Options for damaged knee ligaments in biologic knee replacement (part 1d of a course)

For the unstable knee where there has been ligament damage such as an ACL tear, a PCL tear, a posterolateral corner tear or a medial collateral ligament (MCL) tear – which are the most common injuries that we see – we want to stabilise that joint as part of any biologic knee reconstruction. We approach that in the following way –

For reconstruction of ruptured ligaments in the knee when we are doing a biological joint reconstruction, we don’t want to sacrifice any of the patient’s own tissue if it is not necessary. Up until about 5 years ago we felt as though allograft tissues were not as reliable as autograft tissues.

Once we were able to obtain sterilised allograft tissues whose biomechanical properties had not been damaged by the sterilisation process then we felt comfortable moving forward to use those tissues in replacement of autogenous tissues. We did not want to ‘rob Peter to pay Paul’, that is we did not want to damage one part of the knee in order to rebuild another part of the knee. Over the last 5 years our results of allograft tissue have matched our autograft tissue except that the patients have much less pain and a much faster rehabilitation.
