Therapy of a dislocation of the kneecap

How is a kneecap dislocation treated?

Kneecap dislocation therapy

The aim of any therapy for a dislocation of the kneecap is this Kneecap Permanently centering around plain bearings, as valuable cartilage mass is lost with each dislocation event. Since cartilage tissue is incapable of regeneration, the from birth the amount of cartilage given must be handled carefully.

The more common it becomes one Kneecap dislocation the higher the likelihood of premature Kneecap arthrosis (Retropatellar arthrosis).

An acute patellar dislocation must be immediately be repositioned. A follow-up treatment in a thigh cast optionally follows.

If there is a suspicion of cartilage shearing off (Flake) or if this is confirmed by an MRI examination, arthroscopy (knee mirroring) should be performed to assess the extent of the cartilage damage.
If a flake is found, it should be refixed if possible. To do this, the knee joint has to be opened and the sheared-off fragment has to be fixed again in its place so that no cartilage sliding surface is lost.

In the case of multiple kneecap dislocations, surgical correction of the kneecap should be performed.
Various correction operations are possible here.
The most frequently performed should be mentioned here.

In the operation of the kneecap dislocation, a differentiation is made between soft tissue interventions (tightening / suturing of ligaments) and bony corrective measures. Bony corrective measures should only be taken after growth is complete.

Insall operation

In this surgical method of a kneecap dislocation, the inner capsule is gathered, in a traumatic one Initial dislocation the inner capsule apparatus (medial retinaculum) sewn at the same time. By this measure the course of the Kneecap more on the inside of the Knee joint relocated to prevent further external dislocation.

This surgical method can be used with a lateral release be combined. Here, ligament structures on the outside of the kneecap are severed in order to reduce the tendency of the kneecap to lateralize.

Many other methods are described in the literature.

Appointment with a knee specialist?

I would be happy to advise you!

Who am I?
My name is dr. Nicolas Gumpert. I am a specialist in orthopedics and the founder of .
Various television programs and print media report regularly about my work. On HR television you can see me every 6 weeks live on "Hallo Hessen".
But now enough is indicated ;-)

The knee joint is one of the joints with the greatest stress.

Therefore, the treatment of the knee joint (e.g. meniscus tear, cartilage damage, cruciate ligament damage, runner's knee, etc.) requires a lot of experience.
I treat a wide variety of knee diseases in a conservative way.
The aim of any treatment is treatment without surgery.

Which therapy achieves the best results in the long term can only be determined after looking at all of the information (Examination, X-ray, ultrasound, MRI, etc.) be assessed.

Tuberosity dislocation

The relocation of the kneecap tendon insertion can be used as a corrective measure.

Operation according to Elmslie-Trilat: In this operation, the kneecap tendon (Patellar tendon) at the Shin (Tibial tuberosity) inside (medial) offset.
As a result of the offset, the kneecap runs further inside in its slideway, which makes dislocation significantly more difficult.
This procedure can include soft tissue surgery (e.g. Insall - operation) be combined.


The follow-up treatment must be adapted to the corresponding surgical method.
It is important that the Musculature the thigh is optimally treated with physiotherapy.
Here, special attention must be paid to training the inner front thigh muscles (Vastus medialis muscle) be placed. In this way, the patella shape can also be favorably influenced.
In addition, stretching the hamstring muscles (hamstring muscles) makes sense.
