MPFL reconstruction for patella dislocation

MPFL reconstruction is a surgery done to replace a ruptured or stretched Medial Patellofemoral Ligament (MPFL). This ligament is usually damaged as the result of a patella (kneecap) dislocation. This ligament attaches to the inner side of the patella and inner side of the femur, keeping the patella stable. A kneecap dislocation or ongoing instability of the kneecap may be the reason for MPFL reconstruction surgery.

What would surgery entail?

In cases where the MPFL is excessively weak or torn, reconstruction surgery may be needed to repair the ligament and stabilise the knee joint. MPFL reconstruction is done by both arthroscopic and open surgery. Under general anaesthesia, tiny incisions are made in the front of the knee for the arthroscope and small arthroscopic tools to perform the operation. One of the hamstring tendons is then taken from the back of the thigh and grafted to form a new ligament.

Next, a small tunnel is drilled through the patella, and the new ligament is fitted into place with a button like fitting. Another tunnel is then drilled through the inner side of the femur. The other end of the new ligament is then fitted into the femur tunnel with a button-like fitting. The graft is then fixed in place with a metal or bioabsorbable screw.

What can I expect after surgery?

You will be asked to get up and walk the same day or one day after surgery. Bending and straightening of the knee are encouraged immediately after surgery. This is done to aid mobility and recovery of the joint and is done with the help of crutches or walking aid.

Your knee will be placed in a brace to ensure it stays in position while healing..
You can expect some pain and swell for the next few days to weeks, but Dr Bismilla will prescribe you some medication to help with this. He will also advise that you keep your leg elevated during recovery.

With the help of physiotherapy to aid recovery, flexibility and strengthen the muscles around the knee, you should be able to return to normal after 6 to 8 weeks and enjoy physical activities after a full recovery in about 6 to 9 months.
