[Refixation of osteochondral flake fractures after patellar dislocation-The parachute technique].
Oper Orthop Traumatol
December 2024
Sektion Sportorthopädie, Klinikum rechts der Isar, Technische Universität München, Ismaninger Str. 22, 81675, München, Deutschland.
Objective: Patellar dislocations are a common occurrence in orthopedic practice, often accompanied by osteochondral fractures of the retropatellar cartilage surface, known as flake fractures, in up to 58% of cases. The parachute technique represents a simple and cost-effective surgical option aimed at restoring osteochondral integration and preserving native cartilage.
Indications: Flake fracture of the patella with osteochondral fragments.
Safety and efficacy of placental mesenchymal stromal cells-derived extracellular vesicles in knee osteoarthritis: a randomized, triple-blind, placebo-controlled clinical trial.

Article Synopsis
- - The study explored the safety and effectiveness of injecting placental mesenchymal stromal cells-derived extracellular vesicles into knees of patients with osteoarthritis, comparing it to a control group who received saline injections.
- - In a triple-blind, randomized clinical trial involving 62 knees (31 patients), various measures, including pain and function assessments, were taken before and after the treatment, but no significant improvements were found between the two groups after 2 and 6 months.
- - The conclusion highlighted that while the injection was safe with no severe reactions observed, it did not lead to any clinical improvement in knee osteoarthritis symptoms or MRI findings.
Patellofemoral pain syndrome in children and adolescents: A cross-sectional study.
PLoS One
April 2024
Department of Physiotherapy, Postgraduate Program in Physiotherapy, Federal University of Rio Grande do Norte, UFRN, Natal, RN, Brazil.
Objectives: To assess the prevalence and associated factors of Patellofemoral Pain Syndrome (PFPS) in children and adolescents.
Method: A population-based cross-sectional study was conducted with children and adolescents aged 10 to 18 years, who presented a history of peripatellar and/or retropatellar pain, attending elementary or high school in urban public schools in Natal, Brazil. The sample size was calculated based on a minimum outcome prevalence of 22%.
Comminuted AO-C3 fractures of the patella: good outcome using anatomically contoured locking plate fixation.
Int Orthop
June 2022
Zentrum Für Unfallchirurgie Und Orthopädische Chirurgie, BG Unfallklinik Frankfurt Am Main, Friedberger Landstrasse 430, 60389, Frankfurt am Main, Germany.
Purpose: The treatment of comminuted patellar fractures remains a challenge for orthopedic surgeons. The aim of this study was to assess the clinical, functional, and radiological outcome after treatment of comminuted patellar fractures using an anatomically contoured plating system.
Methods: Between January 2015 and December 2019 (5 years), 29 patients with complex C3 fractures according to AO classification (18 female, 11 male; mean age: 53 years) were treated using an anatomically contoured plating system (patella SuturePlate™, Arthrex®, Naples, USA).
Patella fractures are rare injuries, accounting for 0.5 - 1.5% of all fractures, but they can lead to severe functional limitations if they do not heal properly.
