M23.261
Derangement of other lateral meniscus due to old tear or injury, right knee
Clinical Classification Guidelines
Medical Intelligence & Overview
A derangement of the lateral meniscus in the right knee, classified under ICD-10 code M23.261, refers to a disruption or abnormal movement of the lateral meniscus caused by a previous tear or injury. The menisci are two crescent-shaped cartilage pieces that act as shock absorbers between the thigh bone (femur) and shinbone (tibia). When the lateral meniscus becomes deranged, it can lead to pain, swelling, and difficulty with knee movement, affecting daily activities and overall mobility.
Causes & Symptoms
Clinical Causes: Previous knee injury or trauma involving the lateral meniscus Degenerative changes due to aging or wear and tear Sudden twisting or pivoting movements during sports or physical activities Repeated stress or overuse of the knee joint Inadequate healing of a prior meniscal tear
Key Symptoms: Knee pain, especially along the outer side Swelling and stiffness in the knee joint A sensation of catching, locking, or giving way during movement Reduced range of motion or difficulty fully extending or bending the knee Tenderness when touching the lateral part of the knee Instability or a feeling that the knee may buckle
Diagnostic & Treatment
Diagnosis Path: Diagnosis of a deranged lateral meniscus typically involves a combination of medical history review, physical examination, and imaging tests. Healthcare providers may perform specific knee tests to assess stability, range of motion, and pain points. Magnetic Resonance Imaging (MRI) is the most common and effective method for visualizing meniscal injuries, allowing for detailed assessment of the cartilage and surrounding structures. X-rays may be utilized to rule out other causes of knee problems, such as fractures or arthritis.
Treatment Protocols: Treatment approaches for a deranged lateral meniscus due to old tear or injury depend on the severity and the specific circumstances. Options may include:
