Short-term Clinical Outcome of Surgically Managed Acute Floating Knee Injury.

Area of Science:

• Orthopedic Surgery
• Trauma Care
• Biomechanics

Background:

• Floating knee injuries, involving ipsilateral femur and tibia fractures, are severe high-velocity trauma consequences.
• These injuries present significant morbidity and potential life-threatening complications.

Purpose of the Study:

• To evaluate early clinical outcomes of acute floating knee injuries.
• To identify and analyze treatment-related complications.

Main Methods:

• A cohort of 15 patients with acute floating knee injuries was studied over 18 months.
• Data collected included demographics, fracture type, injury mechanism, surgical procedures, associated injuries, and complications.
• Clinical outcomes were assessed using Karlström and Orleud's criteria.

Main Results:

• 66.7% of patients had Fraser's type I fractures.
• Mean bone union times were 7.79 months for the femur and 8.21 months for the tibia, with a mean weight-bearing time of 9.71 months.
• Knee haemarthrosis was the most common early complication, and delayed union was the most frequent late complication. Fraser's type I fractures showed the highest mean range of motion (115.50°).

Conclusions:

• Floating knee injury is a rare but severe condition with substantial morbidity.
• An individualized management strategy is crucial for achieving satisfactory patient outcomes.
