Patellar Instability

Excerpt

Patellar instability, by definition, is a condition where the patella bone pathologically disarticulates out from the patellofemoral joint, either subluxation or complete dislocation. This most often involves multiple factors, from acute trauma, chronic ligamentous laxity, bony malalignment, connective tissue disorder, or anatomical pathology. Over time, patients with patellar instability can have debilitating pain, limitations in basic function, and long-term arthritis.
