Summary
This study shows that four-strand hamstring autograft anterior cruciate ligament reconstruction effectively restores knee function and stability. Most patients experienced improved scores and reduced anterior tibial subluxation, with a low failure rate.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomedical Engineering
Background:
- Anterior cruciate ligament (ACL) tears are common knee injuries.
- Surgical reconstruction is often necessary for symptomatic ACL tears.
- The four-strand hamstring autograft is a common technique for ACL reconstruction.
Purpose of the Study:
- To evaluate the clinical outcomes of arthroscopic ACL reconstruction using a four-strand hamstring autograft.
- To assess functional scores and physical findings at least two years post-surgery.
- To analyze radiographic changes and failure rates in patients undergoing ACL repair.
Main Methods:
- Retrospective study of 34 patients with symptomatic ACL tears.
- ACL reconstruction performed using a four-strand hamstring autograft.
- Clinical outcomes assessed via physical examination, functional scores (Lysholm), and knee radiographs.
Main Results:
- 88% of patients had negative pivot shift and Lachman tests post-surgery.
- Average Lysholm score improved significantly from 59.3 to 85.29.
- 88% of patients showed eradication of anterior tibial subluxation; overall failure rate was 10%.
Conclusions:
- Four-strand hamstring autograft ACL reconstruction demonstrates favorable clinical outcomes.
- The procedure effectively restores knee stability and function, with significant improvement in patient-reported scores.
- While tunnel widening occurred, it did not correlate with progressive degenerative changes or clinical failure in most cases.
