Abstract

Low Contact Stress moveable bearing (meniscal and rotating) total results are reported in a prospective FDA-related series. Multi-center results (918 cemented, 963 cementless) were good/excellent in over 95%. More recently analyzed meniscal bearing data in non-inflammatory arthritis revealed good/excellent results in 93.7% of 355 cemented and 93.5% of 451 cementless knees with 2-5 year follow-up. Personal experience with 275 LCS knees (all types/all diagnoses) over 2 years revealed 97.4% good/excellent results. Evaluation scores improved from 53 to 89 points. Device-related complications have decreased from 5.8% cemented to 2.8% cementless. However, fewer sizes were available in the cemented series, contributing to increased loosening. Tibial bearing problems were under 2%. Patella complications have remained under 1%, with or without patella resurfacing. Survival analysis has been greater in the cementless group. The LCS design has remained unchanged for 11 years.
