We present a case of a 44-year-old gentleman with a left post-traumatic chronic patellar dislocation that has been neglected and remained irreducible for 20 years. Our patient has maintained his full knee range of motion and has minimal symptoms and hence was treated nonoperatively. We also present a review of the rather scarce literature of similar cases and the decision-making process performed in our case to decide for nonoperative management.
Early surgical management of this condition may not be warranted if the patient is able to perform high-demand physical activities. However, a later surgery may be indicated when/if his symptoms and/or function deteriorates.
