title: Use of closed suction drain after primary total knee arthroplasty - an overrated practice.
abstract: OBJECTIVE
  The age-old practice of closed suction drain following orthopedic procedures has been challenged since past few decades. Our aim was to assess the effectiveness of closed suction drain after total knee arthroplasty.
  
  
  METHODS
  One hundred twenty patients (135 knees) with primary Total Knee Arthroplasty were divided into a study group (no drain) and a control group (drain used). Inclusion criteria were grade 3 and grade 4 osteoarthritis of the knee. Revision cases and rheumatoid arthritis were excluded. Parameters assessed were pain, pre and post-op Hb, dressing change, early infection, ecchymosis and duration of stay. Results were calculated using Western Ontario and McMaster Universities Osteoarthritis Index and Oxford Knee scoring systems at two weeks, six months and one year.
  
  
  RESULTS
  Mean age was 72.03 ± 6.68 in study group and 71.38 ± 7.02 in control group. Pre and post op Hb was 12.1678 ± 1.3220 (study group), 12.1803 ± 1.2717 (control group) and 9.8373 ± 1.5703 (study group), 9.7918 ± 1.4163 (control group). There was one case of early infection in both groups which was controlled by oral antibiotics. Change of dressing and ecchymosis were more in the study group. Duration of hospital stay was more in the control group p < 0.0006 (statistically significant).
  
  
  CONCLUSIONS
  There is no added advantage of closed suction drain over no drain usage and this practice can safely be brought to a halt.
