Background and Goal of Study: 20% (1) of patients are Anemic before elective limb Arthroplasty. Pre-operative Anemia is associated with increased morbidity, mortality, Length of stay, functional recovery, exposure to blood transfusion and quality of life.
Our goal was to identify the incidence of Anemia in elective TKR patients and their effect on LOS, blood transfusion and AKI at Scarborough Hospital.
Materials and methods: 129 consecutive patients having elective TKR at Scarborough Hospital were included in the study. All the results were analyzed using Word Excel.
Results and discussion: 

Parameter	Variable	Number and percentage	Length of stay in hours
Age	< 70 years	61 ; 47 percent	62
 	> 70 years	69 ; 53 percent	95
Hemoglobin	< 12 g/dl	10 ; 7.75 percent	93
 	> 12 g/dl	119 ; 92.25 percent	72
Blood Transfusion	Yes	5 ; 3.8 percent	125
 	No	124 ; 96.2 percent	73
Acute Kidney injury with transfusion	Yes	2/5 ; 40 percent	125
Acute Kidney injury without transfusion	Yes	15/124 ; 12 percent	93
[Results]


Conclusion(s): Preoperative Anemia, elderly, blood transfusion and AKI prolong the LOS following elective TKR.
