Patellar dislocation is an injury in which the kneecap protrudes from the intercondylar furrow. In order for dislocation to occur, there must be an additional cause (trauma) or pathology in the anatomy of the knee joint, which may include, among others, lateral positioning of the tibial tuberosity, bone development disorders (patellofemoral dysplasia), generalized joint laxity, previous knee injury , deformity of the foot or ante-thigh bone ante. The knee joint is most prone to patellar dislocation at the moment of internal rotation of the thigh in relation to the foot set on the ground, as well as flexion and deformation of the knee with simultaneous strong tension of the quadriceps muscle. In this case, the kneecap is most often dislocated laterally (outwards), often causing damage to the soft tissues of the knee joint area.

Surgical treatment of a patellar dislocation is the target treatment for recurrent (habitual) patellar dislocation and when it is damaged:

cartilage-bone fragment of the patella
medial patellar retinaculum,
cartilage surfaces
In the above cases, knee surgery is necessary, because leaving the unstable kneecap and not covering the resulting damage may consequently lead to inflammation of the patellofemoral joint with synovial swelling and numerous exudates, as well as destruction of the articular cartilage by abnormal abrasive forces.

The time of rehabilitation after surgery depends on the extent of the damage, the type of treatment procedures and the patient's level of activity. The use of arthroscopy allows for a significant reduction in postoperative pain, shortening the hospital stay and reducing the risk of postoperative complications and faster return of the patient to daily functioning.

After the surgical treatment of the patellar dislocation, full load on the operated limb, obtaining the correct gait pattern on a varied basis and obtaining the correct deep feeling (prioprioception) and 100% return to the activity of everyday life, work and sports without functional disorders and pain, is achieved just a few weeks after the performance arthroscopy.
