Knee range of motion. This will be assessed by a photo taken of the patient's leg in supine, with skin markers placed on the lateral malleolus and greater trochanter, with the knee in maximum flexion and extension. A goiniometer will be used to measure the knee position in the photo using the markers as reference points.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects are recruited when they attend a pre-operative education session. Patients are screened by a research officer, and eligible patients are given a subject information sheet and consent form as approved by the Sydney South West Area Health Service human Research Ethics Committee. Consenting patients then underwent initial assessment. Following surgery, patients are assessed by a blinded assessor. Eligible subjects are then allocated into one of the three treatment groups by therapy staff (who are not blinded) by means of consecutively numbered concealed envelopes.
