Trends of C-reactive protein and erythrocytes sedimentation rate following total hip and knee arthroplasties and hemiarthroplasty in Western Rajasthan: A prospective study

Introduction: Primary diagnosis of infection can be made by serological inflammatory markers like erythrocytes sedimentation rate (ESR) and C-reactive protein (CRP). This study was planned to determine this normal temporal distribution of ESR and CRP in arthroplasty and hemiarthroplasty in Western Rajasthan. Materials and Methods: This Hospital based Observational Analytical study was conducted in Tertiary care facility, Jodhpur from January 2022 to October 2022. The study population was patients undergoing Total Knee Arthroplasty (TKA) & Total Hip Replacement (THR) and Hemi Arthroplasty (HRA) operation with no history of inflammation, infection, chronic disease, and any autoimmune disease like rheumatoid arthritis. We have enrolled 52 uncomplicated cases. ESR and CRP was analysed over the time. Results: The mean ESR and CRP value is maximum at day 3 in all three groups. The mean ESR value is highest in the THR group, and lowest in the Unilateral TKR group. Values of ESR continue to remain elevated at four weeks.
