Total knee arthroplasty (TKA) is one of the most successful orthopaedic procedures performed today. This is due to the substantial pain relief and restoration of function after TKA. As result of its success [15, 21], indications for TKA have included younger and more active patients. Therefore, the number of revision TKAs is also rising with a projected increase of 601 % from 2005 to 2030 . Although the results of primary TKAs are well documented with implant survivorship at 15 years greater than 95 % , the results of revision procedures are less predictable and encouraging with an 82 % survivorship at 12 years. Predominant revision failure modes include infection (46 %), aseptic loosening (19 %) and instability (13 %) .
