I have to agree with physio fix me, I'm going to assume your a forth year otago grad? You have more ability to research than anyone else here, the university has a huge range of journals - far more than any of us have. So just check that you adequately know how to research through the univerity website.
You can email the tutors at the school - Martin knows his stuff or paul. Get our your brukner and kahn (physiobob - this is the prescribed text for otago students). Whats in your prescribed readings from musculo? Go find that book and see if any ACL there and look at your lectures for the referances given, remember who gave you the knee lecture in your musculo lecture and send them an email re: referances for you to look up.

That said if someone is going for surgery - then the knee becomes weaker immediately following that surgery, so a rule that i follow is get that knee as strong and as stable as possible before the surgery so the post op will be easier. Don't let them play sport as they will injur further, and work on safe strengthening in the gym to strengthen pre op - working with their level of pain.

Most ACL's are traumatic and thus hard to prevent, but that said there are things to think about. With sport ensure the biomechanics are correct from the ankle so that the knee isn't under any undue tibial torsion - this will of course affect the proprioreception of the knee and make it more likely to be injured. It's harder to protect a joint if you don't have adequate proprioreception. Exercises such as one leg squats with a swiss ball are brilliant as they encourage propriorecption while working the stability of the knee.

Also think about the attachment of the ACL - from ant tib to post femur hense limiting ant translation of the tibia in open chain and post translation of femur in closed chain. So when giving exercises avoid open chain with weights as the quadriceps will cause anterior translation of the tibia - good to think about post surgery to not pull on the repair too much.

is this your community placement assignment? Don't sweat it, it's hard to please anyone at the physio school. I remember having 130 articles that I read and referanced and then my feedback said I didn't research adequately.
