A randomised, prospective, study is to be set up to compare the results of 2 different ways of undertaking femoral fixation in ACL reconstruction surgery. One arm of the study will be randomised to have their surgery using a fixed length suspensory loop device for achieving femoral side graft fixation, and the other to have an adjustable suspensory loop used. The study will be carried out in the operating theatres, orthopaedic out-patients department and the physiotherapy department at the Royal Devon and Exeter (RD+E) Hospital.
