Hypothesis
Interference screw placement through the patellar tendon portal results in less divergence compared to the anteromedial portal.
Conclusion
Using the patellar tendon portal for screw placement significantly reduces screw divergence without affecting clinical outcomes.
Supporting Evidence
- Mean tunnel-screw divergence through AM portal was 13.38°.
- Mean tunnel-screw divergence through PT portal was 7.20°.
- 82.9% of patients in the AM portal group had significant divergence.
- 82.9% of patients in the PT portal group had minimal divergence.
- Clinical outcomes were similar in both groups at two-year follow-up.
Takeaway
This study looked at two ways to place screws during knee surgery. One way keeps the screws straighter, which is better for healing, but both ways had similar results for how well patients felt afterward.
Methodology
Eighty-two patients were randomly assigned to receive graft fixation through either the anteromedial portal or the patellar tendon portal, with divergence measured postoperatively.
Limitations
Only sagittal plane divergence was evaluated, and a larger sample size is needed for more comprehensive results.
Participant Demographics
71 males and 11 females, aged between 18 and 60 years.
