title: Initial experience of the Journey-Deuce bicompartmental knee prosthesis: a review of 36 cases.
abstract: We evaluated the effectiveness of a novel bicompartmental knee arthroplasty prosthesis for the treatment of degenerative disease affecting the medial and patellofemoral compartments. The study included 36 knees in 32 patients with a mean follow-up of 21 months. The mean Knee Society functional survey and Western Ontario McMaster Osteoarthritic Index Survey scores were 65.4 and 75.8, respectively. Thirty-one percent of patients were unsatisfied with the surgery, and 53% stated that they would not repeat the surgery. We report an overall survival rate of 86% with one catastrophically failed tibial baseplate. We conclude that this prosthesis provides inconsistent pain relief and unacceptable functional results for bicompartmental arthritis. Short-term survival of this prosthesis was unacceptably low, and therefore, we no longer implant it at our institution.
