Abstract
  • Osteoarthritis (OA) is a common chronic disorder with symptoms ranging from mild pain to complete loss of function thereby severely influencing the patient's quality of life. Although most patients initially benefit from conservative measures, a large number will eventually require surgical intervention, most commonly in the form of a total knee arthroplasty (TKA). Over 90,000 TKAs are performed annually in the United Kingdom. TKA may be performed either using conventional instrumentation or with the aid of computers, also known as navigated TKA. One disadvantage of using navigation is the increase in total operation time associated with this system. BBraun Aesculap AG (Tuttlingen, Germany) who manufactures the OrthoPilot TKA navigation system has recently introduced a new software, TKA Smart v1.0, that has a simplified registration process and is intended to be more user-friendly when compared to the previous software versions such as TKA 4.3. This, in theory, should result in a shorter operation time. A randomised controlled trial involving 220 patients is currently being conducted at the Golden Jubilee National Hospital to validate the TKA smart v1.0 software and to investigate the reduction in total operation and registration time. This thesis aims to report the preliminary analysis of the trial. The analysis involves 63 patients (34 females) with an average age of 69.2 years. 34 patients were randomised to TKA 4.3 software. The preliminary results show that despite the reduction in the number of steps during the registration process, the clinical, functional and radiological outcomes for the TKA Smart v1.0 software are comparable to the older version TKA 4.3. Furthermore, no statistical or clinical significance was present in the total operation time between the two software despite a statistically (but not clinically) significant reduction in registration time between TKA Smart v1.0 software and TKA 4.3 software.
