Patella luxation

Etiology

 * trauma / congenital disposition (more often ♀, also repeated habitual dislocations)
 * the patella usually Luxates laterally
 * cause of lat. luxation is almost always a congenital disposition: Knee valgus, high position of the patella (patella alta), congenital patella dysplasia, joint hyperlaxity syndrome, etc.

Diagnostics

 * acute dislocation: significant change in knee contour + blocking of movement in semiflexion, haemarthros
 * recurrent dislocation: Anamnesis opposite. patella luxation, congenital. disposition, sy joint hyperlaxity, clinically subluxation to luxation of the patella (examined rather in CA)
 * X-ray] – exclusion of an associated fracture, possibly. [[CT
 * ASK – will most accurately clarify the condition of the joint surfaces + the position of the patella

Treatment

 * reduction in CA, immobilization of the knee for 4-6 weeks
 * in case of recurrent dislocations, surgery – medialization of the patella open / arthroscopically (+ lateral release)
