M23.339
Other meniscus derangements, other medial meniscus, unspecified knee
Clinical Classification Guidelines
Medical Intelligence & Overview
Other meniscus derangements classified under ICD-10 code M23.339 involve injuries or abnormalities affecting the medial meniscus of the knee that do not fall under more specific categories. The meniscus is a crucial cartilage structure that acts as a cushion between the thighbone (femur) and shinbone (tibia). Proper functioning of the menisci is vital for knee stability, load distribution, and smooth movement. When the medial meniscus experiences derangement—such as tears, displacements, or other irregularities—it can interfere with normal knee function, cause pain, and may lead to further joint issues if not addressed appropriately.
Causes & Symptoms
Clinical Causes: Traumatic injuries, such as from sports activities involving twists or sudden turns Degenerative changes related to aging that weaken the meniscal tissue Repetitive stress or overuse from activities requiring frequent knee bending or pivoting Sudden impact or direct blow to the knee Poor biomechanics or alignment leading to uneven load distribution
Key Symptoms: Pain localized along the inner aspect of the knee Swelling or tenderness around the joint Limited range of motion, especially when trying to fully bend or straighten the knee A sensation of the knee locking or catching during movement Feeling of instability or giving way, particularly during weight-bearing activities Discomfort when twisting or rotating the knee
Diagnostic & Treatment
Diagnosis Path: To accurately diagnose other meniscus derangements, healthcare providers typically employ a combination of medical history assessment, physical examination, and imaging studies. These may include:
Treatment Protocols: Management of other meniscus derangements aims to reduce symptoms, promote healing, and restore knee function. Treatment options may involve:
