Increased internal tibiofemoral rotation is associated with anterolateral ligament injury and high-grade pivot-shift in ACL-injured patients.
Purpose: To evaluate whether tibiofemoral rotation is associated with a concurrent anterolateral ligament (ALL) injury and pivot-shift grading in patients with a primary anterior cruciate ligament (ACL) tear.
Methods: In this multicenter cross-sectional study constituting a secondary analysis of previous studies, medical records and magnetic resonance imaging (MRI) scans of patients with unilateral primary ACL injury were reviewed. Demographics and pivot-shift grading were collected. ALL was identified on MRI coronal images and categorized as intact or injured. Tibiofemoral rotation angle (TFA) was measured on axial MRI. Optimal TFA cut-off associated with ALL injury was identified by a receiver operating characteristic (ROC) curve.
Results: Of 206 included patients, 152 (73.8%) exhibited signs of ALL injury. Pivot-shift tests were predominantly graded as 2 (71.4%), and notably, all Grade 3 pivot-shift assessments were associated with ALL injury. Mean TFA was significantly higher in cases with ALL injury (5.2 ± 3.6°) compared to intact ALL cases (2.7 ± 3.5°; p < 0.001). A positive correlation was observed between pivot-shift grading and TFA (r = 0.204, p = 0.003). Optimal TFA cut-off value, based on the absolute measurement, for predicting ALL injury was 2.5° (sensitivity: 0.77; specificity: 0.55). Patients with TFA ≥ 2.5° had a significantly higher risk of ALL injury (odds ratio: 3.34, 95% confidence interval [CI]: 1.74-6.42, p < 0.001); when combined with pivot-shift Grade 2 or 3, this risk substantially increased to 13.68 (95% CI: 6.29-29.84, p < 0.001).
Conclusion: Higher TFA was associated with an increased prevalence of ALL injuries and a high-grade pivot-shift in ACL-deficient patients. Patients with a TFA ≥ 2.5° showed a threefold higher likelihood of ALL injuries, and this risk further escalated with a higher-grade pivot-shift.
期刊介绍：
Few other areas of orthopedic surgery and traumatology have undergone such a dramatic evolution in the last 10 years as knee surgery, arthroscopy and sports traumatology. Ranked among the top 33% of journals in both Orthopedics and Sports Sciences, the goal of this European journal is to publish papers about innovative knee surgery, sports trauma surgery and arthroscopy. Each issue features a series of peer-reviewed articles that deal with diagnosis and management and with basic research. Each issue also contains at least one review article about an important clinical problem. Case presentations or short notes about technical innovations are also accepted for publication.
The articles cover all aspects of knee surgery and all types of sports trauma; in addition, epidemiology, diagnosis, treatment and prevention, and all types of arthroscopy (not only the knee but also the shoulder, elbow, wrist, hip, ankle, etc.) are addressed. Articles on new diagnostic techniques such as MRI and ultrasound and high-quality articles about the biomechanics of joints, muscles and tendons are included. Although this is largely a clinical journal, it is also open to basic research with clinical relevance.
Because the journal is supported by a distinguished European Editorial Board, assisted by an international Advisory Board, you can be assured that the journal maintains the highest standards.
Official Clinical Journal of the European Society of Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA).
