Risk Factors for High Repair Tension During Rotator Cuff Repair.

Background

Excessively high repair tension, especially tension ≥10 N, can lead to unsuccessful rotator cuff repair.

Purpose/Hypothesis

The purpose of this study was to identify the preoperative risk factors for high repair tension in rotator cuff repair. It was hypothesized was that older age, longer symptom duration, nontraumatic (ie, degenerative) tear onset, progressive fatty degeneration, and larger tear size would be among the risk factors.

Study Design

Cross-sectional study; Level of evidence, 3.

Methods

This retrospective study involved 80 patients (80 shoulders) diagnosed with rotator cuff tears by magnetic resonance imaging between July 2018 and August 2020. Repair tension was measured intraoperatively using a digital tension meter. Risk factors for high repair tension (≥10 N) were evaluated. The

Results

Symptom duration of ≥4 months, nontraumatic tear onset, large/massive tears, mediolateral (ML) tear length of ≥20 mm, and anteroposterior (AP) tear length of ≥18 mm were associated with high odds of repair tension ≥10 N (

Conclusion

The independent risk factors for high repair tension (≥10 N) during rotator cuff repair were nontraumatic tear onset, ML tear length of ≥20 mm, and AP tear length of ≥18 mm. Symptom duration of ≥4 months and large/massive tears were associated with high odds of repair tension ≥10 N, although they were not considered independent risk factors. Prospective cohort studies with larger sample sizes are needed to confirm the clinical value of the risk factors identified in this study.
