Online Journal «ABOUT ROUND LIGAMENT OF FEMUR», December 2025

 

The journal is dedicated to the
ligamentum capitis femoris (LCF)
and related topics

 

About the Journal »»»                                                                             .


The online journal «About Round Ligament of Femur» was created based on the scientific blog of the same name. The resource is the English-language part of the project: 


Updates: As new materials are prepared.
Mission: Popularization and preservation of knowledge about LCF, as well as promoting its practical application.
Main goal: Improvement of diagnosis, treatment, and prevention of injuries and diseases of the hip joint.
Publisher: Arkhipov S.V., independent researcher, PhD, orthopedic surgeon.
Reviewers:
  1. Grok, an artificial intelligence developed by xAI.
  2. ChatGPT, a language model trained by OpenAI to assist with text analysis and editing.

  The first-principle thinking: the reaction force of the artificial ligaments in the hip prosthesis moves the pelvis when the muscles relax; this can be used for robot walking.

  Hip replacements are currently ineffective because they ignore the physics of ligament tension. A prosthesis with ligaments restores natural kinematics and eliminates dislocation in humans; it would be beneficial for Optimus & quadruped robots. Designed for @elonmusk #Optimus #TeslaBot First principle: A joint isn't just a pivot; it's a dynamic tension system. By replacing rigid limits with elastic stabilizers, we solve the stability-mobility paradox. This technology isn't just for humans; it's the future of resilient joints for robots.

Arkhipov SV. Improving Postoperative Comfort

  Arkhipov SV. Improving Postoperative Comfort and Increasing the Reliability of Hip Prostheses by Supplementing with Artificial Ligaments: Proof of Concept and Prototype Demonstration. DOI: 10.13140/RG.2.2.15175.15524 The author invites laboratories and companies to collaborate on the development of prostheses with artificial ligaments. Updated version of the article: https://roundligament.blogspot.com/2025/12/improving-postoperative-comfort.html   Abstract . The principle of operation of an experimental total hip endoprosthesis augmented with ligament analogs has been demonstrated in single-leg vertical stances and at the mid-stance phase of the single-support period of gait. The experiments were conducted on a specially designed mechatronic testing rig. The concept of the important role of the ligamentous apparatus is further illustrated by a set of demonstrative mechanical models. The data obtained from the experiments enabled the development of a prototype total h...
