The prevalence of the ALL was 61.7% (82% in North America, 64.9% in Europe, and 45.8% in Asia). The femoral insertion showed variability near the lateral femoral epicondyle and lateral collateral ligament, while the tibial insertion was midway between Gerdy's tubercle and fibular head. Histological analysis revealed 60% of studies identified ligamentous tissue similar to the anterior cruciate ligament.

The femoral insertion exhibited substantial variability at\/around the lateral femoral epicondyle and lateral collateral ligament, lacking consistency. The tibial insertion was more consistently described as being located about halfway between Gerdy's tubercle and the fibular head. Histological analysis showed that 60% of the included studies identified the ALL as containing ligament\u2010like or ligamentous tissue. The mean length of the ALL was 39.9 mm (range 31\u201059 mm), the mean width was 5.7 mm (range 2.2\u20109.0 mm), and the mean thickness was 1.5 mm (range 1.3\u20102.7 mm).
