PURPOSE AND HYPOTHESIS

This study evaluates the functional and cosmetic results following fixation of the long head of the biceps (LHB) tendon at the antero-medial footprint anchor of a rotator cuff reconstruction, using the "lasso-loop" technique.

METHODS

39 patients with a mean age of 62 years with a rotator cuff tear and associated lesion of the LHB tendon were included in this study. Besides rotator cuff repair in an arthroscopic anchor technique, all patients received additional LHB tenodeses using the lasso-loop technique. Clinical follow-up consisted of the Constant score (CS), LHB score, DASH score, and WORC index. Relevant sub-items, such as elbow flexion strength and cosmesis, were compared to the contralateral arm.

RESULTS

At an average follow-up of 22 months (11-39 months), the CS resulted in an average of 81 points. The biceps-specific LHB score showed a mean value of 89 points. The analysis of the DASH score showed an average of 16.9 points and the analysis of the WORC index showed an average result of 79.7 %. Distalization of the biceps muscle was objectively in three cases (7.7 %) (as observed by the examiner) and subjectively in one of those cases (as noted by the patient). There was a loss in elbow flexion strength compared to the contralateral side; however, this loss was not statistically significant and not associated with clinical apparent re-tear or insufficiency of the tenodesis.

DISCUSSION

The arthroscopic lasso-loop tenodesis of the LHB tendon is a time and cost-efficient technique. No additional anchor is needed when included in the rotator cuff repair. Functional and cosmetical results as well as results from the biceps-specific LHB score were good to excellent. The loss in elbow flexion strength is most likely associated with concomitant rotator cuff lesion.

CONCLUSION

The lasso-loop fixation technique of the LHB tendon using the antero-medial footprint anchor in rotator cuff tears is a reliable and cost-efficient procedure.
