Objective:
To explore the curative effect of anterior cruciate ligament (ACL) reconstruction with tendon graft enveloped by preserved remnants.
Methods:
From June 2009 to June 2011,76 patients with ACL injury were treated, and the ACL was reconstructed with tendon graft enveloped by preserved remnants. There were 59 males and 17 females, aged 15 to 46 years with an average of 29 years. The causes of injuries included sports in 32 cases, training in 20 cases, traffic accidents in 16 cases, and other reasons in 8 cases. The average disease duration was 3 weeks (2 to 5 weeks). The results of Lachman test was positive in 72 cases and anterior drawer test were positive in 76 cases. The preoperative IKDC score was 45.9 +/- 3.6. The preoperative Lysholm knee score was 54.3 +/- 4.5.
Results:
All incisions got an one stage healing, and no early complications occurred. Sixty-nine cases were followed up, and the duration ranged from 17 to 31 months (mean, 23 months). The result of Lachman test was negative at the latest follow-up. At the latest follow-up, the degree of IKDC was A in 36 cases, B in 30 cases, C in 3 cases, no one in degree D. The postoperative IKDC score was 91.5 +/- 3.4, showing significant difference compared with preoperative score. The postoperative Lysholm score was 92.4 +/- 3.8, showing a significant difference compared with preoperative score.
Conclusion:
The clinical effect of anterior cruciate ligament (ACL) reconstruction with tendon graft enveloped by preserved remnants is satisfactory.
