PCL Reconstruction

The posterior cruciate ligament, (PCL), is one of the strongest ligaments located inside the knee joint. Injuries to the posterior cruciate ligament can occur in several ways, including a hard blow to the shinbone or falling down on a bent knee.

There may be a bony avulsion of PCL which is much more common than an isolated PCL tear. A PCL tear is usually associated with multi-ligamentous injuries of the knee.

Clinical Examination

  • Pain in the back of the knee
  • Posterior drawer test positive
  • Reverse Lachman test positive.

Diagnosis

If there is a bony avulsion of the ACL it can be diagnosed with a good quality radiograph.

MRI is usually needed for confirmation of diagnosis.

PCL reconstruction

Physiotherapy can be tried in some cases.

The most common method involves grafting the damaged PCL with segments of the hamstring tendons. If the surgical process requires the reconstruction of multiple ligaments at one time, different graft materials may be used.

PCL reconstruction process is normally done in one of the following techniques –

  1. Arthroscopic procedure,
  2. Open knee posterior cruciate ligament reconstruction – If the injuries are more serious than the patient may need to undergo an open surgery.
