Extra-articular stabilization of the knee a.m. Losee

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomechanics

Background:

• Chronic anterior cruciate ligament (ACL) insufficiency can lead to disabling knee instability.
• Surgical reconstruction is often necessary to restore knee function.
• The Losee technique is one surgical approach for ACL reconstruction.

Purpose of the Study:

• To evaluate the clinical outcomes of the Losee surgical technique for chronic anterior cruciate insufficiency.
• To assess the relationship between anterolateral stability and functional knee scores after surgery.

Main Methods:

• A cohort of 34 patients underwent the Losee procedure for chronic anterior cruciate insufficiency between 1979-1981.
• Twenty-nine patients were available for follow-up at an average of 2 years post-surgery.
• Clinical assessments included the Slocum test for stability and the Lysholm knee score for function.

Main Results:

• At follow-up, 20 out of 29 patients demonstrated a negative Slocum test, indicating good stability.
• Twenty-one patients achieved a Lysholm knee score greater than 77, classified as good or excellent outcomes.
• A significant correlation was found between anterolateral stability and higher Lysholm knee scores.

Conclusions:

• The Losee surgical technique appears effective in managing chronic anterior cruciate insufficiency.
• Restoration of anterolateral stability is a key factor in achieving favorable functional outcomes and patient satisfaction.
