POST-OPERATIVE PAIN FOLLOWING JOINT REPLACEMENT SURGERY

Patients overestimate pain following hip and knee replacement. Ninety two patients awaiting hip or knee replacement were asked at their pre-operative assessment to estimate the level of pain they expected following their surgery on a 10cm visual analogue scale. Note was made of their age, gender, previous surgeries, Amsterdam anxiety score as regards the anaesthetic and surgery and an information score relating to their anaesthetic and surgery. Seventy nine patients had pain scores collected on a daily basis post surgery. Mean (std dev) age of the group was 68 (11) years and with a female to male ratio of 1.57. Females were significantly more anxious about the surgery than males (t-test, p The level of pain experienced post-operatively was significantly lower than expected. Mean (std dev) pain score was 5.1 (2.7) on day 1 post op and 3.3 (2.4) on day 6 (t-test, p The majority of patients, whatever their age, gender or level of anxiety over estimate their level of post-operative pain after joint replacement. Studies are needed to assess whether educating patients about pain post surgery will be of benefit, particularly in their early rehabilitation.
