Cementless femoral revision arthroplasty. 2- to 5-year results with a modular titanium alloy stem.
Seventy-five consecutive cementless femoral revision arthroplasties were performed, using a modular titanium alloy stem (S-ROM, Joint Medical Products, Stamford, CT). Sixty-six hips were available for complete follow-up evaluation at 2 to 5 years (average, 3.4 years). Independent clinical analysis compared pre- with postoperative modified Harris hip scores and examined patient satisfaction. Independent radiographic analysis was also undertaken. There were two rerevisions, both for hematogenous sepsis. Of the rest, clinical scores improved from a preoperative value of 44 to a postoperative value of 83. Eighty-nine percent of patients were satisfied or very satisfied with the results of surgery. Fifty-two stems had solid bony ingrowth, seven were stabilized by fibrous tissue, and five were radiographically loose. Five-year survival, with rerevision as endpoint, was 96.4%.
