Name	Time	Method
Quadriceps weakness and mobility day 1 post operatively. <br><br>This is assessed by the physiotherapist who visit the patient's everyday, specifically on day 1 post operative.<br><br>Quads weakness is assessed from a grade of 1-5, where 1 has not even a flicker of muscle movement through to 5 where there is normal power and movement against resistance and gravity.<br><br>Mobility will be assessed as to whether the patient can complete exercises provided by the physiotherapist in bed, then progress onto the transfer from bed to standing, and finally mobilization with aid of a forearm support frame/4 wheel walker/Hopper frame.[Day 1 post op]

Secondary Outcome Measures

Name	Time	Method
Pain scores - mild, moderate or severe. These will be recorded by the Acute Pain Service who will review the patient day 1 post op.[From day 1 post op until discharge];Complications - these will be recorded in the patient's charts[From day 1 post op until discharge];Length of stay - how many days the patient is required to stay in hospital from day 1 post op till discharge.[From day 1 post op until discharge]
