This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,423.

Summary of the Inventive Concept

A next-generation acetabular cup system that enables real-time customization of the hip joint replacement procedure through modular, interchangeable liners with distinct offset axes, universal adapters, and advanced sensor technologies.

Background and Problem Solved

The original off-center liner for acetabular cup patent addressed the need for improved stability and performance in hip joint replacement procedures. However, this new inventive concept tackles the limitations of the original patent by introducing a modular system that allows for real-time customization, minimizing the risk of post-operative complications and enabling surgeons to adapt to unique patient anatomies.

Detailed Description of the Inventive Concept

The modular acetabular cup system comprises interchangeable liners with distinct offset axes, secured to the acetabular cup via a universal adapter. This design enables real-time customization of the hip joint replacement procedure, allowing surgeons to select the optimal liner offset axis and acetabular cup orientation for each patient. The system can be integrated with advanced sensor technologies, machine learning algorithms, and shape-memory alloys to further enhance its performance and adaptability.

Novelty and Inventive Step

The new claims introduce a paradigm shift in acetabular cup design by incorporating modular, interchangeable liners with distinct offset axes, universal adapters, and advanced sensor technologies. This innovative approach enables real-time customization, surpassing the limitations of the original off-center liner patent and providing a more ambitious and forward-thinking solution.

Alternative Embodiments and Variations

Alternative embodiments of the modular acetabular cup system could include variations in liner design, such as adjustable offset axes or adaptive materials, as well as different sensor technologies and machine learning algorithms. Additionally, the system could be adapted for use in other joint replacement procedures, such as knee or shoulder replacements.

Potential Commercial Applications and Market

The modular acetabular cup system has significant commercial potential in the orthopedic industry, particularly in the hip joint replacement market. The system's ability to enable real-time customization and minimize post-operative complications could lead to increased adoption and market share. Target industries include orthopedic device manufacturers, hospitals, and surgical centers.
