Low early fixation failure rates with variable-angle locking plate fixation of AO/OTA 34 C patella fractures: a retrospective cohort study

European Journal of Orthopaedic Surgery & Traumatology | 2026 | Benyamin Dadpey, Kevin Zhu, Claire Bonnyman, Hevatib Mehmood

Abstract Purpose To determine the fixation failure rate of the variable-angle (VA) locking patella plate and to evaluate whether supplemental augmentation reduced the risk of fixation failure. Methods A retrospective comparative cohort study was performed at a Level I trauma center between January 2021 and June 2025. Adult patients with OTA/AO 34 C patella fractures treated wit...

High Failure Rates in Comminuted Patella Fractures (AO/OTA 34-C3) Fixed With an Isolated, New Patella-Specific 2.7-mm Variable-Angle Locking Plate

Journal of Orthopaedic Trauma | 2025 | Wayne Hoskins, Rown Parola, Charles Gusho, Jaime L. Bellamy

OBJECTIVES: To compare the outcomes of comminuted patella fractures fixed with a new patella-specific 2.7-mm variable-angle (VA) locking plate in isolation versus when augmentation of fracture fixation is applied with the plate. METHODS: Design: Retrospective. Setting: Academic Level I Trauma Center. Patient Selection Criteria: All acute comminuted patella fractures (AO/OTA 34-...

A double-suture cerclage reduction technique with Nice knots for comminuted patella fractures (AO/OTA 34-C3)

Journal of Orthopaedic Surgery and Research | 2023 | Yanchun Gao, Xiaojun Han, Bin Zhou, Shichang Zhao

Abstract Background Comminuted patella fractures place high demands on surgeons’ surgical skills. We used a double-suture cerclage reduction with Nice knots as an intra-operative reduction technique to displaced comminuted patella fractures. Methods Patients were divided into two groups by whether or not an intra-operative suture cerclage reduction technique was used. Fragments...

Cephalomedullary nailing for reverse oblique intertrochanteric fractures 31A3 (AO/OTA)

Orthopedic Reviews | 2022 | Emanuela Marsillo, Andrea Pintore, Giovanni Asparago, Francesco Oliva

Introduction Reverse oblique intertrochanteric fractures are classified by the Orthopaedic Trauma Association [OTA]/[AO] as 31A3, and account for up to one-third of all hip fractures, and 2–23% of all trochanteric fractures. The treatment of choice of those fractures is intramedullary nailing as it decreases soft tissue damage and permits early weight bearing. Material and meth...

Fracture Patterns and Comminution Zones in OTA/AO 34C Type Patellar Fractures

Journal of Orthopaedic Trauma | 2020 | Abdulhamit Misir, Turan Bilge Kizkapan, Erdal Uzun, Sinan Oguzkaya

Objectives: To characterize the fracture patterns and comminution zones for complete articular (OTA/AO 34C type) patellar fractures, using a computed tomography mapping technique. Methods: Eighty-three OTA/AO 34C type patellar fractures were included. Images of patellar fractures were superimposed on a coronal template of the patella, created from a healthy right knee, to ident...

The three‐dimensional tracking pattern of the human patella

Journal of Orthopaedic Research | 1990 | A. van Kampen, R. Huiskes

AbstractA study was undertaken to provide data on the three‐dimensional tracking pattern of the patella, relative to the femur, in human knee‐joint specimens. For this purpose, a highly accurate roentgen stereophotogrammetric analysis (RSA) method was applied. The three‐dimensional motion patterns of the tibia and the patella were measured and represented in terms of three tran...

The additional iron cable fixation between proximal patella and tibial tuberosity to treat AO/OTA 34C3 patellar fracture

Journal unavailable | Dongzheng Zhang, Yong Shen

Abstract Background:It is very difficult to deal with AO/OTA 34C3 patellar fracture. Although the modified Kirschner wire tension band, the cerclage and plate has been proposed to treat it, the result is not very good. We found that if the fixation was not firm enough after the modified Kirschner wire tension band with or without the cerclage had been carried out, the additiona...
