This study, titled "Mixed-Methods Evaluation of Short-, Medium-, and Long-Term Outcomes Following Hip Treatment," aims to assess the long-term effectiveness of treatments for pediatric hip conditions, including hip dysplasia, Legg-Calve-Perthes disease, SCFE, and avascular necrosis.
Conducted at Mayo Clinic, the study combines retrospective chart reviews and prospective follow-up to gather data on clinical outcomes, radiographic measures, and patient-reported outcomes (PROs) like functional status, pain, and quality of life.
The retrospective component analyzes records from 1975 to 2024, while the prospective component includes follow-up surveys using validated PRO measures (e.g., HOOS, SF-12, VAS). This study seeks to identify recurrence rates and complications associated with hip treatments, providing insights to improve future care standards for pediatric hip conditions. Data will be securely stored, with confidentiality maintained throughout.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Pediatric patients with hip conditions | Medical records and radiographs of patients who were treated for hip conditions at Mayo Clinic from 1975 to 2022 will be included in a retrospective chart review. Radiographic evaluations will include measurements of the neck-shaft angle, acetabular index, migration index, and other commonly used metrics. The prospective follow-up will include a subset of patients from the retrospective review, who will be complete long-term follow-up surveys. |
