Abstract
Background: A case series demonstrating functional outcomes of 36 patients 2 years following anterior cruciate ligament (ACL) reconstruction utilizing hamstring autografts is presented here. We employed a quadruple bundle technique with cortical endobutton fixation. Materials and Methods: The methods of evaluation comprised of the 2000 International Knee Documentation Committee (IKDC) knee forms, clinical hamstring and quadriceps muscle strength testing in guidance with the Medical Research Council (MRC) grading, single leg triple hop assessment for distance, and the 'Aircast Rolimeter' arthrometer for objective joint laxity. Results: Mean IKDC score was 84.05 ± 14.37. A clinical final evaluation of normal or nearly normal was obtained by 97.2% (35/36) the participants. Passive motion deficit measured clinically using a goniometer was also found to be normal or nearly normal in 97.2% (35/36). One hundred percent of patients had normal or near normal grades for clinical manual knee ligament tests, 94.4% (34/36) patients had normal or near normal compartmental findings, and 100% of patients had normal or near normal harvest site findings. Hamstring muscle strength of the operated knee was clinically assessed to be 5/5 in 86.11% of candidates, while quadriceps muscle strength measured 5/5 in 100% of the subjects. The triple leg hop for distance demonstrated optimal performance with a limb symmetry index of 95.3 ± 13.3%. Arthrometric measurements revealed a mean side to side difference of + 0.70 ± 1.78 mm with Lachman's test and + 0.67 ± 1.43 mm with the anterior drawer test between the operated knee and the normal contralateral knee. Conclusion: We conclude that at 18 months following ACL reconstruction with hamstring auto grafts, our subject group displayed exceptionally satisfactory functional outcomes.
