S83.262
Peripheral tear of lateral meniscus, current injury, left knee
Clinical Classification Guidelines
Medical Intelligence & Overview
A lateral meniscus tear in the left knee is a common injury involving a tear in the cartilage located on the outer side of the knee joint. The menisci serve as shock absorbers between the thighbone (femur) and the shinbone (tibia), contributing to joint stability and load distribution. When the lateral meniscus sustains a tear, it can cause pain, swelling, and limited mobility, affecting daily activities and sports participation. Recognizing this injury promptly can help in managing symptoms effectively and in planning appropriate treatment strategies.
Causes & Symptoms
Clinical Causes: Sudden twisting or pivoting motions, especially when the foot is planted and the knee is bent Direct blow or impact to the knee during sports or accidents Degenerative changes due to aging, which weaken the meniscus tissue over time Repetitive knee stress from activities like squatting, kneeling, or heavy lifting Previous knee injuries or surgeries that compromise joint stability
Key Symptoms: Pain on the outer (lateral) side of the knee, especially during movement or twisting Swelling or stiffness around the knee joint Difficulty bending or straightening the knee fully A sensation of the knee locking or catching during movement Feeling of instability or the knee giving way Tenderness upon pressing on the outer knee area
Diagnostic & Treatment
Diagnosis Path: Magnetic Resonance Imaging (MRI): The most sensitive test for visualizing meniscal tears and associated injuries. X-rays: While it does not show soft tissues like the meniscus, X-rays can rule out other causes of knee pain such as fractures or arthritis. Arthroscopy: A minimally invasive procedure where a small camera is inserted into the knee joint, allowing for direct visualization and assessment of the meniscal tear.
Treatment Protocols: Meniscectomy: Removal of the torn portion of the meniscus, typically performed arthroscopically Meniscus repair: Stitching the torn edges to preserve as much of the meniscus as possible, often preferred for tears in certain locations and for younger patients
