    IntroductionTo compare the efficacy and safety of modified Robert Jones bandage (MRJB) and non-compressive dressing (NCD) on reducing invisible blood loss (IBL) after total knee arthroplasty (TKA).Materials And MethodsEighty patients who underwent unilateral TKA were randomly assigned into two groups: MRJB and NCD groups. Pre- and post-operative hematocrit levels, amount of drained blood and transfused blood were measured and calculated into IBL. Pain score, amount of morphine usage, range of motion (ROM) at discharge, blood transfusion rate, and complications were also recorded and compared between both groups.ResultsThere was no significant difference in the mean IBL between MRJB (221.2 ± 233.3 ml) and NCD groups (158.5 ± 186.7 ml) (p = 0.219). Post-operative pain score at rest and during ambulation, amount of morphine usage, ROM at discharge, blood transfusion rate, and complications were also similar between two groups.ConclusionsThis study cannot determine the benefit of MRJB over NCD. The use of MRJB may not be necessary after primary TKA.
