ABSTRACT
PURPOSE:
To evaluate the results of total hip arthroplasty (THA) with a CLS expansion acetabular cup using press-fit technique. MATERIALS ANDMETHODS:
One hundred and nineteen primary THA in 102 patients with a CLS expansion cup by press-fit technique were performed consecutively. Eighty-four hips were evaluated for clinical analysis by Harris hip score (HHS) , and 70 hips were evaluated for radiographic analysis, including stability (cup migration and change of position) , remodelling (change of polar gap and trabecular pattern) , and early wear rate of polyethylene after a mean follow up of 4 years and 9 months.RESULTS:
Mean HHS was improved from 44.9 points preoperatively to 90.4 points at the most recent follow up. Initial adequate contact fit was found in 64 hips (91%) . Radiolographically, optimal stabilities of acetabular cup at the most recent follow up were found in all hips. Polar gap in 38 hips (78%) of 48 hips at postoperative radiographs disappeared at most recent follow up. Periacetabular trabecular patterns were maintained or improved in all cases.CONCLUSION:
CLS expansion acetabular cup fixation by press-fit technique guaranteed an excellent implant stability.
