Study summary

This study is an observational study to test and validate a questionnaire and statistical model used to determine patient preferences regarding treatment for any one of 11 musculoskeletal conditions: hip arthritis, knee arthritis, hip labral tears and femoroacetabular impingement (FAI), osteochondritis dissecans, Achilles tendon rupture, patellofemoral dislocation, distal radius fracture, and fractures of the hip, ankle, tibia, and proximal humerus. This study aims to understand how multiple treatment variables, including pain, rehabilitation time, cost, and choice of surgical versus non-surgical intervention, impact patients' decision-making processes and ultimate choice of treatment.

Study arms

  • Experimental
    Decision tool

    A "decision tool" will be provided to participants who currently or previously have had one of the following 12 musculoskeletal conditions: hip arthritis, knee arthritis, ankle arthritis, hip labral tears and femoroacetabular impingement (FAI), osteochondritis dissecans, Achilles tendon rupture, patellofemoral dislocation, distal radius fracture, and fractures of the hip, ankle, tibia, and proximal humerus.

    Other: Decision tool

  • Active comparator
    Standard treatment information

    "Standard treatment information" will be provided to participants who currently or previously have had one of the following 12 musculoskeletal conditions: hip arthritis, knee arthritis, ankle arthritis, hip labral tears and femoroacetabular impingement (FAI), osteochondritis dissecans, Achilles tendon rupture, patellofemoral dislocation, distal radius fracture, and fractures of the hip, ankle, tibia, and proximal humerus.

    Other: Standard treatment information

Interventions

  • OtherDecision tool

    A survey will be created for each condition that reflects the most important aspects of the corresponding treatment process.

  • OtherStandard treatment information

    Participants will receive information pertaining to one of the 12 specified musculoskeletal conditions. This information will reflect information commonly distributed to patients seeking to make a decision concerning treatment for their condition.
