Biceps tenotomy versus soft-tissue tenodesis in females aged 60 years and older with rotator cuff tears.

Abstract Background Recently, to treat the long head of the biceps tendon lesions in addition to rotator cuff repair has been recommended. However, the differences in clinical outcomes between biceps tenotomy and tenodesis for middle-aged and elderly females remains unclear. The purpose of this study was to compare the outcomes of biceps tenotomy and soft-tissue tenodesis that were performed concurrently with arthroscopic rotator cuff repair in ≥60-year-old females. Methods Female shoulders that underwent arthroscopic rotator cuff repair in our institute in 2016 were retrospectively reviewed. This study included 66 shoulders with concurrent biceps tenotomy or soft-tissue tenodesis: tenotomy group, 41 shoulders; soft-tissue tenodesis group, 25 shoulders. Clinical scores, biceps pain (visual analogue scale, VAS), Popeye deformity, and biceps strength (%contralateral side) were compared between the two groups. Results The mean age was significantly higher in the tenotomy group than the soft-tissue tenodesis group (72 ± 4 and 68 ± 6 years, respectively; P = 0.002). There were no significant differences in post-operative JOA and UCLA scores between the groups. VAS for biceps pain was significantly higher at postoperative 6 months in the tenotomy group than the soft-tissue tenodesis group (2.9 ± 2.5 and 1.7 ± 1.6, respectively, P = 0.03), though there were no significant differences at postoperative 3, 12, and ≥24 months. Subjective evaluation of Popeye deformity was not significantly different between the groups. Postoperative biceps strength was significantly lower in the tenotomy group than the soft-tissue tenodesis group (89.9% and 102.8%, respectively, P = 0.02). Conclusions Both biceps tenotomy and soft-tissue tenodesis concurrent with rotator cuff repair in ≥60-year-old female patients resulted in good outcomes. Shoulders with soft-tissue tenodesis demonstrated earlier improvement in postoperative biceps pain and better postoperative biceps strength than those with tenotomy. There were no differences in objective and subjective Popeye deformity between tenotomy and soft-tissue tenodesis. The LHB procedures, tenotomy or tenodesis, can be selected depending on surgeons’ preference.
