Research Ideas from current physiotherapists- knee,hip, shoulder treatment interventions

Hi Physiotherapists,
I am looking to current practicing physios to help guide me to a research question for an assignment. We are interested in researching some sort of intervention around the hip, knee, ankle or shoulder- however are not limited to. So if there is any interventions you know need further evidence, or a niche treatment option etc please drop them down below.
The reason I am asking current physiotherapists is because you will have a better idea around what questions still need to be asked and what mysteries still need solving.

For example: NB.these are not researched ideas just the general idea I am looking for...
Does talocrural mobilisations exercises before games prevent risk of ankle injury in Basketball players?
Is taping really effective in reducing the risk of recurrent ACL injury?
Does greater thoracic spine mobility lead to better outcomes with neck injuries in rugby players?

Thanks in advance

Hi,
I have gone through your post. I think thoracic spine mobility is gives better outcomes with neck injuries in rugby players.
