6 Recommendations for further research
6.1 The Committee recommended that research should be carried out to determine the relationship between activity and prosthesis failure.
6.2 The Committee recommended the collection of data on prosthesis failure or on the prevalence of people living with a failed hip but for whom revision surgery is not suitable or who choose not to have revision surgery. The Committee further recommended that nomenclature for hip replacement failure needs to be established to allow demarcation of prosthesis-dependent and prosthesis-independent hip replacement failure. Furthermore, patient reported outcome measures collected as part of the National Joint Registry should allow for reporting of hip replacement failure in people who cannot or choose not to have revision surgery.
