Fixed bearing implant design and cemented fixation were both associated with increased AL risk, whereas robotic-assisted surgery was associated with decreased risk. The overall incidence of AL following primary UKA is primarily driven by tibial component loosening and there is a temporal decline in rates. The use of mobile bearing, uncemented implants inserted with robotic assisted surgery may reduce the risk of AL.

The GIRFT report (2012) sought to address the need for sustainable orthopaedic treatment delivered through regional "networks"; the aim being improved care, decreased cost and reduced revision rate. The aims of this study were to record the number and complexity of revision total knee replacements within a regional network using a validated classification over a two-year period and audit this against National Joint Registry (NJR) records. A region-wide network model where revision TKR cases are assessed locally using the Revision Knee Complexity Classification (RKCC) and local multi-disciplinary team (MDT) was introduced. Data was collected from 8 revision centres over a two-year period using the RKCC. The case volume was audited against the NJR records. In year 1 (01/01/2018-31/12/2018) 237 RKCC forms were collected from eight centres. 46% of R2s and 63% of R3s were carried out at the higher volume centre. 211K2 forms were received by the NJR. In year 2 (01/01/2019-31/12/2019) 252 RKCC forms were collected. 46% of R2s and 64% of R3s were carried out at the higher volume centre. 267K2 forms were received by the NJR. This is the first published set of revision k
