S82.042

Clinical Causes: High-impact falls directly onto the front of the knee Sports injuries involving direct blows or jumping accidents Traffic accidents involving knee trauma Severe twisting injuries to the knee Crushing injuries from heavy objects

Key Symptoms: Intense pain in the front of the knee Swelling and bruising around the kneecap Inability to straighten the knee or bear weight Visible deformity or misalignment of the kneecap Tenderness when touching the kneecap A grinding or clicking sensation during movement

Diagnosis Path: Diagnosing a displaced comminuted fracture of the left patella involves a combination of physical examination and imaging tests. A healthcare provider will assess pain levels, swelling, and deformity, and check for instability or difficulty in movement. Imaging studies such as X-rays are essential to determine the fracture pattern, the degree of displacement, and the number of bone fragments. Sometimes, additional imaging like MRI or CT scans may be used for detailed visualization of complex fractures.

Treatment Protocols: Treatment of a displaced comminuted patella fracture often requires surgical intervention to realign the bone fragments and stabilize the knee. Common procedures include open reduction and internal fixation (ORIF) with pins, screws, or wires to hold the fragments together. Post-surgery, immobilization of the knee with a cast or brace is typically necessary for several weeks. Rehabilitation involving physical therapy is critical to restore knee strength and mobility. Non-surgical options are limited and usually reserved for minimally displaced fractures or patients who are not surgical candidates. During recovery, pain management, elevation, and specific exercises guided by a healthcare professional support healing and prevent complications such as joint stiffness or muscle atrophy. In some cases, additional treatments may include blood clot prevention measures or addressing associated injuries.
