The ceramic on ceramic strategy without femoral revision can be considered according to thisstudy. Accurate informations on the taper details are required, as well as carefull peroperativeinspection to exclude damaged stems .The dislocation risk is significant when the previousfemoral implantation is suboptimal.Thursday, October 7, 2010, 11:00-11:20Session B4: Ethnic and Gender Issues in TKR.Complications After Total Knee Arthroplasty With Anterior-PosteriorGlide Low Contact Stress Mobile-BearingPurposeBo-Hyun Hwang - Yonsei University - Seoul, KoreaWoo-Suk Lee - Yonsei University - Seoul, KoreaKwan-Kyu Park - Yonsei University - Seoul, KoreaIck-Hwan Yang - Yonsei University Gangnam Severance Hospital - Seoul, Korea*Chang-Dong Han - Yonsei University College of Medicine - Seoul, Korea*Email: cdhan@yuhs.acThe purpose of this study was to evaluate the complications related to the prosthesis design inpatients managed with cemented total knee arthroplasty (TKA) with the anterior-posterior glide(APG) mobile bearing prosthesis.Materials and MethodsOne hundred eighty three total knee arthroplasties were performed using APG Low ContactStress mobile bearing prosthesis (Depuy, Warsaw, IN) on 146 patients with an average of 8.4years follow-up (range, 7 to 10 years). Patients were evaluated clinically and radiologicallyaccording to the American Knee Society clinical scoring system. The anteroposteriortranslation, anterior soft tissue impingements, and complications were assessed at the follow-upperiods.ResultsNo knee had loosening and measurable polyethylene wear on radiographs. There were latedislocations of bearing in 2 knees (1.1%), anterior soft tissue impingements in 6 knees (3.3%) atan earlier follow-up, abnormal anteroposterior translation in 5 knees (2.7%), and a fracture ofthe femoral component induced by osteolysis in 1 knee. Two patients with late dislocation ofbearing had preoperative varus deformity more than 15º angulations and 20º flexion contracture.Conclusionfile:///E|/ISTA2010-Abstracts.htm[12/7/2011 3:15:47 PM]
