Purpose: To compare the clinical results after reconstruction of the anterior cruciate ligament (ACL) between above the 50 years old patients and below the 50 years old patients retrospectively.
Materials and Methods: The results obtained 18 patients above 50 years old (mean age 55.1) and 198 patients below 50 years old (mean age 31.2) who underwent reconstruction of the ACL between July 2004 and April 2008. Clinical evaluation was performed with the International Knee Documentation Committee (IKDC) and Lysholm knee score scale. Anterior displacement of knee was measured by KT-2000 arthrometer.
Results: Lysholm scores improved from 69.5 to 93.6 in patients above 50 years old, from 69.0 to 92.6 in patients below 50 years old (p<0.05). According to IKDC score, results more than nearly normal was 83% (15 cases) in patients above 50 years old, 86% (170 cases) in patients below 50 years (p<0.05). The mean difference of anterior displacement measured by KT-2000 was decreased from 7.4 mm to 2.2 mm in patients above 50 years old, from 7.1 mm to 2.0 mm in patients below 50 years old (p<0.05).
Conclusion: There was no significant difference between the patients above 50 years old and below 50 years old. In patients above 50 years old, the reconstruction of ACL obtained satisfactory results.
