Summary
This study found no significant differences in patient outcomes or complications among various total knee arthroplasty tibial inserts. Posterior stabilized designs offered slightly more flexion, but it was not clinically meaningful.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
- Clinical trial analysis
Background:
- Total knee arthroplasty (TKA) involves selecting tibial inserts, with various designs available.
- Optimizing TKA outcomes necessitates comparing these insert designs.
Conclusions:
- Current evidence indicates no significant differences in PROMs, satisfaction, or complications among various TKA tibial insert designs.
- While PS inserts offer slightly more flexion, this benefit is not clinically significant.
- Surgeons should base tibial insert selection on individual patient clinical factors rather than solely on functional scores or complication rates.
