Summary
Irreducible knee dislocation, a rare injury, occurred during a softball game. Surgical intervention was necessary due to the medial collateral ligament and capsule locking within the intercondylar notch.
Area of Science:
- Orthopedic surgery
- Sports medicine
- Traumatology
Background:
- Irreducible knee dislocation is a rare and severe injury.
- Prompt diagnosis and management are crucial for optimal outcomes.
Observation:
- A case report of a 39-year-old U.S. Army noncommissioned officer with knee dislocation during a softball game.
- Arthroscopy revealed medial collateral ligament and capsule entrapment within the intercondylar notch.
- Magnetic resonance imaging confirmed the irreducible nature of the lesion.
Findings:
- Open reduction via arthrotomy was required for this irreducible knee dislocation.
- A staged posterior cruciate ligament reconstruction using a patellar tendon autograft was performed subsequently.
- The case highlights the diagnostic clinical and radiographic features of this unusual injury.
Implications:
- This case underscores the importance of recognizing irreducible knee dislocations.
- It emphasizes the need for timely surgical intervention in such complex knee injuries.
- Understanding the imaging features aids in diagnosing and managing these rare dislocations.
