Summary
The modified two-tension-band (MTTB) technique offers better knee function and fewer complications for patellar fractures compared to the AO tension band. Early mobilization is also improved with MTTB.
Area of Science:
- Orthopedic surgery
- Trauma care
- Biomedical engineering
Background:
- Patellar fractures are common injuries requiring surgical fixation.
- Traditional AO tension band technique is widely used but has associated complications.
- A modified two-tension-band (MTTB) technique has been developed to potentially improve outcomes.
Purpose of the Study:
- To compare the efficacy and safety of the modified two-tension-band (MTTB) technique versus the AO tension band technique in treating patellar fractures.
- To evaluate differences in bony union, functional recovery, and complication rates between the two surgical methods.
Main Methods:
- Retrospective study of 51 patients with patellar fractures.
- Patients were surgically treated using either the AO tension band technique (n=28) or the MTTB technique (n=23).
- Outcomes assessed included time to bony union, range of motion (ROM), Hospital for Special Surgery (HSS) scores, and complication rates.
Main Results:
- All 51 fractures achieved bony union with no significant difference in healing time between groups.
- The MTTB group showed significantly better HSS scores at 3 and 6 months postoperatively.
- The overall complication rate was significantly lower in the MTTB group, despite higher average costs.
Conclusions:
- The MTTB technique provides secure fixation for patellar fractures.
- MTTB demonstrates superior functional outcomes at 3 and 6 months and a lower complication rate compared to the AO tension band.
- MTTB facilitates earlier mobilization and improved knee function postoperatively.
