Consecutive series of 226 journey bicruciate substituting total knee replacements: early complication and revision rates.

Christen B, Neukamp M, Aghayev E - BMC Musculoskelet Disord (2014)

Bottom Line: 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.A tendency towards higher complication rates was observed in female patients, although it was not significant (p = .066).

ABSTRACT

Background: The 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.

Methods: Between 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.

Results: The 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).

Conclusions: The 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.

Fig1: Early complication, minor and major revision rates, and the proportion of patients with complications in whom no revision was required by the treatment year.

Mentions: Table 4 and Figure 1 show the decrease in early complication rates by the treatment year; the linear trend was not significant (p = .22). The complication rate during the first postoperative year was around 50% greater than the average rate of the five years studied.Table 4
