Abstract
Aim: To evaluate the outcome of uncemented femoral revision after total hip arthroplasty using the CLS system at Southland Hospital, Invercargill, between 1995 and 2001.
Methods: A retrospective study of 28 hips, representing the total experience of Southland Hospital with the CLS femoral prosthesis for revision surgery. For evaluation we used the Harris Hip Score and reviewed the radiographs.
Results: Twenty-eight hips(23 male and five female),with an average age of 66 years(33 years to 82 years). The mean interval from the primary surgery to the revision was 7.6 years (range one day to 24 years). The majority (60%) of the revisions was for aseptic loosening, 10% for infection, 10% for periprosthetic fracture and the remainder for recurrent dislocation. There was one case of a mismatch of the femoral and acetabular components requiring revision on the same day. The majority of patients reported a favourable outcome, two experienced serious complications, neither requiring revision.
Conclusions: Our results suggested that the CLS stem was a very useful method of correction following failure of total hip arthroplasty, with a high level of patient satisfaction.
