Lateral marginal fractures of the patella and patellofemoral pain: Jae-Ang Sim, Chul-Ho Kim, Ji Wan Kim; J Musculoskelet Trauma 2025;38(3):152-159. Published online July 22, 2025; DOI: https://doi.org/10.12671/jmt.2025.00171

Abstract PDF: Background
This study investigated the characteristics of lateral marginal fractures of the patella and evaluated the clinical outcomes.
Methods
We retrospectively reviewed all patients with lateral marginal fractures of the patella, defined as a vertical fracture line within 15 mm of the lateral patellar border, from 2008 to 2020. In total, 41 patients were included. Patient characteristics, radiologic findings, and clinical outcomes, including the Lysholm score at 1 year postoperation, were evaluated.
Results
The injury mechanisms were direct in 34 cases and indirect in seven. Furthermore, 85% of patients had a skyline view of the patella at the initial visit, and one medial subluxation of the patella was found. Forty of the 41 patients underwent surgery. Anatomical and nonanatomical (>1-mm displacement or excision) reductions were carried out in 36 cases (88%) and five cases (12%), respectively. The average Lysholm score was 89.1 (range, 67–99). The nonanatomical reduction group had a poorer functional score (79.8 vs. 90.4; P=0.010). Lateral patellar compression syndrome occurred in two patients with nonanatomical reduction.
Conclusions
Lateral marginal fractures of the patella affected patellofemoral stability. Anatomical reduction showed good functional outcomes, while nonanatomical reduction was associated with patellofemoral stability and pain. Therefore, surgeons should perform anatomical reduction with any appropriate fixation method. Level of Evidence: IV

Tension Band Wiring Technique for Distal Radius Fracture with a Volar Articular Marginal Fragment: Technical Note: Neunghan Jeon, Jong Keon Oh, Jae Woo Cho, Youngwoo Kim; J Korean Fract Soc 2020;33(1):38-42. Published online January 31, 2020; DOI: https://doi.org/10.12671/jkfs.2020.33.1.38

Abstract PDF

Most distal radius fractures are currently being treated with anterior plating using anatomical precontoured locking compression plates via the anterior approach. However, it is difficult to fix the volar articular marginal fragment because these anatomical plates should be placed proximally to the watershed line. There were just a few methods of fixation for this fragment on medical literature. Herein, we introduced a tension band wiring technique for fixation of a volar articular marginal fragment in the distal radius.
