This prospective study reviews the two-year results in a series of total hip replacements using the Silent Hip 'neck only' prosthesis. The Silent Hip was used in 15 hips in 14 patients in combination with large bore metal heads and ASR metal cups. Results were analysed using pre-operative and two-year Harris hip scores, Oxford hip scores, and UCLA activity ratings. Radiographs were independently analysed for evidence of implant migration, loosening, and bony hypertrophy. All patients had successful outcomes at two years. The mean Harris hip score improved from 52 to 97.4, with nine patients (10 hips) scoring 100. There were 14 excellent hips and one good hip according to the Harris scoring system. The mean Oxford hip scores improved from 36.8 to 13.8, with nine patients achieving a perfect score of 12. The average UCLA activity rating improved from 5.2 to 8.1. Independent radiographic analysis demonstrated no cases of implant migration or bony hypertrophy. The only complication in the series was one DVT. The Silent Hip is a safe and effective implant in patients with adequate femoral neck bone stock.
