An abnormally low patella - patella baja (also called patella infera) - is a common complication of total knee replacement or opening-wedge tibial osteotomy due to inflammation and scarring within the front of the knee joint and behind the patellar tendon - in …

How does infrapatellar contracture syndrome lead to patella infera/baja? Gradually, the contracting scar tissue may pull the patella itself into an abnormally low position, which is called 'patella infera' or 'patella baja'. This may lead to chronic pain from increased pressure on the upper surface of the patella.

The debridement was not enough, my patella tendon was completely adhesed down to the tibia. He proceeded to do a procedure for patella baja called a Delee osteotomy. A Delee osteotomy is a tibial tubercle transfer for patella baja. The part of the tibia where the patella tendon is attached, is cut away. This bone cut is deep and angled a ...

In patella infera the kneecap (patella) rides too low down the femur . Cause of patella infera Inflammation of the anterior interval behind the patellar tendon may result in the tendon sticking down against the tibia , and the patella is pulled downwards.

As the soft tissues behind and below the kneecap become involved in the scar tissue process, the kneecap may be pulled into an abnormally low position (patella baja or patella infera) The abnormal position of the patella may result in considerable pain when trying to walk, and the knee may be most comfortable in a slightly bent position.

Patellar infera - The patella is pulled downwards towards the tibia. Patellofemoral arthrosis - The softened joint surfaces between patella and underlying groove of the femur disintegrate. The patella infera condition is classified into one of two types based on the damage to the articular cartilage. Several years ago, we described a group of ...

Arthrofibrosis and Patella Baja This ebook discusses ho w arthrofibrosis may result in an abnormally low kneecap ( patella baja ) ... The inflammatory process of arthrofibrosis may affect the region around and behind the kneecap, and lock up …

Check the relation of the bottom of the patella to Blumensaat's line in the 'baja' ('infera') and 'alta' X-rays above. Note also that Blumensaat's line works for patella alta/infera only when the knee is flexed 30 degrees -another good reason to be careful when specifying what films one wants taken. Merchant's View

These changes to the patella tendon are permanent. It also showed damage to the patella articular cartilage. My patella cartilage was already showing the damage from being in this baja state. My OS said the patella was scooping out the groove much like an ice cream scoop with ice cream. Damaging the patella with each scoop.

Both patella alta and patella infera (baja) are forms of malalignment and these are readily appreciated on a lateral X-ray of the knee. The other two views that I mentioned at the onset – the AP and the standing tunnel view – are extremely important for detecting problems in the other compartment of the knee but, relatively speaking, they ...
