SANE scores significantly increased from 6 to 9 months postoperative for both males (80.9+7.5 vs. 89.4+7.7, p<0.001) and females (79.3+11.6 vs. 90.2+6.5, p<0.001).

Discussion And Conclusion

While previous studies have reported on the differences between males and females regarding psychological readiness of return to sport, we found no clinically significant difference in SANE scores between males and females at 6- & 9-months post ACLR. However, in patients who injured their dominant leg, we found that females had significantly higher SANE scores than males. It should be noted that these results did not meet the MCID criteria for knee-related SANE scores (7 at 6 months post-op). Future studies should evaluate larger populations when analyzing sex differences in patient readiness for RTS. Lastly, both male and female patients demonstrated significant improvements in SANE scores from 6 to 9 months postoperatively, supporting the current evidence that early RTS 6 months postoperative may be contraindicated in this young demographic.

Conclusion

Clinicians should consider leg dominance when evaluating psychological readiness for return to sport.
