Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Cognitive biases are systematic patterns of deviation from norm or rationality in judgment, while heuristics are tactics, or mental shortcuts to aid in the decision-making process.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Less is known about which specific cognitive biases and/or heuristics that are in play when patients with knee osteoarthritis form their treatment expectations and evaluate their health following an intervention.
This study aims to understand if certain cognitive biases and heuristics are present in patients with knee (OA) being treated with open label intra-articular placebo injections.
Understanding which cognitive biases and/or heuristics that are in play when these patients evaluate their health outcome following open label placebo, allows future treatment context to be designed in a way that actively utilises these cognitive biases and/or heuristics to obtain a greater magnitude of response.
A global predefined questionnaire, evaluating the presence and strength of the affect heuristic, is sent to all participants from the study "Reinforcement of Treatment Response in Knee Osteoarthritis: A Randomised Trial" (Clinical trial.gov registration: NCT05225480). In addition investigators will invite responders and non-responders respectively from the same study to group interviews in order to produce a structured conceptualisation map; the group content mapping method.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Responders
Participants from the trial "Reinforcement of Treatment Response in Knee Osteoarthritis: A Randomised Trial" will be defined as responders if they belong to the upper quartile of the change to the pain Visual Analogue Scale (VAS) (those who had the greatest positive changes)
Saline
Open label intra-articular injection of isotonic saline.
Non-responders
Participants from the trial "Reinforcement of Treatment Response in Knee Osteoarthritis: A Randomised Trial" will be defined as non-responders if they belong to the lower quartile of the change to the pain Visual Analogue Scale (VAS) (those who had the smallest change).
Saline
