Lateral release

 

Ligament, tendon and fibrous tissue stays hold the normal patella in a central position. Sometimes the tissues are too tight on the lateral side, and pull the patella into a poor position.

 

The lateral release procedure attempts to re-position the patella in a better position by cutting the tissues on the lateral side.

What does a lateral release entail?

The patella is supported on both sides by the fibrous retinacula, the most important of which is the lateral retinaculum. Sometimes the retinaculum is too tight on the lateral side and this results in 'patellar tilt', excessive lateral pressure syndrome and anterior knee pain.

In the procedure of lateral release, which is nowadays usually performed arthroscopically from inside the joint, the retinaculum is cut on the lateral (outer) side of the knee, allowing the patella to move into a better position.

  "We frequently hear these words when talking about....[lateral retinacular release]: “I am going to perform a very minor surgery that can do you no harm, and still leaves the door open for more aggressive realignment procedures”. There is nothing further from the truth. This way of thinking is a big mistake..."

• Quote from peer-reviewed paper:

  "For many years, lateral retinacular release of the patella has been used indiscriminately for the treatment of various extensor mechanism abnormalities, presenting conflicting functional results....Nowadays, there is clear evidence for its indication in the lateral patellar hypercompression syndrome associated with anterior knee pain, as long as there is no related instability"
