Purpose:
To use an expected-value decision analysis to determine the optimal treatment decision between repair and biceps tenodesis (BT) for an isolated type II SLAP injury.
Methods:
An expected-value decision analysis with sensitivity analysis was performed to systematically quantify the clinical decision. To determine outcome probabilities, a decision tree was constructed (repair vs BT) and a meta-analysis was conducted. To determine outcome utilities, we evaluated 70 patients with a chief complaint of shoulder pain regarding age, sex, Shoulder Activity Level, and visual analog scale score in terms of potential outcome preferences. Statistical fold-back analysis was performed to determine the optimal treatment. One-way sensitivity analysis determined the effect of changing the reinjury rate on the expected value of BT.
Results:
The overall expected value was 8.66 for BT versus 7.19 for SLAP repair. One-way sensitivity analysis showed that BT was the superior choice if reinjury rates were expected to be lower than 28%. Meta-analysis of 23 studies and 908 patients revealed that the probability of a "well" outcome was significantly greater for BT (87.8%; 95% confidence interval [CI], 74.9%-94.6%; I2 = 0.0%) than for SLAP repair (62.9%; 95% CI, 55.9%-69.3%; I2 = 65.9%; P = .0023). The rate of reinjury was 1.5% for BT (95% CI, 0.05%-33.8%; I2 = 0.0%) and 6.4% for repair (95% CI, 4.2%-9.6%; I2 = 24%), which was not statistically significantly different (P = .411). A total of 50 participants (mean age, 25.4 years [standard deviation, 8.9 years]; 76% male patients; 50% overhead athletes) met the inclusion criteria. Forty-six percent of participants had a high Shoulder Activity Level score.
Conclusions:
Decision analysis showed that BT is preferred over repair for an isolated type II SLAP tear based on greater expected value of BT versus repair. Meta-analysis showed more frequent favorable outcomes with BT. Surgeons can use this information to tailor discussions with patients.
