Does High-Activity Behavior Compromise Outcome at a 9-14-Year Interval Following a Ceramic-on-Ceramic Total Hip Arthroplasty? A Preliminary Report
2011
Ninety-five ceramic-on-ceramic hips from a single center were reviewed to investigate whether patients' postoperative UCLA activity level of 9 or 10 in the ensuing 9-14 years following surgery negatively affected long-term radiographic and clinical outcome compared with those with less aggressive activity. Ten patients (10 hips) reported level 9-10 scores at some time after their replacement. Six of these had current radiographs. No patients had loosening, impending loosening, or component failure. Of 6 patients, 3 (50%) had at least one proximal femoral zone of radiolucent lines. This is in contrast with 2 of 39 (5.1%) in those with an activity score of 8 or less.
