If you're at uni then you should get access to the books through your library so you can try before you buy - and always be mindful of your recommended reading because they probably form the bulk of your lectures

It can get a bit awkward because different lecturers might prefer different texts - then when you go on outpatients the department might use something else

To cover virtually all bases for sports injury i'd say Brukner and Khan is a must along with Magee's Orthopaedic Physical Assessment then perhaps Shacklocks Clinical Neurodynamics

Those type of books do cost a lot of money but they are at a level which will see you well on your way in your career
