Abstract
We present the results of a retrospective review of 65 CLS uncemented total hip replacements in 47 patients all of whom were less than 65 years of age at the time of surgery. The mean follow-up was 6.5 years and only one case was lost to follow-up. The clinical results were good. The mean (95% confidence interval) Merle d'Aubigne Postel score for pain (max. 6) was 5.42 ± 1.13 (5.13 – 5.71) and for mobility (max. 6) 5.55 ± 0.71 (5.37 – 5.73). The mean score for patient satisfaction (max. 5) was 4.89 ± 0.46 (4.77 – 5.00). The mean total score was therefore 15.97 ± 1.70 (95% confidence interval 15.54 - 16.40) from a maximum of 17 points. There were three revisions over the study period giving a mean (95% confidence interval) survivorship of 96.5% (91.9% - 100%) at five years. We present the results of a radiological review, which show that the surviving implants show evidence of osseointegration. This was achieved despite the lack of a porous or hydroxyapatite coating.
