Computer-assisted surgery (CAS) for anterior cruciate ligament (ACL) reconstruction shows no significant difference in patient outcomes compared to conventional methods. More research is needed due to insufficient evidence regarding the benefits of CAS in knee ligament surgery.

Area of Science:

Orthopaedic Surgery
Biomedical Engineering
Clinical Trials

Background:

Anterior cruciate ligament (ACL) reconstruction is a common orthopedic procedure.
Graft malpositioning is a frequent cause of ACL reconstruction failure.
Computer-assisted surgery (CAS) aims to improve graft placement accuracy.

Purpose of the Study:

To evaluate the effectiveness of CAS versus conventional techniques for ACL and posterior cruciate ligament (PCL) reconstruction in adults.
To compare patient-reported outcomes and objective knee function measures between CAS and conventional methods.
To identify any differences in adverse events and surgical time.

Main Methods:

Systematic review of randomized controlled trials (RCTs) and quasi-RCTs comparing CAS with conventional ACL/PCL reconstruction.

Searched multiple databases including Cochrane, MEDLINE, EMBASE, and CINAHL up to March 2010.

Data extraction and analysis by two independent reviewers, pooling data using risk ratios and mean differences.

Main Results:

Four RCTs involving 266 participants were included, all focusing on ACL reconstruction.
No statistically significant differences were found in self-reported quality of life (IKDC, Lysholm scores) or objective knee function at two years or more follow-up.
CAS was associated with longer operating times, but adverse effects were minimal and comparable between groups.

Conclusions:

Current evidence is insufficient to demonstrate or refute a favorable effect of CAS for cruciate ligament reconstructions.
Further high-quality studies with improved reporting are necessary to guide the use of CAS technology.
Clinicians cannot be advised for or against CAS based on the available evidence.
