This systematic review and meta-analysis evaluated the statistical robustness of nonsignificant outcomes from randomized controlled trials comparing biceps tenotomy and tenodesis during shoulder arthroscopy. Analyzing seven studies with 622 patients, the mean reverse continuous fragility index (rCFI) was 17.7, indicating moderate robustness. Notably, 57.14% of studies showed significant outcomes favoring tenodesis over tenotomy.
Key findings
- The mean rCFI of primary outcomes was 17.7 (SD, 8.6; range, 4-26).
- 57.14% of studies reported a significant outcome favoring tenodesis over tenotomy.
- The total loss to follow-up across studies was 55, averaging 7.8 per study.
- The mean reverse fragility quotient was 0.227 (SD, 0.104).
Why it matters
Understanding the statistical robustness of treatment outcomes in shoulder arthroscopy is crucial for clinicians when making informed decisions about biceps tenotomy versus tenodesis. This analysis provides insights into the reliability of existing evidence.
