title: Severe instability despite a constrained knee prosthesis with central stabilizer. A case report.
abstract: We report on the clinical failure of a constrained total condylar knee with a central stabilizer in a revision case. The knee was very unstable, with a valgus deviation of more than 45. At surgery, the instability was normalized, but the valgus deviation recurred during the first year.
