Abstract

BackgroundThe Journey bicruciate substituting BCS total knee replacement TKR is intended to improve knee kinematics by more closely approximating the surfaces of a normal knee. The purpose of this analysis was to address the safety of Journey BCS knees by studying early complication and revision rates in a consecutive case series.

MethodsBetween December 2006 and May 2011, a single surgeon implanted 226 Journey BCS total knee prostheses in 191 patients 124 women, 67 men who were eligible for study. Mean age at surgery was 68 years 41–85 years.

Outcome measures were early complications and minor and major revision rates. All complications were considered, irrespective of whether conservative treatment or revision was required.

ResultsThe average implantation time was 3.5 years range 1.3-5.8 years. Thirty-three complications 14.6% of 226 knees required minor or major revision surgery in 25 patients. The remaining eight patients were treated conservatively. Sixteen minor revisions were performed in 12 patients. Thirteen major revisions were required in 13 patients, which results in a rate of 1.65 major revisions per 100 component years. The linear trend of the early complication rate by treatment year was not significant p = .22.

Multivariate logistic regression showed no significant predictors for the occurrence of a complication or for revision surgery. A tendency towards higher complication rates was observed in female patients, although it was not significant p = .066.

ConclusionsThe complication and revision rates of the Journey BCS knee implant are high in comparison with those reported for other established total knee systems. Caution is advised when using this implant, particularly for less experienced knee surgeons.
