“…Trochleoplasty carries a high risk of cartilage damage and of permanent modifications of the knee joint kinematics. All these factors are critical, and they may result in the development of early osteoarthritis [123][124][125][126][127][128][129][130] .…”

Primary traumatic patellar dislocation is common, particularly in young active individuals. A consensus on its management is still lacking. The present work provides easily accessible guidelines to be considered as recommendations for a good clinical practice developed through a process of systematic review of the literature and expert opinion, to improve the quality of care and rationalize the use of resources. Level of evidence: Ia.

“…Bone is removed from beneath the trochlear groove to deepen it, or a new superior trochlear groove is fashioned by removal of an excessive superior trochlear ridge. 75,76 Both techniques require careful handling and replacement of the osteochondral surface. These procedures are performed infrequently in the United States and are typically reserved for patients who have failed other procedures or who have complex forms of patellofemoral instability.…”

The extensor mechanism of the knee plays an important role in many movements of the lower extremity. Although its main function is to extend the knee, it also stabilizes the patellofemoral joint and resists passive flexion of the knee when landing from jumping. Pathologic conditions of the extensor mechanism can be acute or chronic, and they can negatively affect daily activities. Fortunately, many surgical treatments are available aimed at restoring function to the injured extensor mechanism. Understanding the surgical techniques and common complications of these procedures enables the radiologist to recognize expected and unexpected postoperative imaging appearances.

“…The combination of proximal and distal procedures as well as arthroscopic and open surgery enables immediate and precise correction of marked patellofemoral malalignment and accomplishment of almost ideal congruency. Despite that fact, in the reviewed literature, postoperative outcomes, concerning patellar pain, slipping and overall functional results, apparently were not always ideal 18,[24][25][26][27] . On the other hand, nonoperative treatment, even without noticeable correction of the alignment, in a number of patients, establishes good functional control of the knee extensor, significant reduction and sometimes even complete subsidence of the major symptoms.…”

Surgical treatment of symptomatic patellofemoral malalignment: Do we need an ideal patellofemoral congruency to solve the symptoms?

Background/Aim. The aim of this prospective nonrandomized study was to test functional results of different surgical strategies in the operative treatment of symptomatic patellofemoral malalignment. Our hypothesis was that immediate extensive surgery does not have serious advantage comparing to "step by step" procedure, regarding the main symptoms and functional end result. We wanted to check whether obtaining ideal surgical patellofemoral congruency is an essential prerequisite for subsidence of the major symptoms of patellofemoral malalignment. Methods. The study included 35 patients with patellofemoral malalignment who had persistant major symptoms: patellar pain and slipping, 3 months after nonoperative treatment. Divided into three groups, they all underwent the realignment surgery, but in different extent and sequence: immediate extensive surgery, step by step surgery, and only proximal realignment. Their overall functional scores as well as major symptoms were assessed at the beginning, after the surgery, and during the 3-years follow-up period and then, compared at the end. Results. There was no significant difference in the functional results among the groups, neither at the beginning (p = 0.1318) nor at the end of the study (p = 0.3996), but the results at the beginning compared to those at the end of the study showed a statistically significant difference in all three groups (p1 = 0.005062; p2 = 0.011719; p3 = 0.000352). The same result was in regard to the major symptoms. Conclusion. The study confirmed that insisting on immediate extensive surgery in order to achieve precise and complete congruency of the patellofemoral joint, did not prove its advantage over the less invasive, individual surgical approach concerning functional scores and major symptoms.
