{"doi":"10.1302/3114-220855","title":"Predictors of Long-Term Pain After Hip Arthroplasty in Patients With Femoral Neck Fractures: A Cohort Study","abstract":"Objectives: To identify factors associated with the development of prolonged pain after hip fracture surgery.Design: Secondary analysis of a randomized controlled trial.Setting: Eighty hospitals in 10 countries.Patients/Participants: One thousand four hundred forty-one hip fracture patients in the HEALTH trial.Interventions: Total hip arthroplasty or hemiarthroplasty.Main Outcome Measures: Moderate-to-severe pain (at least 2 activities on the Western Ontario and McMaster Universities Osteoarthritis questionnaire pain subscale with scores $2) at 12 and 24 months after hip arthroplasty.Results: Of 840 and 726 patients with complete baseline data and outcomes at 1-year and 2-year follow-up, 96 (11.4%) and 80 (11.0%) reported moderate-to-severe pain, respectively.An increased risk of pain at both 1 and 2 years after surgery was associated with reporting moderate-to-severe hip pain before fracture [absolute risk increase (ARI) 15.3%, 95% confidence interval (CI) 6.44%-24.35%;ARI 12.5%, 95% CI 2.85%-22.12%,respectively] and prefracture opioid use (ARI 15.6%, 95% CI 5.41%-25.89%;ARI 21.1%; 95% CI 8.23%-34.02%,respectively).Female sex was associated with an increased risk of persistent pain at 1 year (ARI 6.2%, 95% CI 3.53%-8.84%).A greater risk of persistent pain at 2 years was associated with younger age (#79-year-old; ARI 6.3%; 95% CI 2.67%-9.91%)and higher prefacture functional status (ARI 10.7%; 95% CI 3.80%-17.64%).Conclusions: Among hip fracture patients undergoing arthroplasty, approximately one in 10 will experience moderate-to-severe pain up to 2 years after surgery.Younger age, female sex, higher functioning prefracture, living with hip pain prefracture, and use of prescription opioids were predictive of persistent pain.","journal":"OrthoMedia","year":2022,"id":308291,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9553,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[],"reference_count":37,"raw_metadata":null,"created_at":"2026-07-19T00:33:03.486542Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
