What is a common indication for surgical intervention in cases of quadriceps tendon rupture?

• A. Persistent swelling without pain
• B. Inability to actively extend the knee
• C. Limited range of motion in the hip
• D. Severe pain during strict bed rest

Answer: (B)

The indication for surgical intervention in cases of quadriceps tendon rupture is primarily the inability to actively extend the knee. This inability results from the disruption of the quadriceps mechanism, which is crucial for knee extension. When the quadriceps tendon is ruptured, the force that allows the quadriceps muscle to pull on the patella and extend the knee joint is compromised. This leads to significant functional impairment, as patients are unable to perform essential movements such as walking, climbing stairs, or rising from a seated position.

Surgery is typically recommended to restore the integrity of the tendon, allowing for proper functioning of the knee joint and return to normal activities. Timely surgical repair is important to optimize outcomes, as prolonged inability to extend the knee can lead to complications such as muscle atrophy and joint stiffness.

Other indications, like persistent swelling without pain, do not directly indicate the need for surgical intervention in a quadriceps tendon rupture. Similarly, limited range of motion in the hip is not a direct consequence of the quadriceps injury, and severe pain during strict bed rest could arise from various conditions and may not necessitate surgical intervention.
