S82.123

Clinical Causes: Falls onto the knee or leg from a height Motor vehicle accidents involving direct impact to the knee Sports injuries, particularly those involving twisting or direct blows to the knee Trauma from heavy objects falling onto the leg Twisting injuries during activities like skiing, skateboarding, or gymnastics

Key Symptoms: Severe pain around the knee or upper leg Swelling and tenderness in the affected area Deformity or abnormal appearance of the knee Inability or difficulty bearing weight on the leg Bruising around the knee Limited range of motion in the knee joint

Diagnosis Path: Diagnosis typically involves a thorough physical examination and imaging studies. X-rays are the primary tool used to confirm the presence of a fracture and assess the extent of displacement. In some cases, additional imaging such as MRI or CT scans may be recommended to evaluate soft tissue injuries or complex fracture patterns. The healthcare provider will also examine the neurovascular status of the limb to ensure blood flow and nerve function are intact.

Treatment Protocols: Treatment options depend on the severity and displacement of the fracture. Common approaches include: - **Immobilization:** For minimally displaced fractures, a cast or immobilizer may be used to keep the bone in place while healing. - **Reduction:** Displaced fractures often require a procedure to realign the bone fragments, which can be done manually (closed reduction) or surgically (open reduction). - **Fixation:** Surgical intervention may involve the use of pins, screws, or plates to stabilize the fracture and promote proper healing. - **Rehabilitation:** After initial treatment, physical therapy is typically necessary to restore strength, flexibility, and mobility in the knee. Recovery time varies depending on the age, health status, and severity of the injury, but it typically involves several weeks to months of healing and rehabilitation.
