The management of lateral patellar dislocation: state of the art

Biomechanical Evaluation of the Medial Stabilizers of the Patella

“…The awareness of the MPFL and its role in patellofemoral stability is relatively recent; however, MPFL reconstructions for lateral patellar instability are now standard of care in surgery for patellar stabilization after a trial of nonoperative treatment. 1 The anatomic features of the MPTL and MPML have only been more recently defined, and further study is necessary to determine when repairs or reconstructions of these distomedial patellar stabilizers may be required. Our study has helped to further define the biomechanical properties of the MPTL and MPML.…”

Computational approach to correcting joint instability in patients with recurrent patellar dislocation

“…Patients with persistent symptoms of patellar instability are candidates for surgical interventions, with treatment options that include MPFL reconstruction, tibial tubercle osteotomy, sulcus‐deepening TP, or combinations of these procedures . However, currently, there is no universally accepted algorithm for choosing the appropriate procedure(s) for a particular individual . Studies that evaluate MPFL reconstruction (MPFLR) in patients without identifying predisposing factors make it difficult to extrapolate their success to patients with one or more factors .…”

“…Little research has been done to determine the minimally invasive procedure to prevent recurrent patellar dislocation on symptomatic knees. Researchers have compared the outcomes of different surgeries, however, the patient‐specific indicators for which surgery to perform is relatively unknown . Furthermore, studies often use subjective measures to compare pre‐ and post‐operative performance, with patients often unable to return to pre‐injury performance despite reducing further patellar dislocation …”

“…Researchers have compared the outcomes of different surgeries, 25,30,34 however, the patient-specific indicators for which surgery to perform is relatively unknown. 29 Furthermore, studies often use subjective measures to compare preand post-operative performance, 8 with patients often unable to return to pre-injury performance despite reducing further patellar dislocation. 27 Although clinical studies provide vital in vivo information about joint anatomy, mechanics, and the efficacy of treatment plans, there is a large amount of inter-subject variability that makes it difficult to use clinical data to determine treatment for an individual.…”
