Abstract PDF: Background
Patellar fractures are common injuries that require stable fixation to achieve optimal healing and restoration of knee function. This study aimed to analyze the mechanical properties of an anatomically precontoured patellar plate and to compare its maximum tensile load-bearing capacity with that of anterior tension wiring through cannulated screws and double-sided plating for the fixation of patellar fractures.
Methods
Artificial Sawbones with a standardized transverse fracture line were used to simulate patellar fractures. Each sawbone was attached to polyester bands, and this fracture model was applied consistently across all test samples. To evaluate mechanical properties of the anatomically precontoured patellar plate (model code 25-ANPA-209) made of ASTM F67 titanium, static tensile strength testing and dynamic tensile strength testing were performed, with seven samples prepared for each test. For comparison of maximum tensile load capacity among the anatomically precontoured patellar plate, anterior tension wiring through cannulated screws, and double-sided plating, five samples were prepared for each fixation group. All specimens were tested using a tension/compression testing machine.
Results
In the static tensile strength test, all seven samples exhibited a maximum tensile load capacity above 844 N without any fractures or failure points. The dynamic tensile strength test showed that all seven samples completed 10,000 cycles without deformation or damage to the anatomically precontoured patellar plate. When comparing maximum tensile load capacity, the anatomically precontoured patellar plate exhibited a significantly higher maximum tensile load-bearing capacity than anterior tension wiring through cannulated screws and double-sided plating.
Conclusions
The anatomically precontoured patellar plate demonstrated satisfactory mechanical performance, successfully meeting the criteria of both static and dynamic tensile strength testing, and showed superior maximum tensile load-bearing capacity compared with the other fixation methods evaluated. These findings suggest that the anatomically precontoured patellar plate may represent a reliable fixation option for the management of patellar fractures. Level of evidence: V.

Systematic Diagnosis and Treatment Principles for Acute Fracture-Related Infections: Jeong-Seok Choi, Jun-Hyeok Kwon, Seong-Hyun Kang, Yun-Ki Ryu, Won-Seok Choi, Jong-Keon Oh, Jae-Woo Cho; J Korean Fract Soc 2023;36(4):148-161.

Abstract PDF: Acute fracture-related infection (FRI) is a common and serious complication of fracture treatment. The clinical symptoms of the patient and the results of the serological, radiological, and histopathologi-cal examinations can be divided into ‘Confirmatory’ criteria and ‘Suggestive’ criteria, allowing for the diagnosis of FRI. Treatment principles can be broadly categorized into (1) the DAIR (Debridement, Antimicrobial therapy, Implant Retention) method and (2) the staged reconstruction method. The choice of treatment depends on factors such as the time elapsed after infection, stability of the internal fixation device, reduction status, host physiology, and virulence of the pathogens. Thorough surgical debridement and irrigation, ensuring stability at the fracture site, reconstruction of bone defects, and appropriate soft tissue coverage, along with antibiotic therapy, are essential to suppress or eradicate the infection. The restoration of limb function should be promoted through proper soft tissue coverage and bone union at the fracture site.
