There has been increasing interest in investigating the medial patellofemoral ligament (MPFL) during the last fifteen years. This is due to the recognition of the MPFL as the primary static soft-tissue restraint to lateral patellar displacement and the association of MPFL injury with primary traumatic patellar dislocation. The MPFL often heals poorly and thus rarely regains its full function. Numerous surgical techniques have been described for reconstruction of this important structure. This paper reviews the relevant anatomy and biomechanics, published reconstruction options, and describes the surgical technique performed at our institution--that of using a quadriceps autograft to reconstruct the MPFL.

Introduction: The medial patellofemoral ligament (MPFL) is the main patellar stabilizer in low knee flexion degrees (0-30°). Isolated MPFL reconstruction (MPFLr) is therefore considered the gold standard of surgical procedures for low flexion patellofemoral instabilities (PFIs). Despite excellent clinical results, little is known about the effect of MPFLr on kinematic parameters (KPs) of the patellofemoral joint in vivo.

Purpose: Sulcus-deepening trochleoplasty (TP) effectively treats patellofemoral (PF) instability (PFI) caused by high-grade trochlear dysplasia (TD), but current evidence is based on small case series. We hypothesised, that TP would result in significant functional improvements and a low re-dislocation rate but would not accelerate the progression of PF cartilage deterioration.
Methods: We retrospectively reviewed all TP cases performed by a single surgeon between 2015 and 2021.

Introduction: medial patellofemoral ligament reconstruction (MPFLr) is a common surgical procedure for treating patellar instability. Grafts can be fixed to the femur using a bone-tunnel technique with an interference screw. However, this may lead to femoral tunnel enlargement (FTE) post-operatively.

Patellar dislocation is a common knee injury, with concomitant pathoanatomical risk factors that synergistically interact and predispose to patellofemoral instability. Medial patellofemoral ligament (MPFL) reconstruction has demonstrated significant potential in the re-establishment of MPFL anatomic and biological function, with low patellar redislocation rates. Although many techniques for MPFL reconstruction have been developed, challenges such as patella fractures and high costs persist.

Background: Postoperative knee arthrofibrosis after arthroscopic ligament reconstruction is a serious complication. Among adolescents, risk factors for postoperative arthrofibrosis are not well characterized and the effectiveness of early manipulation under anesthesia (MUA) is not well established.
Purposes: To identify risk factors for arthrofibrosis after arthroscopic knee ligament reconstruction in adolescent patients and to evaluate the safety and effectiveness of early MUA.
