“…Advocates for medial imbrication, as opposed to reconstruction of the medial patellofemoral ligament, cite the potential for overload of the patella with a graft reconstruction 43 . The native medial patellofemoral ligament has a load to failure of 208 N 52 , and a hamstring graft used to reconstruct the medial patellofemoral ligament can generate up to 1600 N 43 . However, because medial imbrication is a nonanatomic procedure, it can result in excessive medialization of the patella or abnormal tracking.…”

Recurrent patellar instability can result from osseous abnormalities, such as patella alta, a distance of >20 mm between the tibial tubercle and the trochlear groove, and trochlear dysplasia, or it can result from soft-tissue abnormalities, such as a torn medial patellofemoral ligament or a weakened vastus medialis obliquus. Nonoperative treatment includes physical therapy, focusing on strengthening of the gluteal muscles and the vastus medialis obliquus, and patellar taping or bracing. Acute medial-sided repair may be indicated when there is an osteochondral fracture fragment or a retinacular injury. The recent literature does not support the use of an isolated lateral release for the treatment of patellar instability. A patient with recurrent instability, with or without trochlear dysplasia, who has a normal tibial tubercle-trochlear groove distance and a normal patellar height may be a candidate for a reconstruction of the medial patellofemoral ligament with autograft or allograft. Distal realignment procedures are used in patients who have an increased tibial tubercle-trochlear groove distance or patella alta. The degree of anteriorization, distalization, and/or medialization depends on associated arthrosis of the lateral patellar facet and the presence of patella alta. Associated medial or proximal patellar chondrosis is a contraindication to distal realignment because of the potential to overload tissues that have already undergone degeneration.

“…16 The MPFL fans out toward its superomedial patellar insertion, with a wider base compared with the femoral origin. 17 Two functional bundles of the MPFL have been described 18 : the inferior-straight bundle, which is the main static soft tissue restraint, attaching to the midaspect of the medial border of the patella, and the superior-oblique bundle that serves as the main dynamic soft tissue restraint. The distance between the insertions is 10 to 12 mm.…”

The growing number of patients undergoing arthroscopy or surgery of the knee for ligamentous injuries has led to a greater need for postoperative imaging because of poor outcome, recurrent symptoms, or a new injury. MRI is the most important imaging method when evaluating the postoperative knee. Radiologists should be familiar with the particular reconstruction technique applied to each examinee, know the spectrum of normal postoperative findings, recognize those findings that may be related to symptoms of failed reconstruction, as well as those lesions that are irrelevant to the previous surgery yet responsible for the new clinical symptoms. In view of the continually evolving surgical techniques, this review presents the current concepts of MRI evaluation of the postoperative knee ligaments based on recent literature reports.
