Abstract
Background: Osteoarthritis (OA) of knee is a degenerative disorder characterized by the softening, ulceration and focal loss of articular cartilage, sclerosis of the subchondral bone, marginal osteophyte formation and a range of morphological and biochemical changes in the synovium & capsule of the knee joint. Total knee arthroplasty (TKA)has been the treatment of choice for advanced osteoarthritis of knee. TKA is associated with significant post-operative pain. The aim of this study is an evaluation of inflammatory markers (ESR, CRP, INR, TLC) following TKA with use of tourniquet in the perioperative period.Methods: Sample size (n=30) was taken A standard automatic pneumatic tourniquet was used during the surgery. Data on demographics, duration of surgery, Erythrocyte sedimentation rate (ESR), C-Reactive Protein (CRP), Total leukocyte count (TLC), Coagulation profile (INR) and limb circumference were analysed. P-values < 0.05 are considered to be statistically significant. The entire data was statistically analysed using Statistical Package for Social Sciences (SPSS version 21.0, IBM Corporation, USA).Results: The distribution of mean 6-hr post-op and 48-hr post-op ESR is significantly higher compared to mean pre-op ESR (P-value0.05) as well as the preoperative versus 48th hour. The mean% change at 48-hr post-op compared to pre-op in TLC is 96.24% with p value
