title: Clinical experience with a modular noncemented femoral component in revision total hip arthroplasty: 4- to 7-year results.
abstract: A series of 163 revision total hip arthroplasties performed using a modular proximally porous-coated device was reviewed. Twenty patients died before achieving minimum follow-up, and 13 hips with Paprosky type IV femora were excluded. One patient was lost to follow-up. Minimum 4-year clinical data on the remaining 129 hips showed an improvement in modified Harris hip scores, from an average of 47.7 to 87.5. Spot welds at the sleeve-bone interface were found in 83 of the 102 hips with minimum radiographic follow-up. The aseptic failure rate was 2.9%; these hips showed progressive subsidence, with 1 resulting in the only repeat revision in the series. Three hips had osteolytic lesions of <5 mm; none threatened implant stability. There were no complications related to modularity.
