Published: December 2016

Superior dislocation of the patella with intact patellar tendon is a rare condition. Most cases in literatures were diagnosed by clinical examination and plain radiography; however there are many cases that were misdiagnosed as patellar tendon rupture. In this case, we demonstrate the use of ultrasound for diagnosis of superior dislocation of the patella in the emergency department. We also include a literature review of similar cases and discuss the advantages of different types of imaging for diagnosis in this condition.

Background: Hemophilic arthritis (HA) is associated with significant changes in the morphology of mature knee joints due to abnormal growth plate development. Previous studies have established marked distinctions between the femur and tibia of subjects with Haemophilia and those with osteoarthritis (OA). This study explored the morphological characteristics of the patella and patellofemoral joint in subjects with Haemophilia.

Background: Although chronic quadriceps tendon rupture and defect are rare, they pose significant challenges in surgical treatment. In these cases, quadriceps tendon reconstruction is necessary. Either autologous or allogeneic tendons have been used for this reconstruction.

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.
