I have searched MEDLINE and CINAHL for information about the use of CPM machines after ACL reconstruction, and so far have only found one randomised controlled trial regarding their use which has more than 50 subjects per group (by Witherow et al). Does anyone know of any other good published or unpublished trials into the use of CPM after ACL reconstruction? Any other useful info please?
