Forty-two patients (younger than 65 years) with osteoarthritis were operated on with an uncemented CLS stem and randomized to early unrestricted weight bearing combined with intensive physiotherapy or to partial weight bearing combined with self-training. Radiostereometric analysis showed 1.2 (+0.11 to -6.76) mm subsidence of the stem at 24 months in both groups. There was no significant difference in the migration pattern between the unrestricted and partial weight bearing groups. Actual loading on the operated leg, measured with the F-scan system, did not influence the migration of the stem. There was a strong correlation between the average subsidence at 3 and 24 months (r = 0.96). Early full weight bearing and active rehabilitation can be used for the uncemented CLS stem without increased risk of early loosening.
