Management of the Knee Extension Deficit after Acute Trauma

Area of Science:

• Orthopedics
• Sports Medicine
• Rehabilitation Science

Background:

• Arthrogenic muscle inhibition (AMI) is a common cause of knee extension deficit after acute knee trauma.
• AMI is a functional deficit, distinct from mechanical blocks, that can negatively impact outcomes following knee surgery.
• Early recognition and diagnosis of AMI are crucial for effective patient management.

Observation:

• A 25-year-old male patient presented with a significant right knee extension deficit post-trauma.
• The deficit was diagnosed as arthrogenic muscle inhibition, not intra-articular pathology.
• The patient experienced functional limitations due to the loss of knee extension.

Findings:

• The patient underwent a tailored rehabilitation program.
• The rehabilitation technique led to significant functional gains in the quadriceps muscle.
• Full restoration of knee extension was achieved.

Implications:

• Rehabilitation is an effective treatment for arthrogenic muscle inhibition.
• Addressing AMI can improve functional outcomes after knee trauma and surgery.
• This case highlights the importance of diagnosing and treating functional neuromuscular deficits.
