Surgery-related characteristics for the research and clinical cohorts. Neuroaxial anaesthesia was more frequently used in the clinical cohort compared with the research cohort for both THA and TKA. The length of surgery was longer in the research cohort than in the clinical cohort. Data are presented for the combined databases and for THA and TKA separately. The completeness in the THA and TKA clinical cohorts for length of surgery was 101,203 (100%) and 27,218 (30%), respectively. NA: not applicable
