Orthopaedics & Traumatology, Surgery & Research : OTSR
|July 21, 2026
Summary
Open access (OA) status and higher quality keywords are linked to increased citation rates in orthopaedic research. Improving article accessibility and keyword discoverability can enhance research impact.
Area of Science:
- Orthopaedic surgery and traumatology research.
- Bibliometrics and scientometrics.
Background:
- Citation counts are key metrics for scientific visibility and impact.
- Factors influencing citation rates, such as open access (OA) status and keyword characteristics, require further investigation.
- This study focuses on articles published in Orthopaedics & Traumatology: Surgery & Research (OTSR).
Purpose of the Study:
- To evaluate the impact of OA status on citation counts for OTSR articles.
- To assess how the number and quality of author-defined keywords affect citation rates.
- To identify modifiable factors that can improve the visibility of orthopaedic research.
Main Methods:
- A retrospective bibliometric analysis of 2,760 PubMed-indexed articles from OTSR (2016-2026).
- Data extracted included publication year, article type, OA status, and author-defined keywords.
- Citation counts were obtained from OpenAlex and Crossref, focusing on two-year post-publication citations. Keyword quality was assessed using frequentist and clinical relevance scores.
Main Results:
- Open access articles showed significantly higher two-year citation counts compared to non-OA articles.
- A higher number of author-defined keywords and better keyword quality (n-gram matches) were independently associated with increased citations.
- While clinical keyword relevance showed a positive trend, its association with citations was significant in univariable but not multivariable analysis.
Conclusions:
- Open access status and keyword quality are significant predictors of higher citation rates in orthopaedic research, even after accounting for citation maturation.
- Enhancing article accessibility through OA and optimizing keyword discoverability are potential strategies to boost research visibility.
- These findings suggest practical approaches for authors and journals to increase the impact of scientific publications.

01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
01:19Impact Loading
Impact loading occurs when a moving object collides with a stationary structure, such as a rod with a uniform cross-sectional area fixed at one end. Under these conditions, the rod absorbs the kinetic energy from the striking object, leading to deformation and subsequent stress development. As the rod returns to its original position and reaches maximum stress, the absorbed energy, initially manifested as kinetic energy, transforms entirely into strain energy.

01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

01:23Knee Joint
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

01:10Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts— that give the...
