# Knee Osteoarthritis Severity Grading Using Optimized Deep Learning and LLM-Driven Intelligent AI on Computationally Limited Systems Source: [https://arxiv.org/abs/2605.05731](https://arxiv.org/abs/2605.05731) [View PDF](https://arxiv.org/pdf/2605.05731) > Abstract:Knee osteoarthritis \(KOA\) is among the musculoskeletal disorders that considerably restrict joint mobility, cause severe chronic pain and impact negatively on quality life\. It is one of the persistent health issues worldwide\. Generally, subjectivity and inter\-observer variability undermine conventional practices and evaluation process that are adopted to address such health issues\. Hence precise and timely diagnosis would be one of the effective ways for the assessment of its severity\. This paper proposes an automated diagnostic approach for severity grading of KOA by blending a deep learning convolutional neural network \(CNN\) with a device\-based inference platform powered by TensorFlow Lite\. It proposes a model based on the ResNet\-18 convolutional neural network\. The designed model is trained on publicly available database\. Through a transfer learning approach obtained knee images are first classified into five Kellgren\-Lawrence \(KL\) grades\. Further the developed model is optimised\. During the training of the model test accuracy of 94\.48% with stable convergence has been achieved\. Subsequently the optimised model transformed into a lightweight TensorFlow Lite format, facilitating seamless deployment on resource\-constrained devices\. The designed model is capable enough to operate in the environment having no continuous internet connectivity\. Also, an auxiliary Large Language Model \(Gemini\-2\.0\-flash\) is applied to generate structured interpretive findings like potential symptoms, risk factors, and preventive majors etc\. The LLM component functions as interface without influencing the classification process\. The proposed model articulates the feasibility of an on\-device, interpretable decision\-support tools for early diagnosis and improve accessibility to Artificial Intelligence \(AI\)\-assisted knee screening tool\. ## Submission history From: Dayam Nadeem \[[view email](https://arxiv.org/show-email/fd4be269/2605.05731)\] **\[v1\]**Thu, 7 May 2026 06:24:04 UTC \(1,471 KB\)
