Abstract

Purpose

To assess post-surgical outcomes in patients who underwent anterior cruciate ligament (ACL) reconstruction using a hamstring autograft with adjacent muscle retention, focusing on functional recovery over 24 months.

Methods

Patients who underwent ACL reconstruction at the Centro de Traumatologia Esportiva (CETE), Universidade Federal de São Paulo, were assessed for functional outcomes using the Lysholm scale at 6, 12, and 24 months post-surgery.

Results

We analyzed 151 patients aged 18 to 43 (mean age 29.2 years) who underwent ACL reconstruction. The time from injury to surgery ranged from 1 to 12 months, with an average of 3 months. The gender distribution included 101 males (66.9%) and 50 females (33.1%). Lysholm scores demonstrated steady improvement over time, with mean scores increasing from 87.92 at six months to 91.58 at 12 months and 92.21 at 24 months post-surgery. The standard deviation slightly decreased over time, indicating a convergence of recovery outcomes as patients progressed through rehabilitation. The range of Lysholm scores also narrowed, with most patients achieving scores between 85 and 99 by 24 months, reflecting functional recovery.

Conclusions

The findings indicate that ACL reconstruction using a hamstring autograft with adjacent muscle preservation leads to functional improvement, as evidenced by the steady increase in Lysholm scores over 24 months. The demographic analysis suggests this procedure might be a successful alternative in young adults, and timely surgical intervention is important for recovery. Future studies should investigate the long-term effectiveness of these outcomes and compare them with other surgical techniques.
