An analysis of the survival rate of total-condylar total knee prostheses with posterior stability.
Survival rate tables are an adequate and relatively new means of evaluating prostheses of the knee. These tables may be used to make a clear distinction between success and failure. In a study of 160 prostheses followed-up over a period of 9 years, a Total-Condylar knee prosthesis with posterior stability has a 90% probability of surviving for the entire period, based on mechanical and radiological failures, and a 96% probability based on failures that required its removal. The probability of mechanical or radiological failure is 1% per annum.
