Seventeen Year Bilateral Total Knee Postmortem Retrieval Comparing Cement And Cementless Fixation

摘要

Interestingly, a larger amount of bone was present within the porous coated regions when compared to the entombed cement regions. Although the immediate interlock made by the cement appears to be advantageous, the autograft bone chips were shown to be more advantageous to the attachment between the periprosthetic and host bone regions. The results of this case study suggest that bone ingrowth can achieve the same durability as cemented implants. More postmortem studies of this type would be helpful in understanding skeletal attachment in cemented and cementless TKR.
