Management of first-time patellar dislocation: The ESSKA 2024 formal consensus-Part 2.

Purpose: To provide recommendations for the treatment of patients with first-time patellar dislocation (FTPD). Part 2 focused on nonoperative treatment, bracing, rehabilitation, indications for surgery and surgical strategies.

Methods: The consensus was performed according to the European Society for Sports Traumatology, Knee Surgery and Arthroscopy consensus methodology.

Management of first-time patellar dislocation: The ESSKA 2024 formal consensus-Part 1.

Purpose: To provide recommendations for the treatment of patients with first-time patellar dislocation (FTPD). Part I focused on clinical presentation, symptoms, diagnosis, evaluation and imaging.

Methods: Fifty-four orthopaedic surgeons and one physiotherapist from 20 countries across Europe were involved in the consensus, which was the FTPD.

Knee landmarks detection via deep learning for automatic imaging evaluation of trochlear dysplasia and patellar height.

Objectives: To develop and validate a deep learning-based approach to automatically measure the patellofemoral instability (PFI) indices related to patellar height and trochlear dysplasia in knee magnetic resonance imaging (MRI) scans.

Methods: A total of 763 knee MRI slices from 95 patients were included in the study, and 3393 anatomical landmarks were annotated for measuring sulcus angle (SA), trochlear facet asymmetry (TFA), trochlear groove depth (TGD) and lateral trochlear inclination (LTI) to assess trochlear dysplasia, and Insall-Salvati index (ISI), modified Insall-Salvati index (MISI), Caton Deschamps index (CDI) and patellotrochlear index (PTI) to assess patellar height. A U-Net based network was implemented to predict the landmarks' locations.

Imaging evaluation of patellofemoral joint instability: a review.

The multifactorial origin of anterior knee pain in patellofemoral joint disorders leads to a demanding diagnostic process. Patellofemoral misalignment is pointed out as one of the main causes of anterior knee pain. The main anatomical risk factors of patellofemoral instability addressed in the literature are trochlear dysplasia, abnormal patellar height, and excessive tibial tubercle-trochlear groove distance.

Mosaicplasty Using Grafts From the Upper Tibiofibular Joint.

Autologous mosaicplasty has been widely used for the treatment of focal, full-thickness, articular cartilage lesions of the knee and ankle joints. Commonly, the autografts are harvested from non-weight-bearing areas of the knee joint, leading to associated donor-site morbidity and representing a considerable disadvantage. This Technical Note presents a mosaicplasty procedure for harvesting autologous osteochondral plugs from the upper tibiofibular joint to repair articular cartilage defects.

Reverse shoulder arthroplasty for irreparable massive rotator cuff tears: a systematic review with meta-analysis and meta-regression.

Background: Massive rotator cuff tears (MRCTs) are very large tears that are often associated with an uncertain prognosis. Indeed, some MRCTs even without osteoarthritis are considered irreparable, and nonanatomic solutions are needed to improve the patient's symptoms. Reverse shoulder arthroplasty (RSA) is an option that can provide a more predictable pain relief and recovery of function.

Mesenchymal Stem Cell Secretome: A Potential Tool for the Prevention of Muscle Degenerative Changes Associated With Chronic Rotator Cuff Tears.

Background: Massive rotator cuff tears (MRCTs) are usually chronic lesions with pronounced degenerative changes, where advanced fatty degeneration and atrophy can make the tear irreparable. Human mesenchymal stem cells (hMSCs) secrete a range of growth factors and vesicular systems, known as secretome, that mediates regenerative processes in tissues undergoing degeneration.

Purpose: To study the effect of hMSC secretome on muscular degenerative changes and shoulder function on a rat MRCT model.

Osteochondral transplantation using autografts from the upper tibio-fibular joint for the treatment of knee cartilage lesions.

Purpose: Treatment of large cartilage lesions of the knee in weight-bearing areas is still a controversy and challenging topic. Autologous osteochondral mosaicplasty has proven to be a valid option for treatment but donor site morbidity with most frequently used autografts remains a source of concern. This study aims to assess clinical results and safety profile of autologous osteochondral graft from the upper tibio-fibular joint applied to reconstruct symptomatic osteochondral lesions of the knee.

Empirical antibiotic therapy in prosthetic joint infections.

When dealing with prosthetic joint infections (PJI) there is often the need to start antibiotic therapy without having identified the underlying pathogen. Under these circumstances there is no consensus regarding which antibiotic to use. We aimed to produce local recommendations for empirical antibiotic treatment of PJI by describing the microbiological spectrum involved and respective antibiotic susceptibility profile.
