title: Highly cross-linked polyethylene in posterior stabilized total knee arthroplasty: early results.
abstract: This article examines whether any new complications were associated with highly cross-linked polyethylene in posterior stabilized total knee arthroplasty (TKA) due to its altered mechanical properties. Average preoperative Knee Society Scores (KSS) were 49.7 and 51.5, with a range of movement (ROM) of 3° to 116°, and average postoperative KSS were 87.7 clinical and 89.7, with ROM of 0° to 123°. Postoperative alignment averaged 3.8° of valgus. There were no cases of polyethylene or post failure. Short-term results of posterior stabilized TKAs using highly cross-linked polyethylene show good functional outcomes with no evidence of loosening or tibial post failure.
