3 Committee considerations
The evidence
3.1 NICE did a rapid review of the published literature on the efficacy and safety of this procedure. This comprised a comprehensive literature search and detailed review of the evidence from 7 sources, which was discussed by the committee. The evidence included 3 randomised controlled trials, 2 non-randomised comparative studies and 1 case series. The committee also considered safety data from 3 implant summary reports for the Profemur L Modular Stem, Profemur L Classic Stem and Procotyl L Cup, provided by the National Joint Registry. It is presented in the summary of key evidence section in the interventional procedures overview. Other relevant literature is in the appendix of the overview.
3.2 The professional experts and the committee considered the key efficacy outcomes to be: functional outcomes, quality of life and other patient-reported outcomes using validated measures.
3.3 The professional experts and the committee considered the key safety outcomes to be: pain, bleeding, infection, fracture and dislocation.
3.4 Patient commentary was sought but none was received.
Committee comments
3.5 The committee was informed that, for this procedure:
suitable training and mentoring is needed for the first few cases
templating and imaging intensifier should be used during the learning curve of the surgeon
different implants can be used and the safety profiles of different implants may be different.
3.6 The committee noted that this procedure appears to have short-term benefits, including early mobilisation and a relatively short hospital stay.
