Return to Sport Rates and Subjective Outcomes Are Similar After Open or Endoscopically Assisted Compartment Release for Chronic Lower-Extremity Exertional Compartment Syndrome

PURPOSE: To retrospectively compare return to sport rates and subjective outcomes of patients who underwent open or endoscopic compartment release for the surgical management of chronic exertional compartment syndrome. METHODS: This was a retrospective review of patients who underwent lower-extremity fasciotomy for chronic exertional compartment syndrome from June 2012 to June 2020. Eligibility included patients 15 to 45 years of age who identified as an athlete and had at least 6 months of follow-up. Fasciotomies for trauma or infection were excluded. One surgeon exclusively performed each type of surgery. Postoperative outcome measures included the Lower Extremity Functional Scale, the Marx Activity Scale, and a return to play survey. RESULTS: In total, 24 patients (13 endoscopically assisted fasciotomies, 11 open fasciotomies) had a mean follow-up of 3.8 ± 2.1 years; 19 patients returned to their sporting activity. No significant difference existed between return to play rates (P = .630) or return to play times (P = .351). There were no significant differences between the groups in the Lower Extremity Functional Scale score, Marx Activity Scale score, Single Assessment Numeric Evaluation score, pain score at rest, and during sporting activity. Overall satisfaction rates were found to be significantly greater in the endoscopically assisted fasciotomy group (P = .041). CONCLUSIONS: In this small sample of heterogenous groups of patients, we found no significant differences in return to sport rates or subjective results after surgery. Patients experienced a high subjective recurrence rate. The endoscopically assisted fasciotomy group reported greater subjective patient satisfaction compared with the open fasciotomy group. LEVEL OF EVIDENCE: Level III, comparative study, retrospective.
