Management of avulsion injury of the PCL with reattachment.

Twenty-eight cases of avulsion injury of the posterior cruciate ligament (PCL) treated by reattachment were followed up to evaluate the results. Evaluation was based on appropriate functional and dynamic criteria: the results are classified as good, fair or poor. The interval between injury and repair ranged from 3 days to 2 months with a mean 4 weeks. The follow-up period ranged from 3 to 10 years with a mean of 5 years. The evaluation revealed 27 (96 per cent) good, one (4 per cent) fair and no poor results. It is apparent that operative reattachment is the treatment of choice for avulsion injury of the PCL, especially in early cases.
