A complex ligament injury of the knee implies that more than one of
the major knee ligaments have been damaged. The major knee ligaments
are the anterior cruciate ligament (ACL), the posterior cruciate ligament
(PCL), the medial collateral ligament (MCL) and the lateral collateral
ligament (LCL). The LCL has important associated structures grouped
together and is referred to as the postero-lateral corner.
In order to sustain a complex ligament injury of the knee the patient
will usually have experienced a major accident or high energy twisting
injury. In such cases both the treatment and rehabilitation can be
difficult and complicated.
« An MRI scan showing the PCL»
The symptoms of a complex knee ligament injury can be similar to other
ligament injuries. For example, the patient may describe a feeling
of instability of the knee in the same way as with a simple ACL rupture.
Pain may also be an issue.
The diagnosis of complex knee ligament injuries is made both on the
story of injury and clinical examination by the surgeon. Sometimes
examination under anaesthetic or arthroscopy (keyhole surgery) is
used in these cases. MRI scans are a very useful investigation to
clarify the situation.
Complex ligament injuries of the knee are quite rare and treatment
is, by definition, more difficult.
It usually involves multiple ligament reconstruction and a long period
of rehabilitation.
Sometimes if there is severe stretching of the outer ligaments of
the knee you will also require an osteotomy to try and improve the
alignment of the knee.
Results of surgery for complex knee ligament injury depend on the
specific injury and are less predictable than for simple anterior
cruciate ligament ACL reconstruction.
