Advice

Should not replace clinical examination and surgical decision-making in determining operative candidates for hip arthroscopy.

Management

  • In patients with higher RAPID Scores (4-5), surgeons should have their preferred tools for managing ALAD grade 3-4 lesions (e.g. microfracture awls, cell-based therapies) listed and available at the time of surgery.

  • Additionally, patients should be preoperatively counseled on preferred high-grade lesion treatment and its potential influence on rehabilitation components, e.g. continuous passive motion (CPM) machines and time course.
