Operative Efficiency in Military Total Joint Arthroplasty Is Superior at an External Resource Sharing Agreement Facility as Compared to a Military Treatment Facility.

Introduction: Surgeries within the Military Health System (MHS) are often performed by military physicians at External Resource Sharing Agreement (ERSA) hospitals to offload the operative demand at Military Treatment Facilities (MTFs). These agreements allow physicians flexibility in selecting where to treat military service members and other TRICARE beneficiaries. However, there is a paucity of military orthopedic literature comparing ERSA hospitals and MTFs.
