Abstract

Total knee replacements (TKR) are often deemed successful when patients recover and maintain their functionality both in the short and long term. The other main indicator for success is the revision rate following TKR. This study analyses the long term results of navigated TKR based on patient related outcomes in terms of patient satisfaction, Oxford Knee Score (OKS) and also knee revision rates.
The retrospective data of all patients who underwent navigated Columbus TKR from the author’s institution from 2005 to 2011 was analysed and compared to the national database. The overall cohort size was 1679 with a mean age of 68.81yrs (sd 8.46). The OKS, satisfaction scores, complication and revision rates were compiled and evaluated up to ten years post-operatively. Patient reported outcomes were recorded six weeks, one, two, five and ten years post-operatively.
The results from the OKS and satisfaction scores demonstrated marked improvement throughout recovery to the ten year time point. The OKS had a mean improvement of 16.6 from the pre-operative score at the 10 year time point and the satisfaction scores improved at each follow-up and remained high at the 10 year time point. A total of 61 complications and 36 revisions recorded, with infection being the major cause for revisions.
This survey has identified and established that the majority of patients undergoing knee arthoplasty using the Columbus total knee system and computer navigation function reasonably well in the long term and the revision and complication rates in this hospital are compare well with national levels..
