Abstract
Background: Exertional compartment syndrome (ECS) is an underdiagnosed cause of lower extremity pain among athletes. The condition can be managed operatively by fasciotomy to relieve excess compartment pressure. However, symptom recurrence rates after fasciotomy are considerable, ranging from 3% to 17%. Hypothesis: Leg paresthesia and its distribution during ECS episodes would be a significant predictor of outcomes after fasciotomy. Study Design: Retrospective cohort study. Level of Evidence: Level 4. Methods: We conducted a retrospective chart review of patients who underwent fasciotomy for ECS at our center from 2010 to 2020 (institutional review board no. 21-00107). We measured postoperative outcomes including pain frequency and severity, Tegner activity level, and return to sport. Significant predictors of outcomes were identified using multivariable linear and logistic regression. P values <0.05 were considered significant. Results: A total of 78 legs (from 42 male and 36 female participants) were included in the study with average follow-up of 52 months (range, 3-126 months); 33 participants (42.3%) presented with paresthesia. Paresthesia was an independent predictor of worse outcomes, including more severe pain at rest ( P = 0.05) and with daily activity ( P = 0.04), reduced postoperative improvement in Tegner scores ( P = 0.04), and lower odds of return to sport ( P = 0.05). Those with paresthesia symptoms in the tibial nerve distribution had worse outcomes than those without paresthesia in terms of preoperative-to-present improvement in pain frequency ( P < 0.01), pain severity at rest ( P < 0.01) and with daily activity ( P = 0.04), and return to sport ( P = 0.04). Conclusion: ECS patients who present with paresthesia have worse pain and activity outcomes after first-time fasciotomy, but prognosis is worst among those with tibial nerve paresthesia. Clinical Relevance: Paresthesia among ECS patients is broadly predictive of more severe recurrent leg pain, reduced activity level, and decreased odds of return to sport after fasciotomy.
