Abstract:
Background:Anterior cruciate ligament (ACL) reconstruction is commonly performed to prevent decreased knee function and restore stability in middle-aged and even older patients. However, few studies have compared the long-term clinical outcomes of ACL reconstruction between older, younger, and middle-aged patients. The purpose of this study was to compare the long-term clinical outcomes of ACL reconstruction in older patients with those in younger and middle-aged patients.
Methods:A total of 352 patients who underwent primary ACL reconstruction between January 2003 and March 2008 were retrospectively reviewed and classified into three groups (group A: 246 [age, 20–29 years], group B: 72 [age, 40–49 years], group C: 34 [age, 50–65 years]). The mean follow-up period was 14.2 ± 1.6 years. Clinical outcomes were evaluated and compared between groups.
Results:The differences in the range of motion, clinical scores, and stability tests were not statistically significant among the three groups. The difference in the graft failure rate among the three groups was significant (group A: 16 [6.5%], group B: 7 [9.7%], group C: 6 [17.6%]; p = 0.040). In particular, when compared between the two groups, there was a significant difference between group A and group C (p = 0.036). The 10-year survival rates were 93.5%, 90.3%, and 82.4% for groups A, B, and C, respectively (p = 0.048).
Conclusions:Although graft failure rates were higher in older patients than younger and middle-aged patients, clinical outcomes of ACL reconstruction in older patients were comparable to those of younger and middle-aged patients in terms of the range of motion, clinical scores, and stability tests at a minimum follow-up of 10 years.
