ResultsMean follow-up was 6 yrs (SD 1.7). Mean radiographic follow-up was 5.2 yrs (SD 1.2).Radiographs were available for 83 hips. Mean HHS improved from 43 preoperative (range 15–68) to 98 (range 86-100, p < 0.0001). Mean WOMAC score improved from 56 (range 15-94) to12 (range 0-63, p < 0.0001). Flexion improved from 95 o (range 50-115) to 102 o (range 90-120,p < 0.0001). Complications included trochanteric fx (6 mo) without component removal,traumatic femoral Fx (40 days) with stem replacement, and one dislocation. No other devicerelated adverse events were reported. No peri-acetabular osteolysis was observed. Six yearsurvival was 100% for the acetabular shell / modular metal liner combination.ConclusionExcellent mid-term results were obtained in a young, active cohort treated with modular MoMTHA. No AVAL, pseudotumor, unexplained pain or other complication attributable to weardebris or the MoM articulation was observed. These findings indicate that THA with thePinnacle modular MoM bearing performs well in a high demand population at mid termfollow-up.Thursday, October 7, 2010, 16:50-17:40Session B8: Management of Complications in TKATreatment of Periprosthetic Osteolysis Using Trabecular Metal in RevisionKnee ArthroplastyDaniel Kendoff - Endo Klinik - Hamburg, GermanyChristian Schmitz - Endo Klinik - Hamburg, Germany*Wolfgang Klauser - Endo Klinik - Hamburg, Germany*Email: Wklauser@t-online.deIntroduction: Several options exist for the treatment of periprosthetic osteolysis in revision kneesurgery. We describe our preliminary short-term experiences using trabecular metal (TM)technology in order to fill bony defects either on the femoral or on the tibial side.Material and Methods: 52 revision knee surgeries in which this TM technology had been usedwere retrospectively reviewed clinically and radiographically. Indication for revision included51 cases with aseptic loosening of Total Knee Arthroplasty. In one case of periprosthetiinfection, a staged revision procedure was performed. Assessment of bone loss included theAORI classification (1989) and was performed pre- and intraoperatively. Clinical evaluationwas performed using the HSS score. In 6 cases in addition to usng the TM cones, an impactiongrafting technique was performed.Results: Average follow up was 22 months. So far, not loosening of a TM cone neitherfile:///E|/ISTA2010-Abstracts.htm[12/7/2011 3:15:47 PM]
