Background:
Untreated or residual developmental dysplasia of the hip may cause significant morbidity. Periacetabular osteotomy (PAO) allows for surgical reorientation of the acetabulum but requires a significant recovery period. Because of the physical demands of active military service, hip dysplasia or its treatment with PAO may cause a significant impact on the careers of affected personnel.
Purpose:
To measure the impact of symptomatic acetabular dysplasia and its treatment with PAO on the physical readiness of personnel in the United States Armed Forces.
Study Design:
Case series; Level of evidence, 4.
Methods:
Records from an interservice hip-preservation practice were reviewed for all patients who underwent PAO while on active duty from January 2014 through April 2017. Collected information included branch of service, military occupation, preoperative duty restrictions related to the hip, and concomitant surgical procedures. Patients were evaluated for a minimum of 24 months and assessed for their time to return to duty, continued duty restrictions, and referrals to the medical evaluation board.
Results:
Twenty patients (15 female, 5 male) underwent a PAO while on active duty during the period assessed. The mean patient age at surgery was 25.9 years, and the mean follow-up was 3.3 years (range, 2.3-5.4 years). In the 6 months preceding surgery, 94% of the 17 patients with available records were on duty restrictions specific to their hip (14 temporary, 2 permanent). After PAO, 35% of patients (n = 7) returned to full duty and 85% were able to remain on active duty (n = 12) or complete their military service commitments (n = 5) without noted medical disability. Three patients were medically discharged after PAO, with 1 patient referred due to hip pathology.
Conclusion:
Acetabular dysplasia significantly affects physical readiness in affected servicemembers, with 94% requiring duty restrictions. PAO allowed 85% of patients to return to military service, and 1 in 3 were able to return to full duty.
