Digital templating is an accurate method of assessing femoral and acetabular component sizes. This allows surgeons to foresee potential problems and also recognize an intraoperative error when a large discrepancy exists between a trial component and the templated size. Preoperative templating data of pelvic radiographs from 100 consecutive patients receiving uncemented implants were templated with Orthoview software (version 2.0CEN; Meridian Technique Ltd, Southampton, United Kingdom). ⋯ Eighty percent of cups were templated to within 2 mm, and 98%, to within 4 mm, and 62% of head length was accurately template. Seven patients were converted from a templated 132° to a 127° femoral prosthesis neck angle. The mean lower limb length discrepancy was +0.05 mm (SD, 5.1 mm) postoperatively.

Review Meta Analysis
Perioperative administration of selective cyclooxygenase-2 inhibitors for postoperative pain management in patients after total knee arthroplasty.
Total knee arthroplasty (TKA) is associated with considerable postoperative pain. The relative analgesic efficacy and adverse effect profile of perioperative use of selective cyclooxygenase-2 (COX-2) inhibitors for patients undergoing TKA are unclear. This is a systematic review and meta-analysis of all randomized controlled trials evaluating perioperative administration of COX-2 inhibitors for TKA. ⋯ There was no difference in blood loss during the first 24 hours after operation between groups. The efficacy of perioperative administration of selective COX-2 inhibitors to reduce postoperative pain and opioid consumption after TKA is validated. Furthermore, it has important outcome benefits after TKA.
