Revision total hip arthroplasty. Long-term results without cement.
The authors present their results for cementless femoral revision arthroplasty using extensively porous coated implants. Patients have been prospectively followed for 5 to 11 years (mean 7.4 years). The revision rate was 5.7%, and the radiographic loosening rate was 1.1%, to give a mechanical failure rate of only 6.9%. As a result of the revision procedure, the pain level was improved for 89.1% of the patients, walking status was improved for 82.8% of the patients, and functional level was improved for 88.5% of the patients. These results compare very favorably with any reports on revision arthroplasty using cement with a similar length follow-up.
