Total hip replacement. A comparison between cemented (Charnley) and non-cemented (HP Garches) fixation by clinical assessment and objective gait analysis.

In 119 patients with total hip replacement (THR) 61 were operated on with cemented (Charnley) and 58 with non-cemented (HP Garches) fixation. The assessment was performed by clinical examination and objective registration by gait analysis 6 and 12 months postoperatively. The group with cemented fixation (Charnley) demonstrated better results in all variables. The greatest difference between the groups was found at the 6 months' follow-up. The gait analysis was valuable in the assessment of locomotor function.
