BACKGROUND: Patients with postpolio syndrome (PPS) may be afflicted by hip arthritis in either the paralytic or contralateral limb. Total hip arthroplasty (THA) may be considered in these patients. However, short-term and long-term outcomes following THA in PPS patients remain poorly characterized.
METHODS: The PearlDiver MHip administrative database was queried for patients undergoing THA. Patients with a diagnosis of PPS were matched 1:4 with control patients on the basis of age, gender, and comorbidity burden. Incidence of postoperative adverse events and readmission in the 90 days following surgery and occurrence of revision arthroplasty in the five-year postoperative period were assessed between the two cohorts.
RESULTS: In total, 1,519 PPS patients were matched to 6,076 control patients without PPS. After controlling for patient demographics and comorbidities, PPS patients demonstrated higher 90-day odds of urinary tract infection (odds ratio [OR] = 1.34, P = .016), pneumonia (OR = 2.07, P < .001), prosthetic dislocation (OR = 1.63, P = .018), and readmission (OR = 1.49, P = .002). Five years following surgery, 94.7% of the PPS cohort remained revision-free, compared to 96.7% of the control cohort (P = .001).
CONCLUSION: Compared to patients without PPS, patients with PPS demonstrated a higher incidence of urinary tract infection, pneumonia, prosthetic dislocation, and hospital readmission. In addition, five-year incidence of revision arthroplasty was significantly higher among the PPS cohort. In light of these increased risks, special considerations should be made in both preoperative planning and postoperative surveillance of PPS patients undergoing THA.
LEVEL OF EVIDENCE: Level III.
