A modular cementless stem vs. cemented long-stem prostheses in revision surgery of the hip.
Modular cementless revision prostheses are being used with increasing frequency. In this paper, the authors reviewed risk factors for the outcome of the Link MP stem and report implant survival compared to conventional cemented longstem hip revision arthroplasties. They used data recorded in the Swedish Hip Arthroplasty Register. 812 consecutive revisions with the MP stem (mean follow-up time 3.4 years) and a control group with 1,073 cemented long stems (mean follow-up time 4.2 years) were included. The average age at revision surgery for the MP stem was 72 (SD 11) years.
The cumulative survival with both reoperation and revision as the endpoint was better for the cemented stems with up to 3 years of follow-up. Thereafter, the survival curves converged, mainly because of increasing incidence of revision due to loosening in the cemented group.
The researchers recommend the use of cemented long stems in patients with limited bone loss and in older patients.
