AB  - PURPOSE: Using a surgical extension table during total hip arthroplasty (THA) is 
      widely considered state-of-the-art. However, intra-operative leg positioning 
      requires additional time and leg length determination can be challenging. Our 
      study's aim was to compare patient outcomes, particularly leg length precision, 
      following surgery with or without an extension table. METHODS: This retrospective 
      study included data from medical records of 324 patients who underwent THA using 
      the direct anterior approach by one surgeon at a Swiss cantonal hospital 
      (2015-2017). Patients were grouped by table type-standard (T(S)) or extension 
      table (T(E)). Variables analyzed were demographics, operative/anaesthetic 
      conditions, and medical outcomes. The leg length was measured pre- and 
      post-operatively with mediCAD Classic(R). RESULTS: An extension table was used in 
      161 (49.7%) patients. The median operative duration (minutes) was shorter in T(S) 
      (55 (interquartile range (IQR) 48-67) than T(E) (60 (IQR 54-69)) (p = 0.002) and 
      blood loss (ml) was lower (T(S) = 400 (IQR 300-500), T(E) = 500 (IQR 300-600), p 
      = 0.0175). The median post-operative leg length discrepancy (mm) was less in T(S) 
      (T(S) = 1 (IQR 0-3), T(E) = 2 (IQR 0-4), p = 0.0122). All four dislocations 
      occurred in T(E), and 7.4% of patients had complications (T(S) = 7%, T(E) = 7.5%, 
      p = 0.99). CONCLUSION: We found that operating on a standard table during THA 
      resulted in slightly more favourable outcomes. Given the added expenses, human 
      resources, and time associated with an extension table, opting for a standard 
      table remains a sensible choice.
