Current UK NICE guidelines on the prevention of thromboembolism state that all patients undergoing elective Hip or Knee Replacement surgery should be offered combined mechanical and pharmacological VTE prophylaxis. The original audit was performed between October 1999 and January 2009, totaling 7,532 patients. Updated to the full 10 years, a total of 8,140 patients underwent hip or knee replacement surgery (revision and primary) in our unit. Using a targeted thromboprophylaxis policy 83% of patients received mechanical A-V foot pumps only until mobile. High risk patients (12%) received in addition LMWH or fondaparinux, with only very high risk patients continuing on chemical prophylaxis post-discharge. All data are collected and stored on our own joint registry database with patients being assessed pre-operatively to determine their level of VTE risk.Background
Methods
To study the efficacy of Hydroxyapatite (HAC) Ceramic Coated hip arthroplasty. Is it suitable for the younger patient? This series of 2390 primary HAC hip arthroplasties has been studied for up to 21 years. (569 hips over 10 years including 98 hips over 15 years) Patients are assessed by Harris Hip Score and plain X-ray. The prosthesis consists of a fully coated stem and a fully coated acetabulum. A ceramic head articulates with an acetabular liner which is either plastic (UHMW polythene) or ceramic. No cement is used. HA coated implants are physiologically fixed to cancellous bone by a process of osseointegration. Other uncemented implants are pathologically fixed by fibrous scar tissue. These two methods of fixation should be considered separately and not combined as ‘uncemented’.Aim
