Knee Dislocation in the Morbidly Obese Patient.

Area of Science:

• Orthopedics
• Trauma Surgery
• Obesity Medicine

Background:

• Knee dislocations are rare but increasingly reported in morbidly obese individuals.
• These injuries, termed "ultralow-velocity knee dislocations," often result from trivial events like ground-level falls.
• They are frequently underappreciated and misdiagnosed due to their low-velocity mechanism.

Purpose of the Study:

• To review the existing literature on knee dislocations in the morbidly obese population.
• To highlight the unique diagnostic and management challenges associated with these injuries.
• To discuss patient outcomes and the importance of physician awareness.

Main Methods:

• Literature review of studies on knee dislocations in morbidly obese patients.
• Analysis of diagnostic criteria and neurovascular assessment protocols.
• Evaluation of current management strategies and their associated complications.

Main Results:

• Morbidly obese patients have a high rate of associated neurovascular injury with knee dislocations.
• Timely diagnosis is critical to prevent limb-threatening complications, including amputation.
• Management remains controversial, with operative treatments carrying higher risks in this population.

Conclusions:

• Physicians must maintain a high suspicion for knee dislocation in morbidly obese patients presenting with knee pain after minor trauma.
• Prompt identification and management of vascular injuries are paramount.
• Familiarity with the unique challenges and risks is essential for optimal patient care and outcomes.
