Posterior Cruciate Ligament Reconstruction

The posterior cruciate ligament links the tibia, the shinbone,  to the femur, the thigh bone, and is important in controlling the movement of the two bones, particularly during sport. The ligament is typically damaged during sporting activity by forcing the tibia backwards when the knee is flexed.

Reconstruction is generally only required when the knee remains unstable. Patients are generally required to stay in hospital for one night post operatively.  The procedure involves removing the damaged cartilage and replacing it with a graft of the patients own tissues. Most of the procedure is done arthroscopically, keyhole surgery.


Patients will require a straight leg brace for the first fortnight following surgery. After this, a physiotherapy programme will begin. For the first four weeks, this will involve passive bending of the knee (physiotherapist assisted). 

From four to six weeks onwards the exercises will progressively increase so that patients should be walking well without assistance or a limp after a few months. High impact sports are not recommended for at least six months after surgery.
