title: [CLS multicenter study--8-year results].
abstract: The principles of proximal fixation of cementless endoprostheses is established already. This theory was the subject of the present multi-center study of 22 clinics. Between 1984 and 1992 all 1830 patients with an uncemented CLS press-fit stem had a clinical and radiological follow-up examination and computer documentation. The evaluation of the clinical results are based on the Merle d'Aubigné score. In 91% we found a good or excellent result. For the remainder of patients (9%) with a score less than 14 each case has been especially analysed. The incidence of femor component loosening was less than 1% within the average follow-up time of 2.5 years. The medium-term results with the uncemented CLS press-fit stem confirmed the idea of proximal load induction on the femur.
