Abstract

Background

The oblique popliteal ligament (OPL) plays a crucial role in knee stability, yet its anatomical variations are not fully understood. This study aimed to provide a comprehensive morphometric and morphological analysis of the OPL in the South Indian population.

Methods

Twenty cadaveric knee specimens were dissected and examined. The length and width of the OPL were measured using digital calipers. Morphological characteristics, including shape and attachment patterns, were observed and classified.

Results

The mean length of the OPL was 28.9 ± 3.7 mm, with a width of 17.5 ± 4.3 mm at the origin and 18.3 ± 4.4 mm at the midpoint. Three main types of OPL were identified: Type 1 (45 %) with an accessory upper band, Type 2 (30 %) with a broad medial attachment, and Type 4 (25 %) with a fan-like appearance. Five shape variations were observed: band shape (30 %), trident shape (25 %), complex shape (20 %), Z-shape (15 %), and Y-shape (10 %).

Conclusion

This study reveals significant variability in OPL morphology and dimensions. These findings have important implications for understanding knee biomechanics, improving surgical techniques, and enhancing the interpretation of imaging studies of the posterior knee.

期刊介绍： Translational Research in Anatomy is an international peer-reviewed and open access journal that publishes high-quality original papers. Focusing on translational research, the journal aims to disseminate the knowledge that is gained in the basic science of anatomy and to apply it to the diagnosis and treatment of human pathology in order to improve individual patient well-being. Topics published in Translational Research in Anatomy include anatomy in all of its aspects, especially those that have application to other scientific disciplines including the health sciences: • gross anatomy • neuroanatomy • histology • immunohistochemistry • comparative anatomy • embryology • molecular biology • microscopic anatomy • forensics • imaging/radiology • medical education Priority will be given to studies that clearly articulate their relevance to the broader aspects of anatomy and how they can impact patient care.Strengthening the ties between morphological research and medicine will foster collaboration between anatomists and physicians. Therefore, Translational Research in Anatomy will serve as a platform for communication and understanding between the disciplines of anatomy and medicine and will aid in the dissemination of anatomical research. The journal accepts the following article types: 1. Review articles 2. Original research papers 3. New state-of-the-art methods of research in the field of anatomy including imaging, dissection methods, medical devices and quantitation 4. Education papers (teaching technologies/methods in medical education in anatomy) 5. Commentaries 6. Letters to the Editor 7. Selected conference papers 8. Case Reports
