Background: Growing awareness of the biomechanical contribution of the medial patellofemoral ligament has led to an upsurge in the publication of techniques and trials dealing with reconstructive techniques, warranting a review that includes the most recent evidence.
Study Design: Systematic review.
Methods: The authors undertook a systematic electronic search and rigorous screening process to find and identify published evidence describing the outcomes of medial patellofemoral ligament reconstruction.
Results: Fourteen trials were included for analysis. Although they showed generally excellent outcomes for medial patellofemoral ligament reconstruction modalities, there were several recurring weaknesses. Most were small case series, many had limited follow-up, and a majority employed other adjunctive techniques besides medial patellofemoral ligament reconstruction, making it difficult to distinguish the determining factors in their outcomes.
Conclusion: There is limited but growing evidence that a medial patellofemoral ligament-based surgical approach to patellofemoral instability leads to excellent functional outcomes.

Sulcus-Deepening Trochleoplasty and Medial Patellofemoral Ligament Reconstruction Provide Good Clinical Outcomes in Addressing Patellar Instability at Mid-Term Follow-Up: A Retrospective Case Series.

Purpose: To update previously published clinical and radiographic outcomes of Dejour sulcus-deepening trochleoplasty and medial patellofemoral ligament reconstruction (MPFL-R), at mid-term follow-up, and monitor trends in patient reported outcome scores and satisfaction.
Methods: Using the same cohort of patients from our previously published short-term series of 2-year follow up, interval follow-up was performed on 67 patients (76 knees) with severe trochlear dysplasia and recurrent patellar instability who were prospectively enrolled and underwent Dejour sulcus-deepening trochleoplasty and MPFL-R combined with other patellar-stabilization procedures. Patients with less than 2-year follow-up were excluded.
Association of patellofemoral osteoarthritis on patient-reported outcomes after medial unicompartmental knee arthroplasty: a retrospective cohort study.

Background And Purpose: In contemporary medial unicompartmental knee arthroplasty (mUKA), non-lateral patellofemoral osteoarthritis (PFOA) is not considered a contraindication. However, we still lack knowledge on the association of PFOA severity on patient reported outcome measures (PROMs) after mUKA. We aimed to examine the association between PFOA severity and PROM-score changes after mUKA.

The medial patellofemoral complex provides the primary static restraint to lateral patellar translation and is composed of the medial patellofemoral ligament and medial quadriceps tendon femoral ligament. Multiple techniques including medial patellofemoral ligament and/or medial quadriceps tendon femoral ligament reconstruction have demonstrated good results; however, modification of the femoral fixation technique is required for skeletally immature patients or revision cases in which anatomic bony fixation on the femur is not possible. This technique describes an all-soft-tissue procedure for single-bundle medial patellofemoral complex reconstruction in which the graft is fixed on the adductor tendon while using the medial collateral ligament as a distalizing pulley, for anatomic and isometric recreation of the native ligament.

Purpose: To use a large nationwide administrative database to directly compare usage, complications, and need for revision stabilization surgery after medial patellofemoral ligament reconstruction (MPLFR), tibial tubercle osteotomy (TTO), and combined MPFLR and TTO (MPFLRTTO).
Methods: The PearlDiver Mariner database was queried for all reported cases of MPLFR, TTO, and combined MPFLRTTO performed between 2010 and 2020 using Current Procedural Terminology codes. Subsets from those cohorts with laterality-specific , , codes for patellar instability were used to evaluate 2-year incidence of infection, stiffness, fracture, and revision stabilization with MPFLR and/or TTO.

Background And Objective: The efficacy of medial unicompartmental knee arthroplasty (UKA) in patients with intraoperatively identified patellofemoral osteoarthritis (PFOA) has been a subject of debate. This retrospective study aimed to investigate the early outcomes of UKA in patients with varying intraoperative PFOA conditions and to explore the relationship between the location of PFOA and the position of the prosthesis post-UKA. Our aim was to determine whether the presence of PFOA affects the short-term success of medial UKA.
