This systematic review compared tibial suspensory fixation (TSF) and tibial interference screw (TIS) in hamstring autograft anterior cruciate ligament (ACL) reconstruction. Analyzing 17 studies with 7347 patients, it found no significant differences in functional outcomes or knee stability between TSF and TIS. However, TSF demonstrated less tunnel widening and superior knee flexor strength at 2 years (25.8 lbs vs 23.5 lbs, P = .002).
Key findings
- No significant differences in functional scores between TSF and TIS groups.
- TSF showed superior knee flexor strength at 2 years (25.8 lbs vs 23.5 lbs, P = .002).
- Greater tibial tunnel widening was observed with TIS compared to TSF (mean difference -2.40 to -1.61).
- Revision rates were higher with TIS (5.4%) compared to TSF (3.4%, P < .001).
Why it matters
Understanding the comparative outcomes of TSF and TIS in ACL reconstruction is crucial for optimizing surgical techniques and improving patient recovery. This review provides evidence that TSF may offer advantages in terms of tunnel widening and knee strength.
