This issue sees us highlighting the modern approach for assessing and reconditioning athletes, as they aim to return to the high demands of modern sport following ACL surgical reconstruction.

I have therefore asked the well-respected Sport Scientist at Aspetar, Paul Read PhD, to guest edit this issue. As the lead investigator on the research project on ACL Return to Play study here at Aspetar, he is perfectly placed to take on this challenging topic.

He has done a great job both with this issue, and with his research in general.

I would like to thank all the contributors, but especially Paul, for his generous contribution and effort which makes this possible.
