Brief Summary
To establish whether a short duration of tourniquet application (from cement fixation to cement setting)is associated with better patient functional outcomes compared to a long duration of tourniquet application (from surgical incision to cement setting). It is hypothesised that tourniquet application during cement fixation only (approximately of 20-30 min duration) will be associated with less pain and impairment than a longer tourniquet application (\> 45 minutes).

Outcome Measures
Primary Outcomes (2)
Oxford Knee score
Oxford knee score is a disease-specific patient perceived knee pain and function survey. It will be collected at baseline (within 2 months of surgery), and then at 10, 26 and 52 weeks post surgery.
10 weeks post surgery
Donor blood transfusion rate
The use of donor blood transfusion in the intra-operative and acute post-operative (hospitalisation) period will be recorded. Criteria for donor blood transfusion is according to the hospital's restrictive transfusion practices.
Within the acute hospitalisation period (from Day 0 (surgery day), to day of discharge)
Secondary Outcomes (5)
Knee range of motion (ROM)
ROM will be assessed pre-operatively (within 2 months of surgery), on day 4 post surgery, and at 2, 10,26 and 52 weeks post surgery
Quadriceps lag
Lag will be assessed on Day 4 post surgery, and at 2, 10, 26 and 52 weeks post surgery.
timed stair test
Measured at 2, 10,26 and 52 weeks post-surgery
Knee pain
Measured on Day 4 post surgery
Analgesic consumption
Measured over course of acute care (summation of day 0 to day of discharge)
Study Arms (2)
Short duration tourniquet
EXPERIMENTALPatients allocated to this group will have the pneumatic tourniquet applied to the index limb for approximately 20-30 minutes during cement fixation of the prosthesis.
Long duration tourniquet
ACTIVE COMPARATORPatients randomised to this arm will have the tourniquet applied from commencement of surgery and removed just prior to skin closure.
Interventions
Patients randomised to this arm will have the tourniquet applied at the commencement of surgery and removed prior to wound closure.
Patients assigned to this arm will have the tourniquet applied during cement fixation of the prosthesis only (ie removed just prior to wound closure).
Eligibility Criteria
You may qualify if:
- primary, unilateral knee replacement;
- capacity to understand the protocol;
You may not qualify if:
- inability to read English;
- current warfarin therapy (or similar);
- significant PVD, peripheral arterial disease or diabetes rendering tourniquet use undesirable;
- evidence of chronic or recent DVT in index limb;
- thigh circumference \> 100 cm (approximately);
- Jehovah's Witness (ie refusal to receive donor blood)
