Friday, October 8, 2010, 14:00-14:50Session A14: Complication ManagementComparison of Drain Clamp After Bilateral T.K.A.*Firooz Madadi - Akhtar Hospital - Tehran, Iran*Email: fmedadi@yahoo.comSuction drains provide an easy and feasible method for controlling hemorrhage after total kneearthroplasty. However, there has been no compromise regarding the optimal clamping time forthese drains. We conducted a randomized clinical trial to compare 12-hour drain clamping andcontinuous drainage after total knee arthroplasty in terms of wound complications, blood lossand articular range of motion. In order to eliminate any other factor except duration ofclamping, we chose to compare knees belonging to one single person, as well as restricting thestudy to those knees undergoing surgery due to osteoarthritis. From a total of 100 knees (50patients) studied, the 12-hour clamping method resulted in a significantly smaller amount ofpost-operative blood loss (p
F/U was 6.1 years and average HHS was 78.08±15.7. 26 patients were dead and 17 wereinaccessible. The effects of traditional life-style and daily activity level on implant looseningwere also considered.Findings: Multivariable analysis showed that patient’s sex, surgical technique, surgeon, BMI,use of cement weren’t related to either implant loosening or HHS. We had 25 prosthesisdislocations, which all happened by trauma. Considering revision surgery as the end point, thefollowing 10-year-survivals were calculated; cemented cup 60%, uncemented cup 85% andboth cemented/uncemented stems 80%. Considering radiographic evidence of loosening as theend point, the 10-year-survival of cups was 80% and that of cemented, uncemented stems was60% and 70%.Conclusion: Delay in performance THA resulted in more limping (because of anatomydeterioration and muscles weakness) and lower HH. Scores. Additionally, the survival of ourTHAs were generally shorter thanliterature.Thursday, October 7, 2010, 8:30-9:20Session B2: Knee Arthroplasty in the Indian Sub ContinentAnthropometric Measurements of the Indian Knee for Total KneeArthroplasty*Pankaj Mahindra - Dayanand Medical College and Hospital - Ludhiana, IndiaProf. Mohammad Yamin - Dayanand Medical College and Hospital - Ludhiana, IndiaProf. Rajnish Garg - Dayanand Medical College and Hospital - Ludhiana, IndiaHarpal Singh Selhi - Dayanand Medical College and Hospital - Ludhiana, IndiaShekhar Singla - Dayanand Medical College and Hospital - Ludhiana, India*Email: pmahindra@hotmail.comBackground: There is paucity of data concerning the morphological dimensions of the distalpart of the femur and the proximal part of the tibia in Indian population. The objective of thisstudy was to analyse the exact anatomic data collected from patients undergoing total kneearthroplasty.Methods: Morphologic data from the distal part of the femur and proximal part of the tibia,from 50 knees ,were obtained during total knee Arthroplasty, with a microcalliper. The studyincluded 30 women and 20 men, who had a mean age of 65 years. A characterisation of theaspect ratio (the medial-lateral to anterior-posterior dimensions ) was made for the proximalaspect of the tibia and distal part of the femur.Results: A significant difference was noticed in the dimensions of males and females. Femaleswere found to have smaller dimensions, and the difference was statistically significant. Fromthe morphologic data no significant difference was noted in the aspect ratio of both femur andtibia in males and females, and between larger and smaller knees. A comparison of the bonedimensions from the study data and the dimensions of the femoral component showed averagemedial-lateral overhang of +1.9 mm in women.file:///E|/ISTA2010-Abstracts.htm[12/7/2011 3:15:47 PM]
