Purpose: This study was conducted to evaluate the clinical and radiographic outcomes of total hip arthroplasty
(THA) using cemented Exeter femoral stem.
Materials and Methods: We reviewed the clinical records and serial radiographs of 64 patients (84 hips) who
underwent THA using a cemented Exeter femoral stem by one surgeon from January 1998 to June 2001. The mean
follow-up period was 3.8 years (3 to 5.5 years). The clinical results were evaluated with Harris hip score (HSS) and
the thigh pain and radiographic results were assessed with serial radiographs. The patients "were examined at two
weeks, three months and six months", during the first postoperative year, "and every year after that".
Results: Mean HSS improved from 56 points preoperatively to 95 points at the time of the last postoperative
follow-up. The thigh pain of most patients decreased. Postoperative cement grade was A in 34 cases, B in 45, C in 5
and D in none. Aseptic loosening was not found while focal radiolucency in Zone I, VII was found in one case during
the follow-up period. Subsidence of the femoral stem was less than 1 mm in 82 cases and was 1 and 1.9 mm in the
other 2 cases. No loss of the height of the medial femoral neck occurred in 76 cases while the loss in the other 6 cases
was less than 1 mm. There were two cases of complication of cement mantle fracture.
Conclusion: This study showed the good clinical and radiographic results of THA with a cemented Exeter femoral
stem at the intermediate-term follow-up. However, a long-term follow-up study will be needed to evaluate the more
precise clinical and radiographic outcomes.
