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. 11,857,576.

Summary of the Inventive Concept

The inventive concept integrates patented cartilage repair compositions and methods with cutting-edge technologies like AI, IoT, blockchain, and nanomaterials to create personalized, efficient, and secure treatment systems for chondral and osteochondral lesions.

Background and Problem Solved

Chondral and osteochondral lesions are common injuries that can lead to osteoarthritis, but current treatments have limitations. The original patent addressed this issue with compositions and methods for repairing cartilage defects. However, the new inventive concept tackles the problem by leveraging synergistic combinations of technologies to enhance the effectiveness, personalization, and security of cartilage repair treatments.

Detailed Description of the Inventive Concept

The inventive concept encompasses four main systems: (1) a machine learning-based system that predicts optimal cell density for personalized treatment; (2) an IoT-enabled system that monitors tissue regeneration during treatment; (3) a blockchain-based system that securely stores patient data and facilitates personalized cartilage repair using 3D-printed scaffolds; and (4) an AI-powered system that characterizes cell samples and optimizes cartilage matrix manufacturing. Additionally, the inventive concept incorporates nanomaterial-based delivery systems for sustained release of growth factors. These synergistic combinations enable more effective, efficient, and personalized cartilage repair treatments.

Novelty and Inventive Step

The new claims introduce non-obvious combinations of technologies that significantly improve the effectiveness and personalization of cartilage repair treatments. The integration of machine learning, IoT, blockchain, and nanomaterials with the original patent's compositions and methods constitutes a novel and inventive step forward in the field of cartilage repair.
