S83.016

Clinical Causes: Trauma from direct blows to the front of the knee Sudden twisting or pivoting motion during physical activity Falls that impact the knee Sports injuries, especially in activities involving quick turns or jumps Pre-existing ligament or cartilage injuries that weaken knee stability

Key Symptoms: Sudden, sharp pain on the outer side of the knee Visible deformity or displaced kneecap Swelling around the knee joint Difficulty in straightening or bending the knee A sensation of instability or the knee giving way Limited range of motion in the affected knee Tenderness over the kneecap

Diagnosis Path: To diagnose a lateral dislocation of the patella, healthcare providers typically perform a physical examination to assess knee stability, deformity, and pain points. Imaging studies such as X-rays are essential to confirm the dislocation, determine whether there are any associated injuries like fractures, and evaluate the position of the patella. In some cases, MRI scans might be used to assess soft tissue damage, such as ligament or cartilage injuries.

Treatment Protocols: Immediate reduction: Manual repositioning of the patella, usually performed by a healthcare professional after ensuring appropriate pain management. Immobilization: Using a knee brace or splint to prevent further displacement and support healing. Rest and ice: To reduce swelling and pain during the initial phase. Pain management: Over-the-counter analgesics or prescribed medications. Physical therapy: Focused on strengthening the muscles around the knee, improving stability, and preventing future dislocations. Surgical intervention: In recurrent or severe cases, procedures like medial patellofemoral ligament reconstruction or realignment surgeries may be recommended to correct underlying instability and prevent future dislocations. Rehabilitation: Gradual return to activities with supervised exercises to restore knee strength and function.
