Knee replacements: Total knee replacements have traditionally been cemented on the femoral and tibial sides, but non-cemented versions are becoming more attractive for surgeons. Solid fixation to bone is paramount with non-cemented components. Cement is necessary if this is not achieved. In your case, the femoral component was likely well fixed, but tibial component likely required cement to ensure good fixation

Yes, normal: This is called "Hybrid Fixation". When the femur is Un-cemented and the tibia is cemented. The long term results are equivalent to all cemented implants. There are also fully cemented installations and fully un-cemented installations. When any of these techniques are used properly, the long term fixation is similar. Best of luck to you.
