Migration of femoral components in TKA with either Highly cross linked or conventional polyethylene .
Five-year migration of uncemented femoral components in total knee arthroplasty with either highly cross-linked or conventional polyethylene inserts: a blinded randomized controlled trial using radiostereometric analysis.
Bone Joint J. 2024 01-Aug;():. 10.1302/0301-620X.106B8.BJJ-2023-1429.R1Ninety-five patients with end-stage osteoarthritis undergoing total knee arthroplasty were randomized to receive either a highly cross-linked polyethylene (HXLPE) insert (n=48) or a conventional polyethylene (PE) insert (n=48). The primary outcome was the migration of the femoral component measured by radiostereometric analysis over five years. Secondary outcomes included patient-reported outcome measures and clinical scores assessed at multiple follow-up points. Overall, the results of the study revealed no significant difference in femoral component migration between HXLPE and PE inserts.
