Abstract

This study used the assessment of quality in lower limb arthroplasty (AQUILA) checklist to assess the quality of lower limb arthroplasty observational studies. Among 132 studies the mean reporting quality score was 5.4 (SD = 1.2) out of 8 possible points. Most studies adequately reported reasons for revisions (98%) and prosthesis brand and fixation (95%) in sufficient detail. Only 3% of studies adequately reported the number of patients unwilling to participate, 15% stated a clear primary research question or hypothesis, 11% reported a worst-case analysis or competing risk analysis for endpoints, and 42% reported more than 5% of patients were lost to follow-up. There is significant room for improvement in the reporting and methodology of lower limb arthroplasty observational studies. Level of evidence: Level III.
